      my mk1 rabbit is swapped with a 2.0 16v from a 93 passat. im about to put on my new set of webber 45's what kind of work do i need done to the head to make it run like the monster i want it to? expense is not an issue at this point. all the work that will be done includes" entire gasket and seal set for block and head new water pump and low temp thermostat, high compression pistons and arp under cut head studs, venair silicone hose kit and shocktherapy wires set. swapping out the 4k tranny for an 020." basically the entire power house will be new. im trying to get all of this done by sowo and any knowledge would be much appreciated.

      #1 a 4K is an 020. 4k is the trans code
      #2 if cost is not an issue, dump about $10,000 into the head in porting, cams and valvetrain work.

      Is that even possible? 10k into a 16v head. cams port and polish retainers hd springs. thats maybe 3k done right.

    4. 03-07-2012 05:19 PM #4
      keep dreaming. a good, flow matched, port alone will be close to 3-4k. no hardware included.

      by the time you factor in all the hardware, there is at least another 2-3k. (cams, oversized valves, etc..)

      Fueling and induction, An extrudabody 16v ITB set-up is 2k, without injectors.

      now that we've gone through that, what is your REAL budget.

      What you will need and lots of it: time, its as simple as that.

      Unless you bought your carbs from a known working setup your not going to make it to sowo unless you spend everyday working on it all day. I had everything ready all parts in and everything, planning on having it running in 2 weeks, which turned into 3 months and is still not running and I finally gave up and am turning it over to a shop. I started on Dec. 21st and I don't even think ill make it to sowo

      ive already got my cams ti retainers and hd springs, i went with a tt set of 268 272. i have all the linkage and everything needed for the carbs setup. all i really need to do is send the head out "because there is not one machine shop in the area that can do it" and get the valves done port and polish. i just dont know if i want to send it all the way to oregon to get it done.

      thats too bad you werent able to get it running right. one of the reasons i mentioned to give me a call was to go over all of the things that you are now dealing with so you could eliminate alot of waisted time. anyway, i can understand wanting to just get it running finally. i can almost guarantee however, that you will still need to make some jetting changes after getting it back. it seems that the main problem is it running lean at times so make sure to have all this checked. timing ( too much advance ). high mileage used carbs that leak at the throttle shaft bushings. an air leak with the soft mounts or the intake at the head. too little fuel pressure. the jetting in the carbs is wrong and if it seems to run fine but your afr #s are still lean, you may have an air leak in the exhaust before the sensor, and or the sensor isnt calibrated correctly or bad. anyway, let us know when you get her back.

      ok so i got my 6al blaster coil inline fuel pump 2.3-3 psi. and ordered the light weight flywheel and clutch kit from bfi for my new 020 CHE. and a mk1 rad. i want to run as clean and simple a set up as possible. i want nothing really showing in my engine bay. im going to run what wires i do need through the drivers fender using a piece of conduit. but im still kinda lost on what wiring i do need. do i need to keep the jet tronics stuff or can i run off the msd by its self. this is my first rabbit and my first carb setup. i refuse to cut corners and want it to be right the first time. any help advice criticism (constructive that is) would be greatly appreciated. im trying to learn this and more then willing.

      Have you had the carbs jetted and synced yet?

      also, you do not need the OEM wiring.

      I got a bigger and badder 16V on Webers and it was able to start and run well on the vanilla jets from the factory. I have sinced upped the idle jets, still need to do the main jets but still out ran an Audi TT 180. This to say you should be able to get it going on the vanilla jets without much problem. A good linkage with dual throttle cables is a wise investment. Weber makes one but the Magard seems more robust.
