Thread: 3.4" pully

before you put money into a PCM, you really should take the heads off to see if you've chipped a piston. you've been knocking since the 3.4 pulley was put on and it might have just taken its toll on the motor.

As for PCMs, i've heard intense i a pretty good choice. i've also read that zzp's tend to blow a lot of people's motors.

that's a good point. i was a little out of it when i posted that.

anyways, here's the thread he's talking about:

Which is the safely modding thread...

most people around here just go for whatever pulley they can fit on there and dont check for knock or if they do, they get it "tuned out" aka pull all timing and run say 12* at WOT.

Just stupid....

ok sry guys reread that modding post and it has all my answers pretty much. ..checked my plugs there not chiped so thank god my pistons are good. any review on that mag snout from pfyc? i no i need new bearings and i want to change the coupler. when i bought the car it came with a 3.4" pully with no mods besides the catback and cai 180* start and msd coils. they stiped the the snout with they took the old one off it looks like cuz i lost the breather nut and trying to put a nother one in and it fell out . i am waiting on my slp heads and problems i should be worried about in the instalation?
