Hello, I need some help choosing a correct torque converter for '02 gmc 4.8l stock internals 90mm tb with a tvs1900 magnacharger 7psi of boost. What stall,size and should it be a lock converter? Trans is a bowtie overdrive stage 1 4l60 good for 500hp. Any suggestions.

 

I'm no expert but just from what I've learned when selecting my own converter you can't go wrong with a 3200 for a daily driver. With a roots blower you'd have a good bit of low end at your disposal so you shouldn't need to go super high. My converter is a circle d. Haven't installed it yet but I'm very happy with their customer service and ordering process. Give them an email they'll help you out.

 

you need a tight low stall.. try a circle D triple disc 2600-2800

 

Yep, same as I went with and a 265mm.
