930 fuel distributor

Does anyone have a good 930 fuel distributor for sale or can rebuild one. I am looking for something to increase performance with some mild mods: K27 turbo, sc cams, tuning, etc... is there a difference between the euro and usa fuel distributor?
Thanks...

I carry these and have a few in stock. Also handle rebuilds/modifications and match fuel heads with WUR's as a set tuned to your engine. The WUR's are rebuilt and modified as well.
Yes, the early "Euro" is steel and the '86-on is aluminum.
With mild mods you should not need to change your fuel head. You may need to change your WUR. The WUR can be rebuilt stock, made adjustable, or rebuilt to your engine's spec.
The AFR of your engine should be measured now to see the condition of your system and anticipate what, if anything, will be needed. Once the mods are in place re-measure the AFRs and make any adjustments.
Generally it is a good idea to assess the health of your fuel system before doing any mods. There are a lot a aging systems out there that are gummed up to some degree, or worn and out of spec.

With no modifications or adjustments done to the fuel heads the euro cast iron and USA '76-'79 fuel head that is always painted black flows 10% more fuel up top under boost than a 1986-89 cast aluminum silver colored USA lambda fuel head.

I have this one. I sent you an email through pelican.

There is probably another 10% fuel by lowering control pressure via the WUR and a bit more by bumping the system pressure via shiming the regulator at the head's exit.

Also see CISFLOWTECH for rebuilding and modification of Fuel Distributor's & WUR's. Larry is a great guy to and builds the high flow FD's if you are going for over about 400chp.

Having a fresh FD with injectors tested for ballance is good insurance having a cylinder run lean.

Fuel distributor modifications are not needed to support those mods.
You should look at tuning the WUR for more power, better fuel mileage, etc.

I would think it might depend on what he means by mild mods, K27 and etc ?

Also if it is going to see track duty?
