JamieP Posted January 22, 2014 Share Posted January 22, 2014 What clutch do I use? Also what's the score with the prop fitting? And I remember something about modding the shifter to come out in the right spot? How is gearing compared to to W58? Thanks Jamie. Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted January 22, 2014 Share Posted January 22, 2014 i thought some R154's fitted directly maybe the later ones with remote shifter? Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 22, 2014 Author Share Posted January 22, 2014 i thought some R154's fitted directly maybe the later ones with remote shifter? Soarer ones fit, mk3 supra ones need the shifter modding iirc. Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted January 22, 2014 Share Posted January 22, 2014 yeah i think the chaser ones fit too, clutch wise i'd suspect you require the R154 clutch, oh and from what i've seen if you've got the box out uprating/replacing the thrust bearing would be an idea as these are known to be a weaker link Quote Link to comment Share on other sites More sharing options...
abtin90 Posted January 22, 2014 Share Posted January 22, 2014 If going down the R154 route you best option is to get one from a late model soarer. That would have the correct bellhousing and the shifter would be in the correct location. As for the prop the front of the prop should mate up to the rear of the w58 prop. Clutches all depends on your goals. Whifbitz sell spec clutches which are pretty good. Other options are ACT, carbonetics. From what I read up previously for your goals if you do decide to go single the OS Giken would be your best option. Quote Link to comment Share on other sites More sharing options...
abtin90 Posted January 22, 2014 Share Posted January 22, 2014 early soarer and mk3 boxes will both need the shifter extended - - - Updated - - - Soarer ones fit, mk3 supra ones need the shifter modding iirc. early soarer and mk3 boxes will both need the shifter extended Quote Link to comment Share on other sites More sharing options...
garethr Posted January 22, 2014 Share Posted January 22, 2014 1JZ-GTE flywheel. 1JZ-GTE or 7M-GTE clutch. There are 4 different shifters that I know of: Short extension - Mk3 Supra turbo A bit longer extension with swan-neck lever - early Soarer Cradle like the Mk4 W58 - late Soarer (and JZXs?) Even longer extension - very late JZXs First pic is early Soarer on left and Supra 2nd pic is late Soarer 3rd pic is JZX110 Quote Link to comment Share on other sites More sharing options...
garethr Posted January 22, 2014 Share Posted January 22, 2014 As far as gear ratios are concerned, I have: R154 3.250 1.955 1.310 1.000 0.753 W58 3.285 1.894 1.275 1.000 0.783 Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 22, 2014 Author Share Posted January 22, 2014 Perfect, thanks guys. The box I have is from a mk3 supra, what do I do about bell housing? Quote Link to comment Share on other sites More sharing options...
abtin90 Posted January 22, 2014 Share Posted January 22, 2014 Perfect, thanks guys. The box I have is from a mk3 supra, what do I do about bell housing? Best to put a wanted thread up on driftworks for a 1jz/2jz R154 bellhousing. Expect to pay around £300 for one. Not sure if you can get them from Toyota new still or how much they'd be. You can get copies from Thailand but not sure on the quality. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 22, 2014 Share Posted January 22, 2014 Just source a JZ to R154 bell housing, same bolt pattern on 1 and 2JZs, 7M one won't fit. Quote Link to comment Share on other sites More sharing options...
garethr Posted January 22, 2014 Share Posted January 22, 2014 (edited) You need a 1JZ bell housing. Driftmotion sell it if all else fails.

pedrosixfour Posted January 22, 2014 Share Posted January 22, 2014 Cradle like the Mk4 W58 - late Soarer (and JZXs?) Seemingly so mate. My R154 was apparently taken from a JZX90 and it came with that type of cradle. The gear stick sits a touch forward (maybe 15mm) in comparison to the W58 but hasn't posed any problem for me.

JamieP Posted January 22, 2014 Author Share Posted January 22, 2014 Damn, sounds like the bell housing is aggro, maybe better to just bite the bullet and get a 6 speed. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 22, 2014 Share Posted January 22, 2014 Getting the bell is going to be a damn sight cheaper than getting a 6 speed, Toyota still sell them and they were around 450 last time I asked. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 22, 2014 Share Posted January 22, 2014 Damn, sounds like the bell housing is aggro, maybe better to just bite the bullet and get a 6 speed. I would do that....don't start twice mate. With your 600bhp goal, I wouldn't go with R154. Quote Link to comment Share on other sites More sharing options...

If you have the funds def go for a 6 speed. As mentioned you can get the bellhousing from driftmotion for around $350 US not sure what it works out to with hsipping and taxes. They do however stock everything else needed for the conversion. You'll need the slave, prop, sensors, shifter extension if you have an mk3, clutch, flywheel.

JamieP Posted January 22, 2014 Author Share Posted January 22, 2014 I have the funds, but I'd rather keep it in the bank tbh looked at the R154 shifter extension on drift motion but they want me to send them mine so they can mod it, anywhere else that do them?

Fair enough. Good thing about the r154 is that if it ever fails they're a lot cheaper to replace. Best bet would be to pm viper and ask where he got his done. Thor racing can do them not sure how much they'll charge though. Quote Link to comment Share on other sites More sharing options...
Guest Roger NE Posted January 22, 2014 Share Posted January 22, 2014 (edited) Yes and once you have the R154 bellhousing and Shifter Extension you can always just replace the gearbox itself if it fails (mind you they're not as smooth as the W58 ! I'm talking as a Mk3 owner who has experience of both) However, another issue is the Speed Sensors - the Mk3 Supra R154 has a mechanical speedo drive cog in the bottom, and a speed sensor that is used lust for the ABS, so neither is any good for the Mk4. Presumably you have fitted a Turbo to your N/A - if so you probably want to change your Diff to lower the gearing, as changing the gearbox won't make any real difference.

JamieP Posted January 22, 2014 Author Share Posted January 22, 2014 New engine will be going in shortly, I've bought an R154 from a mk3, so need to get the rest of the bits needed, but if I find a reasonably priced V160 In the mean time I might just fit one of them.

Jamesy Posted January 22, 2014 Share Posted January 22, 2014 V160 mate future proofed for the 600hp and better to drive on motorways etc with the extra gear Quote Link to comment Share on other sites More sharing options...
buster Posted January 22, 2014 Share Posted January 22, 2014 (edited) I can get the shifter done Jamie the same guy who done mine looking at £150 plus postage pics of mine are on my build I have a spare to use as well so would be a quick exchange http://www.mkivsupra.net/vbb/showthread.php?283671-Busters-NA-T-build-with-Some-TT-bit heres the right page http://www.mkivsupra.net/vbb/showthread.php?283671-Busters-NA-T-build-with-Some-TT-bit/page8 Edited January 22, 2014 by buster (see edit history) Quote Link to comment Share on other sites More sharing options...
