1jz-gtte
 

I have a 7mgte engine in my supra now and its blown. I am going to swap it to a 1jz engine and was wondering if my tranny from the 7m would fit on the 1jz engine ??? If not what are the possibilites i could do without having to buy a tranny???? Help PLEASE!!!!

hey mate.
i want to do a 2jz conversion, and i asked if i could use the 7m gearbox.
and one answer i got was that it could work if i used a 1jz bell-housing.

so from that answer im guessin that a 7m box will fit up 2 a 1jz, im just not sure about the shaft length inside the boxes...if they are all the same or not.

I have an 89 supra and want to put a 1jz twin turbo in it and was wonderin if any body knew the best thing to do for the ECU and wiren harness cas i aint sur how different the 1jz and 7m are

I'll answer both questions on this thread from my experience with a 1j swap.

The 7m trans will fit on a 1jz, only if first, you have a 1jz bell-houseing, and second, if you have the R-154 transmission. the W-58 won't match up to the 1j bell-housing.

Evant: As for wiring and such, because the 1jz uses individual coil packs, you'll need to either use a 1jz wire harness and ecu, and convert it for the ma70 chassis, or use a 2jz wireharness and ecu, which is a lot more work to convert to work in a ma70 chassis. The 1j harness is usually easier, though you have to extend it about 3 feet due to differences in the Japanese and USDM car's.

Have fun with that.

thanks man thats helps alot. it sounds like you hav don this swap or somthing similar?

Yeah, I've done a 1j swap into my 87. The biggest mistake I made was ordering my engine from Tiger Direct. Biggest ripoff artists ever, and it was such a headache getting all the parts I needed.

I think Tiger Direct could be the same place I was thinking of buying from
is this them? http://www.tigerjapanese.com/index.p...hk=1&Itemid=26
either way I have another question
would the turbos come with the engine and if this is the same place what kind of troubles did you have?
i was also wondering if I should just go for a 2jz but I can't even find one for a Supra on the site

My story with tiger is long and boring, but in short, i was missing parts and it looked like my motor had come from a junkyard and parts were pulled from different engines to make mine. and expensive stuff was still missing, (ecu, wire harness, flywheel.)

My advice, find a reputable company that you can get a BBS report on, and make sure all of the major stuff you may need, (ECU, harness, turbos) you can replace easily with either custom made parts or aftermarket parts.

As for the 2jz. in the end, the only thing that makes that swap so hard is that the ecu wiring is majorly different from the 1jz swap. Essentially, if you're computer savvy, it really shouldn't be that hard, unless you're trying to use the 6 speed V-160, then hoorah for you, i wish u luck.

Feel free to ask any other questions if you do the 1j swap, it's a great engine really, with plently of US parts support if you know where to look.

do you know any other sites?
it is very tempting to just use Tiger as it seems so easy
something sketchy I found though was that I searched for a 1jz and I got a Tiger site with almost the same lay out and almost identical names
one is jdmtigerjapanese and the other is just tigerjapanese
kinda seems like one of them could be fake
do you know which one you used?
I really wish I could just get some positive feedback for this site. lol

and to ramble on I would just like to ask whether this is a good idea or not.
I am not the most experienced mechanic. I am still in school and this is my first car but I want to do the swap.
so I thought it may be a good idea if I drop the engine myself and then tow it to a shop and get them to do all the connections like wiring and stuff
the last thing I want to do is screw up my Supra
I haven't even gotten as far as finding a shop that would do this

btw here are some links to the sites if you wanna check it out:

sorry if im a lil off topic here but i just bought a 87 supra shell (no engine) i would like to know what is the best engine to put in? i was thinking the 1jgtz but what would be the requirements? is the wiring the same, would i need a intercooler, etc.. first time working with toyota.. did plenty of engine swaps on hondas never on toyota tho.. seems kinda tough but i can work it out with some help plz.. thanx guys!! :wavey:

Well 87TT, to be honest, it's a lot of work to drop in the 1jz. sure you can do it on your own with the right tools and some research, but the wiring is something you don't want to screw up, and the shop you take it to needs to have some knowledge on the 1jz, since it was only made in japan the wiring diagram isn't easy to come by, so you might be out of luck on that. As for the site, I believe both of those are actually the same site for the same company (confusing huh?) but as for finding a different site to help you out, i can't think of any off the top of my head. Try a google search really, or even ebay, i'd trust that more than tiger.

And to answer you suprakidd, it's really about what you want to do with the car. 7mge, 7mgte, 3g, 1jz, 1uz, 2jz, there are a lot of motors that can go in the MKIII that all have there merrits. 7m's are drop in engines as those are the stock engines. And the 1jz has about 3-4 plugs under the dash that need to be re-wired so the engine will run, along with another 1-2 under the hood. The others i have no clue, but you have options. Granted, you can use the 1jz head and wiring, and use a 2jz block as well, making it a 3 liter with a great flowing head, (i wanna do this eventually), but like i said, your options vary.

thanx man. lets say for example if i wanna do the 1jz swap which plugs would i have to switch or whateva? i was looking at the 7mgte is it a drop in engine? no custom mounts? welding? cutting? etc? would i have to buy an intercooler for the turbo on the 7mgte? so for sooooo many questions.. thanx happy holidays.. :wavey:

The 1jz has 3-4 plugs that branch off from the main harness and plug into the dashboard harness. Because it's a JDM made harness, the plugs don't match, so you have to change the JDM plugs to match the USDM dash harness. Also, the plug that goes to the fuse box under the hood needs to be changed as well. (This swap isn't that hard as long as you have everything you need. Just time consuming.)

The 7mgte is a drop in motor for the mkIII, with no changes to the wire harness or mounts, as this motor came with the car. just depending on which year your supra is, you'll have to use different mounts. Pre 89' years use an old style mount. 89+ year supra's use a newer mount because of a subframe change. And yes, you'll need a stock intercooler, (or aftermarket) if you use the 7mgte motor, turbo ya kno?

Of course, there may be other subtle things I dont' kno about the 7mgte that i don't know, as i haven't worked on that engine (I'm mainly a 1jz guy), so make sure to ask around and get a good idea of what you're doing before you start.
