heads for 11.5:1 compression ratio
ok, i am planning to get a forged 11.5:1 piston, valve spring, Ti retainer, forged rods, some 268/272 cams, header and heads.
but i couldn't decide which header and heads to go with this setup ?(and did i missed anything on the list?)
o, and i am currently runing Amuse test pipe, Ti y-pipe and Ti exhyaust + a popcharger. going to reflash my ecu soon
some comments will be appreciate

You can use VQ30 heads and save your money of forged pistons. That will raise the compression with out $1000 pistons. Get them port and polished and maybe invest some of that money on oversized stainless steel valves.

$3000 for the 46cc heads w/ all parts needed for the install...
can be used with the NISMO or JWT cams or any cams that will work with the stock heads...
it comes with the VK45 Titanium Valves, High Lift Valve Springs, Retainers, Spring Seats...

Also, with just this setup. It would raise compression. So would you have to switch out pistons? Can this be combined with a stroker kit?

Haha, you probally get 25 whp at the most and maybe 10-15 more is you spend another $1000 on cams.
I say spend 200 dollars on VQ30 Heads, and $1000 on cams, 500 on springs and retainers and 500 for port and polish.
Total for those items are $2200, and you should gain 30-35 whp.

A ecu reflash would help with all this, a richer fuel program to help with detonation from the high compression, an extended redline would even increase the power from the cams and port and polish. The high compression, port and polish, cams, and ecu should be about 50 whp.
