From stock.....

[psycho121]

I have a 1992 Z34. As far as I know, everything on it is stock, except for the filter (K&N oem replacement) and the mufflers which are probably just off the shelf (nothing special). I want to give it a bit more kick, but nothing excessive (no twin turbos or nos ). What should I start with? I don't have a ton of experience working with this engine, but I am an airplane mechanic, and i do have the GM manuals for the car. As a side note, the exhaust sounds like it has a rattle in it, but only at 2000RPM. Took it to a muffler shop, and they could not diagnose the problem (hence the new mufflers )

Thanks!

Its normal to have a rasp around that RPM, though usually 2200-2400. A resonator will help. Now if its actually got something in the exhaust, it would fix it but RPM based sounds like the rasp we all know and love (ha).

Performance chip is the easiest way to get more performance out of the car. Porting and timing require a bit more work.

Ok, I heard about the FFP guys, but they've shut down. Any suggestions on another brand? Do I just plug it in and go?

Thx for the quick reply!

I sell the chip FFP was selling (even when they weren't supposed to be), since I was the one that made them to begin with. UD pulley, there is nothing yet but there may be soon. Otherwise used is the only option for the pulley.

dont know about the rest of yall, but i didnt notice much gain from the UD pulley.

personally i think the best mods are as follows:
-Cold air intake such as a FWI
-cat back exhaust replacement with 2.5" piping
-ported TB and intake manifold
-custom tuned chip
-some nice tires and weight reduction

now it wont make the car more powerful, but suspension mods i feel are real important. things like STB's (strut tower brace's), GMPP trailing arms, kyb struts make for a very nice driving experience. along with the right sway bars... i was luckey enough to have a Z that has the better sway bars.

where can i get that tuned chip for a 1996 z34 at?

[SappySE107]

96 doesn't use a chip so you won't find one. You can get a DHP or HP Tuners programmer however. I was told to use a 97 ECM for my 96 GTP.

aspracing makes an underdrive pulley and mrzperformance is working on one, along with a billet poly dogbone.

What will that do for me?

If I get this chip for my 1991 will any mechanic know what to do with it?

thanks
