Lawson's 818C

  • Rough weekend in the shop 😞
    • Went to install flywheel, one of the bolt threads in the crank had been damaged by the previous owners so it stripped a bolt. I’ll have to get a new bolt and helicoil the threads. Should be fun in a hardened steel crankshaft…
    • Transmission limited slip diff install went fantastic right up until the point where I found out I need a new transmission. Clearly the monkey with a wrench that built my donor’s engine also rebuilt the trans and they didn’t set the pinion clearance to the differential. So the pinion machined the outside edge of the differential. I also found that a bearing in the center diff had exploded so that was nice. I almost thought I would get away with that one since the 818 doesn’t use it.
      • So basically I’m in for a new transmission. I found a used 04 WRX transmission about an hour drive from me for $300. It has around 75K miles but is cheap since the owner took the center diff off of it, which I don’t need so perhaps this will work well for me.
    • All the time spent on this stuff hindered my progress on getting the steering column and pedal box in the car.
  • Transmission
    • As noted above, diff install didn’t go so well so I’m hunting for a new transmission.
    • Got the flywheel machined.
    • Found out I ordered the wrong clutch because my donor had a 2006 WRX trans swap which is push-type but I may be getting a 04 transmission anyways so I’ll actually have the right clutch in the end (pull-type).
  • Interior
    • Installed the side panel aluminum. Looks like the dead pedal aluminum has to go on before the forward most side panel but the instructions forgot to mention the dead pedal aluminum at all. Haven’t mounted those two panels yet but they’re next on my list so I can move on to pedal box.

  • Side aluminum installed.


  • Carnage!


  • More carnage!


  • Here’s the moment where I look at the diff and though something wasn’t right…


  • The transmissions have convenient ID labels. This is a 2006 WRX one. Supposedly the best wrx transmission for gear strength. Too bad mine was shot.


  • Even more carnage! You can see some exploded metal bits in there.


  • Newly machined flywheel


  • Gave the transmission a thorough cleaning before taking it apart.


  • All the internal bits layed out. Mostly junk now though.
