MT-no,i was referring to the stock motor that comes in all Supra's.It was/is built by ZF(Germany).Toyota got tired of Datsun(the Z) handing them their a$$.So they had to contract with the the Krauts to get a good(great piece).
THe HP numbers others have mentioned concerning the Supra are accurate.
I'm running about 20lbs of boost.It is harder to keep traction when the boost comes up with the Z then it was with my Cobra.
And it's blue with white stripes*.
And no-i didn't paint it that way.
