So other than Toyota engines, am I missing any options that bolt up to/work with the W56?

1.3l Suzuki
1.6l Suzuki
2.0l Suzuki
4.3V6 GM
4.3V8 GM
VW TDI

This is really all I’m seeing. But I see this may have some Jeep bellhousings that I’m unaware of. Can’t confirm but maybe the AW4 bellhousing?

Anyone an aficionado with these transmissions and the engines they’ve mated to?
 
2.5l 4 cylinder from a jeep will bolt up but you need the ax5 bell housing on the w56.

Aw4 are swapped behind the toyota stuff by using the a340 bellhousing/flywheel/tc with the aw4. R150 and ax15 do the whole bell housing swap too.

I currently have a 2.0l with harness and ECU that’s probably going in the buggy. Snagged it from Bad Zuki.

Just weighing all the options of power to weight ratio of the engines. Toyota engines are pretty heavy for the power they make.

Wuz-A-Zuk mentioned a turbo Yaris engine making ridiculous HP and torque for size. Seems to be a rare find out in the wild, though.

I searched so many combinations to see what would fit a W56 transmission. This never came up. Thanks, man. This might be a game changer.

Looking at the Honda K series and I was like, I do not want to change my whole driveline, relocate my battery, re-do my floors, my center console, etc.

This is awesome. :smokin:
 
It didn't come up until I searched W58

Supra used a W58, tacoma W58, and I believe 2wd Toyota was W55

They should all be able to be bellhousing swapped. I know the 56 and 59 bells do as that's how people put 3rz's in place of 22re's. I believe people used the W58 bell on w56s to swap the 7mgte into Toyotas back in the day as well. Just make sure to look into it, as I know they sometimes do mix it up a bit with input lengths.

Toyota made some bad ass smaller 4cyl also, but I honestly don't know if they can be adapted to the W56. The Honda k just has so much support and came in everything. There is a reason they call it the ls of 4cyl's

i didn't know this. early pirate sounds like input may be an issue but it could be worked out. have you don't it before?

i know the g54 and ax5 are nearly the same trans.

Yeah the splines are different but you can do some mixing and match of clutch parts to make it all work.

Is the 2.4 in the later TJs the same bolt pattern? Iirc, it's the same family as the srt neon?

Edit: some Google says they are similar engines but in short would have to switch to an r150/151 and do some ****ery to get it to work. The srt4 engine is legit, but sounds like a lot of work for an obscure engine when the Honda K is everywhere.

I was going to suggest maybe asking what bellhousings would bolt to a W56, Just one more way to cross-reference compatibility.
 
What is the use case?

I don't see anything in that list being an upgrade or something where a W series will survive the power for a road rig. Buggy maybe if high rev is your game but I don't see most of those being even a lateral move so why bother?
 
K series motors can make some serious power without doing much to them, K24A from a 2015+ tsl is 215 hp with no mods

It's a tiny buggy with an 80hp zuk engine. Anything is an upgrade.

3rz is going to be what everyone says, but they're pretty heavy in the 4cyl world. The current engine is ~200lbs. 3rz's are also very hard to find since they all blow up, but for some reason everyone still wants them.

I agree the jeep engine is more or less equal to a 22re.

I feel the Honda k motors would be a good fit. ~160-200hp stock. Aluminum head and block. I would have assumed they were pretty light, but Google says 331lbs? More than I would have thought and not that far off a 3rz according to google.

Biggest benefit to a k series is they're everywhere. Cheap and plentiful if you hurt one, plus good aftermarket support.

K Series is the nest option.

Even Myron has been saying K Series are the future for Suzuki engine swaps. Just need more bellhousing adapter options like the LS has.

But from what you posted it looks like a W58 bell to W56 transmission might be possible depending on years. Biggest obstacle looks like the input length.
 
There are probably almost as many adapters as an LS. Problem is most will be for rwd car transmissions.

The link I sent says it will work for W56's as well.

i would go for 2rz, easy to find, reliable, hold up. didn't chilkat have a 2rz in his turbo buggy from the old site?
 
I see all the 3rz love on here.

My 1st hand experience with a hand full of buddies is that 2/3rz are not that reliable. They all burnt valves or blew them up.

Then when they blow up there is like 5 or 6 different versions (including 2tr) and they don't easily swap. So when you do find one, it's the wrong year.

To thier defense, from what they said, there might not be another common 4 cyl with better low end than a 3rz.

Those 4 cylinders in the Tacos and 4Runners have always been the less desirable options over the 3.4l.

I grabbed a complete Tracker 2.0l off Bad Zuki for an easier/quicker engine swap if I need more power, but a forever motor would be the K series. The aftermarket support is superior to anything Suzuki. It also makes more HP/torque stock than the 2.0l.

Wuz-A-Zuk wants to sell me a set of wheels for my one ton swap and said he’s throw me a K series engine. So…who knows what the future holds. Current finances/economy says I’ll be wheeling Toyotas forever. :laughing:

Ya, in the stock taco sure. Yota guys jizz over the 2/3rz. It is a good swap for a 22re, pretty simple and I know it's a good bump in power, especially low and mid range. But I've just heard so many issues, and finding them is hard, which is a huge deal breaker for me.

2.0 should bolt in place of the 1.6, might need a custom flywheel iirc. But that's a bonus. I've had an 8v and 2.0, it will probably feel like double the power. They're not near as common as a k series, but somewhat easy to find. Last time I was at the junkyard, there was 4.

One dowside to the K series, is they're all FWD configuration (save the s2000, but 99% chance you're not finding one)

Not sure it will matter at all in a buggy, but iirc, the intake point at the firewall and most people buy aftermarket intake manifolds for rwd swaps.

Feel free to post them up. I've looked a hand full of times over the years, never seen a good donor for a reasonable price. Not talking about a long block laying behind a shed.

Buddy blew his up and looked for years, but every time he found one, it was the wrong year since they changed something every other year on them.
 
if i ever had a buggy i'd find a way to package a Subaru EJ into it. those things are everywhere in the PNW. cheap. buy a JDM engine with 50k on it if you're feeling bougie. you can convert the trans to RWD and run a divorced samurai case.
 
I can see the different versions of those motors making things a bit more of a challenge. Cant say they seem any less reliable than the 3.4's though. Werent the 2RZ's mainly in the 2wd rigs?
