Yea, the seller said it was if an ISX. I don't what power rating, but still pleasantly surprised to find out that there are 66mm models and I stumbled across one. Anyhow, quick update: project wound up on hold for the month of May. Got caught up in a few project on the house and spent memorial...

No electronics, there will be a double acting pneumatic cylinder that will actuate the vgt. Boost pressure will close down it tighten the turbine, and dive pressure will work to open the turbine. The two fight against each other leaving the turbine vanes in a position that has boost and back...

Can anyone who knows these turbos tell me what is going on. I thought that there was only a 60mm and a 64mm compressor for the 451 frame Holsets. This is what I found when I opened it up. The odd number of blades makes getting a real precise measurement near impossible, but the best I can...

Yes, from what I understand the 451 framed turbos came on higher HP rated cummins ISMs, ISLs, QSMs, M11s, lower hp rated ISX motors, as well as Volvo d12s and mack MP8s. The 551 frame turbos are the most common on the bigger 13 & 15 liter commercial engines like the ISX, MP8, etc. That is what...

I am not sure but most likely an ISX. The turbine housing is weird, it has an odd flange, and a generally weird appearance do to the vgt. I don't believe it should limit anything for me though. It is 29cm and the turbine wheel is 67/64. I am really more confused by the compressor though. I tore...

That is way too electronically over my head. LOL I'll be sticking to mechanical. Anyways here is a couple of pics of the he451ve turbo The turbine housing on this thing looks massive. The physical size has got me worried but it should breath well. :lookaround:
