You can´t go wrong with GTO - they know their UN1s.

Yes, you will be able to drive the car in town, but clearly the 1st gear ratio is closer to the standard 2nd gear and will need a bit more care when taking off.

My GTO gearbox has these ratios, with the exception of 5th where I am standard at 0.76.

I´ve heard of the strength of the earlier 1uz-fe engines and those GT-Ks are nice turbos - should make for a very interesting car.

Good luck with the conversion
