Ziggy, not to sure about the loom, the throttle bodies belong to someone else. I did not receive a loom with them.

Chooie, sorry I don't release drawings. Been burnt a couple times before doing that with engine parts as well as in the architecture industry. No offense I am sure you are genuine but I just can't let them go.

As for a flange you are very welcome to buy one, do you need one as well for the SR20 primary manifold so it is a bolt-on bolt off fitting or are you welding directly to the SR20 manifold?

Flanges are in alloy, I hope this suits.

diymark, is this the case with alloy flanges as well? I wouldn't have thought so in this instance. I have found keeping the flanges bolted down and or tacked to some heavy plate reduces alot of the movement.
