I have an 86 Sammi with the 1300 carburated engine. I am wondering if I can remove all the emissions stuff like EGR and the support sensors and such. I know that there is a control module that adjusts the mixture; is the stock carb able to run purely mechanicaly? I have no emmissions testing in my area and understand that I can nurse a bit more power if the EGR is removed. Do I need to remove the ECM? Or can I even get rid of any of this stuff and still run the stock carb?

While stripping down a larger V8 will net you some power, doing it to the 1.3 won't give you enough to make any difference. It will take you more time and effort than it is worth. Just my opinion though.:cool:

A valid opinion it is Billjon. The time is no big deal as I will need to figure out what is malfunctioning anyway. My engine idles at around 2000 rpm and I know I have vaccuum leaks. This rig sat in the weeds for eight years before I resurected it. It was a condo complex for field mice and pack rats. I got it running and got a spoa done and put some good rubber on and now am setting to fixing the carb issues. Any opinions and suggestions would be helpfull. I am not interested in spending a fortune on engine mods at this point, I think gears and a couple other items need to come first.

IMHO if you really want to screw with things, yank off the oem carb and the 'puter behind the glove box and put on a weber carb. Runs better than stock.
With that said... why not fix the vac leaks. I'm not sure how much extra umph you expect to gain but it's not as much as you think.
Want more power? A lot more power? Gear the thing down. Want more? Swap in a 1.6 sidekick. Want enough power pull down a house? Drop in a VW oil burner.

I'm running the weber carb on the 1.6 with a header and larger pipes & gears.
Would love to have more gear. Why? With these vehicles you don't get them to run the highways doing 90mph. You get them to go through crap you can't even walk though.

I would love to go diesle! I work for a wrecker company and believe me, the first VW that we can aquire is mine. I just figured I might get a squeek more out of the 1.3 and save a bit of money by not replacing all that stuff but it sounds like it kinda just is what it is. And that's okay, the gears are more important to me than a hot rod engine.

remember, it's just a big air pump.
put on a better air cleaner and more open exhaust and you may have what you are looking for, for now. when I had my 1.3 I ported the head to match the exhaust header. ended up taking off a lot of metal. I did this and the carb swap at the same time.

The 1.3 runs pretty cool and has a very limited cooling system on it because of this. If you pull the EGR the combustion chamber runs hotter. It's not going to warp the head because you pulled the EGR valve out, but it will run at a less efficient temperature. You won't gain anything from it if your EGR is working. If your EGR is jacked up then you will be better blocking it off than running a busted one.
The Hitachi can be run purely mechanical but it's going to run poorly. The choke, secondary butterfly, and idle up are all electronic controlled. The best option though would be to put on an aftermarket carb or fix the Hitachi.

Putting a header on it is the easiest mod you can do for the least amount of money and will give you the most power. You can spend a bunch of money and put a linked multi throttle body setup on it, but if you don't open the exhaust up with a larger pipe and headder, you won't get anything out of it.

But First spend the $5 of a foot of vacuum hose and replace them all...It will rule that out and it's really cheap and easy!

yeah that first!

A lot of people think their carb is junked... then find out the hoses were just old and leaky.... Your carb may be scrap, but rule out the easy stuff first and make sure. When the stock carb is functioning, it's a really good carb and extremely reliable.
