Heck yeah what a cool build. I’d love an NAT in my 2nd Gen taco.

 

I was thinking either the front mounted same side intercooler which should fit behind the crash bar, but now you have me thinking about side mounts again.
The supra or soarer side mount would probably be good, need to look up the diameter. I also saw aftermarket ones for an mr2 that is 2.5" in/out that could also work.
It's interesting because of the way the 80 is setup there is almost more space in the front lower area then in the fender area below the headlights.
I wouldn't want to flex the solid axle and have the tire hit the intercooler for sure, but once I get there I'll post some pics and do some more brainstorming.

My plan for now is to get it running as an n/a and then I'll dive into all the turbo stuff.
Ran into some brake booster clearance issues but found an interesting conversion to a Bosch I-booster unit on some hot rods to convert it to full electric.
I am leaning towards using that for this swap because its pretty new, used on teslas and accords etc.. and way simpler than the toyota Electric boosters.
Once it is in it should have plenty of assist to stop the mighty JZ in a reasonable amount of time without worrying about vacuum issues.

I was originally going to do it to a 1st gen tacoma, but I decided to just manual swap that one and leave the 5vz.
It would be sweet in a 2nd gen tacoma for sure, but I could also see a 2uz non vvti manual 2nd gen being fun too! and prolly much easier!

 

Just to update I did 2JZ NA-T AX15 swap my 80 series Land Cruiser, its called the Supra Cruiser!!
It turned out great and is a blast to drive!! Almost too quick for a land cruiser

I know I know I will buy a SC soon, I have another SC build in mind already.

I originally went with a 6262 which I considered a small turbo for a 2jz, but it felt laggy.
So I decided to downsize to a 50mm Borg SXE unit, and it hits much earlier in the power band.
Also did 10% under drive gears in the transfer case, that along with the manual gearing gives it more than enough pep to turn 35's with less displacement.



Need to take more pictures of it out in the wild but this is from a few months back getting the AC finished up.


You can check out the extra info on the mud thread I won't repost it all here but I have extra pics if anyone is curious about a specific part of it

Awesome results, Ali!! I LOVE seeing the 2JZ with a snail inside an FJ80 engine bay!

Interesting choice of going with a 50mm turbo. That vehicle needs low end response more than anything and combined with the GE cross-over manifold it sounds like you've accomplished that and then some!

And from the outside it looks like a total sleeper!

I'll be checking out your ih8mud thread with interest!

I am curious... is the transfer case up to handling the sudden power surge (shock loading) from boost in 4x4 mode? Or is this not any issue?

 

Thanks man, I figured you would get a kick out of it.

The turbo was an interesting journey to say the least, I honestly thought the 6262 was small enough to spool well.
With the stock 31" tires it was ok, and when it hit oh did it hit, it was a little crazy in the LC it really starts to scoot!!
But after going 35s it would struggle to get into boost at times so I knew I went too big.

So I started researching what is the smallest reasonable turbo I could run for spool and not choke out the motor.
Turns out alot of 7M's use upgraded turbos in the higher 40 or lower 50mm range. Then I got to thinking the 1st turbo on a 2jzgte is even smaller and those spool great, so in this case smaller is better.
I really struggled to find an example of a JZ running a 50mm or smaller turbo, which is kind of hilarious because of the internet... you know someone has probably done it.
I think I found one review of a 50mm turbo somewhere that mentioned it was great on a 2jz but that is it.

Then I looked to precision, they don't make a turbo that small in T4 and I don't want to change flange to a t3 ideally.
Borg does apparently and their turbo in those ranges is actually a hybrid t4 flange with a T3 divided opening / housing more or less.
The second smallest in that range is the Borg Warner 77257, basically a small 50mm single turbo spec wise.
I had to change the downpipe flange and angle but it was worth it to pick up that spool, and this vehicle doesn't need loads of boost it just needs it quickly .

Those transfer cases are super beefy, I would be surprised if it had any issues, honestly what would go is an axle shaft or something further down the driveline like the front or rear diff itself.
People run LS motors with bolt on's in these with the stock transfer case, they are pretty overbuilt to say the least but the 96-97 does have a clutch pack that can go bad but it can be bypassed to be equal like the older models if it fails.
The JZ comes on pretty gentle compared to the v8's so I don't think it will have any issues. Before this one I did a 2006 land cruiser manual conversion with an AX15 and the stock transfer case which is just a newer version of the 80 case and built very similarly.
Drove that one for a while really enjoying the 2uz vvti singing along with the manual and I never had any sign of any issues, in fact it drove so well I regret selling it at times lol.

I just need to get the tags updated and get some more drive time on it now. need to tweak the maps on the aem when I get some time but it starts nice and easy every time at least.
