DOHC EFI modification underway
 

Made the big step tonight and cut straight through the middle of the EFI inlet manifold. I'm trying to mcguiver a plenum EFI up so that it will sit same height as the engine or even lower. First step it to get the inlet riser milled flat, 80mm from the base of the manifold

Could have completly balls'd my engine up but what the heck nothing ventured, nothing gained, I'll post up some pics of progress on Monday
Rapid:o

I know that people have modified the Pinto EFI and that some have made simple plenums for the Zetec soooo you should OK, you may loose a little flow but will gain it back with a K&N and a cold air feed.

Hi Rapid,
I'm gonna follow you're modifications, i've got an effi too. :D
Good luck !

That's what I did, I know its on a Pinto but the theory is the same. Been on the road 5 years with 18k on the clock

I did an extensive 'how to' pdf on how to do it but its too big to upload on this forum

Hi Mister Trophy !
Maybe you can post a link were we can download the "how to do" pdf ?
Sounds very interesting i :D

Sorry for the lack of progress folks, new job and holidays etc.

I've now finished cutting the manifold, managed to line the riser up best I could then tried to get someone to TIG it up for me... tried quite a few places but they refused as they didn't want the responsibility of screwing it up, even though I said just go for it?!?

In the end I got introduced to Chemical Metal, this stuff is awesome. You can buy it from alfhords for a reasonable 11.99 for 900g. I was sceptical at first but a mate has used it on a rstor he had done a few years ago and it's still holding strong.

I bonded the 2 half together and now am in the process of just filing it back to look like a sensible shape. I'll then finish it with plasticote black wrinkle finish.

I've bolted it up to the engine and fired her up without any trouble and sounded fine. All in all I think I've taken about 40mm out of the height
