pretty much brand new to this forum, and noticing a lot of intake plumbing discussion. I'm a car nerd, for sure. I've hacked and whacked with the worst of them. I've been obsessed at one time or another with turbo SAABs, turbo Volvos, & A1 Rabbit GTI's. we used to move our windshield washer nozzles to the turbo intercooler to squeeze (?)hp out of our shit. I guess the reason I've always wanted an M42 powered e30 was because things under the hood are pretty well sorted! factory individual coils, 16 valves, hydraulic lifters, 10:1 cr, forged internals, stainless exhaust header.. hell, my turbocharged SAABs only put out 150hp with a 2.0L & 16v heads and a LOT of extra weight!

I guess what I'm getting at here is we need to start thinking about 13:1 forged pistons and race gas.

basically its sumwhere in the area of 315 HP
of you could look into the DTM S14 setup for 372 hp?
either way just cam ITBs good chip larger injectors stiffer valve springs high compression pistons port and pollish full exhaust and a few other things and you will have a very strogn M42
or you can always boooooooost it!
