Question 1.6 16 valve performance

Ok, I have a 95 ( pre obd2 ) 1.6 16 valve swapped into my Dads and also my own samurai. Both are bone stock engines with stock exhaust (2" from cat back) and air box. What I would like to know is, for the money and ease of installation, what is the hands down best performance mod for a 16 valve? These engines in stock form are impressive enough in a samurai but what are the options? I have read about the performance "chips" available for these things and am skeptical but without basis, I have no experience or reliable feedback on them. Im finding it hard to believe the doug thourley header is much better than the stock manifold but again, just guessing. Is it worth the time and money for a turbo? Im looking for answers from people who know from experience. Yes! I searched, it sucked. thanks!

I'm actually really interested as well. I was going to post a thread about it. I just got my 16v to run right, and I am seriously stunned by its performance, it hauls ass! But once you catch the go fast bug you can't get rid of it, so I too want to do something fast and easy (somewhat) to make this thing faster.

Sub'd!

I heard a torque cam regrind from Delta Cam really wakes these up. I would like to try one in my wifes hard top sammy that is getting a 3spd auto behind the 1.6.

I wish I could tell you what's been done to mine. Bought it used off a member here, he said it had a cam that helps keep it from stalling at low speeds and a header. Not sure how these compare over stock but I know it hauls compared to the 1.3

A turbo. Or a bigger engine.

My 16v is stock, those are the only two things I would really consider if I wanted more power

Yep even for the big block sami motor they are pretty anemic. I know a guy with a custom manifold jackson super charger from a honda on his and it does...better

I havent seen him in a while, could be cause I sold my sami... But im building a new one but its not a sami But he used to be around hollister a lot next time I see him I'll snap a few pics. I want to say it was a 16 valve with an 8 valve manifold and he built the adapter to the blower.

Who here has gone the turbo route? whats to be expected as far as mods and hp gains? Do you experience turbo lag? if so, how bad? Is a cam worth the time and money? Thanks!

From my brief foray into this engine (89 swift GT), the 'word' was that the chips were a worthwhile endeavor for these engines. Specifics? Can't speak from experience, but some of the members on teamswift.net could offer some better insight.

Here is a good turbo 16v thread


Turbo 1.6 16V Tracker/Sidekick motor in a Samurai = FAST FUN!


and like schadenfreude said, teamswift is a good source for engine performance info

I am the original owner. The cam and the header were both purchased from Hawk's suzuki. They are now out of business as I understand. The cam, as I understand, is Delta's torque grind. Hawk just rebadged it. I did the cam and the header at the same time the difference in the woods was very noticeable. The biggest difference was when wheeling it definitely idled better and would crawl over things without throttle input much better. I used to have to always cover the pedal with my foot and if I felt a tire bump something I had to blip it to keep it from stalling the cam fixed that.

Glad to here you got the spark problem figured out and got her running. That was a damn good engine in my rig and never let me down.

I kinda miss it.

Best "Bang for the Buck" in cheapest to most expensive order is:


1. Advance timing several degrees which depends on vehicle and octane of fuel used and do not let it ping (increases throttle response, but reduces gas mileage)

2. TUNE IT UP! use OEM NGK plugs (other plugs never seem to work as well), good quality wires, cap, rotor, etc


3. Use a mandrel bent 2" or 2.25" Dynomax Super-Turbo exhaust system with "high flow" CAT (gutted works the best) and the stock manifold actually flows very well (meaning a header is not a necessity to gain power).

4. CAM ......changes the location of the power band and is better for some applications. I prefer using an adjustable CAM gear which does similar, but is less expensive and allows for better tuning.

5. Stand-alone fuel management system to replace the stock computer. Expensive, but required to optimize the engine performance and requires hours of tuning.

6. TURBO .... more complicated and expensive (comparatively), but produces plenty of useable power and you can safely get 5-6 PSI out of a system good for about 40-60hp befre reaching the limits of the stock EFI system

7. Supercharger .... also complicated and expensive and similar to the turbo, but costs and performance are similar.


Probably missed something and did not get in to doing internal motor work (shaving head, boring or stroking motor, etc) or motor swaps like the 2.0 or 2.3 liter which are NIGHT AND DAY difference over the 1.6, but these are the things I have experience with. I have never used the "chips" on the market and do not know anyone that has.

I had a 16 "built" in my last sammy. Bored .030 over, shaved head, the works. I tried using a performance cam but it kept breking the adjusting studs. Hawk said they sent me a bad grind but I just put the stocker back in.

Anyhow, the jump in performance was very noticable from stock. It was very snappy, and reved quickly and smoothly. It had more power than stock but was not a fast car by any means. And after driving my 4 door with the turbo Audi motor, the sammy was slow as hell.

But it's still not a ZUK motor You know some of us are Suzuki Purists when it comes to our vehicles. Swap in a 2.0 Vitara/Tracker motor or a 2.3 liter Aerio motor and you would be surprised

Yeah, I used to be like that also. And if something happens to this motor I will probably put a 2.7 V-6 in it.
