I'm trying to find out which is larger and flows better...

2.0 DJET intake manifold and plenum (diameter?)

or

1.8 LJET intake manifold and plenum (diameter?)

I gotta find some aluminum, copper or PVC tubing that is the proper diameter for either, and some rubber grommets to use as connectors. If I had a 2.0 intake manifold I could do comparison but I can't... If you can provide info please do help

Thanks!

As far as the throttle bodies go, I believe they are all the same size on the backside. I will measure them tomorrow and post the dimensions.

Djet 2.0l is 36mm
Ljet 1.8l is smaller IIRC and stepped to take the bigger intake to plenum gaskets?

According to Jake the best is
2.0L runners
2.0L bus plenum as the sidedraft TB flows better

Thanks guys! I'll wait for some more measurements to pop up. I might be stuck with the 1.8 intake and plenum until I locate a bus manifold.
