thank you very much..

 

I have heard that for the 20B swap you need to change out the stock 6 speed and change the rear end in the RX8 due to the power of the 20B. Does this need to be done or is the stock 8 strong enough to handle it.

Thanks

 

I would say that the trans has to go. I think the rear end it's self can handle the power. However the half shafts can't. There are half shafts available that can handle the power.

 

You could stay with the tranny but only if you are going with a conservative setup and treat it like a baby... Ive broke 3 8 tranny's ( all 2nd gear)and my t56 is starting to make weird noises...

 

Define "Conservative". Stock 20Bs already push 300/300. Do you think the 8 tranny could hold 375/325ish?

 

Id say 400-450 would be OK, but and that is a big BUT.. If you like driving hard 2nd gear is going to break most probably with a NA 20B. My second tranny I broke 2 hours after installing it and the car was at 12 pounds of boost. I had just lower it thinking It would help to save the new tranny...

 

Check out this tranny.

Made as basically a drop in for RX-7s. Seems like it works OK for a DD as well. People on RX7club say it will hold 600ish comfortably.

Its pricey but nowhere near what other SMGs are.

 

my car broke two (guru's tranny) of then it cant handle more than 500 rwhp!!!
consider to install a an automatic or shiftronis tranny is best for the street use.

 

warning warning this is only a test of real power ! ! jajaja



click image for video . .

 

any track or dyno video??????

 

that does look fun

i'm starting my own thread soon. it'll be titled: help me finish my project or something to that effect.

glad you guys are still on the forum tho!

as for tranny, i may just end up doing custom tranny case bracing with the FD tranny.

i just bought a floor lift which is to be coming any day now.

 

i was looking at the transmission that you were using and what type of paddel shift kit are u using with the FB performance transmission and how many shifts do u have to shift up and down.

 

Today my friend Rey visit me at brings his new GTR to my warehouse.
This one is one of the first GTR's on the island. He give me a ride and the car is really fast and the best think is that that there is no tire spinning.

My friend Rey is also a Rotary fan he owns also a RX7 turbo II and a 1993 RX7 both with over 600 hp at the wheels.

Nice car... The only thing I dont like about it is the price .....

 

There's Shiftronics actuator unit (paddle shift )(Italian Made),is a servo motor ecu controlled, this tranny is a special unit with a gearvendors unit installed a the end of the tranny we can shift up to 8 speed with this unit but we set it just for 6 speed...This tranny have built in a transbrake control too. for hard lauch..

 

im digin the setup. About how much would the type of setup your running will set me back and would i go thru FB performace to purshase the transmission ?

To whats engine you would plan to install it? Renesis, REW 13b, cosmo, 20b. and kinds of mods you plans to do? the 4stb from FB performance alone would work good for your application alone now if you plans to runs more radical HP i can send to the the total recipe to run it wild like F1 Does.

I plan to run it in a 20B my goal is about 950hp, i plan to do most of the work my self. but i do like the paddle shifts. But if u can i would like that recipe

 

Gaby tunea PowerFC? Quiero llevarle mi carro a ver cuanto le sacamos...
