Default Making my stock Sami road worthy

Hello, I'm new to this forum and to the Suzuki Samurai. I bought a 1988 Sami that was 100 percent stock, as it would have been from the dealer, with 100,000 miles on it. The original owner kept it garaged and only towed it from place to place. So, my first project is to make this car have enough pep to keep up on the interstate so I can take it on some decent distance trips. My first question is; is it possible to give a Samurai some extra power without completely swapping a motor? If it isn't, what is the suggested motor to swap with? Would adding a bigger Carb. on it do much on it's own? Also if anyone could suggest a decent suspension and lift kit for a Samurai that would be great too. I plan on taking this car 3 hours out to D.C. this weekend do you think it will make it ok with stock parts? It's in amazing shape for its age, the worst thing wrong with it is that the Heater doesn't work. Which, I have already found is a bad heater core. Thanks for your time.

-Antonio

samurai does just fine stock. When you start sticking big oversized tires on it then you really feel the lack of power. Gearing it down helps a lot. Reduced transfer case gears are very common, so is a differential re-gearing.

Camden makes a supercharger for the samurai, but it's not cheap. (it is compared to other superchargers, but for tight penny pinching samurai owners it's expensive) I've seen a few budget junk yard turbo samurai builds. You can put an aftermarket carb on it and it gives it a little more pep. Putting a side draft CV carb on it gives the little engine a lot of pep. You won't be smog legal in most emission controlled states though if you do any of these intake alterations.

You might try one of these it is cheap and won't take to long to install but if you keep it stock it will do fine.

Thanks for help, I'm glad to know my trip to D.C. will be good. I'll be glad to take the top off in the, soon to be, good weather. So, one more question for anyone. My ultimate goal will be to re-gear both the transfer case and the differentials. Also, I would like to add a few inches of lift and bigger tires, not sure how big just yet, and I'm going to add power steering including a larger battery, alternator, and larger gauge wires for the wiring harness. My question is, after having read all of this, does anyone know of a good way to add power steering? Is there a kit, or do I need to junk yard the parts out of a newer geo or jimmy?

You will double the HP with bolt on GSXR kits. Get better gas mileage too.

Not that hard to tune if you have the tools and good carbs. I did 19' burnouts with new 31x10.50 Trxus MTS. No tellin how long a stock tire will smoke. You will bury the speedo if you have the nuts to drive it that fast.

NOT TRUE.........

May add 20-30% But I'd have to se the dyno # to believe that.

To set up an engine to run those carbs correctly will require re-cam-ming the engine and extensive exhaust mods.

Not to mention the head porting and valve train work.

If it was that easy we would ALL HAVE GONE THAT ROUTE LONG AGO.

Look, you bought a Samurai. If you wanted a Porsche you should have bought one.

The 1300cc hp can be increased in small increments very easily.

A cam , exhaust and carb upgrade, ( Webber, Toyota, CV, or Holley 5150, All work nicely.

Some work better than others off road.

NONE will double you're HP.

That costs real $$$$$$ Talent and time.

Any one telling you any different is blowing smoke up you're nether region....

The 1300cc Suzuki motor suffers from the same problems ALL Suzuki motors are prone to. Week crank case journals.

If you push it past 100hp plan on stress cracks in the block.

Just realize that no matter what you do to you're rig. IT is, and will always be a utility vehicle. Not an economy car and defiantly not a race car.....

This is how you double the HP in a Samurai.

I don't know where to begin. You are clearly uniformed and should be before making blanket statements as you have. Do the research for I am not going to go over the thousands of posts to prove a known point.
Start here. Search for:
4wd and sports utility magazine article on the Samurai Guy Wild Bore GSXR kit.

My personal Sammy site. Click on the various links throughout.
Sammy
Ask anyone that has seem my Sammy and how it can keep up with or blow away built 16v's with cams and headers. All on a stock Sammy motor down to the 1.375" tail pipe except with the carbs.
29' burnouts picts with brand new 31x10.50 Truxus MTS. The car.

The rubber laid. There was no braking during these.


Fastspec2 dyno results. Thread starts. Some dyno numbers.
Link to results image.


There are multiple threads on the forums of my builds.
GSXR Lives! - Zukikrawlers

Samurai Guy "Wild Bore" set up???
The evolution from the SG intake kits I had with over 168000 reads and 78 pgs of tech.
[URL="http://bbs.zuwharrie.com/content?topic=70640.0"]http://bbs.zuwharrie.com/content?topic=70640.0[/URL

As for why everyone doesn't have some kind of GSX kit on I can only speculate. The main issue is the $1300 cost, the fear of spending another few hundred on tuning tools and the know how on how to tune multiple carbs. I would of thought that if anyone told me they could double the HP on a $1300 investment I would of told them they are crazy but sign me up.
Just like the cable locker I made and it was tooted as the best product that was ever made for the Sammy but try to get a cheap ass Sammy owner to fork out even $400 for a Proto one is beyond me. Let alone the $900 it cost me to make one.

I have put well over 140000 miles on my intake kit, and driven the locker for 20000 miles without issues. Even yanked out 7000 lb stuck expedition Land Cruiser FJ80 with 30 snatches without him being under power 2 weeks ago.

I see alot of the links from Fastpec2 have been removed. Some are there if you right click on the image and open in a new tab, Then click on continue to media link.
He built a spec motor and dyno'd many different setups with the same motor. New close to stock engine put out 40 hp to the wheels and 78 with no elaborate tuning put out 78 hp. I have the pictures on my other hard drive of the multiple run test results.
There is also a good bit of info from other guys who built their own setups on Pirate too.
