BLKMGK Posted July 26, 2003 Share Posted July 26, 2003 6spd not going to work, page on my site in th epics section has info on a 1JZ swap which woudl be much the same. Skip the goofy trans adapter they did and use the 5spd from an N/A GE car. Sick power can be had from the 2JZ with simple bolt-ons. Mine dynoed 582RWHP on pump 2 days ago Quote Link to comment Share on other sites More sharing options...
kalium99 Posted July 27, 2003 Share Posted July 27, 2003 Why wont the 6spd fit? Is it too big for the 240z tunnel? I've got an Auto 260z and IIRC the tunnel is a little bigger in them... Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 27, 2003 Share Posted July 27, 2003 Tunnel is the same size - they didn't mske but one floor pan The 6speed is too long to fit. I believe this is detainled in th earticle I mentioned earlier - have you read it? Quote Link to comment Share on other sites More sharing options...
kalium99 Posted July 28, 2003 Share Posted July 28, 2003 I havent read it complete in a long time....since it was published. Anything will fit if you have enough money. Quote Link to comment Share on other sites More sharing options...
fl327 Posted July 28, 2003 Share Posted July 28, 2003 Im sure you could make the six speed fit, its a getrag unit, its almost invincible, and worth the mods to make it work. ive heard a vicious rumor from my importer that the jdm 2jz makes less hp than the american version, but the engine is still a work of art and would still rock pretty hard in a z. my buddy dynoed one with 130k on it, sucker made 300hp with stock everything, and a dirty air box!!!! no joke im tellin ya, no joke. in a z it would get 27mpg or something stupid like that, and purr like a kitten at idle, giving nobody any clue as to whats coming for them. its right on par with an rb26 in terms of hp stock, but to me has an advantage over the rb in that it was offered domestically, but hands down, popping the hood of a 30 year old car and seeing an engine that you cant even legally have in the US and being Nissan is a plus, but the added practicality of the 2jz is another factor to ponder within itself. oh yikes, forgot about the swap easiness or lack of. if you use a standalone, firing the engine shouldnt be that bad, mounting the engine shouldnt be that bad either since the turbos are on the passenger side, i do like the idea of using the stock harness and then using one of those aem units to run bigger injectors and be able to program the sucker, 582hp on pump is just sick!!! from ANY motor. RB i suspect is a little easier to wire up, if it resembles anything like the sr20det swap, ill rock that sucker. Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 28, 2003 Share Posted July 28, 2003 As I said - the 6speed is too long, you cannot simply wish and make it shorter. Nor can you easily move the engine forward - it's a straight six like the L6 and fairly long. The 5spd will hold fine in a lightweight Z although the 6spd gearing is VERY nice. If you want it to shift at your elbow perhaps that would work fine. READ the article I mentioned, I believe it details this. If I get a chance I'll measure my trans length. Oh - 6spd Getrag Supra trannies retail around $2K. Yes, the JDM motors make less horsepower. The have smaller injectors, smaller turbos, and the engine management is different. Since to make power you must swap the injectors and the stock twins will NOT fit in the Z engine bay this is no big deal. Wiring up an AEM to run this motor wouldn't be hard - I'd use the Honda 1010 box to do it and load a Supra mapping in it. Don't know how hard it would be to mount, one day I hope to find out Quote Link to comment Share on other sites More sharing options...
fl327 Posted July 28, 2003 Share Posted July 28, 2003 i thought the regular six speed tt box was a getrag unit? sucks about the six speed being a little long, me being me i would have to have it and would rig something up to use it. yes i read the article blkmgk- do you have any idea why the tt in jspec mode make less power than the aspec? thats cool the only tt 2jz swap ive seen, that one on ebay a while back, had a custom manifold i guess it was neccessary. the fastest street cars ive ever seen are tt supras with a big single turbo, i mean like a bullet type ridiculous fast, which is nuts since the car is pretty big for an import. yup-with the options available with the piggyback systems and what not, if i were to attempt a swap like this i would use the factory harness and run the aem, its outrageous the rwhp figures im seeing from these engines. alas, if this venture im getting into right now works out, a toyota engine wouldnt be right, since the newest fad is the Nissan engines, ill be "stuck" with the RB series, oh poo Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 28, 2003 Share Posted July 28, 2003 They make less power due to the turbos being smaller, the cams may also be slightly different. Their engine management was MAP based instead of MAF. This was all likely done to honor the "Gentleman's Agreement" on HP in the JDM market. Not sure what the Euro Supras had but it was either the JDM spec or the US spec stuff - lots of JDM Supras in OZ and Europe so who knows. The 6spd is a Getrag, it's also about $2K if you can find one in decent shape. Not sure why the 5spd would be shorter since it and the 6spd both fit into the same chassis just fine - maybe there's a bellhousing difference? Given a choice I'd want the 6spd but only if I was sure it would fit. The 1JZ would also be an interesting swap but the turbo setup is a PITA on that car compared to the 2JZ if it would even fit. Don't know if an off the shelf turbo kit would work in the Z chassis - I'd hope so. Not ever measured mine but it's further forward and further out to the side than the OEM turbos I think... I wouldn't do piggyback electronics. I'd wire up the AEM with the Toyota harness if I could get one cheaply. Since it's a swap anyway I'd use the cheaper Honda AEM with the Honda connector swapped onto the OEM harness since it'll likely need to be hacked up anyway. If I couldn't get a harness I'd be stuck making one but really that's not too bad I think since there are only a few connectors and Toyota probably sells them all.

kalium99 Posted July 29, 2003 Share Posted July 29, 2003 As I said - the 6speed is too long, you cannot simply wish and make it shorter What was 'Zupra' running? For RHD cars I dont think there would be too many problems with fitting a 2JZ, my 1JZ will fit without too many hassles, but as you say the turbos would provide the most problems Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted July 30, 2003 Share Posted July 30, 2003 If you mean the Z that the Options mag swapped a 1JZ into I think that was the N/A 5speed... Quote Link to comment Share on other sites More sharing options...
kalium99 Posted August 9, 2003 Share Posted August 9, 2003 If you mean the Z that the Options mag swapped a 1JZ into I think that was the N/A 5speed... Not sure about the zed in an option mag that you are referring to. I meant the one that was for sale on Ebay quite some time ago, I believe it was you (or possibly someone else) who sent me pictures of it. It had a 2JZ in it. Just cant remember the box that it ran.

BLKMGK Posted August 9, 2003 Share Posted August 9, 2003 Still have those pics somewhere too but I also don't recall what trans it was running Quote Link to comment Share on other sites More sharing options...
