M16a VVT engine swap

Hi Neil, think they are reasonably easy to get here, although I did have to wait a bit to get a 2009 version of the SSS. Plenty of guys have done this conversion, hence why I feel comfortable doing the swap.  If I was in Australia, I'd have been considering putting in the M18 engine. Can't get them here, rare as hens teeth.

Can't see you will have any problems, depending on budget and what want to achieve, Haltec sell standard alones they already have bace maps, lots of performance information and parts
Be interesting to see what you achieve

The only real difference between the various M16A applications is compression ratio. Valve train, port sizes and cam profiles are the same from 1300 to 1600 sport as far as I found out (happy to be corrected. 

The various induction systems combined with compression changes (9.5-1 to 11.1-1) give the varying outputs. 

All VVT engines are 11-1 or 11.1-1 so the only real changes are induction.

If you fit the sport engine without the induction system, it may as well be a standard 1600VVT. There is no real world difference.

My engine is early Liana VVT and has 11.1-1 compression, essentially the same engine as the sport but even with a custom map, I'm only at 98.3bhp in the Jimny as opposed to 106bhp in the Liana, that's down to the smaller throttle body/inlet manifold from the 1300 being used. 

Induction and exhaust systems are both quite restrictive across all ranges (in an effort to meet emissions targets) as standard, even on the sport.

ITB's/ecu and a good exhaust system can release over 175bhp from an otherwise standard engine.

Running the 1600 on 1300 induction works reasonably well, improves a jimny no end. I'd suggest that most owners will be very happy at that. Going further gets expensive and the improvements get smaller.

Thanks sniper,good bit of info ,food for thought
With the bore size being the same between M13,15 and 16 is it possible to put high compression pistons in the M13A ?

bore size is the same across all 3 versions of the m series, they get the different cubic size from changing the crank and rod length to get more stroke, and you can get a 1.6 in aus its just rare as not many ppl who got the swifts went for the 1.6 when it was cheaper for the 1.5, so there are a butt load of 1.5 swift motors out there, im personally getting a 1.5 from the wreckers locally for under $500 next week, may as well look at dropping forged internals and running a turbo if you think a 1.5 isnt gonna cut it on its own, but heck going from 60kw to 90kw is not nothing to snease at

Thanks Sniper,

That's exactly what I needed to know, perfect. Looks like my wishlist/shopping cart now includes:

An ITB from rzcrew
An aftermarket (?) 60mm throttle body to fit the ITB
New exhaust manifold
Exhaust with sports cat

After all that it will need a tune. I better get saving.

One question though. Would you recommend any aftermarket throttle bodies for an aftermarket ITB? I wish I knew a bit more about these performance upgrades, but I'm not a mechanic.
