Looking forward to seeing some pictures. Do you have any good sound clips of your exhaust by chance?
-sold...replaced by turbo e36
What happened to the87mm bore motor?
We’re kind of in the middle of going through it.
At this time we are of the belief that we lifted the head, hydro locked the cylinder which blew the cylinder walls out on both sides, then it looks like the piston grabbed the wall and stretched the rod in half. I’m talking with the component manufacturers now trying to work through it, I’ll post pictures eventually. Trying to drop this motor in tonight!

New old stock Burke’s . I actually think they are 8.8:1 now that I'm not in the garage.
The brackets will be nice stainless, 20 ga, CNC bent. With an AC line kit they will fit easily a 4.5" intercooler or without the ac line kit easily 3.5". Probably could push both of those 0.5" wider if you really got into the crash bar.

Kenton tried with his S54 to break 1000rwhp, but had a really hard time above 26 PSI. It seemed like the engine got to a point where it took more power to drive the turbo, than the airflow off the edge of the map was able to provide back into the engine. Backpressure went up pretty fast above 26 PSI manifold pressure.
I know of another S54 engine running a 6870 that is on it's 3rd turbo "trying" to make over 1000rwhp. I'm speculating that the failures were related to over-spinning the turbo, but I don't know for certain. (Nor does the owner)
The only thing I can think of to help the situation would be to run an even bigger turbine housing....or maybe look at the new G42 Turbo from Garrett.
Shoot I missed your replies!
Yes, I’m using a 6870 hp-cover with 1.15ar t4 divided exhaust. I haven’t seen anyone push this housing and a proper manifold. Lots of 0.8x opens and a few 1.0 divided. Both similar in volume really.
It has a nice 4” inlet, proper filter, good manifold. It’ll definitely crack 1000whp. It did 996whp at 5500 last time.
I was looking at the g42 for similar reasons, but this is it for me. 6870 is more than enough turbo.
—- onto a few updates. Sorry this is pretty sparse but we are so limited on time right now.
So we finally got the proper nuts from arp on Thursday. Assembled the motor that night. Takes a while when you’re fully disassembling everything and cleaning it.
125ftlbs on the head studs!
10mm vs 1/2”
Yesterday we finished the assembly, made up some new feed and drain lines, attached the trans (boy is the gs6 a monster), and installed it!
Ran into a few issues, we grabbed a new Bosch 140, and it was the rear nut Type, instead of being threaded, and I cut up two bolts and welded them together, quickly. 30 minutes later the head shot off and across the shop! Ground and rewelded it with more penetration and did the same thing!!! Wild.
Going to have to grab a few bolts and a plug for the head today.
Going to work up a new m50 manifold, clean up some of the vacuum routing. The car has been revised so many times they need to be cleaned up.
Got a new tstat, housing and hoses. This is really the most cleaned up the car has been!
I did get the custom Ac lines back.You guys won’t believe how expensive they were.... but it’s done and we can finally remove those awful oem lines.
And finally I’m updating my boost reference lines, they were 1/8” hardlines and I really feel it was hurting my low boost threshold. I could regulate down to 21/22psi. I was running two gates off a single 1/8” line. Going with some new 1/4” aluminum tube.

This might sound like an odd question, but how are you clearanc'ing the head gasket for the larger head studs.
When I went from 10mm to 11mm studs, I had a really hard time with fitting the head gasket over the studs...a 12.7mm stud is going to need a big hole.
Secondly, are you completely removing the alignment dowels on the head?

I'm glad you're keeping the forums alive. Better than Facebook groups in my opinion.
So for 1/2 head studs you also have to drill the head stud holes bigger right? Do you have to machine custom washers as well?
Keep up the good work!
The 1/2” arp washers fit. Barely.
There are a few more things we have to machine.
The head stud holes all need to be clearanced for the stud. There are a couple stud holes that need extra clearance for oil passage to the cams. And finally the two dowels need to be cut.
I did all of this manually myself. Quite stressful.

When I still ran an MLS and before I discovered that Cometic will make you any bolt hole size up to 14mm, this was the method recommended to me by machine shops:

But for the cut ring, my friend machined me a punch of sorts. It just has the single layer of tin and strikes through pretty well. But I'll probably just use the clamp method if I have to get another cutring.
Could you use this to cut the gasket?
