Stall converter

[wilsonw218]

I have an 87 GN. I am wanting to change out the stock converter. What stall speed and converter size do I need to go with? The turbo has been upgraded along with the 3" exhaust pipe. The heads have had some mild work done to them. I am currently running the car with 18lbs of boost. The car is trying to push through the lights @ 2300 rpm. The 1/4 mile time is a 13.47 with a 60 foot time of 2.370. I spoke to a tech @ art carr and he recommended a non lock up with a 3200 stall.

Stock camshaft? Do you know what size the turbo is?

If your pushing through at 2300 I wouldn't want to go much looser than 2800 but it will depend on the cam and turbo size.

Stock cam and I am not sure of the turbo size. I am sure it as been upgraded.
