I'm quite interesting to Build a Mk2 swift Race Car, as mk2 is still production in China, it is a low price good handling chassis--it got independent rear suspension which the new Swift didn't, & 1.6T is a common class here.

build a G16 Turbo will be interesting, but the DOHC head & 16 crankshaft is difficult to find here, but I can get M16 from SX4, Should I just take a M16 on the Mk2?

Not much knowledge base on this forum about the m16, there have been plenty of discussion on these two engines on Redlinegti.

I haven't got first hand knowledge on this matter but will surmise what I've researched.

Both engines are fine for mid range boost, 200-220hp should be reliable anymore than that you would be better off using the g13b.

The M16 has a very thin block, the point halfway down where the sleeves sits is apparently around 50mm thick, what happens under big boost is the block flexes outwards allowing the sleeves to sink slightly which blows the head gasket, not even Darton sleeves tied into a plate cures this.
The only person who seems to have cured this is Monster and it wouldn't surprise me if they just used the original cad cam files and machined up a thicker block to suit, no one else seems to have solved this issue yet and is the reason why this engine will never be popular for big boost.

The G16 requires a lot of work to swap in a honda crank and make a girdle.

The B16 and 4agze are much better 1.6 engines for big boost.

The G16 bore to stroke ratio is all wrong to rev highly, with such a long stroke the piston speed is very high, you won't be able to rev to 9k or above like the 4age or b16 for long periods.

I would think an NA G16 should be in a different class than a g16 turbo?

G13b should take care of any of your concerns.

yes, but 1.6 & 1.6T are also popular in China

Looks like Swap to B16A directly is a better choice?

If you want to run a 1600 then yes I'm afraid to say the b16 and 4age are much better engines, no reason why a well developed G13b can't be competitive with those engines though.
