kia stinger 1jz swap

[boosted1g]

Something's not right BC the 2.5T (300HP) wasn't available until the 2022 MY, so there's that....Now, replacing the 2.0T (255 HP) available in 2021 makes sense.

Questioned that as well when I read the original post; but in the end it makes no difference for the advice given in the replies.

hello world ive recently been thinking about swapping engines in my kia stinger and i wanted to hear some feedback about my ideas.So i have a gtline kia stinger 2021 and i am thinking about swapping the 2.5 Litre for a 1jz mainly because of the power i could potentially get out of that engine but i am wondering if there are things i should be doing to my car before i start swapping engines like should i be reinforcing certain things in the engine bay and also if you guys had the chance to swap the engines what would you go for and why ? i am doing as much research as possible,do you guys think that a swap like this is even possible? i know i might lose certain features like the engine start stop but i relly didnt care for it any way ,do guys think that im living in the clouds with this one?

Have you done an engine swap before? In a recent (> 2018) car? Between different manufacturers, not just between engine offerings? With a 15+ year OLDER engine?

If you were trying to swap a '22 Mustang 2.3 to a '22 Mustang 5.0, that would be one thing - you could look up the different parts, try to swap them, see if everything works - and even then, run into issues. But you could probably get it to work.

But swapping a 15+ year old engine into a modern car? Look, if you have $50K+ burning a hole in your pocket, and a willingness to wait 2-3 years, sure.. And then, be stuck with a possibly un-registerable off-road only car. That never runs right, loses airbags, all stereo, HVAC, etc..

This isn't dropping a huge engine into an 80s Mustang.

In those states that follow CARB rules, this swap is de facto illegal, since you're moving to older emissions regulations.

Trade up for a 3.3 ($15K?), add WMI / CPI / Lap3 for another $10K and get a reasonably safe / easy 500 whp. It'll run better with less hassles than a swapped car EVER would.

Shoot, in California you get pulled over for having a stock exhaust

If you are just wanting a truly unique build why not!!>???? but you'd need access/have a fab shop as pretty much everything would probably need to be custom. If you have the funds and time to do a build absolutely do it! I think custom stuff like that is sweet.. Is it the smart thing to do if you are just wanting something faster ? no, custom never is.. but it would be epic! I don't know that the i6 would even fit without massive re construction of the engine bay... straight 6 motors are very long... it would be easier to fit a v8 in the bay than an i6 IMO... i can't find exact dimensions of the 3.3tt v6 but comparing other v6 to the i6 motors it's at least 6-10 inches longer...

DO IT!!!!!! YASSS QUEEEN

so you think its possible man im willing to dish out 16k just for the swap alone and about 7 to 8 grand to get the engine i just wanna make sure everthing is gonna fit in a kia stinger engine bay im definetly gonna be cutting a few things out but then i also have to think about the wiring and then getting the thing to start

seems like the safer route

Go LS!
5.3, 6.0, 6.2 built with a big cam and a massive turbo. Those motors are plentiful. Much cheaper build than a 2jz. Now, I have no idea if that would even fit but that's what I'd do.

Sorry if I'm not up to speed on some of the previously mentioned engine modifications. What's the 2JZ? Thanks, Don

The 2jz line is the family of 2.5 and 3 liter inline 6 engines from Toyota. Most famously the 2jz-gte is the twin turbo model found in the 93-98 supra that is known for being able to handle big power upgrades.

If you were asking to swap a 90s engine into a 90s era car then it would be reasonably straight forward and that would be a completely realistic budget. But you are trying to put it into a modern car with can-bus between the various computers, drive-by-wire, digital gauge cluster, etc, etc. Every engine related electronic component would either have to be reverse-engineered to work, or replaced with a less complicated system. Like I said, at this point we are not even sure if climate or radio would work since we don't know how the body control module will act with no can-bus communication to the ecu.

Any shop with the talent to make this work well would be at least 40k+ in labor, and as someone else said, depending on your state you may still only be able to register it as "off-road only" vehicle. This is a SEMA show type of project for someone with deep pockets.
If you want a fun engine-swap car then go pickup an 80s or 90s car (which will be much lighter than a stinger) and have at it. If you want a fast stinger, then trade in your stinger for a 3.3L one and mod it.

the fitting part will just need to be measuring, the money part is the big variable... if you don't need any of the incar electronics /ac etc probably could do for about that much... but trying to get everything else to work/retrofit similar features is the big unknown

You’re gonna spend a heck of a lot more than that. For comparison, here is my brother’s car he swapped:

He estimated he has $20-25k into just the swap alone, which includes brakes and other odds/ends. Mind you, this is for a 30+ year old car. He also did all the work himself minus building the engine which was only a couple grand.

I like your attitude towards the swap, but I don’t think you quite understand the magnitude of what you’re trying to do still.

A good motto to live by; cheap, fast, and reliable, pick two and live with the consequences.

Do some of these mods apply to the newer, BMW sourced engines in the newer Supras? Don

This post wasn't about mods per se, rather a whole engine swap to the 1jz or 2jz motor. The new supras have the b58 inline 6 from bmw (which is an amazing engine btw) which has been referred to as the modern day 2jz since it has such high tunability potential as well.

Thanks, that clears up a lot of things. Don

Thats how i went about my jz rx7 thing
Personally i was 7 or 8 thousand into the engine with a small (bigger than stock) single turbo aftermarket intake fuel rail coils and mate plate for the transmission. Then the wireing needed done. And an ecu was required. And this was 2013 prices and parts.

A few hundred man hours and 10 to 15 k coupd see it done. If done solo (without a shop)

Then add at least a few thousand after that for a tune. But if you know tuning thats more money saved.

Gonna need welding skills to make mounta for the tranny and engine..

A driveline shop for that.

It would be mad tho
