Fiat engine to reliant box

Postby Andreas » Mon Feb 28, 2011 10:38 pm

Hello,

can You please help me in finding an adaptor plate and possibly some advice how to fit a Fiat fire engine to a reliant gearbox.
Well at the moment my knowledge in these cars is very limited to be honest ( newby).

With best regards

What angle do you wish to mount the engine to the gear box? Mine was at 35 degrees

Hello Drutt,

thank You for answering, its a good question but to be honest not that easy to tell You.
Are the 35 Deg a common arrangement for oil pick up and the like and what about legroom i.e. pedal box width?

With best regards

Standard fiat is 11-12 degrees.ax knows exactly. Oil pick up was fine with the sump I made. Some people run 45 degrees ok. The pick up depends on how well you make the sump. The problem
I see is oil drain back too the sump but mine seemed ok.
As for leg room mine was mid engined so I wouldn't know!

Hello
What is the best clutch cover and release bearing to use when mating reliant gearbox to Fire engine please? I presume one uses the 1098 sprite driven plate.
Regards
John.

Most people use a standard Fiat clutch cover and a roller release bearing. You can either create one by modifying a Reliant carbon release bearing carrier or buy one from Peter May Engineering if you’re feeling lazy!

Yes you are right about the 1098cc Sprite plate. Driven plates for the other engine sizes won't fit the FIAT clutch cover.

If you use standard parts they should be OK, but I treat it gently and don't do a practice start on the warm up lap because the clutch can still be quite hot for the proper start and could slip a bit on the opening lap.
