Learn me Toyota 1JZGTE motors...

What says the hive on the Toyota 1JZGTE JDM motor? It seems to be upstaged by it's prettier younger sister the 2JZGTE but still has good hp/trq and a strong aftermarket following. This would have come from a Soarer in Japan and arrived as a front clip/trans dropout. The interwebz tell me to watch out for ignition system and ceramic turbo components that don't like to be spun past ~14psi.

What other concerns or issues should I be looking for?

It happens to reside in an RX8 as I've been hunting swapped RX8's (various motor/trans combos) for the last year. Sadly, I have found very few that were not hack jobs or stanced to death. I also just don't have the time to take on the full project myself so looking for a 90% completed animal.

The most recent find is really clean, low miles, and has the right R154 trans. Not my first choice for drivetrain but I could do worse than low mileage turbo toyota inline 6 goodness.

Targets for the car are ~350Whp as safely and as OEM as I can make it for a daily. Gameplan is to be doing snowy donuts shortly if it pans out...

The 1jz is the driftderp's go to motor. They started tuning them a few years back because they were cheaper than the 2j but made about the same power. 350hp is doable with bolt ons and more boost. The bottom end is capable for 450hp or more stock. Change the turbo out. Stock Yota turbos aren't great. I mean, yes, the ct20 and ct26 are nice and run well, and would get you to your goal, but in the end a sexy garret or air research would be fantastic.

Good motors, r154 is stout. V160 would cost you the same as a car. Throw out the Toyota turbo like said above and get a modern garrett or borg warner/AR. The jz motors break cheap parts.

1jz is still a really good motor. I only worry about parts availability secondary to its age and popularity of the 2jz.

It does seem that turbo replacement is in it's future. Have to see what kind of used goodies are available and find some drift forums.

Hey I love drifting!

They are probably among the most popular JDM engine swaps and for good reason. As Trackmouse says it's a drifters go to motor. The cars they came in like the JZA70 and JZX90-110 are also quite good as well. People even swap them into RWD Skylines getting rid of the RB engine and other non-Toyotas.

I am considering importing a JZX90 because it has this engine and that chassis is very good.

Trackmouse mentions most of the details but the earlier engine has twin turbos, later version has vvti and single turbo. The engine is good but like with the turbos he talks about they are also not good outside of stock power. Lots of JDM cars had ceramic turbos, I think Mitsubishi is the only one to avoid them all together. These are engines you will want to go aftermarket turbo on and on the early ones probably also go aftermarket single turbo manifold as well.

350whp is an easy target on these. Single turbo manifold + GT3071R or 3076R if you want more like 400. You could go for the GTX30 turbos as well if you want even more response or are going E85.

If you want an awesome and cool daily with this power and that engine see if you can get your hands on a JZA70 Supra if you can't get that RX8 lol. Or a JZZ30 Soarer (Lexus SC).

I wouldn't be concerned any US based JDM parts site has readily available parts for them. FRSport comes to mind. No version of the RB was sold here and the only RB part I had a hard time getting was a metal head gasket (oem was readily available) but it's because I had a RB20 which nobody uses. A 1JZ is infinitely more popular in swaps so parts for them might not be autozone levels (though maybe it shares bits with the 2JZ) but they are about as common as any engine that was sold here.

A word of warning but I have been researching the JZX cars, where a lot of these 1JZs come from, and certain parts like the water pump are apparently chassis specific not just engine. The JZX has a electronic pump and the JZZ has a mechanical one like in a Skyline. There may be other differences.

One source of many on that issue: http://www.jzx100.com/forum/topic/1356-jzx90-water-pump/

I was and still am super tempted to swap one in one of my Zs.

Great help here guys. I have heard nothing but good things on these but have aponky had a non-turbo 2jz in my stable which was rock solid. Doing some homework on what oem+ Upgrades are out there. Apparently there is a cheaply rebuild and swap to the steel t12 impeller that allows you to run closer to 18psi. It seems like that 14-18 psi is the sweet spot to keep it together and reasonably rowdy.

I had my 4th gen 3SGTE turbo rebuilt at G-Pop Shop, which is about 20 miles from me. They do a lot of work for the JDM/DoRiftOh crowd.

It's been done for sure. They have been swapped into almost every rwd japanese car.

Proper turbo rebuilds at a professional shop can be very inexpensive but keep in mind a lot of these engines come twin turbo so you would need an aftermarket manifold and all that hardware to go with it if you want single. The later single turbo engine is more expensive. IDK if the costs offsets.

Will be getting a quote from a local diesel shop in town for a basic rebuild and then the t12 upgrade to run a bit more boost but stay stockish on the cheap. It sounds likee single turbo setups can be had for 1500 or so ready to bolt on but I am way early in my research to pull that trigger. It sounds like my hp goals are attainable on the oem-ish setup. As I desire a fun daily not a dyno queen that is perfect for my intentions.

Looks like there is a need to upgrade the blowoff/recirculating arrangement as the Toyota turbos have a lackluster built in setup. One would think I could simply plumb an extra one ahead of the intake no?

Checking out the car Thursday so we'll see if it follows me home.

Checking out the 1jz powered beast in the am and just grabbed the cash from the bank. Wish me luck on bringing home a new daily.
