Default 2jz swap

i know there is some RWD subbies running around, and i have a buddy with a 89 supra and he has been talkin about wanting to drop in a 2jz motor.(his current motor is NA) so i started thinkin...has anyone else thought about if a 2jz supra motor could be made to fit into a subbie??

i think this would be a awesome ride, but a lot of work if could be done at all. the motors and 6mt trans can be had for about 5K on ebay...

what do yall think?

EZ30/EG33 if you want a 6cyl.

RB and 2JZ won't fit without cutting the rad core support and moving it a foot!

measure twice and cut once!(if you got the cash to finish it!)

The 2JZ motor is over 3x longer than a EJ series motor.

With enough time and money, it could probably be done. I haven't seen a 2jz in a wrx yet though (only other "generic" swaps like the csb).

Anything can be done with the time and money.

I just feel the weight distribution would be terrible.

You'd be running raked. Look at the Supra; it's very long and can distribute the weight very evenly.

There are RWD subarus here on the boards.

2jz swap just sounds like a dumb idea. Not in a omg it'll be cool cause no one has done it before and it's differet!!1!!1!
.....Just flat out dumb.

It would be a great swap, It wouldnt really cost much more then a full STI swap

Im going RWD to get rid of some stress, Then changing the gears to get some speed. The 2JZ is a bad azz up top motor.

well if you can do fab work and dont mind havin to do electrical work i wouldnt be surprised. go to ebay ive seen plenty of 2jz motors and trans for 5-6k...

i do agree that it is a stupid idea to some extent but id guess most mods that are unique are stupid in atleast someones eyes... theres always someone pushing the envelope for swaps, mods, etc....jus a thought

Which is by far shorter in every way. The 2jz is way longer than the engine bay so you would have to cut into the firewall at least. It is also a tall motor so you will have all sorts of fun clearance issues to figure out.

Unless it is a gutted, soul use drag car then I don't really see the point when subaru has plenty of 500-700whp options. If you need more a ls6 twin turbo should do the trick.

theres 2 more cylinders to fit in there!!! it's not going to fit without lengthening the nose and moving the core support.

it's not going to fit and still look like a subaru. it may fit in a newer legacy, but it's a waste of $$ to try it as they already come in them!

I was implying that the sr20 is the better option. No need to flex your internet knowledge.

not flexin fool!

it's just a waste. theres really nothing to gain. it's not like SR's make silly power(RB's or 2JZ's). your not gaining HP or displacement(maybe off line TQ), center of gravity goes up, handling goes down, etc...

you can RWD any subaru with OEM parts. no need to strip a 240sx/180sx of it's heritage!

<------240sx lo0ver @ heart. i still own a pristine white one(project).

I haven't read through the entire post, but I am actually in the middle of doing a 2JZ swap in my bugeye right now. Motor and trans have both been test fit already, no major cutting or firewall modification necessary

Once I have more pictures I'll start up a build thread for all the non believers.

OH, as far as cost goes, if I stick to budget, I'll be in the swap about $1500 less than a USDM STI swap (motor, tranny, brakes, etc), as I'm doing 90% of the work myself.
