Factory repairs on my '85 GSL-SE (injectors, tuning, timing, vacuum) were top quality and thorough. Jonathan is super knowledgeable and was able to get the engine back in alignment to OEM specs. The car has never run so well! My new go-to spot for all things rotary.

Didn't even get the chance to do business with them, I was never able to get ahold of anyone. Tried calling every other day for about 2 weeks with no answer. I tried email too, with no luck. It seems to maintain a rotary you need to have social credits and be friends with someone in the rotary business. Seems they just ignore the "little guys".

I saw a few others complaining of engines he built not being right. Especially the semi-peripherals. I also saw how he handled others when they brought it to his attention that there was a problem with his work…Long story short, don’t waste your time or money. I just got my engine back from him in the last two months and like others have experienced, the work is poor at best. Did a coolant pressure test and the engine fills with coolant. Totally unusable and will need rebuilt. Not even going to try to work it out with him after seeing some of his social media posts.

Not my experience rather some one I know ordered a pp 12A Built by goopy as soon as he fired it up it Grenaded so he contacted goopy and was then promptly blocked he’s had a bad run around recently and this doesn’t help I was thinking about going through you guys but not anymore I’d rather have some 60 year old rotary head rebuild my engine in a barn thank you.
