I just had a very stout trans built by Jim at Der Transaxle. The car went faster and and works perfect in a street car. He rocks!!

How do you plan to drive it? I've run stock for years, but I don't beat on it off the line (only a dozen 1/4 mile passes and a dozen autocrosses with a 2110)

Don't forget Rancho Performance Transaxles as well - they have built A LOT of 'boxes for Forum members and actually step up and support the site as well. Click on their ad above for more details.

Rancho, see Mike H., Harold C. @ Rancho did mine, but when he had his own business way back. 202HP, no problem. I use it street and strip. Still going.

Jim at DerTransaxle built mine about 6yrs ago for my turbo'd 1914.  About 4yrs ago I started using it in my turbo'd 2276 with no issues- give him a call.

I do know some people that uses Jim's trannies also, with no problems.

I think all are super but I also say that the parts used and the way you drive will tell you a lot. Even the best builders will get broken trans with junk parts inside so plan on spending some bucks for good stuff to put inside your trans.
