Very cool and it looks fantastic, nice to see some updated pics

Thanks! Here is another pic I found

I've got a decent tune on it right now that will run and drive the car quite well, and runs up to about 11psi. The timing isn't optimum (conservative and not very smooth) but I'm waiting for dyno time to really dial it in. The motor should be fairly reliable up to about 18 psi, but for mainly street driving (some auto-cross and some drag strip) I think 15-16psi with careful tuning it should be plenty fast enough .

I'd be worried about the tranny at 18psi, hell even Jack's killed a few with light boost Are you using Albins/Weddle gears?

1,2 gears are stock, 3,4 are coarse tooth bus gears (late splined 3-4 shift hub that uses factory 002 gears). These gears have the syncro hub welded to the gear from the factory.

Ratios are 3.78, 2.06, 1.26, .82

944 CV's

The tranny is the late 'zig-zag' case with the extra ribs on the top. I won't be running slicks on it, and if I do they will be small (7") so I'm not too worried about gears breaking.

Tranny life will depend on traction (shockload) and sometimes moreso the guy behind the wheel. I'm not one to dump the clutch or anything so I'm confident it will stay together. We'll find out!!

I just remembered theres a guy on the samba with a +400hp turbo'd honda motor and last I checked his trans was still alive.
