New 5th gear for the R154 - how about a taller overdrive?

[Nick M]

That's why I posted it all. Also wanted to show how I go about rebuilding the transmissions

Then show putting the check ball and shift interlock together. :biglaugh:

I found another speed to rpm refrence. I am not sure why I took the photo. My overall ratio is 2.61:1 with .7 and 3.73. You can do your own math, I know you know how. The picture is for the masses.

.66 should work ok just remember it's a tiny pair of cogs and won't take a lot of abuse if you have a lot of power.

Which is one of the reasons I prefer a planetary.

I hate the feeling of a viscous coupling. *shudder*

The size difference is exactly why the cryo treatment is in place

3.2's are genuine Group A gears.

I dropped the transmission off with Jeff today! Hopefully, he can get it in soon, and get the testing started

 

[IJ.]

Well DUH

 

[Doward]

roflmao!

Quickly O/T - anyone else notice that the front wheel bearings are listed as a sealed Timken 510017?

 

[Doward]

Ok, the transmission is in Jeff's hands, as of Saturday. So now everyone gets to bug him about getting it in and tested so we can bring these out for everyone!

 

[SupraMan1987]

Bug him I will. I still want you to blueprint my trans and put this bad boy in.

 

[Doward]

That won't be a problem - as a matter of fact, I'm heading over to Jeff's tomorrow to give him a hand on his Supra

 

[Doward]

Open downpipe'd Supra lives again! Going to be spending the next couple of days getting the new R154 in, Jeff's building the midpipe, then it's time for more tuning
