V8 efi question...

(1/3) > >>

V8MoneyPit:
Can I fit a 3.5 or 3.9 efi into my 110 using the carbs from the existing 3.5 V8? Am I likely to need different metering needles?

Any other problems that I might encounter fitting a later engine into the '83 LR?

Any advice greatly appreciated.

Range Rover Blues:
Yes

I don't know what will happen with your needles though, It will want tuning.

The big difference with the EFi lump is the heads are slightly better, the combustion chamber is different and the valves are bigger.  Also the exhaust manifolds are much better but I think the driver's side one will not fit if memeory serves correctly.  The 3.9 also had a much better cam than the 3.5 and this accounts for the extra HP that the 3.9 had.

If you fit a 3.5 you can still add the 3.9 cam.

V8MoneyPit:
Thanks. That's useful to know.

The exhaust manifold problem isn't an issue since I'm going to fit tubular ones anyway.

I appreciate the needle issue and assumed it would need dealing with. I go through this on a daily basis with kids who throw a K&N filter on their Mini and wonder why it goes all asthmatic on them at 50mph!

Range Rover Blues:
Why not fit the EFi?

V8MoneyPit:
Is it not ECU driven? I don't want to get into all that. Want to keep it as simple as possible so I can fix it with a big hammer  :lol:
