Q I decided to get a Datsun 240Z and I am looking into the RB26DETT swap. I would like to bolt a 350Z transmission to it but I can't find out if it will fit or if I'd need a custom bell housing. If you have any advice I would appreciate it. LanceVia the Internet
A The RB26DETT swap is an ambitious one indeed. We will say that the RB block will not bolt up to a Z33 gearbox without modification to the bell housing. This is the case for all RB series engine blocks, and that means even the RB20. The RB20 and its little KA-style gearbox line up pretty nice though. We saw Ernie Fixmer do a RB20DET swap into an S30 Z car, so don't think this is a heap swap and make sure you have at least 30-percent more saved than your initial budget because you'll probably end up spending $10K plus to get it all done right-and that is only a rough idea of what it would cost to use a RB25DET engine set up. If this is still something you want to tackle, we'd also recommend buying brakes to go with your swap; seriously! Buy some good brakes. Make sure you can get the suspension upgraded as well, because 300hp Z cars are scary as hell when you have 35-year-old brakes and suspension! Check out Motorsport Auto in Orange, CA (www.motorsportauto.com); they have a ton of awesome stuff for the Z car. Good luck and send us some pics of your project as it moves along.
