1.2JZ? || 2JZ-GE head on a 1JZ-GTE

We get the pleasure of tuning nightworksdrifting's latest creation. This wicked S13 is powered by a 1JZ-GTE bottom end fitted with a 2JZ-GE head, dubbed the 1.2JZ. Take a look as see how it goes!

A guy in Albany Western Australia has done the 1.2jz in a JZA70 making around 700 about 5 years ago. What a cool set up it is.

[@young11984]

Good to see some different options instead of the standard 2J, cool to see some hodge podge use of factory parts to make good power

[@nightworksdrifting9708]

Awesome work lads! Still so excited to actually have it functioning and a good proof of concept it will work. Time to enjoy it and come back one day with all the goods! 💜

[@LOKISX]

Nice results! Looks like it'll be a fun different experience between your others.

[@datdom34]

Great to see some experimental engine tuning. Now its time for them to have some fun before forging her and seeing where the real fun sits on the tacko ;-)

[@nightworksdrifting9708]

Will be back one day for sure!

[@michaelhamilton7739]

cool concept brought to life. Definitely keen to hear it singing at 10k rpm!

[@zen_gaming6468]

Boost at that high of an rpm seems good shouldn’t have much lost upon changing gears

[@jonny_s14]

The only other time I've seen this done was with Aaron at drift motion. Nice video. I enjoyed it.

[@nickgrech9634]

What a rig😍

[@nightworksdrifting9708]

Appreciated my man!

[@mrsabidji]

Interesting stuff about about the GE head. Now I can sound smart and rub my stolen knowledge of it in other people's faces. Thanks. 😌
Oh and like the car, too. Would be nice to see it come back with some proper internals. 😁

[@datdom34]

True on all accounts mate.

[@nightworksdrifting9708]

For sure! Now we know the basics work it’ll be back one day with all the goods!

[@mrsabidji]

@@nightworksdrifting9708 and a little bit later I'll be here, watching a video about it, plausibly. 😌

[@datdom34]

@mrsabidji You know I'll be here watching as well mate ;-)

[@mrsabidji]

@@datdom34 But of course! We're like a big CZcams watching, RB flavoured family.

[@jaker2731]

He was correct about a GE flow in the exhaust port but GTE intake ports still flow better, not by a huge margin but better

[@Despertadohoy]

awesome, i always wondered if this combination had any draw backs besides the power band change, maybe a 264 cam and a smaller back housing would bring power in earlier. i was hyped when aaron from driftmotion did it but wasnt sure what the results were

[@JC2SLO]

Hey man! I am currently attempting to do this build for my miata lol. But more built!

[@trifeali9178]

2.1jz sounds better and looks better then 1.2jz which sounds like a small liter engine

[@urbengangster1]

What headgasket

[@urbengangster1]

But which headgasket you use? 1jz hg or 2jz hg?

[@trifeali9178]

would a 2jzgte head work on a 1jzge block? and whats needed

[@hectoralmaguer9901]

What head gasket size did you use? To get squish to oem as possible would be to use 2jzge headgasket. I am building one also currently need a headgasket option and best calculation i have found would be a thicker 2jzge one. Not a gte version as that's too thick

[@JaywithdaK]

Super interesting, is that 2jzgte valve covers on the ge head?

[@rightpricemedia8852]

Any modifications to the GE head to make this combo work?

[@tunex_]

So what do we have here for margin of durability?

[@ALP_Rhon]

I was literally building this for my gs300, car got totaled so it’s going in my supra

[@shiran_79]

Can you mate a 1jz ge vvti head to a 1jz gte vvti block?

[@mostwanted6379]

can i put a 1jz head on a 2jz ge block?

[@trifeali9178]

yes thats a 1.5jz

[@rodrigoak3761]

In Japan say 1.5jz

[@BoostGumps]

That would be 2jz bottom with 1jz head.
This is the opposite.

[@rodrigoak3761]

interesting , how many power

[@rodrigoak3761]

1.5jz

[@BoostGumps]

No. That would be a 2jz bottom with a 1jz head… this is the direct opposite

[@CJmk3supra]

5.1jz lol 😂

[@trifeali9178]

1.2jz

[@b3nny90]

Nothing new. I know a guy who has built similar with a belt procharger to make it even more interesting.

[@nightworksdrifting9708]

Interesting! Found a guy in the states currently building one, but otherwise the only example was using a GTE head. The world is a big place though

[@Mr_jz_12]

@@nightworksdrifting9708 Can;t say i'd heard of it done either.
