Hey guys I was just wondering if anyone knows the max amount of mods I can run on my 95 5-speed w/out having to upgrade the injectors.

So far my mods include....

OD pulley...
Raised SC top...
Full exhaust w/kooks headers...
UD pulleys....
85mm TB....
76mm MAF....
MP inlet Plenum...
and a cold air intake....

I was looking into a set of port and polished heads and was wondering if my fuel pump and injectors would keep up with that the "new" heads and the current modifications. Any help is appreciated!! THanks.

I would say you are there, get a chip/injectors/fuel pump/FPR and keep it safe. It is expensive if you melt a piston like myself.

So I should do the chip and injectors before I do any type of headwork?

Thanks for the info...

There is one way to tell for sure and thats to dyno and get some A/F numbers and see where there at. The other thing is a 95 has 36# injectors stock.

Thanks for the info guys, I was hoping someone would chime in who has tried it and is still running lol. Would it maybe be alright to put the stock size SC pulley back on and then put the heads on? Kind of a swap until I can get the money to get it tuned.
