you can get a good 400-450 bhp from bpu mods depending on how bpu you go as such, the strength of engine is awesome do some research on the 2jz gte great reading.

In terms of max bhp it will take it depends on many factors, high boost leads to high egt's with small turbos you could blow an engine up at 500bhp it's all in the tuning and supporting mods, if correctly set up with a good size turbo the engine can take 700bhp all day long if it's looked after and serviced well etc and some stock engines have taken 800-900 for long periods of time and some also upto 1000-1100bhp.

Since so few UK specs are around I'll assume you're going for a jspec. The mkiv.com site only caters for the "export" spec (US/UK/Euro), not jspec. For BPU on a jspec you need:

 

- Walbro

- 2x decat pipes

- 1.2 bar (max) Restrictor ring (without this it'll overboost)

- FCD (Thor only for jspec)

- FULL service including fuel filter

- Aftermarket Cat-back exhaust (the straighter the better)

 

Aftermarket air filter is NOT recommended - keep it stock. Boost controller is not needed either. You MUST have a decent IC otherwise top end power will be compromised.

 

The actual power you get varies a great deal between cars. If everything is running well 400bhp flywheel is expected, if you car is a good one 430bhp flywheel is max on stockers. I've not seen more than this on any trustworthy dyno.
