high boost on stock engine???

[drew16]

i dont have a mr2 yet, but soon, but when i get it i want to get it to put out as much boost as possible(20-25psi) without rebuilding my entire motor. can this be done, if so how?

Why in the world would you want to boost 25psi is the real question? Your stock turbo will blow hot air after 15psi.... and do absolutely nothing for performance. To get rid of that... you will have to upgrade your turbo.... on an upgraded turbo.... a lot less boost will give you much more power than the stock ct26. You need to do some research my friend.

hey Russell, r u running 18psi now w/ur CT27?

i was planing on upgrading the turbo, like a t3 or something that will work without uggrading the motor.

[MR2Jedi]

the stock internals of the 3sgte are pretty strong..T3 is a popular upgrade for the MR2 T. u will have to upgrade fuel system and Intercooler for the added boost to be handled safely and keep detonation in check

MUHAHAHAHAAH..... yea.

[MRQtwinturbo]

sure u can run high boost on the stock motor....just have the proper supporting mods to keep the motor from blowing itself up....its all in the tuning....

[drew16]

ok thanx for the help...im planning on getting hks cams and upgrading the valves before getting a bigger turbo....along with new manifold and downpipe and bov

I was racing last year at 23.5 ~ 24.5 psi of boost on a 200,000 mile unopened stock engine.

With a correct set up, proper tuning and appropriate fuels, a lot is possible.
