32. Cut a piece of sheet plastic to make a plate to cover excess hole from tcu wiring harness behind clutch master cylinder
33. Install clutch master cylinder(may need to trim at the firwall for it to fit)
http://www.subaru-svx.net/photos/files/TomsSVX/32975.JPG
34. Install modified gas pedal
You should now have 3 pedals to brag about.
http://www.subaru-svx.net/photos/files/TomsSVX/32977.JPG
35. Use helicoil kit to tap a proper sized hole for the starter stud to be removed from the auto and installed into the manual
36. If transmission did not come with electronic speed sensor, swap out the one from the auto.
37. Install flywheel and clutch (you remembered to have the flywheel cut right?? And I am sure you also remembered to buy flywheel bolts)
38. Install 5/6mt (Mostly the same as auto removal)
- If using WRX trans disregard the following
- If using a 5mt outside of a WRX trans be sure to follow instructions for swapping the SVX carrier into any 5 bolt side plate r160(found at end of my instructions)
- If using a 6mt with a R160 follow instruction mentioned above
- If using a 6mt with the Sti R180 follow instructions below
- Mark the pinion flange nut with a paint pen
- Count the amount of threads visible on top of the nut
- Remove Pinion nut
- Using a steering wheel puller or harmonic balancer puller, pull the pinion flange off of pinion shaft
- Install R160 flange onto R180 pinion
- Tighten pinion nut back to original mark and thread count
- Remove long mounting studs from R160 and install them onto the R180
- Test fit the R180, and mark where it needs to be notched to clear the exhaust hanger
- Cut the notch and be sure it clears the hanger
- Cut lower strap so that it secures the rear without interference (pic below)
- Install Rear axles into hubs
- Install R180
39. Install 2” lengthened SVX drive shaft or modified 95-99 Legacy 5mt shaft
- For 6mt’s install stock SVX drive shaft
40. If using a WRX5mt or Sti 6mt- Run the two light green wires into the cabin though the hole from the clutch master cylinder. These are to be used for the reverse lights later on. If using Legacy/imprezza transmission, use an ohmmeter to find which wires control reverse lighting by putting the car into reverse and into any forward gear. Find the pair of wires that have continuity while in reverse ONLY.
41. Install front axles and reassemble lower ball joints
42. Install lengthened shift linkage
- You must make your own rear mount for the linkage. Pictured below is a good example of possible methods
http://www.subaru-svx.net/photos/files/TomsSVX/35424.jpg
43. Attach rubber boot to body in order to keep road noise to a minimum.
http://www.subaru-svx.net/photos/files/TomsSVX/34477.JPG
44. Install Custom X-member (may require some grinding to open up bolt holes for proper alignment)
http://www.subaru-svx.net/photos/files/TomsSVX/34340.JPG
45. Connect clutch lines
46. Bleed brakes
47. Bleed clutch
48. Install starter
49. Lengthen speed sensor wiring using heat shrink butt connectors and 3 lengths of wire.
- for 5mt transmissions only
50. Reinstall exhaust system.
51. Reinstall throttle body and accelerator cable
52. Splice 2 reverse light wires from trans to…. 2 wires in line with the neutral wires
53. Place 2 female connectors on the ends of 2 lengths of wire. Plug them into the upper neutral safety switch on the brake/clutch pedal assembly. Route the wires over to the auto wiring harness where they will be spliced into the Blue/White and Black/Yellow wires (right next to each other) This will allow for you to start the car when the clutch pedal is depressed.
54. tuck the auto wiring harness out of the way and be sure it will not fall down
55. Reconnect the negative battery terminal
56. Fill trans and rear with preferred gear oil
57. Start her up and be sure the clutch has full engagement and make adjustments where necessary. Be sure the shifter shifts smoothly into all gears .
Well that’s about it. Good luck and always remember that www.Subaru-svx.net is an excellent resource so if you run into and problems, the people on this forum will be more than helpful in assisting you.

svxfile's rear diff swap writeup for 3.90, 4.11 and 4.44 applications
If you get a limited slip rear differential that has both the correct ratio, and five bolts on each side holding the side plates on, go ahead and install it.
This however has not happened to anyone I have heard of.
If you get an “open” rear differential, with no limited slip, then you have to convert your new open differential to a limited slip for two reasons. The first is so that your svx axles fit, and the second is so that your power doesn’t go up in wheel spin.
What I do is to use the replacement rear end housing, so that I would not have to mess with the pinion gear, or it’s preload.
Use the ring gear from the new rear end, but use the side plates, and carrier from the svx. You will have to do a little grinding on the left side of the housing opening, where the two humps are, so that the ring gear from the new rear end, and now mounted on the SVX carrier will clear.
You MUST use the longer bolts from the limited slip SVX rear end to mount the 4.44/4.11 ring gear to the LSD carrier.
I use the shims from the SVX housing but you have to check the backlash, and pattern before you install them into the car.
