G25MR 5th gear swap info

[Motoxpress]

After some research and a trip to Pull A Part I have found another source for the illusive 5th gear. Pause for dramatic effect.... The non turbo MX-6. I also found out that it takes less than 20 minutes to acquire the gear from the donor trans. This swap is a simple fuel saver for the fastivas out there.

SWEET! Sounds like this could be a good upgrade for my Turnpike Cruiser project :thumbright:

I should do this swap one day :lol: 4k rpms @ 120 km/h (75 mph) really sucks lol

[Zanzer]

^^ WORD

Wishin I had a tack cluster this day LOL

[Damkid]

I've had my speedo buried and it goes to 200km/h and I was revving at 6k rpm, but my redline is 7500rpm so I had room to go

[Motoxpress]

Mark did you run out of DrPepper?? Pinning the needle to the corner store.

[Zanzer]

^^ Dr. Pepper AND Marlboros! Gotta get to a Quickie Mart STAT!!!!

I took that on the way do to the first SC meet when I was running a little behind schedule. The Escort 9500ix earned it's keep that day

what year of non turbo mx-6? also what tranny is it they have?

Well here's a writeup for the install (ignore the PG instructions. The 5th gear can be done in-car, at least I could in my Capri) http://www.clubprotege.com/forum/showthread.php?36485


From Page2 CrazyCanadian commented on the gear source:

G560-17-611B - Primary Shaft 5th gear
G514-17-308 - Secondary Shaft 5th gear

That should be the part numbers... Other wise its off the early FS 2.0L mx6/626..

I got one of my .717 5th gearsets from Clay "azgtx" on ClubProtege/TeamCapri, I think he gets $65 a set?
My other set I pulled from a 2g Probe GT transmission, apparently they're also .717 probably due to the short final drives

[Hot_Wheels]

is there anyway to identify the .717 ratio? it is the biggest correct? are there any taller 4th gear options??

[Rocketman]

Count the teeth & divide the numbers, you get the ratio.

I don't know of anyone that's modded a 4th. That gets tricky because you have to disassemble the whole trans & press bearings off etc. The 5th is outside of the main transmission case which makes the swap easy

[Hot_Wheels]

what do you divide the teeth by? so lets say i had 73 teeth what would i divide that by?

[Rocketman]

There are two gears that make up a "gear" in a transmission

+1 for Clay. I'll give him some reps here as words of encouragement. I purchased a VJ14-to-VJ11 swap kit and a set of brake calipers from him, and he was a fantastic seller. Highly recommended...
