I just wondering how many of u guy are running stock transmission with upgrade 3800stall. My supra is BPU my 153k mi goal is stay with stocktwin stock MAF stock injector. I just bought use jdm transmission with 43k mi for $300 would they fit in my supra. My goal is mid 11sec 1/4mi and looking for mid 400rwhp with stock twin. The last time dyno was last 2 year making 423rwhp with race gas at 19psi with stock transmission and stock stall.

With highier than stock stalls, heat becomes a problem and is most likely to break the box, so don't forget to fit a tranny cooler with a fan to help keep the temps down.My auto box stayed strong with a 3800 stall for a long time but keeping temps down is key to it all.
