You won't get 200 out of a 1.6 at "low psi"

This post made my brain bleed a little bit

Did you already buy a turbo manifold?
If not I would go with a TD04L-13T from a Subaru

I say for 12psi max boost

Tasos, why are you measuring in PSI? Why does it have to be low boost?

Cliff notes and an estimation:
2554 makes 200hp at 16psi and 180lb/ft at 3200
2560 makes 200hp at 12psi and 180lb/ft at 3800
2860 makes 200hp at 10psi and 180lb/ft at 4500...

See the pattern?

If you want 200hp, you want it as quickly as possibly providing it doesn't fall on it's face. For you, I would recommend a 2554 and run it at whatever PSI makes you happy and your EMS/Clutch/Rods can support.

If you had a 1.8l I would recommend either a 2560 or a Borg Warner 6258.

I want low pressure because i have factory pistons and rods is .and dont want engine promble from pressure.

That's not how it works, you have a lot of reading to do.

Torque kills rods, not pressure.

Factory pistons have made well over 280hp no problem.

Ive run 325whp reliably long term including runway events on E85 in a rods pump and bolts only motor. Stock pistons. Ive done a few cars like this.

Thanks. I wasn't sure what the consensus was on stock pistons. I just threw a number out there higher than he was probably expecting.

I, for one, am fully supportive of all "what turbo for my 1.6L" threads being moved to the Supercharger section
