Bye, Bye Skyline. Hello...

Yep, the R is the upspec'd model, but engine wise they are identical.

Only differences are electric sunroof and audio options like cassette player and multi-disc changer.

IMO - KW is for bragging to your friends.

If your like moir, the aim was for safe full potenial of my motor, they are seriously detuned for EPA and the real potential of the RB & SR can be realeased with good and informed mods.

Yeah I'm all for getting the potential out. However some people tend to forget that they don't necessarily need over 200rwkw even though 200rwkw seems the bare minimum these days. You certainly don't need that power on the street, as that is more than enough to easily break lots of laws before you know it. With circuit, the quick times usually comes from the driver and suspension setup. With drift you can easily get sideways and stay sideways with the right setup and tyres (look at the NA Hachis). Drag racing is the only event which relys on big power, and how much of you go out to street meets regularly?

Got to agree with you there.

So what is a safe rwkw for the sr20?

[Thunderbolt]

Well you can't really put a figure on it. To drive an SR safely, you need to keep it below 7000rpm ideally. Fortunately the SR has bucketloads of midrange torque, so you don't need to rev the crap out of it.

The stock turbo (on S15s) is fairly good for producing a useable power band, so people shouldn't have to feel they need to race out and by the latest Garret GT28RS or something.

Depending on the dyno, you can get up to around 200rwkw with a fuel pump, boost increase (say to 14 or 15psi), intercooler, exhaust, tune etc.
