2.0l with holley 2300; jet sizes?

[jlohmann]

I'm having WAY too much trouble with the factory Aisan carb. I've found a good holley 2300 at a good price. I've searched around (TRS and google) to try and find some info about what jets to run in this carb on my 2.0l engine. Seems to me that the general consensus from the 2.8l guys, is that a #53 jet works best on that engine. Jets are fairly cheap and I was going to buy maybe 3 different sizes. But I was wondering if anybody has any experience or input on which jet(s) to start with? I was thinking #45 - #47?

Also, I'm planning some other upgrades in the near future. Head and intake porting, mild cam, header and good exhaust. I'm not shooting for race engine at all. I don't plan on trying to pass all the little tuner kids in my neighborhood. In fact, I'm only trying to pass gas stations. Efficiency and mpg's are the key here.

Thanks,
Joe

Not sure about the jet sizes...maybe Mutant Pony or Kenneth can answer those questions...

But if you're looking to improve gas mileage then you might want to instead of carb go Fuel Injection...there is a bit more to it than just adding the FI hardware though...but you will get about 10 more HP right off the bat and probably about 3-5 more MPG that way...but you would need to also change the head and use a 2.3 head...but that's not a bad thing...

Last I heard from Kenneth he was in the process of swapping over from carb to FI because of carb problems...but I'm sure he's still around...and Mutant is working through some personal issues but still posting...

I've been considering this swap myself...just don't want to go there if I can get my carb working right...

I'm running 55 main jets and a 6.5 powervalve on my 2.3, on a 2.0 53 or 52 main jets should be about right (45-47 jets would probably be way too lean).
I put the carb back on my truck (couldn't get the efi to work, and I really needed my truck back), come to find found out that my carb problem was due to a warped carb adaptor plate, I milled it flat, no more carb problems for me, still getting a city/hwy average of 23-24 mpg with the carb.
On another note I don't know if the 87 2.0 is a roller cam or not (you'd have to pull the valve cover to see), if it's a flat rocker cam, find a 2.3 ranger 88 and up and get the roller cam and roller rockers from it, it will save you quite a few bucks than going aftermarket, you probably wouldn't notice the difference between a mild aftermarket roller cam, and a stock roller cam as far as mpg goes.
That's my .02 cents!

Glad you figured that out Kenneth...and didn't go to the dark side...lol...

Still haven't tried what you suggested...was going to do that today (rev engine and cover the carb) but the battery ran too low...had to study anyways...
