Hey Guys

Just bought a new Carbon fibre cam gear cover for my R33 . Is there any tricks on removing & replacing the factory item with a Carbon one ? Any tips on what to watch out for would be much appreciated :cheers: Tried searching the topic but couldn't find much info on it :angry:

You'll want to reset the CAS position with a timing light after you re-assemble. Also there's spacers in the standard cover to ensure it sits at the correct distance, which is important for the CAS operation. If the distance is wrong you'll kill the CAS so make sure the new one has equivalent spacers or (if possible - i dunno i've never taken the cover off) use the spacers from the standard cover.

Hopefully someone who has first hand experience can provide more detail/corrections.

its pretty straight forward , just mark the cas screws with a pen or scratch before you pull it off and put it back in exactly the same position, should be fine, mine was

Im not sure what spacers hes talking about as cas bolts to a plate behind the cover anyway..

Did exactly what u wrote & all worked out fine with the new carbon fibre cover. The only thing i had to do was drill out the holes on the new cover , to make a little bigger for screws to sit better in. When fabricated they were to small . The washers he is talking about are in a seal which sits behind the CAS , they sit in each corner of the seal in a triangle pattern .

Good to hear , didnt see any washers in mine :unsure:

there was a hep of black sealing goo behind it though maybe the washers were stuck under it

Dare say they would of been ! I firstly pulled the gasket off the original cover & tried to put it on the carbon one. That plan didn't quite work out , so just decided to take the spacers out of it & place behind CAS . Then put the screws into place & lined them up with the marks i made where the screws were sitting before i pulled it off .

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
