1jz-gtte

[*D-Joker*]

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.
