Holset H1E /22cm spool

[Diehardmitsu]

I have a 60mm H1E turbo that will be going on a 3 liter I-6 motor. There's not much info out there on this turbo with the given application. What would be a good guesstimate on Spool/RPMs using the divided 22cm housing with a twin scroll header? Can the Holset Guru's please chime?

Thank you

The h1e and h1c are older hx35s with the right manifold in a t3 split scroll configuration and assuming by i6 ur talking about a 2jzgte engine. I would expect u to see quick spool somewhere probably around 2800 and full spool by 3500 rpm the 3.0 i6 will flow more exhaust gas than a 2.0 i4. And the larger displacement will help you out

Yea its a 2jz engine. I believe the H1e is similar to an Hx40, turbine wheels are same 76/64mm were as the hx35 are smaller.

I personally don't kno the specs on a h1e. I was running a h1c. But I had no problem with spool. On a bep or t3 split housing
