are cams needed to hit 600rwhp on tt?
are cams going to be needed to hit the 600rwhp mark on a greddy tt set up. of course forged bottom end is needed but will it be worth the money to do larger cams while i have the motor ripped apart? i have a line on someone selling r-tune nismo cams for 1/2 price but still, would i need them? thanks

oh well. there is a reason i call myself overZealous one. i just bought them anyways, to dam good of a deal to pass up, hahah. but still looking for insite to the original question.
You obviously saw my other post.
600+hp is possible w/ stock cams, however aftermarket cams makes life much easier. Much, much easier. The NISMO cams are some of the smaller cams available. But a good deal is a good deal.

Cams, and possiblly some very serious headwork will be needed to exceed 600whp. Ask SGP about some of their build-ups. All of the 580wp + cars had oversized valves, cams, essentially, a fully built head...in addition to the bottom end stuff.
The Greddy TT's are going to be really struggling to generate the sustained airflow needed for 600whp +. Doable..but you should probably upgrade to a 20G wheel while you are at it.

ernies car was makign 570rwhp at 20 psi with nothing but pistons, rods, and a greddy turbo kit.
IMHO 600whp is would be super easy if using a FCON and a better intake manifold then stock... I bet ernie would have hit 600 at 20 psi with just those 2 extra mods. 20 psi sounds like so much to us, but its really nothing compared to what other FI communities are running in their cars to get their big numbers... some of the Supra guys are running 30+ psi just to hit 700rwhp... given some of them make a TON more at the pressure... but honestly 20 psi is nothing special in a well tuned car.
With variable valve timing at hand here, we can work pretty far with stock camshafts.
In retrospect... cams and headwork will change everything. My car made 573 at 14.5 psi still on stock intake manifold and no where near finished tuning. My goal is 615rwhp at 14.5 psi after upgrading the intake manifold and fine tuning.

i got a set of nismo r-tune cams. it should help, plus going to do some pocket porting and knife edge the center divider. not really wanting to drop another $1500 or so to go oversized valves and such. this project is starting to get spendy already, lol.

Phunk, wasnt ernie's car doing that at higher elevation. I "thought" he posted mid 550whp numbers at sea level at 20psi. Anyways, if you look at the compression map, there is almost no more airflow available on the 18G compressor after 20psi. And its all about airflow, rather than PSI....as you know. 
All you'd be doing is generating more heat.
I'd rather see slightly lower pressure, but higher airflow.
Your car is an awesome setup, and thats why you got great numbers, at relatively low boost pressure. I guess that is my point. Doable with a stock head....but difficult...that's all I am saying.
If someone really wants 600whp, an upgrade to a 20G wheel would be my first step.
