Before you do a 2JZ swap..

[Manji]

I keep seeing 2jz swaps coming up on my news feed, and don't get me wrong I think that's great, but really surprised more aren't going 1uz TT.

2jz's come with a manual box, and factory turbo, 1uz's don't have either. But the aftermarket has shown these to not be issues.

You can buy bellhousing conversion kits to bolt the good toyota manual boxes to a 1uz.
The early generation 1uz's (non vvti) have proven time and time again to reliably take 600hp+ unopened, twice that if built.

1uz pros over 2jz
1000cc more displacement
75kg lighter
Cheaper
Shorter

Depending on your plans with the 1uz, governs which gen you buy. The early gen model (non vvti) have a stronger bottom end. If you don't want to build them, and just use stock motors, get an early gen.

If you're going to build it, get the vvti model. It has a far better head, but the rods are weaker.

So, why don't more people put 1uz's and twin turbo them, compared with 2j swaps, in other platforms? The 1uz is a big bitch. But again, remember it's quite a bit lighter than a 2jz. It's because there isn't the room. A lot of cars barely have room the 1uz itself, and need horrible "block hugger" headers to fit in, certainly not enough room for turbos.

BUT, the beauty of the gt86 is that it has a boxer. So the engine bay is very wide. Easily wide enough for a 1uz and a gtx28 or gtx30 either side of it.

1uz turbo setups are becoming more and more popular in the drift scene over here. Because of the reasons above, strong but still cheap. But the ones I've seen are in silvias, and because their bay isn't wide enough for TT, they have to do this ugly 8 into 1 setup with the turbo forward of the motor.

Here's a front on shot of my car. Look at the room we had for the headers. Easily enough room for a pair of snails.

Someone do it!

Hi,
im wondering why nobody is looking for a 2GR swap. This engine got so much potential and is even smaller than a V8 an lighter of course.

[nguyen_er]

Do you have a build thread?

[slicktop]

The matter of 2JZ vs 1UZ is preference.

Both capable engines. I like how my 2JZ has more room than the 1UZ.

big ups for a solid first look at the benefits and feasibility of the 1uz, able to be followed easily and arguments non-emotional, straight perspective

i applaud anyone that has the guts to do an engine swap on one of these cars. Pulling a brand new motor is insane

I want to do a 1uz swap eventually. If you could post as many pictures as possible. This swap looks really good.

2GRs are not THAT great. They are too tall to fit in the engine bay, mostly because the complicated 3 stage VVTi head, they are not that light either.
Although dual-vvti, they don´t like to rev too high, and suffer from mysterious VVTi-gear knock, that nobody can fix ..just have to live with it.
I´ve got one in my Aurion (AUS Camry) and another in pieces lying around the garage
As for fitment, better look for the older (and simpler) 3MZ-FE..

More pics!!

If this motor had more parts to easily convert to rwd, I would be all over for my te72. Everything I have seen is it is a pain to convert(relocating starter, adapter plate for trans, etc).

The issue with the 1UZ has always been lack of performance parts. They're great if you're a fabricator or can afford to have that stuff custom done...


In the Supra world it's kinda laughed at because it's a whole lot of hassle for only 1.0 liter difference. Same amount of work, better aftermarket support, and more engine bay room with an LS motor


Waiting for someone to toss a 3UR in one of these cars... but again, expensive...

A majority of these guys are purchasing their BRZ/FRS chassis from salvage auctions. I seriously doubt they are purchasing brand new or slightly used donors for their project.

I love the 2gr series engines however the 2gr-fse is too tall a custom intake manifold needs to be created

as seen here


Tom's did it!





Some one used a 3gr-fse again a custom manifold must be created

This.

I wouldn't even contemplate it until my motors sees close to 100,000 miles.
