yeah I would stay with ngk v power 7s and replace them every 3 or 4 oil changes. No telling about the head gasket though and you will need a shop with data logit to tune that ecu. It good be a gold mine or a lot of trouble. You will not know until you try and fire it up. I would guess some where around 320 to 340 whp from the sounds of it so far maybe more if you have a great tuner. Good luck with it. A exedy stage 2 or whatever is 300 to 400 bucks will hold -- I run close to that power level now and never had any trouble with it.homeslicej2 wrote:HKS' website states that turbo is rated at 360/370PS which is roughly same as our horsepower measurement. It's about 355-365hp rating on the turbo. As for the clutch, what others have said, and the plugs, your heat range should match your power and boost levels.

maybe maybe not. the apexi ecu will get a rapid CEL when it detects spark knock. I would for sure pickup a wand if I was you so you can monitor stuff. It is for sure worth it if you have the FC which I do as well. I believe I would double check the tune though cause things like backpressure in your current exhaust on your car could be different than the car it was on. I am curious to see what power level you make. Did you pay the same price we all pay for these engines? like 2 grand or so? My engine had an aftermarket KIDS ecu tune on it as well so I think tuning in Japan is an everyday occurrence. They play and change all their cars a lot more often then people here do.MES14AN wrote:LIke i said its got a apexi ecu fc commandor but i dont have the monitor part to view.This set up is mind boggling cuz rated 8 plugs are for 450 hp applicationand the clutch looks stock. If you look at the fly wheel either the person who had it rode the clutch / not letting of the clutch right away or the clutch cant hold the power & and I can tell the clutch was recently put in cause it looksalmost brand new. Im i going to have to get this retuned?
