make sure you read up on M20 ITBs before taking the plunge though! Racehead / RHD is probably a better choice all things considered.

e30.de inspiration

So... it turns out this e30.de car also has a dbilas setup. Don't know anything about the CF plenum unfortunately, but the brake booster is in the standard location.



There's no question that the standard dbilas plenum is small, and the ITBs themselves too big for a standard motor. low end torque is better over a single TB, but midrange torque drops - period. the standard intake has much longer intake runners and performs better. that's why fporro and this guy have spent effort replacing the plenum.

It's also why i really dig whodwho's SC setup. if I can combine a vortech sc with the dbilas plenum, stroke and cam I get all I want. Basically merge these two photos:



it's not about dropping a race motor in my car. I could stroke a bottom end and drop some RHD ITBs in if I wanted that.

The RHDs outperform the dbilas I'm certain of it. But I think you'd have a hard time adding a plenum and SC to an RHD engine. Can't wait to see what whodwho comes up with there!

Waking back up..

Car's been cocooned all winter as usual, though did get a chance this past weekend to get it out there


I'm heading to AtTheVintage in May and will have the vert euro valance work finished by then. Also getting the hardtop headliner repaired and installing the $&^% expensive hardtop seal.

On the dbilas.... finally gonna get the ball rolling on installing it, but don't think I'll have time to install and tune with stock ECU, so I'll plan on doing that in June. Was thinking about a dbilas chip but since I'm definitely gonna SC that seems like a waste of $$.

I also just swapped messages with whodwho... He's running RHD ITBs on an M20 and is now looking into an SC setup... so game is finally on for ITBs on this end... hopefully I can learn from the best here.

MS+dbilas+SC here we come!

Vert looks great bud!! Saw it earlier this year at the Montrose Harbor meet. I was in the black 86 325e.
