Intake setup? 1800


Phil et al., what difference do you think DCOE style throttlebodies would have on your average FI B20? I'm thinking specifically of what difference they would make vs. a Djet manifold with the big shared plenum. I was under the impression that this stock design was OK for a street engine and that ITB's or DCOE throttlebodies would not give much improvement except for high-rpm running.

I'm rethinking that!

These guys have some DCOE type TB's in all sizes.

Looks like you can get something suitable in the $450-$600 USD range. Using stock port injection (fuel rail, injectors) controlled by megasquirt or SDS it would be relatively economical for someone moving to aftermarket injection to experiment.
