BSP LS1 Rx7 - 10.40@134 - Vid Inside In a continuation of our previous post about our project LS1 Rx7 (BSP RX7 – Last 6 speed dyno) we finally have the trans swap complete and up and running!
What looked like an easy swap on paper – T56 6 speed transmission to a 200-4R 4 speed automatic transmission (from a fellow LS1 RX7 owner no less) - turned out to be more work then imagined.
We finally made it to the track, could only make 1 pass that night, and were launching off idle, but went 10.40@134.

Thanks!!
Motor is an Ls1, stroked to 383 with our Ls3 Small Bore heads (Stage 2). We're still using a factory Ls3 intake, our 92mm throttle body and stock Ls3 intectors. 11.1:1 compression, 1 7/8 headers, 3" Y to 3 1/2" single. Cam is a custom grind 248/259.
Still using a Mazda diff w/ 3.91 gear.
