the final word on getting an r154 (ijz manual) box into a ma61 supra
|

ok, it's getting close to crunch time now... I need to figure out if I'm going to use the w58 box of the ma61, or cram the r154 in there behind the engine.
Obviously the r154 would be preferable... all the goodies are already there, plus it's stronger.
what I need to know for sure is, how hard is it to fit? I've heard some people say it's impossible and dont bother, others say it's fairly wasy to fit, as long as you're willing to do a little bit of "persuading" to the tranny tunnel.
does anyone have a definite answer for me?

when i was going to get a new engine for my mk2 supra i was told by basically all the engine jap importers that the standard 5spd gearbox will handle that power.
i reckon. save your money and if need be get it later.
not much of an answer, but i hope it helps anyway.

Personally, I reckon if you don't go stupid with the power, and you drive hard, but aren't mean on your car, the W58 should hold up.
Installing the R154 has a lot of problems. Its wide, the shifter is right back, its heavy. It would take a fair bit of work to make it fit. Better to just see how the W58 goes, if you really want to try it down the track give it a go...

yeah.. but I'm wondering if it's better to bite the bullet now and fork out for the tranny conversion.
'cause otherwise I have to buy a 1jz front cut, AND all the 2jz-GE stuff to get the w58 to bolt on

I reckon you'll have to cut-and-shut the trans tunnel to do the job properly. What are your metal fab skills like? If the answer is "what skills?", get a quote from a body shop and then make your decision.
You might want to ask this question on the Mk2 Supra mailing list, as I think there are some people there who have installed R154's behind 7M-GTE's.

wait till i hvae to get that bloddy getrag into the 2jz project car 
anyway, on topic: how hard to intend to drive the car, and are you going to use a harsh clutch etc? if te answer is 'softly' and 'no' then just get a w58, rebuild it so you know its all good, and worry about a r154 if the need ever arrises

How much bigger is the Getrag that the R154? And where does the shifter come up? Does Nishad have a V160 or V161?

well, I plan on using a full-face clutch. maybe later on a kevlar coated, or perhaps a 6-button ... but no 3 buttons or anyhting like that.
and.. well anyone who's seen me drive knows I drive hard. not so much abusive on the car, though there will be a few hard launches in there.. but I enjoy driving, and I drive well (read: hard and fast .. connotations welcome)
I tried signing up on the supra forum, but it kept fuggering up for me :\
and my metal fabs skills are.. well, above the average know-nothing, but they're not fantastic

hard launches are one thing, then theres hard shifting. do you like to slam gears and shake the ground at each gear change??
ultimately, the r154 is the better box, but at what cost, and are you prepared to not be a cockhead with clutch at the expense of getting away with a w58?
tranny tunnel swap is a HUGE MOFO PITA!!!!

I'm wondering what the price range would be though.
because for the bellhousing, clutch, flywheel etc to mate with the w58, I'd be up for close to $1000
I'm sure a metalworking shop somewhere would take on the modifying for aroun that price

now there's someone with a brain. I knew I should have gone to school longer.
anyone recommend any places, or types of places?
I was thinking if I could get the specs of the r154, and give the parts to a metalworking place, they'd charge me a shit,oad less than finding a "car re-designing specialist" ....
but any names of places would be appreciated.
I have too many phone calls to make tomorrow

I'm not ed, but both. The shifter on the R154 comes a little way back, and the box wont fit physically without making the tunnel wider (ie. belting out some of the ribs = dodgy or cutting it out, making it bigger = $$)

by "belt out", you mean just hit them till they get wider?
I guess I'll have a better idea what I'm in for once I actually have a look at the tranny tunnel
and since the stick will soit a little further back, I'm guessing that means cutting it a new hole.

I mean, there are strengthening ribs in the tranny tunnel. You line up a plank of wood on it, and go to work on them with a sledgehammer to "releive" the tight spots. Effective, yes. Dodgy, also yes.

FWIW the shifter on my 2JZ-GE transmission was about 5-6 inches further back than the original Mk2 transmission. That should give you an idea of where the R154 shifter is going to end up... I hope you've got a flexible left arm!

Havn't read all the threads, but you can move the shifter forward if the R154 box is off a 1JZ Soarer. The back section unbolts and you swap it with a MK3 Supra rear. (Note sure if it matters whether the Supra MK3 rear can be off a W58, but i'm sure the R154 will work.) Just need to locate one.

but I figure if I get a short shifter for it, it's probably better it sits a little way back
maybe not that whole 6 inches... but a little way
6 inches... did that get in the way of the handbrake?
and since I've never heard of a tranny tunnel failing, I think I might go to town on those ribs...

MK3 - try www.supras.com, then you can get on the list - there are directions there somewhere. They never used to have a Forum, just an Email list. 1 hundred emails a day, so suggest you register in the way so you get them all rolled into about 4 per day.
MK4 - try www.mkiv.com, I think they operate similarly.
I've had a Supra for 11-12 years and thought about a 1JZ conversion, so I looked into it a while ago.

getting in the way of the tems buttons wouldn't be such a hassle.
where would I get my hands on a short box?
because if needed, I can just not get a chaser front cut, get a soarer one and just buy a chaser sump (although I'd prefer to stay away from the soarer hydraulic water pump)

A MK3 Supra R154 box is the shorter box. Or you can get a Soarer Long R154 and swap the long extension with a short one. As I said before I thing a short off a w58 may even fit. I think Dellows can do the swap for you.
Out of interest, whats the problem with the Soarer hydraulic water pump? As I have one. Would be nice to know.
