will 20b tt work with stock 6 speed trans?
im lookin to buy a 20b tt and i know a little about it, but nobody seems to be able to tell me if itll work with the stock 6 speed transmission, if anyone out there has any info please share.
thanks. |
I doubt anyone has tried it . The stock trans is not a strong one .
That said I'm making some reasonable power and have no complaints - so far . |
are you planning on a puttin a 20b in your 8?
|
yeah for sure
|
When you say you know little about the 20bTT how little? How much work were you planing on doing yourself?
|
the whole installation thing scares me, this would be my first big project. i work with this guy, hes been a tech for 27 years so i told him about my idea and hes willing to help me out with whatever i need help with.
|
I know the thread I am about to post is 47 pages but based on the amount of money a 20B will cost you need to know what your getting into.

mike, do you REALLY know what youre getting into??? you do understand that this IS NOT a direct swap, time, money and LOTS of fabrication will be needed to pull this off....if it was a direct swap a lot of us would have done this already
|
Mike- your looking at about $5000-8000 for the engine alone- used or rebuilt. And your looking at another $15000 for time/labor/fabrication/tranny/etc.
And by the way, most people who run 20bs, run RX7 FD 5 speed trannies, so....Your choice should be the same as theirs....not a 6spd. Search for AngelJoeV he has a 2004 Winning Blue 8 with a 20b swap+ bigger aftermarket turbo. He also has Youtube videos, so search for them. Good luck! |

i no nothing about the transmission myself, i just go by what my mechanic tells me.. he's going to try about 700hp in the near future to see if the tranny holds up. He tells me the rx8 tranny is bullet proof. I've heard people say other wise. He even told me that another guy in San Antoniio has a 3-rotor with the 4speed auto shiftronic tranny running about 450 WHP.. all i can say is dayum!! Im suppose to get my new slotted and drilled brake rotors put on by him.. when i get a chance to goto San Anotonio I'll ask more questions. Ill even try to take a ride in his car. Last time he had it taken apart to work on something.

/\ chickenwafer blew his trans after only a few days running at 325lbft torque ......
|
The answer to the original quiestion is YES. The tranny will fit the 20B. It wont HOLD its torque but it will fit. Trust me, I know.... :)

I went through a couple of rx8 stock trannies. As long as you stay with street tires, be very carefull with 2nd gear and stay below 8 pounds of boost ( BOOOORRRRIIIINNNGGGGGG), it should be fine. all I broke was 2nd gears. STAY AWAY of drag radials.. I used them and the tranny went in about an hour..... counting the time it took to get the tires on... hahaha
PLEASE take into consideration that I love acceleration and I drive my car HARD... If you baby your car then it will last forever, But who wants to go through all this for that... |
angeljoelv...what transmission are you running now? and check this out for me and lemme know what you think, they come with less than 20k on em...

An auto 20B rx8 in San Antonio? The video shows him passing a BP gas station :squint: I know Tito a little from through the years and last he told me he wasn't really in the business of major jobs anymore. |
