T04R , 1.0 A/R divided or 1.31 divided?

I've got a T04R on the way (Comitatus' old turbo which I am getting from the guy he sold it to). It has the 1.31 divided P-trim hotside on it which he was running on a half bridge. I have a 1.0 A/R divided hotside at my place that I am thinking of putting on there instead. Which one should I run?

My goals are 450rwhp @ 20psi, full boost by 4500 preferably. The car will not see pump gas (except during break in). It is mostly a street car, I keep a barrel of race gas at my house with a pump.

Here are the details on my new setup. This is an 88 T2 with large street port s5 irons and s5 intake manifolds with s4 rotors, 720/1680, Power FC, and all the other supporting mods, which I will be tuning myself. My turbo manifold is stainless tubular (I think it was made by Feed or maybe Greddy? bought it off somebody here) with a Tial 44mm wastegate and 3" RacingBeat catback. I will be getting the wastegate plumbed back into the custom downpipe I am getting fabricated.

Use the 1.0 which is fine for 450 RWHP.

Yep, I would say the 1.0 for the street port. You need at least a HBP to quickly spool the 1.32 "Man" housing.

You are getting a good turbo, enjoy!

I have a 1.15 sitting on the shelf if you want to split the difference.

^ haha thanks for the offer. Oh and about that other turbo deal we were working out a couple weeks ago... I'm not sure if I got back to you or not, butmy friend is waiting to pay off some bills before he proceeds with the single conversion.

I guess I will stick with the 1.0 , that's what I was planning to do anyway.
