Hi, W4A33 speed sensor wiring. I have the sensor, but without connector... I cant find any pin # on the sensor, but one of the pins are gold plated. Is the gold plated pin +12v or speed signal? Thanks

Hi, I dont drive my car very much, mainly just street legal/drag events. Normally I change the oil and filter after the season, (running E85) but I didnt do it last as I had used the car very little. I ran with it some events and thought I would pull the bearings to check and was surpriced how...

Hi, I am looking for some good cold grip pads to hold at the line when launching with auto. Have read that Brakeman #93 works very well. Who sells these? Thanks

Hi, I have starting wiring the ForcedFour shiftbox on my Evo 2 W4A33 Auto project and would like to measure converter slip as well. This is my first Auto experience, so this is unknown for me. I suppose the difference from engine speed vs input speed from pulse generator "A" is converter slip...

Hi, I am going to get my center diff welded and would like to try doing it myself. I have read splines must be perfect aligned to avoid wobbling. Do you guys make a jig before welding, or how do you do it? There are no shops in my country that are doing these cars, and I dont want to spend alot...

Hi, I have installed Kigglys 6-friction front clutch pack (50% more TQ) and regarding the oem spec for the W4A33, it should be 0,8-1,0 mm. Mine is a tight 0,8 mm... Will it be fine or should I aim for a 0,9 mm? Didnt receive any info in the clutchpack kit regarding clearance, so I suppose I...
