update:
this past weekend, i attended a local z club 'mod party' where we all brought what we needed to install, and all the guys (most have a lot of experience modding z's and g's... a couple guys have over 500whp) chipped in to help out. i already had my cold air intake installed (which did add a noticeable amount of low end power), and i added my plenum spacer and race pipes. the spacer only took about 20 minutes.... the race pipes took about 3.5 hours, as just about the entire exhaust system had to be dropped to remove the cats and add the pipes.
the result? it's been less than a week, but i notice a big gain in the mid-high end power band. i had the top down and up to 125-130mph on a major highway in no time. of course, with no cats, it's pretty loud now.
but the spacer is supposed to add 8-12 horse (dyno proven), and the race pipes add at least that much.
just one thing: most guys in my club got the motordyne iso thermal spacer. get that one, if you're going to do it. i got the z1 spacer, and had a number of problems. z1 is a top-notch z/g tuning company in GA, but pay a little more and go with a company like motordyne that has years of tuning/racing experience.
here's mine (and my leg sticking out from under, lol)
and a coveted 370z even made an appearance!
