Yes, its what the title says, curious to know what your opinions are, its been posted online before so youve probably seen it.

posting on any page regarding a 2h engine









 
70 psi at 2200rpm only done the head gasket which is copper and a 12mm td42 pump rest is stock

70 psi on an idi engine with nothing else touched means that engine is going to explode very quickly. Either the crank will break, or a rod is going to shoot out the side of the engine. Those engines just weren't made to handle that kind of pressure.

:meh:

Im sorry, I would have to see video to believe that claim. I am not sure what the point of 3 turbos is with the narrow rpm range of a diesel. If the motor revved to like 12k rpm then ya I could understand 3 turbos.
 
this is from a bloke who tests limits on 2h engines. heres one dyno run pushing at about 30-40 psi i think


more videos to come on the triple setup.

for fun and testing how much a stock engine can take
 
I've had another look at it and I think there should be another pair of wastegates across the primary turbos. Either the primarys are too big to spool early or too small to run at max rpm without getting very high exhaust manifold pressure.
The wastegate on the secondary is almost redundant as flow will be limited by the primaries.
Also if you are up to 70 psi you might want to strap across the flexy joints to stop expansion and blowing off the hoses.

A 2H is literally just about the last Toyota engine you would want to do that to. It's just confusing.
