For all you 3800 s/c experts out there. I am going to be swapping in a '97 3800 S/C into my 308 replica build and I need to buy a fuel rail and injectors for the motor. Didn't come with them. I found an '05 S/C L32 fuel rail on ebay motors but in looking around on the net, I can't determine if the '05 fuel rail will fit the '97 L67. Pretty sure the '05 had moved to the Series III from Series II so not sure if it will transfer over.

Also, I have put an ad asking for one in the Mall.

Thanks
Don

It will fit but not a direct fit and also you have to come up with a retunless system to run the newer rails. I will reply to you Ad in the Mall as I have what you need.....

Don, the L32 fuel rail will bolt right onto your engine. With a little modification (to the rail) it can be turned around on the engine so it faces the correct corner of the engine compartment to simplify fuel line routing.

Now, what you need to be aware of is the L32 fuel rail only has a supply line, is returnless, which means it doesn't have a fuel pressure regulator - which you are going to need.

I like using these L32 fuel rails in the swaps I do because they clean up the engine and simplify the fuel system that is on the top of the engine. But in order to use them, I custom build a remote fuel pressure regulator (from L67 fuel rail parts) and mount it down by the fuel filter.

Wow;

Fast replies. Thanks guys.

I have a couple PM's already as well for what I need and have replied. I am not too worried about the top of the engine really as the lines can be made to look pretty with paint etc. It is going into a Ferrari 308 replica so I might build a fake intake box that says Ferrari on it more like oem 308's.

If I do go the late model route, I will search the technical discussion area and find the thread on how to do it. I am sure it would be in there somewhere.....

Again, thanks for the replies.

Cheers
Don

I just made this webpage showing some pictures explaining some of the mods that need to be done to the rail...

Thanks very much for the info.

I just picked up a '97 setup off a member here so I am good to go on the fuel rail and injectors. Now, as I get into this, I am sure I will start uncovering all the other stuff I need......

Already have the flywheel on its way, have a SPEC II clutch already, have the mounts and lower alt bracket, 3800 harness..... Only about 2-3 dozen things will show up now......

Thanks all
Don

Just to give you a visual idea as to how the engine can look, here is a 3800 SC Series III engine (converted from drive by wire) installed in an 88 Mera. This should be very similar to the F308 rebody you are wanting. I can also show you a stock 3800 SC Series II engine with a 3.4 pulley in an 87 Mera if that is beneficial.

Thanks Nelson. The clean s/c looks nice. It does make a difference without the pipes running over the top for sure. This pic has nothing running over the top so I assume you removed the crossover pipes and refit them around the end of the s/c?

I have looked at a couple other SII pics that have the three pipes running across them and it doesn't look bad to me either. The look above is certainly nicer than the pipes though. I will see what I end up doing with the pipes once I get everything together. At least I have a fuel rail and injectors at a minimum though......

I appreciate the replies folks.

Don

The pics are of aftermarket FUEL RAILS not a stock series 3 fuel rail.

There will be 1 tube going over the top of the blower for the series 3 rails. Look on clubgp.com for good deals on the rails.

I would like to use one of these rails but can't find any. Does anyone know where to get them?
