3.4 dohc performance info

[dohcfiend]

just figured i'd throw a little out here for you guys after testing some hunches.

1. mms headers do in fact fit 1st gen wbodies if u have 96-97 heads or engine. only thing i had to modify was i had to remove 1 piece of heat shielding from the firewall.

2. the neutrally balanced getrag 282 flywheel for a 88 fiero does interchange with the 284 flywheel

So I could get a set of the headers and just change the flange?
Post a link to headers please.

ok, i'll click some pix for ya and post them. though you will not see too much b/c i wrapped them.

here are a couple pix:

Hey fiend, who is this MMS and do they make any headers that would fit into my 94 GTP? Are they any good?

[dohcfiend]

hey, mms stands for milzy motorsports. these headers are in fact in my 94 gtp right now. unfortunately they do not make headers for the 91-95 lq1, only 96-97(or just swap on 96-97 heads to a 91-95 lq1).

my engine is newly rebuilt and i still have to put enough miles on it to break it in be4 taking it to the dyno and thrashing it. one other guy put a set on his relatively stock monte and netted 12hp to the wheels untuned and hooked up to his stock exhaust i believe.

there is a catch though. he is not fast at all, actually he is quite slow. i think it took me 2 months to get mine. also his prices are not cheap, i think it is 700 and some change for a uncoated set. although i got mine much cheaper than that in exchange for beta testing them on my gen1 wbody .

it was tight as you can see by the pix but they fit. only modification i had to do was remove the upper heat shield on the firewall and i had to lengthen the wires for my 02 sensor.

p.s. b/c of the fit and installation, they are not equal length or anything, just a FYI.
