Fitting a 1098 to a Series II

Post by **adritch** » Thu Jul 19, 2007 1:43 pm

Just bought me a 1098 engine and box. Will this slip straight in in place of my 803, or will I need a 1098 prop shaft too?

And should I replace the diff? Thinking that an 803 diff with a 1098 may not be a great mix. Drivingwise I'm after reasonable trade off of acceleration/top speed, suitable for everyday driving.

Thanks for any advice.
Adam.

I imagine keeping the 803 diff would give you very low top speed, getting the 1098 diff would be best. I dont know about the propshaft, main problem you will have is the gearlever. the 1098 gearlever will want to enter the car much further back than the current hole in the floor for the 803 gearlever. you will need to cut an extra hole, I think it is possible to convert the 1098 gearbox to have the gearlever in the original place.

The remote assembly can be removed i think, but you'll end up with a pudding stirrer of a gearbox!

1098 gearbox will require the floor to be hacked about - and the later floor section over the gearbox remote fitted. 803 diff will be very low geared for any series motoring.
