Guys,

was wondering where abouts in the SE Melb (around cranbourne) that can do both a compression & leak down test on my R33 GTST? either a feloww SAU member or workshop?

Also would like to know when you do a comression test do you have the throttle open when performing it or not?

Regards,

Darren

Operating temp and WOT.

If you have basic tools to remove spark plugs etc I would just buy a compression tester if I was you. What you would pay for someone to do it u, could of bought a tester & still have cash in ur pocket.

They really are piss to do and then u have a compression tester for any issues or other cars u may need it for.

Here is a very good article to explain the differences.

In short engine compression can tell you whether an engine is tired and a leak down test can show you the engines ability to utilise all of it's compression pressure.

Compression testers can be cheap, leak down testers are not. If you can't be bothered you can go to my workshop. Chasers Motorworks - Eastside Division in Mitcham.

      Lets play a game - What is causing my oil consumption?

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      By Hendasto · Posted

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!

      Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.

      https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
