hi no there is no reason why I chose 735 set up. but I think that this is the kit that the engine has best of since a 745 suit approximately 250 horses.
Why do you think that it is must to install but must intercooler.! what systems are best for a M30 b35engine, I thought if having to install turbo would be best if i had some forging pistons .
I do not want my car to a super fast car, but it may well move
How much horsepower can a B35 engine endure without it crashes all the time.
As you know there are no speed limit in germany:mrgreen:
Others have taken the stock B35 up to the mid 300s, but then they start running into gasket/stud issues. Many M30s are in the low 400s with a better head gasket and some ARP studs, but stock pistons and stock rods.
The crucial factor with the longevity of a turbo system is the tune. A proper tune will make or destroy a turbo system in short order. To that end, I do not like the 745 system's air metering device, the AFM. I generally prefer a MAP or MAF, due to the better transient response of those devices. (to say nothing of general accuracy) If you wanted to leave it at the stock levels for everything, then the stock 745 AFM would likely be fine. However, if you are going to bump it up a bit, then the AFM can and often does cause issues.
Todd at TCD has (last I looked, anyway) gotten around this using a Rising-Rate Fuel Pressure Regulator (RRFPR) and a tune to re-scale the fuel/spark table. Miller replaces the AFM with a MAF and has a custom tune. One thing I really like about the Miller system is they include a user-configurable chip, so you can change the tune yourself if you decide to change things up a bit later. The TCD kit is more proven, though.
