RX8 or Turbo 2 Transmission Swap your SA FB RX7

[@TheRealJoshN]

That rod gets cut 103mm and like you said, make sure you mark and measure where that new hole has to go for the shift selector cup doodle, BEFORE you cut the it off. Its good fun figuring out where that hole goes afterwards :D

[@RADPotential]

Yes sir!!! Its a pretty easy procedure if you don't get ahead of yourself haha!!!!

[@bradylynch9653]

Just in time for my break at work! I have a 1978 rx7 and your vids have been great!

[@whatisanamelol]

Cool video, thanks for sharing. Most FC Turbo boxes have been abused, so maybe RX8 boxes are a better option...maybe. Thanks again

[@RADPotential]

Getting harder to find FC bits these days as well

[@juanp2138]

Thank you for the information 🙏🏼

[@MorganizerT]

Idea for an FB swap, could you put in a concentric clutch slave (would love to know if this is possible) which would then give enough clearance to move the engine and trans back by a couple inches? That would put the gearstick where it needs to be AND give the car better weight distibution.

[@RADPotential]

Id have to look. The hard part would be making sure the slave had something on the transmission to push against. Clutch side would stay the same. You would have to find a safe way to route the hydraulic line as well. I can look into it. We did a t56 in my mom's 57 chevy using an aftermarket slave/bearing combo.

[@zidelious781]

Amazing info! To verify, the Mazdatrix turbo driveshaft for sa/fb will work with the rx8 trans?

[@robertorx7813]

Do you know if an fd driveshaft fit turbo two transmission I’m ta talking about the front side not the rear

[@RADPotential]

The output shafts of those two transmissions are the same IIRC.

[@youngbreed72]

Is there any rubber or poly for rear mount or is it mounted solid? Any better pictures of fabricated mount? Loving the channel, I keep finding answers to many of my questions. Keep up the good work.

[@RADPotential]

Solid mount if you have solid engine mounts. The First gen crossmember has rubber isolaters on it. So you can solid mount it to the crossmemeber due to the crossmemeber being rubber mounted to the car

[@youngbreed72]

@@RADPotential I was hoping you said that. Thanks.

[@RADPotential]

An rx8 trans as well wont have a provision for a standard rubber mount as you will use the power plant frame mounting points to hold it

[@favarer93]

Nice video!! Does the speedometer of the SA or FB works with the Rx8 transmission?

[@RADPotential]

No, the rx8 has a electronic speed sensor.

[@jadeynolah5832]

where did you get that bridge port 12a?

[@RADPotential]

Buddy built it many years ago. I do porting and engine building as well

[@jadeynolah5832]

@@RADPotential how much do you charge for a bridge port 12a? If you have Instagram we can talk prices there if you want

[@gqw247]

I just bought a 79 rx7 and I want a 13B motor. I really like your videos they give great information!! I am not finding much 13B motors except those that come from a rx8. I see them selling the motor and trans together. Will taht fit my SA? Also what else would I need? Thanks for all your advice.

[@LightGesture]

I have a used rx8 transmission and an rew stage 4 ported RE-W.... Can this work?

[@krayziebonejr]

Hey just a quick question, I just finished bridgeporting my 12a but I was curious about the stock fb 5 speed, could it handle it?

[@RADPotential]

Yes you will be fine. It won't like 8k+ rpm shifts though

[@amirrx3817]

I use 12app with fc transmission, is it suitable if I use fc lightweight flywheel & fc rear counter weight ??

[@sailingwillie]

Did you run into the problem of the RX8 slave cylinder not having clearance from the 1980 oil filter pedestal? I have competed all else but ran into this.

[@RADPotential]

I ran a Racing Beat oil filter block off. And had a remote mounted oil filter.

[@sailingwillie]

@@RADPotential Thanks for the reply. Appreciate the suggestion but due to the placement of the 12A oil filter there was still no room for the remote option. The overlap was too great. So I created a bracket the would turn the cylinder 90 degrees. I have pics if you would like to view.

[@douglaskane6877]

@@sailingwillieI would love to see a picture I’m running into the same problem

[@QuantumPlaysOfficial]

What if i have a ford 9 inch rear end will it still work or am i gonna have to do some fab work

[@RADPotential]

Only difference will be the driveshaft

[@adonbanchamek2254]

Dumb question: why would you want to swap the FB 5 speed trans? Isn’t it good enough? Is there a difference between the 5 speed SA and 5 speed FB?

[@RADPotential]

Imo going from SA to FB 5 speed isnt any improvement worth the work. Slight gear ratio changes. But otherwise nothing major. FC gear ratios are a bit better. But if I was going to swap to anything it would be rx8 trans

[@robertorx7813]

So I need a adapter to an rx8 flywheel.

[@RADPotential]

You need the 6 bolt counterweight that matches the rotors in your engine. With a rx8 lightweight flywheel

[@boombloom282]

I have a 1984 rx7 gsl-se and I got my hands on a 2004 RX8 I plan on putting the RX8 motor into the RX7 the only problem I'm having is the engine mounts do you have any recommendations

[@ADudesRotary]

Get billet custom made engine mounts

[@ethanam3]

Racing Beat sells the front engine mount.

[@sorrynotsorry7803]

You know if there is a difference between the 87-88 TII and the 89-91 in terms of install?

[@RADPotential]

I do not believe there are any mounting variations between the 2. I think the reverse wiring may be different. And I know the S5 is stronger

[@stevejk8362]

@@RADPotential I've got an 85 cursed with an automatic, this video definitely helps me decide what one I wanna shoot for.

[@MorganizerT]

I just shared this with MCM... If they use it I really hope they give you credit!
