Get an M30 first... then a turbo!!
The time has come to decide on which turbo to go with for my E34 (M20)....
I've decided a T3 flange size, air-cooled, and been quoted on a garrett turbo (AUD$1400)
Does anyone know what KKR turbo's are like? Seen similar specs to the garrett i was quoted going for AUD$800...

whats wrong with an M20 turbo?Originally Posted by pundit
C'mon guys.... Don;t be so nally. M20s are good engines, just smaller. Ideal cadidates for turbos too, and they are more efficient than their bigger, older cousins... Luke, KKK are good turbos, the factory setups are hard to beat if you have reliability and longevity in mind rather than stunningly bright performance for a short time... I'd go with a factory setup if I did it, but it is easier to play perhaps with an M20. NickOriginally Posted by BigKriss

Sorry to go a bit off topic, but why are nearly all of the turboed e34s that are documented online m30s? Luke may want to know. I dont think i have ever read about a 530i or 540i. Perhaps this is because the m30 is so over engineered in the first place that it can withstand boost pressures at which other engines would blow apart?

i've seen a few supercharged 540's around, there was a guy named JimmyZ that had a black/black one. he got banned from bf.c though or something. last i saw of his car was on the eurowerkz california site

There's a guy andrew (i think) on here with a turbo M30 pushing 350+ rwhp with 220k miles on a completely factory motor. How many other engines do you know that can handle that?

I agree, the M20 is a good little engine to turbo. I have had alot of fun with mine.

PS what the hell is an aircooled turbo?
BigKriss - A T3 is perfect size for any 2.5L engine. We run a T3/T04E on a 3.0L engine and its actually too small for what we want to do.
