i have a question.. which has been answered but i dont know the name of the thread..
sorry guys..:(
what makes the 88-89 EFI model have more hp than the 86-87 i know its the pistons and header.. what else?
i mean if theres anyway that i can just swap those selected parts over to get that much hp?
from 110-125ish???
thanks in advance

Fuel Injection :)


edit: Whoops thought you had carb. I don't think the headers are different though. Yeah if you just change the parts over that should bring you up to that hp.

I thought you had a carbed motor asking why the FI motors were faster. :) my bad.

I have MSN [email protected]
I don't know too much about FI cars since I have my carbed 3G. I have to go take a test at this college soon so I won't be home for too long.

wikked.... I'm no expert on EFI 3G's either b/c I don't have any, but I think it's the combination of diff. header, and the pistons are a higher compression piston. I'm pretty sure the ECU is different as well, which might also account for the increased hp. After that, I'm just as clueless as you and Mike.

OK here we go different header higher compression dual stage throttlebody different ecu and different emmisions controlls any thing else

4-2-1 header as opposed to 4-1 header (better lower end torque), dual stage intake manifold (shorter intake runners that open at high RPM, give better high-end torque and thus more HP), and 9.3:1 compression as opposed to 8.8:1. I don't know what effect the ECU has, except it probably lets more fuel flow at higher RPMs due to the faster air from the short runners.

4-2-1 exhaust manifold, not header
