BPT tranny HP capability?Engine Difference
 

How much HP can the GTX BPT tranny handle?How much HP can the GTR BPT tranny handle?Whats the difference between the GTX engine and the GTR engine?Just bigger turbo?

Thanks,
Elliot

Bigger turbo, beefed up internals, slightly lower compression + maybe a few more things.

same tranny (4WD btw)

Stock:
GTX = 180HP
GTR = 210HP

2WD (G25M-R) tranny should only hold a max of 300HP- ft/lbs... not certain on this though.
