Guys, Im picking up a car next week. Planning on an On3 turbo. Here's the combo so far, what changes do you recomend besides bigger injectors and maf and higher rear gearing? No automatic suggestions please! This wil be just a street car/ weekend toy, not drag racer. Will plan on keeping boost level around 8-10 due to the block.

Here the info....

dss level 10 block that is .040 over actually making it 333 in. 9.6:1. It has a dss 331 sx rotating assembly w/ the main support, all forged, it has a mild crane 2020 cam. It has edelbrock RPM heads with port and bowl work they have ferrera 2.05 int. and 1.60 edel. int. It has 1.6 harland sharp rollers, comp 6.050 pushrods ,new F.R. lifters, new comp. timing set, new f.r. h20 pump, trick flow track heat int w/ 70mm. T.B., moroso kickout 8 qt. pan,pro-m 75mm maf. bbk 1+5/8 long tubes 2.5 h-pipe and mac 3in. produmps. Alum. drive shaft. 373 rear

Thanks for your help

Got the car. Already has 42# injectors, so i'll probably stick with them for now. Can a Pro M maf be converted to blow through?

what maf and injectors you running? keeping full exhaust because i hate smelling like exhaust so i just added 3" flowmaster tailpipes mated to 3" produmps modified to accept tails.

I think it depends on the meter. Call pro m and ask because they are the ones that will have to program it

i see no reason why to ditch the a9l. this is not a race car that needs every last ounce of hp. no reason the stock ecm cant handle this setup with a good tune

Ive tossed a motor or two on the A9L. It just does not have the ability to tune for boost reliably. Lets not forget, it was designed in 1986 for a 225 HP car. You cross over 500 HP, you are playing with fire. Do what you want, but Ive learned my lesson to many times....

I think you need to:

a) find a better tuner

or

b) learn how to tune if you're tuning it.



There are literally thousands of 500+ rwhp boosted fox bodies with stock ECU's

I would run a HPX slot maf and 60's. For a fuel pump, throw one of the aeromotive 340 lph pumps in there.
