Here's a pic with some of my old 02 tranny parts for comparison.

Double synchros on 1,2 &3 since they didn't have any 4th in stock so I just did single there and all have needle bearings. Gerard had to order the synchros for me from Japan since when I looked them up through Montgomery Mazda online they crossed over to our OEM synchros as a replacement.

FYI 3 double synchros came out to $340US with the $3240 PAR set along with my bank charged $99 for a currency exchange fee?? So came out to more like $3700 plus I'm waiting for quotes on new bearings and seals and 3/4 shift fork!

Adds up quick , huh ? Make sure you get a professional transmission shop to put it all together.
 
I'll be doing this myself and although I don't have all the tranny terminology down I am the Sr. Design & Manufacturing Engineer and part of the day Machinist for a Mold tool and Die shop. I have everything I need and will be much more careful and precise than any of the monkeys I could have do it.

In that case, build yourself the tools you need to measure the tolerances as per this guide:

I really urge you to triple check the tolerances, as not enough tolerance or too much will lead to destruction of the gearset...


BTW, if you do decide to build the tools for this, make two sets becuase I defiantely would buy a set from you !!!!

It looks like the only thing I'll need to actually make is the adapters to torque the input and output shaft for bearing pre-load for shims! Dial indicator and a lathe and feeler guages.
 
It looks pretty easy! I'm thinking of using my old tranny 5th gear and tack welding a deepwell socket to it. Bam done! Both shafts have the same spline!
 
Thats alot of damn money. Hope these gears work out for everyone. Damn. $4,000 almost, not installed... ouch.

I was talking more about the spacers to bring the diff up from the bottom casing to measure the shims needed, and the spacers that seperate the upper and bottom casing...
 
lol at 4k...

for my trans build i am getting 1-4 straight cut, 5 helical- longer gear ratios based on danas calculations, double synchros, quaife differential. ROFL @ 6k plus.
 
REALLY? What else... cuz that dont appear to be 700 ponies to me. BOV, piping size, shared intake runners... too many things say about half that. How bout a dyno video??

I never said i was makin 700 HP.
i need the tranny to gonna try and reach that amount.
that will be my goal.

this thread is made for the 3rd gear that is broken.
don't mind if you guys stick 2 that.

thanks
 
This is what they had in stock

QUOTE=shane02pro5;3634903]I'm about to order but can someone tell me what these ratios will translate to at 6500rpm's

3.11:1@6500=36mph
1.83:1@6500=62mph
1.24:1@6500=91mph
0.90:1@6500=125 mph

or give me the formula and I will calculate it!

Thanks[/QUOTE]
 
I know, he made up all those numbers. Ha ha, you know im kidding Dana. Imagine what his car would be like if he was running his stage 2 head. ZOOM-ZOOM

Haha, I'm planning on it.

I'll probably eventually pull my current engine and sell it, and build myself a new supertrick engine. :)
