Hi stall converters without a trans brake. How to launch?

I'll be interested to know your fuel econ before and after

And how it is to drive on the street!

my stall speed with this convertor on the 1j was around 3400 rpm, on the 2j bottom end it only stalls to about 2800.

1jz and 2jz converters are different from what mike tells me.

So with the exact same convertor you stall speed went DOWN from 3400 to 2800 with the 2J bottom end? What type of convertor was it?

This flies in the face of everything I have ever heard about convertors. I thought when you applied more torque to a given convertor you could push it higher.

Yeah, 2J and 1J convertors are different. They wont even bolt up to the flex plate properly and wont go go onto the input shafts of they other type of trans. The 1JZ one is smaller, which is why it stalls up higher.

You need brakes and tires!

I don't think drivability will be bad as the flash speed is 2300 ro so RPM. It won't effect economy much becuase I manualy use the lockup clutch.
