suzuki M15A/M16A

buddyboy · Postby **buddyboy** » August 18th, 2010, 6:56 am

does anyone out there know anything about the suzuki m-series engines. i have a m15a engine out of a suzuki ignis in a off road buggy. the class we run in has a limit of 1650cc with the suzuki having 1500cc. we are wanting to upgrade to more horsepower n was hoping to put a m16a engine in. what are the physical differences of the two engines? Will the m16a engine bolt straight up to the existing adaptor plate, extractors, intake etc? any info would be great!!

^^ m16a bigger Cams ,bigger valves ,bigger ports, higher compression (11.1= 1 ) oil squirts , cast longer aluminum intake phlenum instead of the plastic , bigger trottle body bigger injectors more wilder ecu & oil cooler ( this is from the swift sport ) the sx4 m16a is just a bigger version to the m15a except that it has cast aluminum intake phlenum instead of the plastic and a slightly bigger trottle body. now your best bet is to get a complete m16a from a swift sport and use the m15a ecu and harness ,trust me( viewtopic.php?f=37&t=313676 ) find a cable trottle body and modify it to fit on the intake get a emanage ultimate and tune the sheit out of it or if you have the cash a standalone .. and you good to go

So basically...is a easy swap den? :roll:

just joking.

buddyboy which m15a do you have? Was it an ignis sport you got it from or a regular ignis. I believe the only m15a that came in ignis' were the sport, the regular ignis used the m13a.

not to stray off topic ... but i highlighted the areas where u very wrong compared to the ignis sport engine

^^^it is a waste of money to sway the ignis sport m15a for the swift sport m16a

talk done

^^Yep thats true, but amir what i tryin to find out is if it is really a ignis sport engine this man have or if is a regular m15a.....and if it is a sport where he get dat ????? lol

And everything marcus said above would be correct if it were an m15a like what he had in his swift...not an ignis sport m15a

Why dont they add another suffix to denote sport engines?
like m16a and m16as,
surely that would make more sense?
Unless there already is a suffix and i dont know about it,
in which case disregard my post

^^that would make a lot of sense JM3, and no there isn't any suffix to my knowing.

thanks for the feedback. i feel it probably is not a waste of time n money putting a M16A engine in as it will only be the cost of the engine if everything was to bolt straight in with the exhaust n intake manifolds bolting straight in. To put a new engine in eg Toyota 20valve etc, there would be the cost of wiring it in, manufacturing extractors, intake pipes, raidator pipes, adaptor plate etc. So is n e one able to give a yes or no answer if the existing exhaust, intake adaptor plate from the m15a will fit on the m16a engine?

u will need to wire over the engine .......
u will need to go standalone ecu
u are going to gain a neck breaking 10-12 whp

sss m16a are not cheap why not turbo charge or supercharge your m15a? i already spoke to blue coral racing about building a manifold for my swift sport so im sure they'd do it for an m15a about 10k maybe even less depending on what kinda parts you want to use would build you a turbo m15a powered buggy lol (think that would be kinda scary though lol).

what version would you use manual or auto? that may be a silly question tbh.

^^^

the class we run in has a limit of 1650cc with the suzuki having 1500cc

If he turbo or supercharge he will out of his limit. If he has a m15a from an igis sport just use the 1600 sport block and u good

u will need to wire over the engine .......
u will need to go standalone ecu

^^No trust me he will not need to all he needs is the engine harness from the swift sport intact and a couple of rewire work for the TPS sensor on the cable trottle he will be using and a piggy back with the m15a ecu. If me got the m15a engine harness he may need to modify it .

Correct. The M15A Ignis Sport engine has more doo-dads than the "regular" M15A in the standard Swift.

Also, the Swift Sport M16A is different (internals, oil squirters, intake manifold, ports) from teh M16A found in other suzukis, such as the SX4.

how does forced induction increase 1500 to 1650+? is it an n/a only class?

^^ There is a formula that you can work out i think its cc + boost / constant = uprated cc. Nissan used it in their superturbo march to enter it in the 1600 class Jr rally thats why the super turbo engine is a 930 cc instead of the turbo engine being 998 or 1000 cc

the engine we have is a m15a out of a ignis. our class only enalbes us to run naturally aspirated engines. The main bearings keep spinning due to lack of oil. We are planning on purchasing a m16a engine which have bigger oil galleries. (apparently). if not we will get them machined. the head we have on the m15a has had alot of work done to it so it will be fitted to the m16a engine. we run a microtech ECU. can anyone give me any tips on which model we should be getting the m16a from. We are hoping the engine block pattern is the same as the m15a so it will bolt straight to the adaptor plate.
