cheers for the input chris. I used a disco potato on my old mx5 (GT2860RS)

what does the .76 bit mean, i don't understand turbos THAT well. a tutorial would be great

I won't be pushing the revs too high, 7-7500 will be pretty much it, engine wear becomes an issue much above that and my car will live in the top quarter of the rev range.

Megasquirt sounds like a winner, i've secretly been wanting to build one of those for quite a while.

Both side pods are currently used as rads, although the rear clam has room for big vents that face right into the wind flow, so i shall be putting my intercooler there
