20b with th400 or th350 trans
I am looking into getting information on running a th400 or th350 trans in my 93 rx7 20b. Recently broke the stock trans. It held 719whp 590tq tq for awhile (no launching lol). It is a track/street car. Any information anyone has on companies or people who would have knowlege or ideas would be greatly appreciated. I only know a few running the th350, but that is with 13b's not 20b's.

i never seen anyone run either of them to tell you the truth the supra guys do run them on the track cars i know the 350 is lighter but takes less power and 400 is a beast but its a heavy mother most american car guys use them before putting a glide in and theres a bunch of dif places that built them you can most def find one by you just do some homework in your area find a shop with a good rep

I run a super-comp from performance automatic inc. , full manual valvebody, with a transbrake... C4 ford tranny ..Im only at 500hp-400ish torque but this thing is CRAZY faster (acceleration) than my stock 5 speed
I actually have an extra bellhousing (from carribean transmissions, puerto rico custom made to fit mazda to C4) if ur intersted, i dont want much for it

freddy brown performance in new york had a custom convertor made. he is one of the only guys i know that does this for the rx7. we dropped off core th400 trans and stock rx7 flex plates and he built me a 1,200hp 1000 tq trans with trans brake and custom convertor. stock bell housing. definitely a tight fit though, lol
