I quite enjoy trawling YouTube looking at the various kit car videos and I started to subscribe to MK recently. It's interesting to see the similarities and differences in engineering solutions between our Westfields and their Indy's.
Generally the Indy now seems to mostly run mx5 (n/a or turbo) or bike engines, but a few are running the S2000.
Next week they are doing a weight comparison on the F20 on standard gearbox with a K20 on a MX5 6spd (with new adapter plate) that some might find interesting. The mazda 'box is definitely a lot slimmer up to the bellhousing but I'm not sure how they are solving the height challenge with the K20...
At the end of this week's you can see the two boxes side by side.
