Once getting the car I tried to make a plan.. It started out as a hot m10 with cam twin 45s etc... I then got offered an m42 for good money and thought seen as it would make the same power as putting that work into an m10 why not.
And as always I decided that wouldn't be enough. I started getting together parts to supercharge the m42. I built an intake plenum and was about to start on a mount when I had a serious think about what I was doing..
Two things came from this
1. iATs would be sky high pushing an eaton m62
2. I would need to make a custom header due to the steering box behind subframe (rack in front on e30)
That's when the real fun started. I just picked up my holset HY35 with a small exhaust side for quick spool!
