Hello all im lookin to build up a engine in the garage and have a few questions for some more qualified than I peoples so any feed back will be accepted....
i know i want to build a MPFI g16 either turbo or blower ready, beside the obvious of getting forged and strengthened block components what kind of head should i go with? im interested in changin to DOHC setup but on the other hand i heard that the SOHC would be more compatiable withboost...if not which head should i go after and what mods if any to make it work with the block?
ECU to run the motor... with the setup. What sort of vehicle is this going in, a tracker? You are in for a load of issues and trouble to work with. I hope its not meant to be a daily driver in the next couple of months. Your main issue is the ECU, then its anything you want to do from their.

yea the car is eithor gonna be a tracker or a sidekick...i had one in the past and loved it to pieces. im gonna be buildinr the motor in my garage, so transport is not an issue. Im fairly learned on cars and just need some guidence from some guru's.
i was hoping to use the stock ecu and get a piggyback system of sorts. The plan is a streetable weekend warrior that runs round 11-14 lbs boost lookin to get round 175 RWHP

With that number, its not achievable with just the motor without major issues. Piggybacking is not possible with the Suzuki ECU unless you want to waste your life (honest opinion).
Swap it out for a Chevy 4.3 V6 if you want this amount of power... easiest or VW engine of choice.

Hi some of the probs you will be running into is this motor will be the fact that the motor is already maxed out for the 80+ hp it already has.
So in order to get more hp you have to look at the weak points of the motor.
After resolving the ecu problem then you need to go on to the next step. The crank and rods are next. The crank is hollow and the rods are rather weak for your purpose , so they will have to be replaced with some thing stonger and custom made. the pistons should be ok but I think concave would be better for a turbo. Since your thinking of running 175hp will your injectors do the job? Possibly not.
The point I'm tryng to make is YES it can be done ,But at what cost.
Maybe an engine swap is cheaper and more economical.
I know of a person about three blocks from my place that builds suki/trackers for movie sets and they all will do 13-14 sec 1/4 mile. What he does to them is his closly gaurded secret and won't tell me what he does . The only thing I have managed to find out is that all his builds use carbs and to my knowlege no ecu. Even though this guy is a real jerk, it is his livlyhood and his job so I guess I shouldn't really blame him for not giving out any info. I have seen a few of his trackers/sukis out on a road test and I can say that they are ......fast... .
Oh yea I forgot to mention that he only uses the 1,6L 16v engines.
click amazon.com
search Jeff Harman, 2 books, both are beyond belief.
read the books, then your questions will get real good. and most answered.
like this:
how can i stop my Stock ecu (with useless piggy) from blowing my motor.?
cutting to the chase.
yes, they are jerks, they like to play games, and sucker folks. many. not all but
it is hard to find good ppl with good intentions.
how much boost ?( you never said the #1 question, 1 Atmosphere?)
after spending a fortune on the motor.
consider putting in place (like toyota does) a plan that protects that motor for any failure. "what happens IF" is a top design plan.
Jeffs book has a whole chapter on that. and is the best write up ive ever read .
what will happen , is you will be driving under boost and something , anything ,may case the motor to go lean, this will blow it up. (no knock sensor will save you)
Even the STOCK eCu can cause that. huh?
remember this one fact , you , me and no own knows the code running in the stock ECU.
so how in the world can you predict what any PIGGYBACK (liar box) will do. to your ECU.?
but wait ,there is an answer, it's custom ECU.
you can have monitors running on the custom ECU, that monitor fuel pressure full time.
and take radical fast action , under boost.
That is what Toyota and most of the pro's are doing.
they learn quick at $4000 per blown motor.
Turbos are common today,
why ? because of what i just typed. the electronics can produce reliabilty and safety to the design.
In the 80s many a MFG when broke trying to honor these blown motors.
until now.
read the books, wish i had books like that in the 60s , yah !

then? how are you going to deliver this 175 rwhp ( more at the fly wheel and in to the tranny ,so tranny must handle 200HP. see? work the numbers backwards.
if you need losses on the drive train, that is easy to find.
think about the whole system.
i used wire up drag cars.
long ago. Custom everything and my custom electronic ignitions. 1966'
one day this friend of mine decided to test drive his drag Mustang.
it had 8 webers on it. 289cu-in. "all custom work to do that"
he cranked it up on the back lot, and dumped the clutch.
the left RW lug studs all sheered at once this huge drag slick flew in the air ,missing me by 12 inches and distroyed the garage door and many things inside next to me.
400 HP did that.
so think about all the pieces , working together and expect the worst.
maybe a Wranger with a nice v8 ?

I would think an easier way to get more horsepower would be to use a v6 say from a gm car (3500 or 3800 v6) It would be far easier to make it adapt to the zuki driveline (and cheaper) than to try to get more out of the 4cy. Then you have the problem of the zuki driveline holding up to more horsepower. just my thought

Only two defining forces have ever offered to die for you;
Jesus Christ and the American G.I.
One died for your soul, the other for your freedom
they have modular C.A.N buss ECUs. comming.
one can just plug in a ignition module for your car type and start right up.
after loading the defaults for your motor size.
they have software that allows you to input your motors config.
and then it creates conservative starting tables.
and
they have software that allows you to drive and log data.
this data (i call it the road dyno) this data is then reprocessed thru more software
and it makes cleaner more accurate tables.
not as good as dyno time but its almost free. many are happy with doing this all their selves. but turbo mode will require dyno tuning. no bypassing that step.
read jeffs book, it will save you from your self. see the pit falls before you fall..
cheers.
