Re: cams for 50 trim
 

I just noticed you have a 90' GS-T, so even 91' GSX / GS-T cams would be an improvement let alone the HKS 272's!

IMHO, HKS 272 cams > all other 272 cams.

Word.

Re: cams for 50 trim
 

Yeah, and drivability is somewhat of a priority too, and since I'm not planning on doing and valvetrain work just yet, 7500-8000rpm is about all the higher I want to go, if a 50 will even be making peak power out there... my car seems like it starts falling off around 6500rpm now, I think with some flow issues fixed and cams that should be closer to 7000rpm?

Re: cams for 50 trim
 

You shouldn't have to worry about drive ability issues from 272 cams, many daily drive their DSM on them. If you wanted to be a little more conservative and 'street' able you could consider 264 intake / 272 exhaust cams which is my personal favorite combo.

Are you still stuck on the stock intake manifold? That will be a big restriction in the higher RPMs on high boost along with a stock throttle body elbow...

Re: cams for 50 trim
 

HKS 272's or FP4R's.

One thing to consider, 30 psi on a .50 trim is pretty much maxed out, especially as the rpm goes higher. So although you will see an improvement, you may want to consider upping the turbo in the near future.

Re: cams for 50 trim
 

Yeah, I knew that would be about all that turbo would do as far as boost, just thinking making more efficient use of it may help... of course one might think more traction would be the most efficient use, But I have given up on that till the AWD swap.
