Keep the S4 keg, upgrade to S5 rotors. I dont see a real reason to use an RX-8 shaft unless you like spending money on something that could be chewed up (seen the insides of a blown renesis and old bearings....its not pretty).

Streetporting is a good idea, choose your apex seals wisely, oem is usually the best.

What header are you going to be using? Any NA with no cats is going to be loud, a header is louder, and no presilencer (like found at racingbeat) is going to be illegally loud and draw lots of attention from johnny law.

Though have you confirmed if this car is really blown? "Just shot off" is not really consistant with a blown motor. Blowing a motor feels like you just got half your power stolen from you and the engine shakes like a beast. Ive DD'd my own FC for a week on 1 rotor, started and ran every day on that one rotor until it was removed and replaced. Sounds more like a spark or fuel issue to me, though confirm its blown by pulling the plugs and just listening to the sounds coming from them. Wooshes indicate 'healthy' seals, while nothing at all means blown.

Good luck and hope my post helped.

i know the preves 2 oners of the car and both complaned of under power the stock motor has 126K on it id say it ant really blow up didnt smoke any except for the useal cold start. i just figer it would be best to go ahead and rebild it and im perty shure the clutch is gone the guy that had it last sed it was and i know this is the car he lernd how to drive a stick on so so you know how that gose

why would you keep the s4 case? insted of giting a complet s5

and from what i was told is the Rx8 E-shaft was a lighter shaft and had better oiling

as for my sils im planing on just the classic kit nothing big with up graded springs

im just going on what i have been toled not trying to question ur resons just trying to lern
