*disclaimer I have zero personal experience with the Cobb tuner*

That being said I also have no experience with rotary engines or how reliable/well they hold up to higher than factory HP.

My DSM smog test is due this October lol...it will be fun with all my recent mods including EVO 3 IM.
My miss understanding on the mileage of your 4B11T, it appears you are re-using 49k motor instead of rebuilding your own with 230k, is this correct?

Regarding rotary engine reliability, they say if you look after one it will last long time. Generally it's not reliable compared to piston engine.

I will attempt to rebuild it myself and see how it goes.
I have to admit, there is huge fun factor when working on these things. Can't wait to see what those rotors look like inside the housings. This motor overheated and blew the coolant seal. Lots and lots of white smoke when i tried starting it.
