Take it to a mechanic....

They are designed as 'drop in' camshafts. There are no other parts required to do the job.

I would suggest replacing the timing belt and installing adjustable cam gears (if you want to go that way) as the same time. If your going the replace the cam belt, replace the idler pulley and the rocker cover seals.

Timing belts are not something to be played with by beginners, if you need instructions take it to a professional and let them do it. Will cost alot less in the lone run

set of after market springs and a reshimm to get clearances right!

Yes there are. You need to re shim the valve train to get the clearances right. So at minimum you need spare shims for that.

Also, if the motor is standard you are wasting your time installing type B Poncams as it won't improve performance in any meaningful way, just reduce midrange torque. If you must change cams the type A are a far better bet.

The exhaust cam on the Tomei's actually opens at 65 BBDC - the same as the stocker.

Actually the difference between the A & the B's is all in the exhaust cam - it has an extra 8 degrees duration on the B, ie 260 rather than 252.

That would make perfect sense. When i tuned deano1s GTR on wednesday Pulse had the cam timing all wacked. Inlet Was retarted Nd exhaust advanced. We set it all to 0 and made and extra 25kw and gained 60kw in the midrange.

Full boost was 5500 and now its 4300. 19psi.

what turbo is deano1 running?? worthwile mod for gtr running gt-ss pushing 300rwkw?

Deano 1 is running his stock N1 turbos. Steel wheel obviously.

People have made lots of power on stock cams. I think close to 600hp. But with big ass turbo's.

My car has the same turbos as deano s but with stock cams, mine is more responsive but doeant have the top end as deanos.

My car made 285rwkw

deanos made 300.2kw

[R31Nismoid]

How much boost? Im making 280rwkw, factory cams with GT-SS's on i think 16psi

[Moodles2]

Can be done with the engine still in, but if you screw it up, I've been told its an engine out job

Deanos is on 18.4psi 11.2afr.

Mine is on 18psi 11.2 afr. Both have really safe ignition. And as u can see reqlly safe afrs
