What's the price of a reman? We may ask for a refund after sending this one back.

You guys would have been best off to buy a reman from Mazda.

Looks to me like one of the side housing could have cracked or broke. Which would not be the installers fault. It would be from using faulty parts in the rebuild. I have seen that happen a couple of times from motors I pulled apart to get good parts from. Good luck in dealing w/ the rebuilder. I hope they treat you the correct way.

I've seen them around $2,500-$3,000

Guys, to follow up on this about a month later, we sent the engine back and the company took good care of honoring their warranty. They completed the work fixing what they told us was a cracked housing, that they missed during the first build. The engine is back, in the car and running.



I have one question now. There's some good smoke on warm up, not blue like oil but more white, like coolant but it doesn't smell like coolant. The smoke subsides once the car is warmed up. The car is catless and I wonder if this is the normal behavior of the rotary since I'm experienced with piston motors moreso than rotaries.



Finally, we set the boost to a conservative 7 psi now after porting and doing the sequential turbo elimination until the car is tuned with a Power FC. After being on the boost and letting off there's a substantial amount of smokescreen for about 5 seconds. The turbos were visually very worn, no shaft play persae but the turbine housings were cracked and they both looked quite worn. I wonder if the seals on the turbos are failing and causing both smoke issues. Any thoughts? Engine issues again? Just paranoid.

How the hell do you miss that?!?!

There is usually a little smoke from rotaries at start up. Especially if there is no cat. Just make sure its not coolant. It sounds like the turbos to me as well on the other smoke issues. Glad to hear they did you right. Good luck.

The smoke at startup is normal expessaly if you live in a cold, wet climate. During the fall and spring it happens to me every startup.

Thanks guys. I think everything's fine. We "missed that" because we didn't build the engine and something was cracked in the waterjacket, something that's not visible from the outside of the engine.

"U" refered to the place that built your motor. It should never be a hit and miss as mention when buying motors , most companies I see are even half assing ****. This should have never happend, people should be paying careful attention to a motor they are building...

Yeah, missing a cracked housing is like pretty rediculous.



at least they honored their warrentee
