Transmission Options?

WankelsRevenge · 04-07-2013, 06:56 PM

So Im having quite a few problems finding a transmission to swap into my 86 NA, which has got me wondering what other options might be feasible. Im mostly curious about what options are out there and are recommended without needing a ton of modifications to get everything to work. Also if anyone has any odd setups they like and would want to share.

What are you trying to accomplish by doing the transmission swap?

+1

power goals and intended use are quite important.

easiest and cheapest of course being just stock and turbo components.

Well right now my 2nd and 3rd gear schrynos are on their way out, so a transmission swap will be needed eventually. Sadly Im having problems finding a S4 NA one and was just curious what my other options were without having to do any huge modifications.

depends on what you mean by huge. but if it's a stock car then just keep looking for a used transmission. you can use a series 5 n/a transmission as well but you will need the crossmember with it from a series 5 car. the rest is all bolt in with no difference.

an FC turbo II transmission will also work but will be a bit spendy since you need the transmission, starter, crossmember, clutch, flywheel, throwout bearing, slave cylinder and a modified driveshaft or ream out the holes in the diff flange with a stock turbo driveshaft.

most anything else would either need an adapter plate with all the above and/or transmission input shaft modification.

you could also just look into having it rebuilt, which usually runs about $600 for the n/a transmission.

I run a 6-spd in my FC.... it bolted to the engine

an RX8, which requires about as much work as the TII transmission which is still more durable, and likely more expensive unless you get lucky. the RX8 also requires a fabricated transmission mount since it uses a power plant frame.

Clearly you don't know about what I've done to this particular transmission to make it fit, work, and stand up behind ~400rwhp and repeated track days..... onto my favorite question,.....

What makes you think the RX8 transmission is weak?

because i know of owners who have repeatedly broken them behind n/a renesis engines.

Define broken.

since i had another 8 in with a "broken" transmission i figured i would take a picture for you..

i have never pulled a 'turtle' out of any other early transmission, though they have different weaknesses.

was not turbocharged, did not have an engine swap, all 190ish whp glory of the renesis engine.

you did say that, correct? i suppose you are half right. the issue isn't with the amount of torque input, it is with the amount of output and the problems in the back half of the transmission.

i was able to use FB transmissions, but i think i either 1. changed the tail housing (somewhat easier) or just fudge one of the transmission mounts some.

Whizbang · 04-07-2013, 10:50 PM

id like myself some RX8 transmissions. friend has two he would sell me. then i need to talk about fixing them.. (2nd gear is pooped, as you would expect)
