The car also starts perfectly, warm or cold. I noticed the threads of my plugs on one of my rotors were thinly coated in oil when I pulled them out. Could that be because the OMP is injecting oil which is not getting combusted (no fuel) and just sloshing around inside the housing?
Whatcha guys think?

The injectors were never cleaned by me and I didn't see it on the spread sheet that the previous owner gave me.
If you kept the 1300's, they were brand new 850's bored out to 1300. I didn't want to chance old 850's since all the so called horror stories of 1300's blowing engines. I don't believe that's the cause but better to be safe than sorry!

Injectors are a HUGE priority. My car has 102k on the clock and the injectors appear to have not been a cause of the failure at all, but I am still going to service/replace them. other things: Spark plugs and wires. Would you replace an engine without doing such minor things to ensure proper operation? What if your last engine failure was contributed to by a drippipng injector? You would be subjecting the new engine to the exact same conditions as before. Go through and spend the extra money to have a reliable engine bay.
Reliability takes the whole engine bay, not just the engine.

I know it is off topic but things I replaced when putting a USED engine in my car:
Cleaned Injectors
New L1/2Coil Low Mileage T1/2 coils (16km)
New wiring harness
Oil Filter
Fuel Filter
Spark Plugs
Spark Plug wires
Fuel Pump

Bad news.
Did a compression test tonight - front rotor checked out fine. Rear rotor showed only 2 of 3 needle bounces :\
This ******* sucks. I guess I'll be calling my engine builder tomorrow to ask what the hell is up.
The weird thing is that sometimes the car randomly runs pretty smooth - you'd hardly know anything is wrong. I'm praying at this point that it's a stuck/sticky seal and that I didn't chuck a seal through my BRAND NEW GT35r.

If you don't do most of these things, it can get VERY EXPENSIVE.

Sorry to hear of the bad luck. I hope he stands behind the build. Good luck!

That's too bad. Don built my motor and it has been pretty solid. I used to recklessly run about 19-20psi on it too when it was an auto. Sometimes it would spike between shifts to 26-28 psi. I developed some of the symptoms you are describing more than a year ago, after showing off for a friend. On the plus side he now has a lifelong desire for an FD. On the minus I lost some vac, and it lopes at idle like it has a huge streetport. When I had the 5 speed swap I took it to Gotham. I asked Steve about it. Basically he said as long as the car is running I wouldn't worry about it. You might as well drive it until it quits (my paraphrasing). I know I will need a rebuild soon, but it just won't die. I beat on it pretty hard too. For that reason I was thinking of going back to Don, but your story gives me pause. What did he say?

+1 on getting screwed, he overported my motor and it was chipping side seals. I'm working on rebuild #3, and of course am getting the irons ported again by BDC this time around. Did you ever get in touch with him?

Screw that ,i'd be taking someone to court over something like this. People think they can just **** whoever they want and get away with it and it makes me sick the thousands of dollars that people steal or rip off from each other all the time from bum parts, shotty work, or just flat out conned someone out of their hard earned money.
Sorry, I ******* hate people who rip others off deliberately.

Yep, you nailed it.
My car is at Gotham right now. Don did a terrible job of porting the motor, which is ironic considering he used to be famous for his porting work.
The irons were overported and the ports seemed very rough along the edges. One of the side seals on my rear rotor was scraped away (a ton of shavings were found in my wastegate) and the seal completely snapped in half.
Don has avoided all of my calls after the incident and I haven't seen him since he built my motor. I've left him voicemails on his home number and he hasn't returned any calls, and has since closed down the shop.
Basically, Don fucked me. I've been a very loyal customer of his for 3+ years and I always had a great working relationship with him, but he really screwed me over bad this time.

Well unfortunatly this is the risk that we take when ameatures build engines and port them uneccessarily. Your stock ports flow more than enough to handle the hp potential of a Gt-35 turbo. People need to realistically understand what hp goals they want to accomplish during a rebuild. The rew engine has stock porting that's plenty large enough to meet most peoples hp goals. Had I done the engine, I would have recommended just a port polish and port match of the lim. That would have been plenty or that turbo.
