Well right, by the time you do the head, intake, exhaust etc etc you are looking at closer to 10k probably ... but at least this way I can do it in steps and the start with the $5k conversion to 2.5L right?

Was Turner's price $2+k for the kit and a TOTAL of $5 if they install, or an additional $5k to install? If the TOTAL was just $5k then that is a very very good price.

When I talked to ERT about how to start I was looking at two options: 2.5L or supercharger. The claims on supercharges are 90(+) hp but I didn't see that much on the Dinan supercharger that was put on my E36 car (more like 60hp). Even ERT (who is noted as one of the few E30M3 supercharger suppliers) recommended the 2.5L approach as a more 'stable' setup. I too have seen claims of 285hp out of a 2.5L motor, but the 'standard' I think (with normal head porting, polishing, and 'streetable' cam changes) is about 235-240hp. [According to Korman, with a properly set up suspension, this is still enough to beat stock US E36M3s on the track due to power-to-weight ratio.]
