My sensor is dead, so i thought i would just spend $40 bucks and get a new one...ha! was i wrong...so my mechanic buddy (i'm stoopid) recommended to convert to carbs.

I'm just doing a single carb set since i got a $400.00 budget.

I can't believe that sensor is $800 to $1200.....

anyway do any of you sell or know of a good deal? I found this on ebay which is just in my range..

what do you think?

You would be better off finding a rebuilt sensor Bleyseng repairs them.

IMHO that carb is the worst thing you could do to your car

i prefer carbs,but a single carb really is not the way to go.
since you allready have fi.keep it.a true carb conversion is not cheap.(cam,DUAL carbs,ect.ect)i have boxes of fi systems.(2.0/1.8/and 1.7)send me a pm of the part you need.ill sell it to ya cheap.(used of course)or talk to
Bleyseng he can fix ya up with a rebuilt one.if its the part i think you need.

Specifically, that SINGLE carb is the worst thing you could do. Dual Webers can work, but a complete used setup will run you $500 or so. Fuel mileage will plummet with an otherwise stock engine (18-22mpg, typical).

There are used MPS sensors out there, and some of them even work. You can also explore aftermarket EFI, which ditches the MPS for a modern sensor ($400-1200, depending on what you get and how much you can do yourself).

Don't give up on the FI. In my experience a good running FI car is far superior to a good running dual carb car. A single carb is a big step backwards.

Get a new mechanic, and a new friend. Obviously he is offering a cheaper alternative to what I gather is an MPS?? Converting to carbs is going to cost you over half of that budget, and a pain in the ass getting it dialed in (add to that cost). You can find used parts that will work fine, if Bleyseng is rebuilding the units - do that.

You can find a good used MPS for not a lot of money (comparatively speaking) - stay away from ebay on those units - just be sure you can test the unit with a vacuum guage and return it if it is bad.

if you continue to follow this thread, you WILL get varied opinions on this topic. But most carb fans will agree, the single progressive is bad.

Most carb fans will also tell you, that without a "carb friendly" cam, converting is REALLY bad....not a simple as pulling off the FI then bolting on carbs.

good luck

So i'm sitting on the fence with no real strong opinion one way or the other about carbs VS FI. I have a stock FI system that ,for now, works great. I have driven carbed cars that ran like crap for whatever reason. So I think this is a preference question. What I am questioning is why the single progressive carb is a "bad" idea for a stock engine?? It worked for VW for a lot of years. I used to have a beetle with big bore kit, ported heads, cam and a single two barrel. Seemed to run really good. So whats the technical evaluation of why lando shouldn't do the single carb conversion? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
