holset small h1c questions?

[90tsi6bolt]

I recently purchased a used holset small h1c that needed a rebuild. I have a couple wuestions . should I stay with the 16cm twin scroll hotside or would it better to go bep hx35? ( if it will fit in the housing)? What power goals can I see from this turbo. I don't want it to take forever to spool. my gsx is still driven regularly.

I think I could get close to 500whp out of that turbo on my car. Looking at your setup, on pump, you should get 350+ but you'll need more fuel and a better fmic.

Last time I actually tried to make power on 93oct was with my WH1C, with a china intercooler. I went 117mph weighing 3350lbs. that's probably close to 400whp. I had more cam and a few other tricks. That was at about 28psi, and no timing.
