CEF11E Posted September 22, 2007 Share Posted September 22, 2007 Where have you people who are using R33 heads been plumbing you oil return pipe from the front right hand side of the head? do you get a "T" peice and blumb it into the turbo drain into the sump? cheers Link to comment https://www.sau.com.au/forums/topic/15420-r33-rb30-conversion/page/279/#findComment-3366938 Share on other sites More sharing options...

CEF11E Posted September 25, 2007 Share Posted September 25, 2007 After a lot of hard work and long nights my RB30det is now in the car. I have spent a few hours tonight trying to get it started and have not got there yet. this is frustrating Fuel pump working - check. CAS working - when i remove it and rotate it with the ignition on the injectors click and the fuel pump turns on everything is wired up bar 1 plug on the AAC valve. the r32 loom has no provision for it. I am still working out the best way to test spark. any ideas? I have had to use R33 turbo injectors and it involved cutting up the original loom and grafting in the plugs but I have done it before for GTR injectors and no problems. the motor turns over fine just does not start when the crank is set to o deg btdc the cams line up with the locator pin marks perfectly. so its fuel or spark i am missing or some electrical gremlin somewhere. if anyone has any ideal please shoot them my way. my goal was to have it running by tomorrow night. so so tired...

Cubes Posted September 25, 2007 Share Posted September 25, 2007 Get a timing light on it and crank her over. Will soon tell you if you have a signal from the ignitor.

GTRgeoff Posted September 25, 2007 Share Posted September 25, 2007 AFM connected? Either that or the timing on the CAS is well out. Try the timing light.

shanef Posted September 25, 2007 Share Posted September 25, 2007 car should start with no afm, it'll just run like a pig and stall etc etc lol it could be that ur battery isnt supplying enough juice have u checked to make sure theres fuel getting to the rail?

shanef Posted September 25, 2007 Share Posted September 25, 2007 also check that the cas plug is actually plugged in properly, not just sitting over the cover Link to comment https://www.sau.com.au/forums/topic/15420-r33-rb30-conversion/page/279/#findComment-3373691 Share on other sites More sharing options...
CEF11E Posted September 26, 2007 Share Posted September 26, 2007 thanks dudes pulled the timing cover off and made sure the cas key is correctly set to the cam key. the afm is plugged in and there is fuel getting to the rail. I am starting to think it is of 2 things. 1. there is no spark. because i have tried advancing and retarding the cas and no difference. and i can hear the injectors pulsing. 2. I have buggered up the injector firing order while making the new injector loom. this wil be a bastard to diagnose and will mean pulling off the plenum again. I will make sure i am getting spark tonight. also battery would be going flat but seems to turn over the motor fine. I am sure it is something silly. it will get there. Also how long should you have to turn over the motor with ignition disconnected to get oil pressure?

r33_racer Posted September 26, 2007 Share Posted September 26, 2007 who knows...pull off your oil feed line to the turbo and let it spit into a bucket for a while and then hook it back up. Once it spits abit out of the line there should be oil pretty well everywhere else. It doesnt take long for it to work its way through the motor.

mr_rbman Posted September 26, 2007 Share Posted September 26, 2007 may sound silly but a similair thing happened to me on my first start up that cubes will remember, haha! It just turned out that my fuel lines were the wrong way round where they connect near the plenum!

HAHAH ive done that before Dash lights are all on when cranking? you can also try the carbie cleaner trick in the TB then crank, if it coughs like it wants to start, then you have no fuel and do have spark.

[200] Posted September 27, 2007 Share Posted September 27, 2007 I have a question re CP Pistons. I know they are off the shelf ones available for the 26/30 combo... Is there anyway that these can be customised to tolerate high horsepower / boost applications? I am going to more than likely get a set with a 22mm pin diameter. I've read that the rings can be moved down on the piston for high boost. Can someone give me some info about getting a set custom made? Also, dry sumps. Has anyone bought a dry sump for the RB30 motor? If so, where did you get it from and how much was it?

Spoolup Posted September 28, 2007 Share Posted September 28, 2007 CP will make one off custom sets to order - the price is considerably more. You must be planning to make an immense amount of power as there are a lot of off the shelf CP's out there making spastic power. I have a question re CP Pistons.
