1GR-FE Manual Transmission Options

I’m building out a pre-runner, fab and suspension work is almost done, so resale value is irrelevant. I’m keeping the 4.0 and currently having it rebuilt as a 4.7 stroker, supercharged with LTH, 3” out catless exhaust. The goal is 600HP or so after tuning with similar TQ. The question here is, what can the stock manual trans handle, and what are my options if it won’t hold up to these numbers. I’m already planning on doing a new driveshaft and already have a Ford 9” in the rear. Thank you

 

What supercharger do you plan on using to make 600 hp? Have to ask..

 

I’m looking at the Harrop TVS 1900 kit, though I may have to change the pulley out. I’d like to run about 10psi
