hey guys, im from australia, and wanted to get some info off you guys over there where u invest heaps of money and time into your engines / builds etc!

i Curently have a 2005 Ls1

Manley pushrods
918 comps
tit retainers
ls6 manifold
standard Flybywire TB ( i think 78mm )
224/228 custom turbo cam
gt35r turbo
intercooled
custom 4" magnaflow exaust ( off a 3"dump pipe )
42pound injectors
1/2inch fuel lines
twin bosch 044 fuel pumps
and a few other things but cant think off top of head..

runs 500rwhp on 12psi

im wanting to do my bottom end / heads / manifold etc

forged pistons / rods / arp the whole lot etc... my question is...

for best " bang for buck " from guys with the experience whats the best thing to do? rebuild my bottom end and put new heads / manifold / TB ( do i really need to change manifold? or can i port it +add a 90mmLS2 TB )

what heads? aftermarket ? or port my ones ? or get ls2 l92 l76 etc? ported etc for best performance under boost?

better to get a stroker kit, or just rebuild bottom end? what have other guys gotten out of there ls1 turbos etc?

i know its alot of questions... but the guys here really talk crap and just want to make u spend all this money on **** all!!
