HTT Stock Replacement

[LBZ]

So I just noticed on FB that HTT is selling a BW drop in replacement for a stock turbo that fits with all the stock piping. Might be old news, I've been out of the loop for awhile.
Anyone running one of these or know anything about them? I like this idea better than going back to a VGT which is posing to be a PIA for me to round up the bits and pieces I threw away years ago.
Looking to run one with a Wherli kit that I purchase awhile back that was built to work with a stock turbo-if I ever get my truck running again that is.

I think you misread the post on HTT fb, the system they mentioned is not a 'stock replacement'. Its a complete turbo kit that includes pedestal, downpipe, oil lines, etc... they just announced the new compressor covers with stock style v-band inlets for the s300 turbos, so a LLY-LMM intake elbow with fit.

Ya I gathered that.
I'm just trying to find out if the exhaust outlet will match up to a stock downpipe or not. The other measurements height wise and side to side should be very close to the same so the stock piping will fit.
If it is, then my twin kit will work with it.
Hopefully will have an answer from them tomorrow.

HTT kits use an HX40 flange on the downpipe, so it wouldn't be the same as stock. But they could possibly machine the turbos outlet to the same as a stocker?

So it turns out although you can use the factory compressor housing connections, the dimensions won't allow for the use of a stock downpipe even if it was the same outlet size. So that plan is out the window for me.

Now I'm back to trying to decide what to do. Stock vgt, a bigger vgt than stock or change my piping to match an S chassis BW turbo which seems like a waste of money.

What do you mean the down pipe won't work? I was kind of hoping you had good news about this turbo

Why do have to use your stock down pipe? I couldn't imagine not getting a turbo I wanted because of something as simple as a down pipe.

I would never want to use the stock downpipe. What I meant by that is my twin kit was built to fit with a stock chassis turbo, so if a stock compressor inlet and exhaust downpipe fit on their turbo, that means the physical size of the turbo is the same as stock and therefore my twin piping should also fit.

The compressor inlet would be the same, but the HTT turbo is going to have an HX40 turbine flange, so in order to make your intermediate exhaust pipe to fit, you'd need to change it over to an HX40 flange. Other thing would be height, where does the pedestal put the height of the turbo compared to stock?...

Ya the flange thing would be a minor change, but it was the length of the exhaust housing that would be the issue. Also likely the height as I believe it uses a T4 pedestal. These were my concerns and likely why I will go another route.
