do i need a new fuel pump?
Friday, June 24, 2005 1:51 PM
im running a 1995 2.2L cavalier with a t3/t4 turbo and intercooled. im using my stock injectors with my stock fuel pump. im using a maual boost controller and i have it set at 0. the car cuts out under full throttle obviously cause of fuel issues. do i need a new better fuel pump? will this help? i read that no other injectors will work in my car because its side fed, but i could use a mf2 or an eic but i have no idea where to get it, how much it cost, and how it actually works. please let me know what to do, im sol.

I have a MF2 for sale. Works awesome. Would sell it to you for 300 bucks with everything minus the MAP sensor, which you can pick up at any Auto parts store for cheap.


O noes!

have your fuel rail converted for top feed injectors, and run larger injectors, fuel pump, etc etc. that's what i am doing.




I was a retard, and now I'm permanently banned.

this is my brothers car by the way, a 95 2.2L ,don't be fooled by my reg. sry. how expensive is converting to top feed because he doesn't have a lot of money. he does already have larger injectors and an fmu so...

if its a side fed, which injectors is he running exactly?

To do a Top Feed conversion is expensive.

If your bro knows a machinist by chance, he might be able to help him out.

Luckily I've got a machine shop willing to help me out (for cheap), but I still wont do a top feed conversion.

You would probably need an SAFC-II to help tune your idle, etc.

way too much money as far as I'm concerned.

it is side fed, and he is running the stock injectors. im 100% sure the top feed conversion is out of the question but I guess there is still hope. i dont remember his name i think it was alex16cav or something, he had the 2.2 turbo green coupe. his setup was basically the same except he was using a mf2 if i remember correctly. as far as i know his car was running perfectly.

yeah an MF2 is an extra injector controller.

the SDS EIC is capable of 4 extra injectors, meaning 1 extra injector for each cylinder/ intake runner.

IMO the 4 extra injector method is a more sure-fire way to know that each cylinder is receiving the same amount of fuel. (Granted that all your injectors flow the same)

its a band-aid method, but there are plenty of people using it.

check it out, I'd still recommend getting a fuel pump of some sort.
