Manifold conversions.

[Mark Pitts]

Chris,
	When fitting injectors, the collars need to be trimmed inside so that =
its all flush (wouldn't want anything lowering the VE by putting a lump =
in the flow now would we?)
 You aint going to believe this but, on a semi permanent basis, you can =
epoxy (slow epoxy, overnight stuff) the adapters into the recesses of =
the manifold! No the heat doesn't do too much damage. Works fine. =
And.... Here is the good bit, point a blow torch down the hole in the =
middle for a few seconds (till the epoxy smokes... dont breath the =
fumes, they are harmful... and mores the point they STINK) and you will =
find the epoxy has gone soft, and you can twist the injector seat back =
out of the head.

Dont try this trick with your EGOs guys.... The epoxy might just not =
hold in that application!

(You can do it with body filler as well! (Isopon, plastic padding etc))

Does anyone have any experience in modifying manifolds to take EFI
injectors?

I wonder if anyone tell me if there is any source in the UK for adaptors
to weld into a carb type manifold so that EFI injectors can be fitted.
I do have the dimensions from Weber Alpha, so I could have some machined
up and TIG welded into the manifold, but it would be less hassle to be
able to buy them ready made.
I know that such things are available in the US, having seen them in the
book by Jeff Hartman.

The manifold I want to modify isn't a carb one, but the one that is
normally used with the Bosch mechanical injection (K-jetronic) on the
Renault V6.  (on this version of the engine, the mechanical injectors
are in the head, not the manifold as on the EFI versions of the engine.)
The manifold has two plenum chambers and cross-over inlet runners.  I am
informed that the flow on this is much better than on the normal
Renault/Volvo/Peugot EFI manifold.  (I would use two throttle bodies,
one at the end of each plenum chamber.  It's to convert an Alpine-
Renault GTA to fuel injection).

I know where the injectors should be fitted on the manifold, it's just
the adapter bits I need.

Thanks for any advice,
