whilst removing the cam gear cover to check out my cam gears.. i noticed the little pins inside the cas, and the pin on the camshaft that line each other up are broken..

only the one on the camshaft seems to be broken, but without knowing where to line it up with, i beleive its affecting the CAS, and my car wont start... it turns over, and makes a few small attempts at starting.. but it wont start properly..

any ideas? if the CAS was attached to the cam shaft, but not lined up correctly, would the car still start? and how would i go about fixing the pin?

cheers.

Been there, done that.

If you look very carefully at the camshaft side, you can see which half of the hole the key was attached to. You then need to visualise the CAS key matching over the imaginary cam key.

The CAS is also driven by meshing teeth, and it ends up that there is really only one position that the CAS can go back on that will permit the engine to start.

      You have the option to do this. Nobody but me ever did this (go slower, I mean) Everyone seems to fall victim to "This would be a great setup for you, but for me, I need a little more power..."

      Save yourself the headache of an alarm. Immobilizer on the signal side of the main EFI relays so it won't start is good enough. DIY killswitch is the same thing except instead of a nice passive system you need to remember to switch it on and off.

      Yeah, the advent of canbus was supposed to cut down on wiring weight, then some bright marketing wonk says "oh, look at all these wonderful tech gadgets we can cram in here now that we have this wonderous technology" and some arsehole safety legislator says "oh, look at all the wonderful surveillance and tracking gadgets we can cram in here now that we have this wonderous technology" and some dipshit young engineer who has grown up thinking that an extra 500000 lines of code is not a problem because storage is cheap these days says "oh look at all this wonderful shit I can do to one up those dipshit arsholes over at VW" and the Karens of the world all go "oh look at all these fancy things I can do on my screen (so long as I am not driving on a bumpy road wherein touch screens immediately become the single most stupid shit idea ever shoveled into a car) and my 19 zone airconditioning keeps my sweaty fat folds a bit less damp and the windows close themselves because I'm too fat and lazy to wind them up for myself and these reversing sensors would have been great if I'd paid attention to them instead of smashing them on the bollard while I was reversing and staring fixedly forward that day I went to pick up little Charlize from ballet" and the sweaty mongoloids who say "oh this wonderful collision avoidance technology with these 45 excellent radar antennae scattered across the front of my car mean I can tailgate like a methed up tradie at full speed with no fear because the car and the 35 airbags will protect me if it all goes wrong" ...... </shallistopranting?>

      There's a post from a member (can't recall who), went down the path of a twin scroll G30-660 and it's doing over 300kW+ AND comes on about the same as a high flow RB25DET turbo. Have your cake and eat it too in this case. TBH, if I had a 2nd chance of building my car again (i.e. someone gave me what I wanted for my shit box, but the deal was I had to re-build another R33 and keep the change) I would just pop in a stock NEO motor (with new seals, rod bearings, ARP studs, head gasket, sump, Nitto pump), get a smaller twin scroll turbo, modify the stock low mount (keep the divider in place), and make a solid 300kW on 98RON and call it a day.
