GT35/40R what a/r for turbine?

[dwhe009]

Hello,

I have a dead stock 1uzfe out of a 1991 crown. It is in a single cab 1990 hilux and i have just about convinced myself to turbo it with a GT35/40R and run around 10-15psi on street gas (nothing wild)

My question to you all after searching this wonderful forum is what a/r should i choose for that turbo? I want boost at 2500rpm to 6500rpm. Anyone have this turbo on there 1uz?

Cheers for any help.

Since this is a ball bearing. I would suggest .82.

Dave even a little higher may be a good idea?
1.02
the 2jzgte 3lt with a 1.02 ar has good boost around 3500rpm
so May be the 4lt could be a good for a 1.02ar at about 2900rpm
that way the boost will be on board Just before the stock cams start working (3500)

1.06 works well on Fords 4.0 turbo...
