script Posted August 30, 2008 Share Posted August 30, 2008 I have noticed that Auto 2JZ's can be had for nearly half the price of the 6-speed versions. I dont need six speeds. Im wondering if it is possible to pair a R154 to a 2JZ that was previously automatic. And if so how much trouble is it. Quote Link to comment Share on other sites More sharing options...
240Z_478 Posted August 30, 2008 Share Posted August 30, 2008 go to supraforums.com a quick search will give you plenty of reading material... In short though yes it is possible to do you need a R154 trans from a 1JZ or a R154 from a older supra plus a 1JZ bell housing. Quote Link to comment Share on other sites More sharing options...
RUSSJZ-ZED Posted August 31, 2008 Share Posted August 31, 2008 Have a look here as well, 1J is same conversion as 2J. http://www.jzx100.com/forum/index.php?showtopic=2012&hl=r154+swap If you start with the box out of a Chaser or Soarer with the longer shifter extension it will make your life easier than with the shorter one from a Mk3 (JDM)Supra. (The Mk4 Supra NA uses a W58 5 speed) Quote Link to comment Share on other sites More sharing options...
speeder Posted August 31, 2008 Share Posted August 31, 2008 With all the right parts it's not too much trouble at all. Like he said, R154 with a JDM 1JZ bellhousing and the correct shifter extension are required. I recently did this swap into a Lexus GS300, using a MkIII Turbo Supra flywheel and clutch. I had to fabricate the extension for the stick to come up in the right place in the GS's console. In a Z car some adapting would be required to connect the clutch slave to the Z master, but that's about it. Quote Link to comment Share on other sites More sharing options...
timbo1jz Posted August 31, 2008 Share Posted August 31, 2008 This is the clutch hose I used for my 1jz/r154 swap. I works perfectly and its cheap for a full length clutch hose. http://store.driftmotion.com/Static/Itemfulllengthclutchhose.php Quote Link to comment Share on other sites More sharing options...
Guest YoshiFD3S Posted September 1, 2008 Share Posted September 1, 2008 The reason you're finding automatic tranny 2J's is because they're coming out of the Toyota Aristo, also known as our GS300. The primary differences are the turbo's and the injectors of the Aristo 2J's, if I'm not mistaken. I'm in the process of doing a 2JZ swap into my '93 RX-7, although I've been considering scrapping those plans to do the swap in a Z instead. I'm starting to see why my brother loves his Z's so much. lol My brother's already built a 440rwhp RB25 '78 280Z, has a wide-body 240Z waiting for a motor, and a 4-door '71 510 that's having a role-cage installed to handle a beasty 500rwhp turbo KA24 motor.

script Posted September 1, 2008 Author Share Posted September 1, 2008 Are these motors still worth getting even though they are out of an Aristo? And another newb question while im at it. Has anyone with an imported 2JZ been able to do the proper modifications to pass USA emissions laws? Quote Link to comment Share on other sites More sharing options...

Has anyone with an imported 2JZ been able to do the proper modifications to pass USA emissions laws? I'll be using an Aristo 2JZ motor, myself. As soon as you go single turbo, the only real significant remaining difference between it and a Supra 2JZ, is the injectors. I think the Aristo's are like 440 and the Supra are 550? Something like that... Emissions-wise? I should THINK that with a simple catalytic converter and the right tune, it should pass. At least that's what I'm hoping. This just crossed my mind....but with all of the Z's being 30+ years old...doesn't your state waive emissions for it? lol.... Just curious??

It's been my understanding a 1JZ flywheel was necessary as the MKIII Supra flywheel wasn't quite the same. I know the clutch and disc work fine.

script Posted September 12, 2008 Author Share Posted September 12, 2008 Every once in a while I see a 2JZ with a five speed attached on ebay. So far non have specified the type of tranny. Did the 2JZ-GTE ever come with an R154? Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted September 12, 2008 Share Posted September 12, 2008 I've read over on supraforums that you can use a 2JZ flywheel with the R154. Then you can use a 2JZ clutch options. You need to do slight clearancing of the r154 bell housing tho. Justin Quote Link to comment Share on other sites More sharing options...
k1evo2 Posted January 23, 2009 Share Posted January 23, 2009 its really good to hear that a 1jz tranny can work with the 2jz engine. but does it need an adapter to fit or does it bolt directly? Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted January 24, 2009 Share Posted January 24, 2009 its really good to hear that a 1jz tranny can work with the 2jz engine. but does it need an adapter to fit or does it bolt directly?Soarer bell housing and Soarer flywheel. Actually, if you have a 5spd 1JZ tranny, then you already have what you need. Or you can use a MKIII Supra Turbo R154 and buy a 1JZ/Soarer bellhousing to mount it to the 2JZ. You can do a Google search or find all the answers to your 2JZ swap questions here; this is a hotly discussed topic on any 2JZ site. You're going to get a lot of your posts deleted or sent to the Tool Shed, fyi - more searching and reading.... less posting. Quote Link to comment Share on other sites More sharing options...

I thought it did. Speeder said he used the 7MGTE flywheel, but I believe he misspoke - the 7M's crank bolt-pattern is 6 holes, not the 8 of the 2JZ's. I imagine he did what I plan to do - get a non-turbo 2JZ flywheel and have the pressure-plate-to-flywheel bolt pattern matched to my 7M pressure plate I already have. 7M flywheel (aftermarket, I suppose) 2JZ flywheel (aftermarket, though) Regarding shifter extensions, some people are okay with how far forward the shifter is in the hole and some people don't want their engines all the way up against the firewall. There is/was a factory extension that cost $80 total to have your shifter come out about 1.5" further back than a stock Supra R154. I'll just wait and see where mine ends up and decide what to do. At most, I imagine I could be wanting 2" further back than what I'll end up with. Quote Link to comment Share on other sites More sharing options...
Overkill Z Posted January 26, 2009 Share Posted January 26, 2009 i would think that would work...but why go through the time of gettn the holes matched when a 1jz flywheel bolts right up? or did i miss read u? Quote Link to comment Share on other sites More sharing options...

Let's say my numbers are a bit off and it comes out to $150 - I'm still more than $100 LESS than the cost of a new, OEM 1JZ flywheel. I've been having to pinch pennies lately and this is one more way to do it. Quote Link to comment Share on other sites More sharing options...
