where the hell do i find, a good 2.0 MPS..... Options

[bd1308]

PP has them NLA, so i am sure AA has them NLA too.....i did see them one time offered at over $1000 and i KNOW i dont have that kinda money...unless i sell my stash (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif).....of computer stuff.

So, where do i get/rebuild my MPS so i can get back on the road without putting along with the damn car running rich.


I just want to thank you for helping me solve this puzzle.....this is it....i remember now WHY i replaced the hose from the MPS to the plenum in the first place.....i thought it was a vaccuum leak in the hose, which got worse, I thought it was a fuel filter when it was the MPS/Dizzy at fault.....

I *DO* have a 1.7 MPS......would that work okay or would it be way too lean..?

I read from my BOSCH fuel injection book that if you unplug TS2, the engine will run more rich....but IIRC if you unplug the CHT, it wont run at all.....so is the book referring to the intake air temp sensor, and could this possibly come close to offsetting the lean condition caused by the new 1.7 MPS ???

I'm just tossing ideas around. This condition is getting progressively worse now though.

You'll note that I didn't say it was impossible, just impractical. The cost, as Mueller pointed out, of working up tooling and materials required to make new diagphrams that work EXACTLY like the stock units do, is too high to make it economically worthwhile. His $300 estimate may very well be LOW, and that's still only the diagphram. That doesn't include the cost of actually rebuilding and recalibrating the MPS with the new part.

If concours quality 914s ever become desirable enough, and expensive enough, then someone will eventually make these, at a very high price. People happily rebuild MFI injection pumps for $1500 a throw. 5-10 years from now, I'd guesstimate a rebuilt MPS that actually works may be sold for a similar price.

Now, the clever thing would be to make up an ECU kit that hid entirely inside the stock ECU housing, and hid a modern solid state MAP sensor inside an MPS housing (so there are no extra hoses). Now, you'd have a stock-appearing setup that would be enough for a concours judge that worked, and was repairable using readily available parts.
