need a little more umphf!!


i used the same maf (mass air flow sensor) there is nothing wrong w/ the size of the maf its the same size thats feeding my 160 hp 3.0 and the same one that feeds the 245 hp 4.0v6, even the air filter housings are the same. whats holding the truck back is where ur air filter goes into the maf u hav a 90 degree bend then this cone dildo shaped thing (i call it an air horn) then another bend b4 the throttlebody. if u remove the air horn thing and look in it ull actually see its a large piece of plastic that allows probably 20 percent of the air into the engine to lessen intake noise and the computer is programmed to allow fuel for that opening only. you therefore have two options the way i see it...either replace the air horn w/ a piece of straight tube like a lot do when u read in the tech library, or you can shorten your intake like it did. i ran into the issue of my trk had a crinkle in the airhorn making an air leak, and was too broke to buy a tube. i removed the 90 degree bend after the maf and the air horn completely, took the maf off the airbox and installed it into the 45 degree bend that attaches to the throttlebody. was at the junkyard and on the contour they hav a round air filter element. if you remove the air filter and airbox lid you see where the wires run into the side of the upper airbox, take a knife/screwdriver and pop the faceplate off the upper airbox and ull notice its a ranger maf (all shiny and new looking not weathered too...) that has a screw on adapter for a round filter. take the two nuts off rob that from the contour maf and bolt it to the maf on your ranger and you can tighten on a round k&n style air filter element (3 inch diameter rubber flange.) now the question everybody has yet to ask me that i am fixing to answer, where is my iat (intake air temperature sensor)? i have mine still in the factory airbox like a moron currently, im going to get a vacuum fitting adapter and going to take the sensor out of the factory airbox lower and install it in the vacuum fitting adapter inline between the maf and bend b4 the throttlebody. so ur gears are pinned 4th at 90 approx and 5th u cant pull? i shift first at 35 second at 60 3rd is around 80 4th prob around 90ish (speedo stops at 85...)and i can cruise 5th fine and still pull 5th unless im going uphill. 5th when normally cruising tho and not fif (foot in floor) doesnt really feel good til im around 75mph, can cruise 5th at 60 level ground, but will run 4th if theres a hill or something coming up. i dont hav a tach either wish i did, heres another form of food for thought as well...my truck when i bought it said 62116 miles on it dont kno how many times its rolled over (no 6th digit on odometer, hell the only gages that work are the speedo and odo and the speedo is now acting stupid...) and the previous owner obviously beat the shit out of it (bald rear tires are a good indicator, and not from wear from burning rubber...) i had 2 inches of driveshaft slack in my pinion gear in my rear end and when i took it down i had broken ring gear teeth, so i rebuilt it not too long ago but after i let the odo read 72k miles. back then w/ all the slack in the rear my trans wasnt shifting right and i had no ballz when pulling. now i hav little driveshaft slack (1/4 inch maybe...) and about 1mm ring gear slack in the rear w/ the cover off after changing breakin oil and im pulling a lot better no slop between gears etc. moral of that story is when ur under the trk reading the id tag on the rear end to check your ratio out give ur driveshaft a twist and see how much play you hav in your rear end you may hav a minor slippage issue and/or overheating from worn gears/low oil level that could hold u back a hair. i love going fif w/ my little trk ill take pictures for you after work of everything to help you out when the rain stops lol.
 
well...its deffinatly not a tranny/rearend problem..there is not nich twist in the driveshaft and the only thing i know it needs is a new set of carier bearing.and i shift first at about 20-25/3.5k rpm..second around 50ish/4k 3rd to about 70(highway) then i skip 4th unless im pullin a hill.. ive had it up to about 90 in fourth around 4800rpm..she just doesnt have anything left...i could grab 5th and make my gas pedal a permanent peice of the floor board and eventually get 100....but id rather not push her wot that long...plus i dont have the money for a new car and license and everything else after i get a ticket..but about the intake maf mods..the contour..was it a 4banger or v6 model?would it make a difference?i see headwork and high comp pistons in the future...may possibly bore it and stroke it...but its a dailly driver..so thats alot of work to do in one day...lol..strip it work it rebuilt it all in a weekend...may have to get a shop to do it...cuz i know i dont have all the tools to pull it out and drop the tranny...but i know a few people who could do it in no time...so possibly within the next year or so:)idk yet..depends on what i can get out of it without going boost..
 
i shift cruising where you shift im telling you wot bout to blow shift point speeds
like im racing it, my carrier bearing is out and i hav one in the trk just need to put it on, waiting for all my chassis bushings and stainless steel brake lines come in first doing that plus shocks. bought my trk w/ a busted tranny so i did a junkyard tranny first off and rebuilt the top cap not too long ago (replaced shift rail plugs w/ pipe plugs new top cap gasket and new shifter bushings) and instead of dropping the trans again i cut a hole in the floorboard where the trans tunnel is. will get some metal in the future and make an access cover in case of future repairs needed. im going to build a long block and take my vacation and drop it in but thats down the road too, going to try and bump compression to 11:1 and port head cam port intake and header install leaving her n/a as mine is a daily driver as well. the contour was a 4 cylinder havent seen a v6 model to be honest you start talking v6 its 3.0 probe 3.0 taurus or 3.8 thunderbird, which the probe and taurus use square airboxes and dont have the adapter, the thunderbird maf is dif and again doesnt hav the adapter. if and or when you remove the air horn i was talking about you can pull 5th after grabbing 4th 90 aprox 5k rpm it will pull around 100 or a lil higher level ground in about 5 seconds and you can mash the hell out of the pedal, the engine doesnt care its really hardcore built. more worried of spitting a timing belt than nething, but i changed mine 10k miles ago so im good there for a bit. considering looking into an adjustable cam gear and playing w/ the settings of the factory cam to see if i can tune for a lil better hp or the much needed torque number for initial takeoff, it sucks taking off. only prob is i read on the sites that offer the cam gear not for ranger engine, makes no real sense i mean if i can adjust the cam 2-4 degrees either way thats all i need to see what will help power across the band. just cant make up my mind if i want to do the 2.5 crank or order a 2.3 crank milled down to accept the chevy 5.7 inch rods that makes a stroker that way, also looking into the volvo b234 16 valve headswap but dont really want to go thru the headache of fabricating intake/exhaust modding the head so it will work and then fig out wat to do ignition system wise since its 4 plugs instead of 8. been looking for all sorts of ways around everything but no help to say the least. well that gives you some light into wat i do in my spare time after pulling 8 hours at the local honda/yamaha motorcycle/atv/utv dealership lol.

well the shift points i gave are accurate to a point..30 is the max i can get out of it in first..2nd..maybe 60-65...but in those rpms shes got no more umphf left in her..if im really gettin on her i shift at about 5k no higher...it just wont pull after 5k..so when i shift it puts her right back into the powerband at about 3300rpm..i had it pinned in 2nd wrapped out bout to blow and was only doin about 60 ish..i threw it into 3rd and it threw me back in the seat till about 80 ish...wrapped out..no more left but it was only running a little under 5k..the cam im lookin at says it produces increased power from 2k up to 4500 or 5k which is perfect cuz thats where all the power is now..and i dont want to change the range of the power band..just improve it.. and the reason i wanted to go with long tubes for the headers was the slight increase in torqe..which will improve that little 4bangers performance more than a slight increase in hp over shortys..and plus with the shortys id have to do some moving around of computer shit that i dont care to mess with..but i do plan on tryin the intake out and have a go at it to see if i notice anything..if it seems to improve it a bit..then ill keep it and work on the fuel and ignition..and maybe by then she'll have a little more pep in her step eh?
 
Have you considered putting the truck on a diet?
Lowering the weight of the truck will make it feel like it has more power.
Of couse lowering weight can cost money as does increasing horepower.
Also, you don't notice much for ech little bit of weight you lose but the total makes a difference.
Lighter seats, losing the tailgate, going to a compact spare, lighter rims, fiberglass hood(if the money is there).
Unlike adding power, reducing weight can also increase gas mileage and make 5th gear more useable more often.
 
weight reduction isnt a bad idea if it wasnt so costly. steel rims are 75 a piece roughly and aluminum ones start at 100 or better, multiply by 5 (we all need a spare sometime!!!) and that hurts ones wallet. gateless isnt a bad idea for weight but horrible on economy. was loading a 300ex to work on in my spare time dropped it on the tailgate rather than the bed and tore the latch assy out of the gate on my truck and ive been gateless for a while, ive lost on average 3mpg. considering an air gate since i remember seeing on mythbusters that it has been proven the best form of balance of aerodynamics and drag and doesnt weigh that much to improve mileage. (tonneau covers and no/dropped tailgate led to the worst economy, leaving it up was better and airgate was the best surprisingly.) fiberglass body panels...here we go, looked all over the sites that showed fiberglass body in our tech library and a few other places, all i can find are flared fenders, not offroading my 2wd trk so thats not going to look good, plus the price hurts too to save a few lbs. thought about doing fiberglass bed panels and converting my front end to a 99 model so i can run hid headlights (my 92s are broken and front end beat to hell as the pictures later in the post show...) the 99 upgrade front end that includes grille, hood and front quarterpanels looks really nice, but 4 inch fenderflares and 900 bux really hurts, altho a cabover front hood would be cool and make my trk easier to work on. (esp that dam oil filter!!! hate turning my front wheels to the right and screwing on it from underneath at work on my lunchbreak...) back to stoke me, cam discussion, what cam and where you getting it from would like to see the specs, and also keep in mind we have the newer hydraulic roller cam head so make sure the cam is for our head, they changed from flat tappets in 89. header discussion, ford on one of the 4 cylinder ranger models offered a tubular manifold that supposedly yeilded a 15% flow increase, was going to look into them, then i noticed i hav an egr valve i hav to figure out what to do with...some say there is a version with the egr pipe attachment on the manifold, i want to do away with my egr entirely (no emissions in louisiana and im burning oil, just wat i want down my intake, its already black inside my intake ports...) that and i prefer fresh air in my engine not blowby from the rings or half burned exhaust gas, just runs better from my experience with other vehicles. i have never experimented with headers for exhaust tuning, mostly because the only other vehicles ive owned are a 91 acura integra that i only got to put 10k miles on (timing belt gone and bent 12 valves, sold her for 1k moved to fla for a bit on that money) and a 93 4wd ranger (i still own it) that i retired at 291k miles (no oil pressure and uses a qt of oil every 1k miles and throttle hangs wide open sometimes...) that had a 3.0 v6 a4ld automatic, and that v6 was crammed and wasnt going thru the headache of changing them out. i may be wrong when i say this but if im not mistaken longer tubes increase velocity from the exhaust and move heat away from the engine, increasing hp at high rpms, whereas short wrapped tubes increase pressure and heat closer to the engine making it strain more initially and makes a more complete burn, increase of torque perhaps? what i do kno is pipe diameter and how well the rest of the system flows affects how well the header/factory manifold scavenges. less choking equals more power. in the case of my old 3.0, the only thing noticable when installing a high flow larger diameter shorter cat and a higher flowing muffler single system or dual system was the exhaust note, not much more power to be had. the four cylinder (according to my assdyno...) is more responsive with a free flowing exhaust. i have the factory manifold installed, 2 1/4 pipe (opposed to the factory 2 inch) leading to a 40 inch classicchambered glasspack, then to a vx 40 (flowmaster 40 series copy, even the part numbers are the same just painted grey instead of black) to a tip all 2 1/4, my cat was removed by the previous owner and had a piece of rusted cast iron pipe in its place and the old factory muffler was full of what appeared to be where the factory cat blew out choking it up. i had a set of fart cans (2 inline welded together dumping in front of the axle) installed it wasnt too loud but ricy, moved to the 40 inch classic chambered that went the whole way out with the increased diameter pipe, nice and smooth was obnoxious so i added the 40 series copy to knock down the noise (no tkts plzzz....). its pretty smooth sounding but i will probably modify it more in the future, as far as my recommendations are concerned im not sure how long the factory precat/cat setup is on my 3.0 trk i had 3 feet of cats had them changed to a catco (magnaflow makes a good one as well) 2 1/4 diameter high flow converter (screen type could see daylight thru it) that was a foot long to help flow and id recommend increasing the pipe diameter to 2 1/4 and whatever muffler you want, packs are noisy fartcans are ricy turbos and chambered mufflers (flowmaster/magnaflow etc etc) have a good sound. keep in mind its not a v8 its not going to lope if anything itll be like a straight 6 monotonous smooth even tone just not as many cylinders (thank you mister obvious...). i do not recommend 2 1/2 inch pipe heat builds up too fast as the exhaust tends to hold the gas not expell it, the 2 inch is a lil constrictive, most guys dont recommend 2 1/2 pipe until your 4.0 or above in displacement for flow reasons. tuning...fun fun, we hav obd1/eec4 motors, were limited to standalone fuel management (feel like being an electronic engineer?) or chips. hav read on this site that bamachips offers custom chips based on what youve done to your engine, what the website is idk hopefully one of the other guys can help you. jet offers a chip as well seen it many times on jegs and summitracing not sure what its capable of, havent looked into the four cylinder much but i kno for fact superchips does not offer a chip for the 3.0, wouldnt hurt to look into a 2.3. since we are not obd2/eec5 flashtuners are not available to us (at least i havent found one yet...) so plugging in a box and pushing buttons like you could a bullydog tuner on your f350 isnt available (very sadly in my opinion....) the other issue is knowing if your tuning it right, my nearest dyno is in texas (200 miles from me...) i dont kno about you and your location maybe you are luckier than i am but if and when you go to do it that would be your best bet to make sure its done properly. later on when i get my new engine built and installed im going to put in a wideband o2 sensor w/ a gage to see how she runs and go from there on my own. for others to laugh at my expense i hav included a few pictures of my trk just to show how much of a project she is, but its slow and steady. aforementioned i hav pictures of my exhaust including the classicchambered 40 inch pack and the vx muffler, i have also included a picture of my custom shortram hot air intake system and the easiest way to rebuild the top cap of the transmission. new shifter bushings and the pipe plug shift rail plug replacement have been done as the picture shows. trk was picked up for 400 bux w/ busted tranny (stuck in 4th stripped gears and synchros). the other modifications including the 160 dollar jy transmission, jy doors and mirrors (passenger side from ranger/driver side from 94 f150) rebuilt rear end, new brake rotors pads shoes and drums including front wheelbearing rear axle bearings and seals. has new power steering pump/pulley, idler pulley, serpentine (a/c removed by previous owner) and timing belts, and new radiator. (broke hose neck when wrench slipped installing new power steering pump pulley...) in the backseat i hav 4 shocks carrier bearing 3 ujoints front sway bar bushings radius arm bushings axle pivot bushings leaf spring/shackle bushings and stainless steel braided brake lines and traction bars (courtesy james duff) to be installed in warmer weather (what a vacation it will be!) the rest is still in decision and as the money comes process...all my gages are stuck so prob going to go the custom route and cut my own dash out and go w/ autometer gages...well see...

you know..i just threw in 1800lbs of gravel in the bed the other day..and of course i didnt use 5th gear cuz i never got above 70...but i had to go up this pretty big hill that normally i have to shit out of 5th to pull....well seeing as i was in 4th already i shifted down to 3rd..thinkin i would have to in order to pull this hill...so about 1/4 ways up the hill i went ahead and put her in 3rd cuz i was loosing rpms in 4th...well she started turnin about 4900rpm...but i didnt have to put my foot more than halfway in the go pedal..so about halway up i started rollin into the gas..she just started pickin up rpms like crazy..b4 i knew it i was at the top of the hill doing 65 in 3rd and had to put it in 4th cuz i didnt feel like blowin the ol girl up...it just really suprised me that she would pull up such a large hill like that with about 1200lbs more than what she is rated for in the bed...the asz end was a little squirly around turns..but other than that she did just fine..all i can say is im proud of the ol gurl...lol
 
hey thanks for all the info...how do u put pics up on a post??i havent quite fingerd it out yet...ill put up a few of my ol girl on here and show you what im workin with!!thanx
 
easy upload your foto to myspace or photobucket or something, copy the image location (i use firefox browser so i right click and press copy image location all my fotos are on my myspace www.myspace.com/rurouni20xx). then when your in a post just put
and she is in there, for more than one foto just press enter and do another like so:


the 2.3 is a rather sweet engine, hit the sweet spot just right in the cam and you can feel it, esp with a free flowing exhaust. i have a bridge i play hell with on occasion going 60 in 5th shell drop down i can bottom the throttle and shell still lose some speed but make it but i drop it in 4th shes climbing the whole way. 5th gear in the m50d tranny is def an overdrive to say the least.

so im getting the crazy idea to try and do the tbird swap....granted if i can find a motor in good shape that i dont have to completely repbuild from the case up...how much of a u know what is it gunna be to swap in??I have a buddy who has a buddy that just threw in a new motor in a 05 dodge 1500 in about 3 days....i know about the tech page and all that stuff..so ill be drooling over those pages after i get off work today..i jus wondered if you had any info as to what i should expect to run into during the swap...things i can use off the old lima to the new turbo motor...and so on....
 
basically from what ive seen its the motor plus engine wiring harness and ecu. u start bumping the boost beyond stock your talking dyno level tuning. going to do a 3.3 stroker turbo on my 93 3.0 truck later so thats my turbo project in the future (had to be put on hold for my 92 2.3 truck...). i was contemplating that swap or building a 2.3 turbo motor and doing it from scratch but this is my daily driver so the downtime to do the swap and tuning from a scratch motor is out of the question. depending on what tools u have etc and how diligent and religious you are you could do the swap in less than a week id say, no experience there talk to the guys in the forced induction section they can help you a lot.
 
well...this project is on hold as of today...i just got laid off...so im gunna be driving alot and job hunting..i knew it was comin though..should have started lookin a long time ago..oh well..for now ill jus do all the research i can, but no more tuning or tinkering on my truck for now...she is running fine as is so i ddont want to mess it up and be out a truck and a job!!thanx tho for the info..if i can ill upload some pics later..
 
sorry to hear that but good luck in the hunt, looking forward to talking with you more in the future. if your interested in engine building, fuel injection theory, turbocharging (size selection and installation), and ignition systems check out the books from sadesign at cartechbooks.com. ive read several of their titles and hav helped me alot when i was designing my other trk. rogueperformance.com also has the fuel and intake runner design formulas as well for free. i own turbo: real world hi perf turbo systems, how to build high perf ign systems, designing and tuning hi performance fuel injection sys, engine management advanced tuning, and engine blueprinting, very handy to say the least. found one or two at autozoo and ordered the rest online, fig it would help you get on your feet when it comes to understanding these things lol. only other one i want is automotive wiring just for desk reference.
 
for ur intake for now i would probably take the baffle out of it. In the straight part that is all plastic is this big funnel that some how is supposed to direct the air flow but i dont know how it just takes up a lot of room. If you just take that black plastic piece off and take the baffle out for now until you get a better intake system. Im just saying its a cheap fix until you do something about the intake. I noticed a little difference in my 2.3 when i had it. and also if ur check engine light comes on then just detach the battery cables for about 5 minutes or so so that the system can reset.
