One other consideration I have for buying a samurai is I may be going to visit family in the rocky mountains sometimes. Has anyone driven a samurai through the mountains? How was the power? How hard is the stock carb to rejet if I needed/wanted to when I got there? What about the weber carbs? Also I would be towing it not driving it the whole way. (I'm 14 or so hours away.)

No replies yet? Come on, all you guys that live out there in/near the Rockies, what do you do? Are you carbs stock?

My 87 Sami has tbi carb.
I was running it most of the time between 7000 and 11000 feet (Sangre de Cristo) south end of Rockies. It had only a very slight attitude (altitude) problem when it was cold (snowing) Otherwise it ran good. It adjusted itself.
Next big usage was at sea level and it runs good there too.
If it runs for u at home it should run good in the mtns...in my experience.
My experience with the ECU equipped is the same...my buddy has one.
If u drag it that far I always take the driveshaft(D/S) off the rear diff. If it has free wheeling hubs on the front turned out, u will not need to drop the front D/S. Read this forum to find out what happens if ur rig falls into gear while u r towing. (read:disaster)
Good luck with ur search...keep it up and u will find a good one.

If you have an EFI model then it adjusts automatically. I believe there was an alternatie main jet for the carb models, you would need to check the FSM or ask a main dealer

The stock carb, on a US market Samurai automatically compensates for altitude if everything is properly functioning. It will lose power based on altitude, but the mixture remains correct.

Aftermarket carbs will lose more power with altitude, as they keep putting the same amount of fuel into an ever decreasing amount of air. They can be rejetted for higher altitude, but that is not a good solution for a trip through the mountains if you live at low elevation.

'90+ Samurai comes with fuel injection and also automatically compensates.

Of course engine swaps are always an option as well.

That's cool. I realize that fuel injection automatically compensates, I just didn't know that any Samurais had it. So exactly which years/models will have carbs and which will have fuel injection? And also, is it like modern fuel injection with an injector for each cylinder or some form of throttle body injection?

1986 to 1989 had a carb. 1990 to 1995 had throttle body fuel injection, with a single injector. If I had it to do over again, I'd of held out for an injected Sami, as the carb(a fresh rebuild) has been giving me fits. I probably just need to pull it apart and clean it out, as the previous owner put a new carb on a year old tank of gas... WTF!?

The '86-89 carb represents the last gasp of carb technology. It has a mixture control solenoid on the primary bore that is controlled by the Engine Control Module which looks at an oxygen sensor to keep the correct mixture supplied to the engine.

Of course, the carb is pretty complex as far as carbs go with the typical snake's nest of vacuum hoses from the mid '80s. The nickname for this type of carb is a "carbjector." If I did not live in California, I'd swap a fuel injected manifold onto the engine, as the engine is a fresh rebuild and very strong as far as 1.3's go. My Sami tops out at 90 mph with a stock carb!

It is possible to swap a port fuel injected engine into any year Samurai, though the most popular swap seems to be the throttle body injected 1.6 sohc out of the Sidekick which is a pretty simple swap.

Thorley header with a 2" exhaust, Magnaflo cat and Thrush turbo muffler.

Everything else is stock with a fresh rebuild of the engine and carb.

I've never had it any other way and this is the only Samurai I've ever driven. I do know that it pulls a lot harder as the RPM passes 4k, and keeps pulling harder and harder up to 6k. It does not feel weak below 4k, just really strong above it.

I think a big part of it is that I'm running stock sized tires and have no lift.
