The problem is that you can't do a real proper compression test with the engine out of the car. And odds are that the problem with this build is a combination of using sub par parts in the rebuild and just a lack of experience. People think rotaries are easier o rebuild because there are fewer parts but that is just not true.

Call Rotary Ressurection or OJ imports for a lower cost rebuild and use this one as a core.

One of these two is not nearly the equivalent of the other. I will not say which is which other than, the more proficient has built A LOT of engines for members of this site, while the other has a break in policy that makes you think of the issues the OP is already having with expectations of low compression

Well I have known plenty of people (OJ's is south of me) with engines from OJ's and only one who had issues and they handled it well. I don't recall anyone having a bad experience and have heard nothing but good things about OJ's over the past 10 years or so.

That said, my engine was built by Rob @ Pineapple 40,000+ miles ago and has seen 10psi of boost since day one. I also would never buy a reman that has not had the rotating assembly balanced. You get what you pay for and I think it's all about the details and that comes with experience.

But of course, with a Renesis there are no guarantees, I have seen them not last all that long from just about every builder (including Mazmart). My buddies Drummond build is still hanging on as is my Pineapple build and my other buddy did his own and it has about 50k on it. But of course it all depends on expectations, for me, 40,000 miles boosted is more than I expected and the engine is still making great compression. Other who are NA may think 50,000 is acceptable, which is kind of silly to me.

My purpose here is not to attack any companies and I try hard to be diplomatic always on forums. I am specifically addressing the topic of a rebuild being difficult to start, when properly installed. That is not the way it should be and it seems like our RX-8 community is growing accustomed to it.

No offense intended, just a desire to encourage higher standards.

Oh I agree on the point 100% that a rebuild should fire right up and if it doesn't it's because it was not a solid rebuild. I have stated that in many threads.

But you also get what you pay for, so if you are buying a $2000.00 rebuild, you can't expect it to last 100k. A that price point I do think it reasonable to expect some corners to be cut.

I mean only in the rotary world do people think $3,000.00-$4,000.00 is expensive for a rebuilt engine. But I guess it is expensive when you consider it will likely not last to 100k.

Literally only in the rotary world do people think that $5k is absurd for an engine rebuild. I'm already working on budgeting for one despite not needing one. Because Mazda decided to shove a Race Bred engine into a commuter car. I'm still very okay with this.
