So I hear all this praise everywhere I look about how great the 3s-gte is. And I don't doubt it one bit but I was just wondering how much boost the engine can handle and what kind of turbo it comes equipped with. Also, what would be an estimated HP after approximately $3000 in mods (let's say 15lbs of boost).

will you be doing the work yourself or having it done. if your having it done at a shop then $3000 wont go very far. if i were you, i'de start from the inside out. start with forged internal, then work on the valvetrain. after that the sky's the limit.

here is a great list of upgrades:

I would go for a turbo upgrade, clutch upgrade and exhaust

don't forget if you go big on power, the GT axels may not hold up

the JUN stroker kit is approx 5200 not including shipping from japan.
