thomo8568 Posted December 30, 2014 Share Posted December 30, 2014 Have a look here. http://wilbo666.pbworks.com/w/page/47216384/1JZ-GTE%20JZZ30%20Soarer And here http://wilbo666.pbworks.com/w/page/41678224/2JZ-GE%20JZA80%20Supra%20Engine%20Wiring Print out the parts for the body loom plugs and work out which wires go where. I've got my paper work I can send you a copy of if you PM me your email. There are a few incorrect wires listed so will need checking over. But 90% right. Couldn't say anything about the manual gearbox stuff as I'm using the auto box. Quote Link to comment Share on other sites More sharing options...
DodgyRog Posted December 30, 2014 Share Posted December 30, 2014 Contact little num here on the forum, he has done the conversion a few times http://www.mkivsupra.net/vbb/member.php?15118-little-num Quote Link to comment Share on other sites More sharing options...

Kendo11 Posted January 2, 2015 Share Posted January 2, 2015 To sound like a bit of a noob, what's the advantages/reasons for going 1jz rather than the 2jz gte? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted January 2, 2015 Share Posted January 2, 2015 To sound like a bit of a noob, what's the advantages/reasons for going 1jz rather than the 2jz gte? Sweeter little engine, happier to rev as it's a square engine (stroke length equal to bore diameter). But for most the main reason is probably the price difference.

pedrosixfour Posted January 2, 2015 Share Posted January 2, 2015 If you can do the spanner work & wiring yourself then the 1JZ swap is effectively half the cost of a 2JZ(TT) swap. Throw in a few parts to get you to BPU and you are doubling the power of your NA Supra for about £1000-£1200. Don't think there is a cheaper route for the gain to be honest.

Luxluc Posted January 9, 2015 Share Posted January 9, 2015 Littlenum has a great setup on his 1JZ .. 650+bhp iirc. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 9, 2015 Share Posted January 9, 2015 If you don't need the ultimate power and torque the stroked 3 litre 2JZ has, and like a turbine smooth, ultra sweet straight six, they are great engines. the wife's old Soarer just sounded gorgeous, and was so smooth it was a delight to drive.The 3 litre is a bit of a rough diamond in comparison. I think they are a fabulous engine, and as people have mentioned, they are much cheaper to buy. Quote Link to comment Share on other sites More sharing options...

bignum Posted January 9, 2015 Share Posted January 9, 2015 Chris would you say they have the same kind of unearthly famed bulletproofness that the 2jz has? Unfortunately they don`t, possibly as they rev higher than the 2j the shells tend to fall out with anything above bpu power. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 9, 2015 Share Posted January 9, 2015 I have little experience of tuning them, so can't really comment, but I can't see any reason why they should be less robust. When you say the "shells tend to fall out" what exactly do you mean? Which shells? have you a photo or two of some? Shells don't just "fall out" Quote Link to comment Share on other sites More sharing options...
bignum Posted January 9, 2015 Share Posted January 9, 2015 Mains knocking, spun bearing, my bro will have photos i`m sure. so ok the crank falls out then, Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted January 9, 2015 Share Posted January 9, 2015 There doesn't seem to be much point revving the absolute nuts off a stock engine running BPU though, the power seems to teeter off fairly rapidly after about 6.5k rpm, a combination of stock turbos running more boost than originally designed for and stock cams restricting breathing even further. I'll be addressing at least one of those restrictions in the very near future myself with a set of 264 cams & vernier pulleys but I might just tune the engine to improve the midrange as much as possible as opposed to all-out top end as I think it'll suit my needs better and will allow the stock turbos to work in a range that suits their characteristics/limitations. Of course if the stock twins get the big heave-ho for a single sooner or later (please, please, PLEASE be later) I'll have to rethink all that and would probably pull the engine to upgrade the shells to take more revs. Quote Link to comment Share on other sites More sharing options...

But for most the main reason is probably the price difference.It's also a lot less "torquey" than the 2JZ, so it should be correspondingly less likely to muller a W58.
