For the 4.0? Not yet, only the 36 pound injectors

If you tune there is no need to match injector to MAF. You do need the MAF air flow curve from the manufacturer. I just saw a Tweecer RT for $250 on Corral. They are $450 new.

I can't find a cheaper pulley, wanting a 2.6" I am running a 2.8" and getting 7lbs at this altitude, about a 10% reduction in boost. I got more work to do before it will take more boost.

I have a 2.65 (ish) for my m112 I'll give you for helping me tune, if you'd be so interested.

I'm probably going to use a mustang maf. Not sure where I'll find the curve though.. maybe late model restoration will have if for their maf's.

Now I wonder if injector size matters if it's a v8 36 pound vs a v6, 36 pound..

I'll definitely look into the tweecer rt, I wonder if I have an account on corral.. it's been ages.

Side note, I've been thinking recently, won't my blower put out more boost because it's heavily ported? Or does that just help flow at higher rpm?

I would think you could search and find the MAF curve again on Corral. Some are already in the Tweecer software to load, I will check.

The injector size does not matter as long as they are big enough, you input the size with Tweecer and it fires them right.

The ported blower should put out more boost, but the porting is more fine tuning, not like it's going to put another 5lbs out, likely a pound or two. I think I would go with a larger pulley than 3" which sucks for the cost of them cause you'll likely want to change it.

Nice offer on the pulley.

Might need a touch of help on this one, the fuel lines are way to close to the intake to use the stock fpr, so that completely rules out that whole side of the fuel lines, I have a few ideas on things I'll try with my spare lower intake/fuel rails. But if anyone has any ideas or insight, that would be great! Pics attached of the amount of room I don't have

Where spacer one sits compared to the fuel rail


Where the fuel pressure regulator sits, under the m112 adapter


And where the feed line sits on the uderside of the adapter plate.

Spitballing:

Add more height for clearance cut-out hood - laughable

Cut FPR, weld, relocate.

Eliminate FPR use adjustable in a remote location. A bracket could be made to hold the fuel line in utilizing the existing bolt holes.

They idea is remove the stock fpr, maybe add 1/2" more spacer (yay more $$$$) and try to make custom fuel lines

I've got the fuel lines figured out (for the most part) pictures will be mid next week. Still working on an m112 3.2-3.5" pulley for not $100+

Carbed boosted guy, cool...iv boosted a lot of different cars and trucks over the years, from cheap FMU set-ups to standalone bigger hp set-ups. Always wanted to do a super budget carbed turbo set-up on something cheap just haven't got the chance yet.

Anyway.... what wheels and tire size are on lowered ranger? whats the suspension set-up on that same ranger? what are the plans for that ranger and if you have any other pics of it please post them.

Yeah not many people my age who can tune a boosted carb!

They're 17x9.5's all around they're djm dream beams with shorter coils, axle flipped rear with disks. Plans are to sell it honestly, more pictures attached



Custom seats in it

Off the top of my head.. 265/35/17's all 4 corners. Off the top of my head I don't know the back spacing (I have 1.5" spacers upfront because I wanted wider tires) they're konig something's lol I've had them for years now, perhaps konig lace wheels.


My turbo ranger has 98 cobra mustang wheels on it, 17x10 rear 17x9 front, old bad picture here tho

Look into what? The offset? Wheel model?
