fuel rail options

[bluedevils]

I know stock 318i rail can be made to work with tii or early 320 EFi manifold and runners for MS conversion, but I want to use a better unit that will fit like a glove, and possibly made of billet alloy. Any tips or suggestions? I have seen links at top end web site but not sure they will work under tii runners. TIA

buy a glove.

Seriously, there are not many engines with the 100mm bore spacing of the M10,

and the rails on them look even worse than the 320.

You can pay a lot to have something milled up out of aluminum stock,

but it's not going to work any better than the 320 part.

All that said, if you're hell- bent on spending the money, any aftermarket

EFI supplier (like TWM) will have the extrusions and can mill

the seats for the injectors. I suppose you could do it yourself

if you were good with a drill press.

What do you mean by Tii runners? Do you intend on using the entire intake manifold?

I'd say mine fits like a glove...

also look at extrudabody

I'm afraid you will have hard time fitting a billet one in there. The oem sheetmetal pipe is thinner walled than alu can ever be. I don't think you can beat ///MChris's very nice installation with anything more custom.

Also, the fuel rail attaches to the injectors at an angle. It would be near impossible to match that angle without a precise machine shop.

...or a vice for your drill press that can do angles...

Ok, thanks. I am looking for a solution without welding those tabs. I guess I need to make some brackets to hold the rail in place.

Use one side off a mustang they use 100mm spacing they make high flow ones.

100 mm spacing.....but are they Angled?

Al, just pick up some aluminum round stock at any online metal site and take the pieces to a weld shop with the fuel rail and the lower portion of the intake. It shouldn't be more than $30 to have them weld the stand-offs to the intake. Easy peasy.

Al I have been thinking about making a few rails. Is it something you need asap or do you have a little time?

No hurry. I have the 318i set up already running, want to change it to tii/320 style intake as the car is originally a tii, eventually to be used with a modern EFI control unit instead of Bosch Jetronic (which works surprisingly well with a tii engine and distributor).
