Hehe! Thanks Wally, But I must admit that I only made the plenum sheets holding it in place with tape! And had a friend of mine welding it together,

The injectors are Bosch no. 208 150 447 which give 241cc. High imp. (12 ohms) With cut and welded Audi fuel rails, together with a 944 fuel pump it becomes a nice set up!

Be carefulll with a turbo on a 2,1 ltr engine and 241cc injectors. They seem a little small sized for that. Forget where they came from or what the books say.
You don't want to lean out with a turbo...

Good luck,
Walter

Ahh, no I’m going to run it as a normal aspirated engine.. Not a turbo. Ported heads with 10.5:1 comp.
And W120 cam with Type-1 lifters.. So I think I am on the safe side!

I see, yes, then I agree (boring but I do).

But why then not keep the stock plenum?

Greetings,
Walter

Two reasons, first the old plenum will only accept the wbx trottelbody, which it’s only 46mm and the A4 is 60mm…. In addition, I have made velocity stacks inside, where the stock just has four straight pipes going in, and it look cool!!

Ok I was checkin out the megasquirt site. Can anybody really build it and tune it? Im pretty electronically challenged so I was just seeing how hard it was for the guys that did it.

It was pretty easy. You have to be able to solder, but thats easy with a little practice. Just make sure you have the instructions and have read them through a few times before you start.. Test as you go. The docs are pretty good for building it..
