G16 Engine Swap; What's involved?

I have an opportunity to pick-up a cheap '94 Suzuki Sidekick for the intended purpose of using the G16 engine in my Metro. Just wanted to know what's involved in the swap? From what I read elsewhere, both my G10 and the G16 have the same bolt pattern where it mates with the transmission. That true? Can I just bolt in the engine with the stock mounts? I assume there would also be some swapping of electronics and obviously running a new exhaust header. Any advice is appreciated.

You be better off starting off with a 4 cylinder Metro as it would be almost plug and play that way.
Starting off with a 3cylinder would require a complete 4/5 (4 cylinder 5 speed) or 4/3 (4 cylinder auto) donor Metro to make it work out for you.

So the transmission from a G13BB (from the later models of Swift/Metro) would be a match to the G16 block?

I've not researched it, but the G series engines should all accept the same transmissions. Your problem is going to come from needing the 4 cylinder ecu, wiring harness, fuel pump, all electronics, motor mount, transmission mounts (they are different than what's on the 3 clinder) shifter linkage, and probably several other small things that I'm not thinking of at the moment. That's why I say you need a Metro that already has the 4 cylinder it in, that way it's closer to just a motor swap.

I have a G13 with a 5 speed in it that I would sell you cheap. Its a parts car, but the 4 cylinder engine runs. The tranny is good, just does that thing where you have to wait till a full stop to shift into first (I know there is a specific name for this problem but I can't remember at the moment.

Couldn't I use the ECU and electronics from the Sidekick (as they're already designed to work with that engine)? All the engine mounts I can presumably get at the local junkyard pretty easily. My only concern then would be where the engine and transmission sit in relation to where the original one was. I mean, are the drive axles different lengths? I would think the entire package might be shifted over to one side to compensate for the extra cylinder. If that's the case then I can see why the 1.3L would be a better match.

That's what I'm saying, the G13 sits more to the driver's side to compensate for the extra cylinder. Do a little research on G16 swaps over at teamswift that way you know what all's involved.

Good bye


The g16 has a different bolt pattern on the bellhousing than the 1.3 or the 1.0. You will need an Esteem belhousing with a Metro center case to make this work. VR4 on Teamswift.net has made this conversion on a 98 Swift and it is a lot of work. I am looking for an Esteem donor at the right price to convert my car to a 1.6 16 valve. 100 hp is an exciting proposition. 70 is great, I can hardly wait for 30 more hp. Here is what it takes to install a 1.3:http://geometroforum.com/topic/4850034/

As me and my metro said, the G16 uses a different transmission. And yes, all the mounts, linkages, both axles will be different than what you have in your three cylinder. You need an entire four cylinder car, preferably a 98-01 so it has the G13BB, then after doing that conversion, you need to start considering the G13BB to G16BB conversion. The transmission needs to be changed so that the block will bolt up, then a lot of plumbing and exhaust needs to be changed as the block is taller.

I think it would make more sense to put the crank and pistons in a G13 block (you're going to have to find some shorter rods) and then use the head and intake from the G16. That way you'll get all the displacement, but the plumbing will all still fit. You're still better off starting with an Esteem engine though, as it is installed East-West like our cars are.

I'm not a big fan of that G16. If I were going to do a swap, I'd buy a complete Esteem with the J18 and swap that in.

wouldn't that engine block be even bigger to fit ? and why buy the complete esteem engine

Because the j18 is a completely different engine.

I bought the entire engine because there was no write up on how to do the swap. I'm glad I did as you need quite a few g16 esteem parts to make it work.


I've thought about doing a j18 but maybe in the future. Don't have space right now to have a dead esteem

The J18 is slightly bigger, and it would be more of a custom install, but if you're going to all that work, you may as well get a capable motor.

well maybe next time ! i just have the engine block. i have a second 16valve SOHC head which will go onto the G16.
