Although it makes sense to mill the housing, it'd be nice to have conclusive information regarding clutch disc spline engagement along with the pilot bearing engagement.

I guess we'd need the bellhousing length along with the input shaft length and the position of the splines..

 

well quick was just mentioning in the crank walk thread if you machine the bell housing the dowell pins are gone which is not good, so I guess the solution isnt that simple although he did say about using a twin disc clutch, maybe that solves both problems in one?

 

Just posted in the other thread, but why would machining omit the dowel pins?
If it does, why not just drill into where the original pin was, and replace it with a universal?

 

Good pic of the bell housing removed, I didn't realize it came apart that easy.

Incorrect assumption on the rotational mass increasing, mine was decreased from the stock setup.

 

if the trans is bolted up why/how would it flex or move just because you dont have dowel pins?

 

Stock AUTO or 5spd?
I assume auto.. which seems pretty obvious since the tq converter is one heavy **** at nearly 40#.

 

I guess it depends on the flywheel used, you could be right about the weight but the problem for me is spacing any weight further away from the crank, doesn't seem right to me but I understand it works.

I think its more of a getting it aligned up perfectly before bolting it down rather than it moving around afterwards.

 

Has anyone had any success with buying a transmission with grinding issues and replacing the synchros?


there are some really cheap broken ones to be had.

 

Just giving you a hard time. I'm using a lighter weight JWT flywheel which is why overall mass is reduced slightly from my stock 5spd setup. I completely agree it is not ideal having the weight away from the crank, but I like that I can use any off the shelf flywheel clutch setup vs. a custom setup only available from 1 person. When I was doing this I didn't realize anyone was milling the housings keeping mass closer. Good to see newer better ideas/routes being tried here. The goal of me sharing as many pics and info as possible was to share what I experienced, get people talking, get new ideas and hope for improvement. Not to say my way is the way, but just get it all started.

 

Someone with a r154 currently in there sc please tell me the measurement of the bellhousing to the center of the shift. I may have just found a solution to all of our shifter placement troubles.

 

I know these measurements are for a W58 but I think they're what you're looking for since that was the stock trans in our cars.
26 7/8" early non-tripod W58
30 7/8" tripod W58

I found these measurements here: http://www.supraforums.com/forum/sho...rement-for-W58
And here I have found mention that the SC tripod is 1/2" shorter than the Supra's tripod that is measured above:

Hope this helps.

 

Will both w58 fit in the sc300

 

Back to Topic guys...

 

This is on topic read my post. I just said I may have solved the shifter length issue for the cd009. I needed measurements to make sure I get it right.

 

But all you have to do is cut the tripod bracket and shorten it?? That's what couple guys have done.
