Any active 2JZ swap build threads?
 

As the title suggests, does anyone know of any active 2JZ swap build threads?

I'm interested in doing the conversion and was hoping to follow anyone that's currently in the process or has successfully completed the swap. Very interested to know what is actually involved and or what the challenges are.

I found a great build thread which was extremely informative, however it hasn't been updated since May. Here...

Thanks in advance.

Same here. Can't decide between building up the FA20 or a 2JZ swap. That forum that hasn't been updated since May usually means something has gone wrong. Best bet is to wait on a full swap kit. Only swap kit I know that's out for our cars at the moment is a LS2 swap kit. Just have to wait and see..

It's not that hard to put a motor into anything, if it fits. The good thing we have is an engine bay that currently has a boxer in it.

It all comes down to whether you want to street it. Which in my mind answers itself. If you're thinking 2jz, your thinking more than 500hp, as otherwise you're better sticking with the fa20. So if it's that much power, it's not a street car.

You're looking at basically changing everything mechanical. Entire driveline, entire brakes/suspension/cooling/fuel system. The only thing you're using from the 86 is the shell, seriously. $30k is a lot of money to spend on a shell.

IMO, the only reason to do a 2JZ swap is so you can say "OMG I HAVE A 2JZ". They're HEAVY iron block engines, and for WAY less than the swap will cost you could have a built FA20 making just as much power. Unless you're aiming for 1000hp + there's no need to go with a different engine.

Planning to do it sometime next year. ;)

Lol , you need 25k for a 2j swap and you can push 600whp on pump all day and 800on e85 all day everyday, good luck doing that with a fa20 engine, and no its not only OMG i have a 2j thing, people use them cause they work and have a solid background on them. Ekanoos 2j gt86 was corner balanced and showed every boxter fan boy that it did not screw up balance as much people talk about.
flame suit on
To answer OP , you are looking at anything from 25 to 35K. I asked 2 people who did the swap and thats the price range they told me. I also went to the best supra/fabbin shop and thats the price i got expect that they gave me a very very long down time.



You can pm me if you would like more information

Corner balanced is one thing. What about cog?

That will obviously be altered

Any active 2JZ swap build threads?
 

For the people worried about the "balance" thats a big thing.

Swaps are fine, i understand them, i had a mk3 w 2jz swap myself (not a car altering swap like some swaps tho) but when u start w a really good car, there is going to be a trade off at some point, in this case seems limited to cog and price/work. As stated, unless the person needs over 500hp it does not make sense $ wise at that price (though im sure the swap can be done for less than 25k, unless that price includes ALOT of 2jz upgrades and the v160/161)

A 2jz + v160 about 8grand in clean and immaculate condition as the 160s hate to be rebuilt
Modifying the tranny mounts
A proper fuel system 3k
A standalone can be 2k , custom harness , and incorporating the supras ecu and the 86s (total of 3) can be costly
Custom radiator
Custom intercooler
Custom driveshaft from dds 1.xk
Extensive modification to the steering rack
Single turbo swap (done properly and maybe a custom manifold )

Labour

Right. Like i said. Including a v160 and upgrades beyond "just the swap". Putting in a base 2jzgte w a diff tranny option could be done for under 10k. But like i also said, why do a 2jz if under 500hp, or even under 700

After a few years when the car is old enough to need emissions, will it pass?

It depends how you build it really but I don't think the Supra was even OBD-II, was it? You would have to hack something together using the existing BRZ ECU.

I'd probably do a LSx swap way before a 2JZ swap unless you truly want to build a large HP turbo car.

True, i plan on boosting my block on e85 and see how long it lasts and then maybe swap , im also hopefully getting a supra soon, which might tame my 2j cravings (doubt it)

I don't know about all of that. As a guy with a 1JZGTE Soarer and an FR-S ... the 1JZ/2JZ is a much more stout engine with a massive knowledge-base. It's already proven to be much more reliable and is far easier to service many parts on.

Associated driveline parts with a 2JZ are also going to be more available and are reasonably bullet proof.

The FA20 has been such a let down for me. The factory drivetrain isn't really made for a lot of power. The engine itself is plagued with growing cases of DI failures. It's DI and high-compression. A lot of people really don't like playing around with unforgiving setups like this.

The FA20 .. I will call a successor to the NA EJ25 .. but it's not in the same league as a JZ engine. I don't think a 1JZ/2JZ is a great swap for this car in particular because of the cost and the weight of the ol iron block bitch but ... I don't think the FA20 has a bright future either.

In my opinion - the aftermarket is over-inflating the worth of the FA20 engine due to the surge in the market that this platform (FT86) has produced.

Anyone more knowledgeable with an LS2 swap happen to know if the cog is also disturbed more than the 2j?

Not too heavy, if the total weight of the car is 2806, with a 2j thats pushing 1000 whp /800tq

I'm not so much for the fa20 either. But a 2j would totally destroy any sort of handling advantage this car offers. As much of a Toyota fan boy I am, I would rather go LSx before 2j with the 86.

But a more reasonable swap that I would enjoy would be a F20/22c swap. Heck I've even been thinking about dropping a Hyundai Genesis 2.0t motor into the car if the FA20 doesn't hold. That motor is pretty stout and would be a good alternative I believe.

$0.02

Some very good points above.

I'm personally wanting to build a track only drift 86 with a genuine 400HP ATW. Why go 2JZ?
Because I want something pretty much un breakable. I want something I can drive really hard and not have to worry about.

Yes, you can boost an FA and get it making 300/400HP pretty easy but the difference is, squeezing say 400HP out of an FA would mean it would have to be rebuilt and even so, you're realistically going to be running it at probably (rough guess) 80 odd % of it's maximum capacity. Whereas getting 400/450HP out of a 2JZ is absolute child's play. It would make that on stock internals and probably be able to sit on limiter for the rest of eternity and not ever skip a beat. Even boosting it to say 500HP with a decent size single turbo it's probably only running at 50% if that. That's why it's a good option because STRONG.

I don't really need to worry able weight and handling as it's drift only and we all know it's been done and it works great.

I guess for me I just want to see what is involved in the swap in detail. I have been quoted 50k for the whole project. Yes, I know that seems like way too much but this is from one of the best workshops in my state and they’ve come up with that price based on the fact they simply don’t know exactly whats involved. They’ve been very transparent in this whole situation and said that it could very well come in cheaper but they’d rather give me a 'worse case scenario' quote rather than saying, yep 25k and then have to start asking me for more money. Also they're work is top notch and i've always believed that you get what you pay for. I simply wouldn't trust anyone else with this project.

Plus don’t forget that I live in Australia so we pay WAY MORE more for this shit than you lucky ass yanks ;)

^^^ This is spot on and pretty much exactly matches my quote.

@JordanWho

Lol my shop said something similar. " we dont know what we are going into "

I really did my homework with this subject.


You will be making 500 VERY easily, if you are willing to take the plunge do it, its most likley rewarding, and maybe i can help you a bit too


Sent from my IBrick

Yep.

This is why I got so excited about the link in the OP because it was so detailed and was trying to answer all the questions EVERYONE has.

I hope someone does else does the swap and can document it.

Ps.

NOT INTERESTED IN LS.

2jz or gtfo ;) ?

Bahahaha pretty much.


But I might have to settle for FA just with less power though :brokenheart:

Turbo + low boost setting for around town. A separate map for race gas ( if ethanol is not available)

If it's for track only, at 400hp, I would use the fa20 definitely. Track is all about braking and corner speed, power is a bonus. FYI 400hp from a built fa20 would be uber realiable.

Take it from someone with a 400hp track car.

I'd track your current car
Then turbo and go 300whp
If you've mastered that, then build and go 400.

A track gt86 with 300whp from a fa20 will pants one with a 2jz and 400whp, every time.

There is a video on Youtube of an FRS with a 2jz swap and it sounds godly. I think the owner has a shop or something and it cost about 5-15k.

I'm wanting to set it up for drift. When I said track only I mean, non street legal. I have a rolling shell coming over from Japan so not ever able to be street legal.


Link?

Will only be used on the track as a dedicated drift car. Wont ever be street legal bro.

I briefly owned an ls1 NA miata. Everyone said it would ruin the balance, but to be honest I couldn't be bothered to give a damn. It was too much fun to care.

Check ekanooracing on instagram he owns the 1k+ whp gt86

This ! , do you have a build thread or a link to it ?

No I've never made a build thread, not even for my fr-s. I should do that lol.

With that price tag I'd rather buy a Supra for the track and use the FRS as a DD..

Im just waiting for a swap kit...after you buy a turbo kit, clutch and tuning to get 400hp your close to what $7-8k? You can buy a clean 2j motor and 6speed for the same price if not less....and you still can sell your FA motor and get some extra cash for the swap.

He has over 40k in it atm


Sent from my IBrick

I read it wrong

The swap cost him 25-30k and he owns a shop, but now the car kept growing and growing


Sent from my IBrick

So... $30k in parts alone? If a shop owner claims an amount it probably doesn't factor in labour at all and if it does, not everything would be accounted for.

This! For a street/track car, even 300whp is A LOT in this platform. I've outrun 1M's on a track at stock power purely because of braking points and cornering speed.

So the 2JZ engine is reliable, but how reliable will the rest of the car be when it has been cut up and pieced back together to make it all work? I'd want to be DAMN sure whoever was cutting into it and wiring it up did a perfect job so I wouldn't be spending the next 5 years chasing down gremlins left over from the swap.

For a pure race car or drift car when most of the car is tube framed anyway, and the wiring is easily accessible, sure... but for a street car, you're in for a world of pain until the kinks are all ironed out and there are plug and play solutions.
