Thatās kinda what has me scratching my head. BMW hasnāt had an iron block since 2000ish and the engine plant (also in Steyr, Austria) isnāt setup to even make one. Itās tooled to make the modular B series engines, so if this is accurate:Interesting.
That ZF Guideline is very close to final BMW horsepower specifications, so it should be pretty close for the Supra too.
As for using a "regular" B58, that just makes a lot of sense for cost savings, although A70TTR has pointed in a different direction (BMW iron block with a Toyota modified head).
We keep waiting in semi-darkness I guess.
SZ - 4cyl
SZ-R - 6cyl, 3070lbs
RZ - 6 cyl 3350lbs
I could account for 270lbs of weight if it is an S55 or S58 with DCT (which is significantly heavier than the ZF Planetary 8 Speed). At the same time, if the SZ-R is the Z4 M40i equivalent, where did all the weight loss come from?
