Title: Firewall mods for webers/EFI
Post by: uppo44 on March 07, 2010, 08:36:47 PM
Hi
I have been building a new motor for my HB Torana but now i'm eyeing off the FC for a transplant.
My new motor has a J-Zed alloy head with EFI on a triple weber manifold. The throttle bodies are similar to webers 52mm. I have been looking all over this site trying to get a good picture or description of the firewall mods required. Any help would be greatly appreciated.

Thanks in advance

Paul

Paul don't think anyone runs a Jz head on an FE FC  ???well not yet at least  ::) the location of the manifolds on one of Joe's heads is different from a 9 or 12 port Holden head that some members  run with Webers ...I know that the head with Webers will fit in an EH engine bay with only a little modifying  to the firewall as Joe's cousin had a head and Webers on his EH  think you may have to fit it up to see exactly what is required ...I am sure someone will have a shot of the engine bay with a set of Webers  as a starting point ........FC427.......

i have just installed tripple dellortos on my red motor powered FE i had previoslly recessed thr fire wall 40 mm to fit tripple SUs 1 3/4. The dellortos fitted no problem but my manifold is a Lynx manifold with the outer two carburettors offset toward the centre of the motor. some Weber /Dellorto manifolds sit the caburettors centre of there inlet ports which would cause the rear carburettor to sit further to the rear of the motor requiring greater set back of the firewall around the rear carb and linkages
                    hope this helps Simon Addison

Cheers

sorry i am a computer spastic photos are a little bit hard for me at the moment . but if your coming to the nationals your welcome to take some yourself. with a red motor sitting in the engine bay it really is a very easy job to measure the required recess you need to cut and weld . meanwhile ill try and work on my computer skills and see if i cant work how to upload photos
                        all the best Simon Addison
