I spent a lot of time considering the available main and rod bearings available for the modular engine and in the end I decided to go with Clevite. Shown above are the bearings I ordered right after I took them out of the box.
I ordered the bearings in the standard sizing because I'm the original owner of my 2001 Teksid Cobra and since I've maintained the engine, I'm assuming that I should be OK with using standard sizing.
One of the reasons I decided to go with Clevite Mahle is that Mahle is a global leader in powertrain components and is a tier one automotive supplier. Furthermore, I was able to consult directly with Mahle on selecting bearings for my engine so that further solidified my reasoning to use Clevite bearings.
Male is extensively involved in Formula one as a partner with the Ferrari F1 team so I have no doubts that the Mahle Levite bearings I will use in my Tekisid build will be of the highest quality.
I believe that most people here use another brand of bearings and have done so with success. However, I have already chosen many parts for my engine build that go against what is commonly used with bearings being one of them.
