So, with two perfect gaskets, I bolted the DBW throttle body up to the N42 manifold. I’m short a stud. I know most of you would have seen that and just let it go, but @Yarb is a brutal task master and he would have given me hell for not fessing up…

Need a little help from my obsessively cataloging Z brethren. I am likely going with an iBooster so I will not be pulling vacuum from the intake manifold. Has anyone cataloged the hole sizes? I need to source aluminum plugs.

Also, I drew up a blanking plate for the cold start injector port. But, I recall someone has already made one. Godzilla?

Good! Because I just looked at the Godzilla blanking plate and there ain’t no way!

So, down the road, after I’ve gotten things running the way I’d like, I’m thinking of going to ITB’s. But, I’m committed to DBW. I removed the pivot for linkage from the firewall so I’m all in. When I go to ITB’s, how do I control three throttles?

I see a cable linkage that pulls down at the left arrow. And the front two ITBs are connected to the middle two ITBs at the right arrow.

And there is a list of options on their site.

I'm not familiar enough with the Jenvey setup to explain the first two options. The third looks like a throttle-by-wire setup.

I just found another picture that may show the double linkage.

Update on the 4 post lift. It will be delivered Thursday the 15th. It will take a while to erect as my help went back to New York on the third, but… it will be here.
