I got some manifolds, throttle and maf for sale! Gotta go! Did the same thing to my car and it gave it a nice boost particuarlly at high rpm. Pity the heads are so crap though. It also lost the ashtmatic engine going to explode feeling at 5000rpm. Now revs to 5500 with no drama's
edit if you buy em install will be free

youll be leavin a happy man at 5000rpm
