Re: [DML] Re: DeLorean Transmission Gears

[Martin Gutkowski <webmaster@xxxx>]

That is correct. The only difference between the 369 (DeLorean/Ren30) 
gearbox and the UN1 from the Ren25/Esprit is the latter is a cable 
shift. Internally they're identical but with alternatives available for 
gearing. The Ren20 used a 4.1:1 on the final drive if anyone wants a 
drag DeLorean. Unfortunately not many 30's were made as manuals (with 
3.8:1) and we all know the Esprit went out of production due to Renault 
stopping making the gearbox components - good luck finding a 3.88:1 
final drive gear and mainshaft

The DeLorean's final drive is 3.44 to 1 while the Lotus is 3.88 to 1. The Lotus appears to have slightly lower gearing where it counts so I'd say by looking atthis, all you have to do is swap the ring gear to the other side of the pinion. The final drive gear ratio looks like it would offer a bit more performance with a very slight sacrifice in economy. The only other difference is 4th gear being slightly lower in the Lotus but that 3.88 final drive is definitely going to make the car a bit more responsive. If after running with the lower final drive you think lowering the gearing a bit more may even be better you may consider going to a smaller diameter rear tire, say 245/50/15. This would lower things in a similar fashion across the entire range of transmission gears.
