      Looking good man, that windshield looks real good too...

      Fabric dye can work, just need to spray, let set, brush, retreat, repeat.

      should i caress it and whisper sweet nothings to it to soften it too, RSZero1?

      New shoes in...






      Gotta find hubcentric rings for it. I don't want the lugnuts to take the load of the wheel.


      Finally got the wabbit out of the driveway under its own power. The six puck solid center clutch and heavy duty pressure plate (with a lightened flywheel) coupled with an extremely touchy gas pedal made for interesting times getting out to drive. A number of stalls. Didn't help that the car is untuned.

      Anywho, I did my parade lap around the neighborhood block...in 3rd gear! My shift linkage needs to be adjusted. Any tricks? I can only get into reverse, 3rd and 4th. 1st gear only if I detent the shifter just a bit and pushed forward. It's a matter of adjusting, i know.

      Wabbit started running on three cylinders again...same cylinder...my guess is the fuel injector again.

      Gotta say...felt weird driving the thing. I bought this basically as a shell...and only now, after eleven years is it moving under its own power.

      why unsprung clutch if it's a street car? how light of a flywheel?


      i don't understand this, my clutch is good for 575hp and pp for 600 ft.lbs...sprung, organic kevlar and ceramic kevlar. 14lb flywheel.perfect.


      get rid of the unsprung clutch man

      Ideally, I'd rather have a sprung clutch. However, back when I bought my clutch and pressure plate (many years ago), I had a hookup for an ACT clutch/pressure plate package....all they had was a solid center setup. Plus...my tranny is a 4k 020....back then, there were not many good clutch packages that could handle higher hp and tq setups, whether it be sprung puck or kevlar.....thus the solid center six puck setup I got.


      Lightened flywheel... I have no idea. It came with the parts car I got (again...many moons ago).

      Today I pulled the clogged injector out. It had some copper-colored metal crap stuck in there. Tried purging it out. Then the fuel injector didn't want to pulse anymore. Took it to BFIC, a local fuel injection/carb place and they tested it. Said it was DOA.

      So now I'm looking at getting 60lb high impedance injectors.


      In other news....

      Finally got the horn working. Was at Harbor Freight and decided to get a Wolo horn...why not? With the momo adapter and detachable wheel hub, something was not connected right for the ground. A little bit of fiddling around, viola! Horn works.


      Headlights were an issue too. They weren't turning on. I wired it as per the wiring diagrams on VW. HOWEVER... my EZ wiring fusebox is GM based so I had to figure out how they powered certain things. Turned out the 12v wire that led to the headlight switch had to branch out and connect with the hi-beam switch wire as well. And let there be light!

      That is all....for now.

      Been chasing odd oil and coolant leaks here n there. At first thought it was the screw on oil filter base, but turned out it was one of the oil cooler adapters to the thermostatic adapter.

      I was previously only getting 3rd, 4th and Reverse. So I used the cassette trick to space out the shifter...actually i used part of a cassette tape case to space it out. Worked great...now have all my gears.

      Tuned the 60lb injectors for a somewhat steady idle and took the car for a spin. I turned on the Autotune function on my ecu. In first gear, it was very jerky but after about 10 minutes of driving, things smoothed out.

      Driving a solid centered 6 puck wasn't so bad. It will chatter a bit if I don't give it enough rpms, but it's very manageable actually.

      Was able to get it on the freeway for a bit. Still low throttle. When I got to the hill towards my place, I decided to give it more gas and that's when it all went downhill from there.

      AFR's went straight down to 10, then to 9. Smelled a whole bunch of fuel. Was able to pull into my driveway. Turned out the fuel injectors unseated from the manifold. Now I need to reinforce the fuel rail mount/bracket.

      Tomorrow afternoon, I hope to cut off the crimped db37 and solder the db37 pigtail I made to the existing harness .

      Meanwhile, I decided to test my ecu with the jimstim to see if RPM's would read. Oddly, it wouldn't. WTF? It was working before....

      So opened her up...



      Somehow I didn't solder the jumper from IGBTIN to JS10. IGBTIN was soldered to the R26 resistor....I can't remember why?

      Anywho... fired her up on the jimstim and now have RPM control again.

      Tried again a few minutes later and lost RPM control. WTF? A lil further detetective work revealed that my ground wire near the proto area came loose. Resoldered it and now all is well on the jimstim ecu testing.

      Will report back when more work is done...

      more pickchars!!!


      Wanted the quad light look but the inner driving lights wouldn't fit bc of the intercooler being in the way. But a fellow vortexer had some mismatched fog lights in his stash... got me thinking...

      I could mount them on the bumper OR...



      Not everyone's cup of tea, but I dig it...that's all it matters, right?

      even more pickchars!!!!

      I wanted a speedo...but there really isn't much room for a speedometer with my cluttered cluster. I also wanted something fairly cheap...

      read on the web that some folks use bike computers as speedometers which got me thinking....

      sigma bike computer, magnets, brackets, telephone coiled cord, connectors...


      bike sensor on bracket


      rare earth magnets epoxied to cv flange washer



      couldn't run a wire through the column. then got an idea from some motorsports pics (using a coiled wire)








      It's not the most elegant solution but at least now I can read my speed. The bike computer can be lit at night pressing two buttons.


      Took the wabbit for a drive tonight, and idle is still a lil rough. I'm thinkin probably vacuum leaks of some sort. On my boost gauge it doesn't seem to be making positive boost pressure. Something's up. Gauge does move but it moves from vacuum to zero but that's about it.

    13. 03-22-2012 10:18 AM #63
      You know, VDO makes bike computers too.
      Theyre pretty cheap as well, got one myself.

      Would really fit with your whole look.


    14. 03-22-2012 10:55 AM #64
      rocked the bicycle speedo on a street fighter i built a few years back, worked mint. what kind of epoxy did you use? looks like you might have a hard time keeping that magnet on there with the exhaust heat and oil/debris. interested to see how it works out!

      Love the build so far!

      Why didn't you mount the speedo sensors at the back wheels?
      So it would give you correct speeds even at wheelspin

      Personally I would look at a GPS that would fit in the dash as it shows the speed as well.

      thought of a gps but already had the extra bike computer laying around.


      I've got a good oil leak of some sort. dunno where it is coming from.

      i bypassed the boost solenoid and now it's just running wastegate. maybe will see some positive boost pressure.

      So I had been having problems making positive boost. Long story short...it was a bad wastegate spring.



      Suppose to be a small tial red spring...but something was messed up. As soon as I got on the throttle, my wastegate would immediately open, sounding like a nasty exhaust leak. No positive boost.

      Pulled wg signal off wastegate and ran just only spring pressure, but only saw 5psi tops. Something was up.



      Got a new tial big yellow spring (something like 11psi I believe).

      Yeah...the red spring...something was up with it.


      Anywho...after lots of swearin n cursin, I got the new wg spring on. Got on the road and woohoo!!!!! Got 10-11 psi of positive boost. Now it's starting to get fun.

      Sad news...my rear brake pads are gone....gotta get new cheapo pads.

      not much to update....took the wabbit up angeles crest hwy and had some fun in it.... noticed that as I went WOT, my fuel gauge level would drop alil bit and as soon as I was off the gas, level would return back to its spot.

      Thanks....unfortunately, i have a small wiring issue right now.

      Sometimes the fan stays on (it has no after thermo run switch) and the only way I can turn it off is to use the battery disconnect. My fan override sometimes doesn't work either. The wiring gremlin is located somewhere in the engine bay.. that much I've localized.

      Waiting to turn up the boost....when I come back from my roadtrip with the bus.

      No problemo. Hopefullly it helped you out with some ideas.


      So now.... I've been trying to get the boost solenoid to work within megasquirt. I had a couple of issues mainly in that the solenoid wasn't powering up.

      Got that sorted but solenoid wasn't still clicking.

      I had wired the the solenoid to SPR1 and JS0 (IAC1) so I thought that the wire to the solenoid would be the #25 IAC1 wire. Nope...nothing. So broke apart the DB37 connector and soldered a wire to the #3 pin (as depicted in the msextra manual). Ran that to the solenoid. Turned everything on and now everything works.

      Been tuning it in open loop and am boosting to 15psi. Now just fiddling with the tables to get the most for that pressure. Probably won't be going past 16-17psi since I'm just on double headgaskets and STOCK headbolts.

      Yeah...stockheadbolts. I do have APR headstuds but that's going on my 2L 16v IF this 1.8L goes buh-bye.

      The wabbit is heading to the dyno in two weeks. Hoping for at least low 200's at 15psi.
