This is the way I worked it out... seems to match the layout of the wires and the firing order is the same as a 1UZ. Yeah... post locations get a...

plug locations (firing order) shows that rotation is clockwise, and that the distributor is like having dual 4 cyl distributors firing on...

This gets interesting :) Each bank gets two plugs fired by the inner ring and two by the outer ring. What is the firing order ? OK, figured it...

Assuming that this is the distributor that you have.... ... it should not be too difficult to get it running with any reasonably capable ...

I have (from the days tuning Surreptious) a DIY Autotune IAC block that we tried to use on my smallport - it ended up not working because it was far...

As the air velocity is low inside the intake plenum at idle, and the vacuum is strong, it really doesn't matter all that much where the idle air is...

This throttle body does not have an idle circuit built in, and the throttle lever is set and there is no adjustment*. As far as an ECU, nothing as...

It is not always necessary to have all the idle air passing thru a single opening. For example, the E92 4AGE uses the idle air bypass screw to ...

EGR is 11mm diameter... Cold start injector hole is 15mm(19/32).....

Nice work, but I think that passage may be a bit small for idle air control... You'd normally want 1/2" min or better yet 5/8"

installed a roll pin so that I could set the T/B on to the 5V manifold. Once pinned, I scribed the new opening, and opened it from 65mm, to 70mm/ ...
