depends on how much boost you will running to achieve 320rwkws. i found anything over 18/20 psi my stock coils broke down. bought a dozen 2nd hand coils from the wreckers and sau and they all broke down at high boost. so i think it depends on boost/ age and condition that they are in.
when i recently purchased a garrett gt3040 600hp turbo from gcg in sydney,first thing he asked was if i had aftermarket cams or any head work to get the best out of it. t04z thats a shit load bigger turbo than mine. mine makes 274rwkws at 17psi and 346rwkws at 24psi. i would think a t04z should be making 350rwkws at 20psi and close to 400rwkws on 25psi???
thanks for the kind comments gt-rz! you hit the nailon the head! im sick and tired of bumping this thread back by reducing the price, it just conditions people to hold out longer. i know the market is flat. i have the car advertised on carsales at $21497. but i will definately negotiate with an sau user/member. i can hardly believe that ive had no bites. this car is an absolute weapon. sure you can pickthem up for $10/12k now and i dont expect to get the full cost of modifications back but i think the price is quite reasonable. you couldnt build yourself this car even buying a cheap stocker you would be up for over $30k!!!
no its not lol! have to use low boost to overtake , can only dab the throttle otherwise you end up doing 120mph! toyota corollas beat you of the mark at the lights e.t.c. 350kws better in awd package i would think. dont flame me just my 2 cents.
i just tell them that if my 2.5l makes 346rwkws your 5.7l would have tomake 788 rwkws to be any where near as efficient. and seing how gts-t weighs only 1370kgs and a vx monaro weighs in excess of 1700kgs,i rest my case. had a mate at work tell me that even though he concedes that my skyline would beat his vx gto monaro in a race , that his mates 10 sec vl would destroy me lol! whats he trying to say about his car?
if it is of any help, im running an exedy extreme ,had it for 4 years now 225 rwkws no probs , 260 rwkws no probs , 280 rwkws no probs and now 346rwkws stillno dramas... occassional drags and street driven.
