Hod do I get more BHP from my Supra Turbo?

[the_fallen]

metal head gaskets are a waste on a street 7m supra. you can easily run 350hp from a t04'd ct26, lexus reimer upgrade, and a front mount, exhaust and filter all on a stock head gasket. it's not the gasket that is the problem. it's poor torque settings from factory. if you do the head gasket, get both the block and head skimmed to be true, arp bolts to the better settings (i don't know exactly what that is, but suprragirl does) and stock head gasket, do the above upgrades, and your on your way. for a street supra, thats nothing to laugh at.

to answer your questions:

How much psi boot will it have as standard?
usually about 6-7psi on a 7m-gte

How much psi can I go upto reasonably safely?
once HG is sorted, 10-11 is fine

How easy is it to make the turbo boost more psi? is there an newbies guide anywhere?
difficult to explain, but get a boost tap put into your boost control solenoid pipe from the turbo compressor housing, and away you go

Any Ideas how much BHP I could expect?
probably 30hp from 6psi to 10-11

hope that helps
