Is it possible to reach around 200rwKw on a Z without using force induction?

If so what is required?

 

how much is that in U.S. HP? if it's close to 300 it's possible

 

270 Hp

 

very possible

 

And what parts are needed and how much?

 

Breathing bolt-ons (intake-opt., headers, plenum spacer, test pipes, TD exhaust, etc.), and proper tune. $$ depends on brand and labor rates, but it's not as cost effective as other cars. Many say N/A cost ratio is $100 for every 1 whp gained.

 

do you have a baseline dyno to compare? All dyno machines are different and its not worth comparing numbers between different dyno machines.

I got intake, plenum spacer, headers, y pipe, exhaust, cams and ecu, revving to 7200rpm.

I got 192rwkw before headers/cams/ecu and 217kw after headers/cams/ecu. then again all dynos read differently, but at least i can see my gain because i used the same dyno before and after.

Theres bit more to be had by ditching the stock cats but I'm keeping them in for the obvious reasons (haha!).
