what the most power somebody has made n/a with a SOHC 16v? i would like 140 whp but don't know how realistic that is i can't seem to find anything for this engine like cams or pistons

You could squeeze 120 out of one, but
you would loose low end grunt in search
of your HP figures.

I could steer you in the right direction on parts,
but I need to know if you have a limit on your
buildup.

What do you want to acheive? What is your budget? How far are you prepared to go? There are options available but it will require some work on your part to source them and get it put together in a way that will work for you. Do you want to keep it stock internally or are you willing to resleeve it for 78 or 79mm pistons? Cams can be sourced but it depends on what type of cam spec you want as to whether you may need to look at your rockers. Headers are available but again depending on what you are trying achieve you may need to look at custom building some to suit. 1.3 flywheels will help a manual and underdrive and adjustable cam pulleys are available. Some port matching and undercutting the valves is an option. Also there is a crank scraper to suit and a windage tray can be organised. Honda D16 pistons could be used for more compression etc, etc. I know of someone who builds these motors for speedway racing here for high rpm power. There is always aftermarket computers.

In mine I just did a cam and adjustable cam gear and some Tri-Y headers with a 2" exhaust and freeflowing cat and turbo muffler. It certainly woke it up without losing any reliability as I used it as a daily driver as well as offroad.

Hey Wild you are right again...

     You can build 140hp from a 1,6/16v, but you are not gonna want to 4X4 with it. The cam timing needed, injection mods, exhaust and head mods are going to produce a rice rocket style motor.....lots up top but little down low.

     If you just gotta have that kind of normally aspirated power yoou should be looking at a 2.0 swap. 130hp out of the box, lots of torque easy parts availability.

How many HP is the adj cam gear worth? What about $? And where can I get it?

Thx,

adjust. cam gear doesn't realy make hp on sohc..it just allow you to move your power and torque curve around   at  high end or low end   depend on where you want your power to be ..    on dohc   you can dial them to  the right valves over lap   ..that would
make lil hp .. good luck

Or you could always swap in the 2.5 V-6 and have 165 HP and 162 ft-lbs torque or even the 2.7 V-6 and have 185 HP and 184 ft-lbs torque!!!  :o

As mentioned, the adjustable cam gear doesn't make hp as such but lets you shift the power/torque curves either way. What that means is the amount of power/torque available to you at a certain rpm can be increased more in line with where you want it. For example by bringing the powr 500rpm earlier on a 16v you could now have say 20% more power at 3000rpm than you did previously.

I wish I could swap in a 2.0 legally here in CA 


Ive heard that it is possible to put a DOHC Head on the 16v...not sure if anyone here has attempted it or if its worth it

1.3 Swift GT DOHC head will fit,
but they are hard to find.

you can as long as it is the same year or newer motor for the vehicle and meets all smog laws. you cant go back in technology, but you can go forward. so if its for your 93, you should be fine.

I would like to do a diesel swap, like a peugeot 1.9 out of a 505. There are a few of them out there, and nobody cares about them. Or,a Isuzu I-mark diesel swap, as nobody cares about these either. their only downfall is that they are more rare than the 505. I saw one in the pick and pull and wanted the whole car, but the d bags at pick and pull said that if a car is in the back area of the lot, then it goes to the crusher . It is really too bad, as I have seen some vehicles out there with low miles and excellent condition.

Wouldn't it be fairly difficult to get all the OBD II sensors running in a new car such as mine on this swap?

Diesel is exempt from OBDII until around 2001
or so.

I dont understand.

If you can move the torque curve with the cam gear... and you move it upwards in RPM to say 4800 RPM 100 ft/lbs pk TQ instead of 4200 RPM 100 ft/lbs pk TQ, since HP = (TQ*RPM)/5252, then how can you not be making more HP?
