Hi Everybody...



What do I do now https://www.nopistons.com/forums/pub...1047683473.gif

Move the post! https://www.nopistons.com/forums/pub...#>/biggrin.png

Move it to where, I'm new to this

off to the starting section!



mike

What year RX-7 is this for? We need more details. https://www.nopistons.com/forums/pub...DIR#>/wink.png

yeah, like whoa



mike

1985 model with 13B Peripheral Port, Supra 5 speed, 9 inch diff, motec e.f.i. and K&N filter

Noice! Now what do you need to know about a starter? (And im going to move this to the first gen section https://www.nopistons.com/forums/pub...DIR )

Well I don't know where the starter section is

lol, he was just joking around with you. Starters are usually generation specific and since you have a first gen, voila! https://www.nopistons.com/forums/pub...#>/biggrin.png

yeah, i'm guessing you have an rx4 bellhousing on there?



mike

I let my mechanic do all the work, I just pay him

haha, ok



mike

I don't know if anyone has had this problem before but what can I do to stop braking my diff yoak, the joint from the tail shaft to the diff https://www.nopistons.com/forums/pub...1047683358.gif

Smooth launches and make less than 200whp https://www.nopistons.com/forums/pub...DIR#>/wink.png





Seriously though, is the pinion angle ok? The angle of the driveshaft to the yoke?

Last time on dyno it made 310.8 HP and it's only braking when I go from 1st to 2nd and let go of the clutch

How hard you shifting when you do that?

I shift at 7500 Rpm

Yeah, but do you basically just drop the clutch when you shift or do you try and smooth it out best as possible?

Drop the clutch. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

AH YES. I know who you are now. You're mister yoke bracker. This man has gone through more yokes than I have through cars.

What that would be your 7th yoke



You're here know.



Speak to you later.



RX7 SP

My mechanic is replacing the yoke again and asked to check the alighment

Make sure he double checks the pinion angle.Thats the biggest mistake of swapping trannies and one of the most costly parts if you don't get the angle right.

I've seen 3500lb cars with 700+ Hp running ford 9" rear that have yet to break a

yoke. There has to be something mechanical binding. How modified is the rear

suspension to make it fit?



Raul

We found the problem. The yoke was not aligned and when I went to take off the diff would move and cause the yoke to twist to much and cause it to brake.

Special thanks to Racer X for your help.

I live for first gens.Its helping those owners out there that makes me feel better.Hope this yoke lasts. https://www.nopistons.com/forums/pub...DIR#>/cool.png

Nice setup, I was thinking of getting a supra box for when I get a s5 engine, but I think I'll keep the s5 box and if I break it, I'll get a supra one.

Good luck breaking it.My S4 T2 Tranny will be a challenge to break.I hear they can take up to 450hp before need strengthened gears. https://www.nopistons.com/forums/pub...IR#>/happy.png
