yea first post of this thread:
https://my350z.com/forum/na-builds/3...-roadster.html
279-250.6whp = 28.4hp
https://my350z.com/forum/na-builds/3...-roadster.html
Stock 2006 Rev-Up Roadster, 220whp
Then:
SGM Intake
SGM Cat-back exhaust
240whp
And Then:
SGM Intake
SGM Cat-back exhaust
Pulstar spark plugs (essentially just adding 3 degrees of timing)
Aftermarket y-pipe (don't even know what kind it is to be honest, it was given to us. I cut it apart and grinded the collector smooth and welded it back together, if that matters).
250.6whp
Finally:
Addition of these prototype long tube headers that are based off of our Koni race car headers.
279.0whp, 20ft lb gain across the board!!

If a bolt on was proven to give good whp and it was $200h0 like these long tubes I'd do it. I haven't even bothered with any boltons on this car because I've seen so many mixed reviews I'm just torn. FI does give good gains but I drive 20k a year and can't afford to have any down time of worry about my motor blowing when I step on the gas. I feel that if its not FI from the factory its not meant to have FI on it. If a revup could get near 300whp on a legit dyno with these headers and a good set of cams I'd spend the money.

agreed with previous post on price. However i was speaking of their website that everything is overpriced. If i wanted to keep my car full bolt on then yes i would def buy these headers. With just these headers would put my car over 300whp. But then i think of adding proper aggressive cams for the headers and a tune plus install and WOW at all that $. However now while typing this and just spoke with Bobby @ CIN and what he would charge me to install and tune everything i want for NA and umm it seems doable. Great info. And Z1 i will call them tomorrow to see. Thx for insight
