Haha yeah I hate it when people abandon builds. It sounds so loud and the turbo whistle from that GTX28 sounds SWEEEET!!! I will be posting a video hopefully tomorrow
Why yes! Yes it is!!!
We literally just got it running this afternoon. It was put back together a few weeks back and could not figure out why it wouldn't crank. Well it was taken back apart to find that the shop that did my engine put one of the cams 180 out. Once that was fixed, I had cylinder 2 and 4 misfires. Put different coils in and it cranked right up!!! It did not run long due to the coolant reservoir not being installed. So tomorrow that is getting installed, a temporary turn down will be welded on then I will break it in for at least 50 miles before it goes to MMotorworx to get meth and the tune!! So huge updates will come in the next week or so 😎
With one cam 180 out and "wouldn't crank", I'd be suspicious of valve / piston contact. Then listening to your last video, the rough idle makes me more suspicious. Have you done a compression check for bent valves, or maybe a borescope to look for dented piston tops? Hopefully the rough idle smoothed out after warmup.

Agreed. The idle was rougher and more sustained than I expected, but then OldBW's insight on the damage resulting from 180 deg cam misplacement would possibly explain that. My mini ran rough for about 5 seconds, then smoothed out on the first start-up after rebuild.
A YouTuber who showed their R56 engine rebuild did the same thing with the cams and bent their valves during cranking -- some viewer comments asked why the rebuilder didn't turn the engine slowly by hand before allowing it to be cranked?
Thanks for the update! This will all get sorted, I'm sure. The journey and mishaps teach us the most significant lessons during the boldest and most ambitious endeavors.
Didn't mean one cam. I didn't get correct info. It was both. The machine shop didn't install them correctly. No piston or valve contact and it is idling rough bc we have two huge air leaks, one being the old oil drain hole is still open it will smooth out once we get the leaks fixed. Heck the rings weren't even sealed in that video. Literally the very first crank up

Well I had a TON of things going the past few months but none the less, it is done!! We officially did an "idle break in" where we let the engine run for about 10 min varying the RPMs between 1500-3k. We changed the oil and now it is 95% back together. Also, a little bit of energy suspension bushing action never hurt so all that goodness was done too! We got the previous 2.5in exhaust mated to the 3in downpipe for now. As soon as I break in the clutch(50+ miles) over the next few days it is off to get meth and tuned by Mmotorworx in Frisco, TX.
Only 4 seconds long but I wanted to show how smooth it was now that all the vacuum lines are ran. My first startup vid I had to explain why it sounded like a big block with a 600 cam lol. In that first start vid I didn't even have my catch can on so I had a giant 1" diameter vacuum leak
still munching the corn! Will be here! Thanks for not abandoning the thread and leaving the audience in a lurch.
