might have missed this but whats the exhaust housing on your turbo ? T4?

V-band.82a/r....
its on my list to upgrade but i have no room for t4 divided.
I think biggest t4 tangential is .96 a/r and i don't know how much different it will make compare to .82 vband.
I just don't want bigger turbo lag so decision decision haha

Find a way to get that T4 .96 a/r in there. You won't notice any lag, but it will pull like a freight train after 4k rpm....trust me.

The VE of these engines is phenomenal, and they respond extremely well to large turbine housings.

Thanks for response
I have no problem to fit t4 tangential . I will also make new pipe from t4. (I think from 2.5 to 3 inch)

With your pipe design, you would not be able to take the advantage of the twin scroll design anyway. The largest T4 available for that turbo is a T4 1.32 a/r, which is a twin scroll. The T4 .96 a/r tangential design is the next largest, so you should be able to put some good numbers down with that.

As for the up-pipe, you should keep it 2.5", as that is plenty, and going to 3" would only slow the spool.

Bigger turbine HSG

Did you get this new turbo installed ? Looking to make the same upgrade

Nice work, and great numbers for 11.5psi.

How does the .96a/r look over your previous turbine housing...I bet there not much difference in spools.

Not yet.
Also changing to ID1700 and dual fuel pump setup before new tune

My up-pipe is only 2.25inch so i think i need to change it to 2.5inch.
