Torque converter selection help!!!

[neilb]

Hey everyone, I'm currently looking into upgrading my torque converter, and need some help. I am running the turbo 3.8 in my Camaro using a 700r4 trans. My question is I'm looking for a stall rating around 2800rpm. When searching for torque converters are the stall rates based on small block V8s? I've read that if your running a big block to add approx 200 rpm to the rated stall. So does this mean I should subtract some rpm to the rated stall since its a V6? My cam is a 212/212 comp cams, running a cpt60 turbo , and 3.42 gears. Also, are the torque converter from a 200r4 and a 700r4 interchangable?

Thanks for any help, this has got me all confused!

You probably have a 30 spline input shaft vs a 27 spline of the 200. I can spec you a 30 spline converter with a 2800 rpm stall for your motor. Cost is $500 for a lock-up.

The current transmission in the car is the older 27 spline unit, but I am buying a low mileage unit from a co worker (the old unit slips, and has a bad vibration in overdirve). I'm thinking (and hoping) the new one is the 30 spline, but I'll have to check when I pick it up. Before I install the trans, I'll be upgrading to a corvette servo, and installing a shift kit. Are there any other upgrades that you would recommend for a mild street car?

If I decide to go with a PTC, should I just contact you through turbobuick.com, or through the PTC site?

Thanks for the help!
