Whats up guys?? I'm dropping a new (well... rebuilt...) engine into my 87 TII and I'm looking at all the potential engine manufacturers. So far I know of Hayes Engineering, Atkins Rotary, Mazdatrix and SAS. What other companies have good reputaions? After I find a company I want to go with, what upgrades would you suggest? I am considering 3mm apex seals and a street port.

Thanks

hayes is not good

atkins is good, pineapple is good, kd rotary is good, pettit is good, mazdatrix is good

 

What is it about Hayes that is not good? Anyone have bad experience with them? Good experience?

A good thread on why not to get a Hayes rebuild.
