Hi, my engine recently dropped compression on 2 cylinders and I suspect cracked ringlands due to the smoke and blowby. I was wondering if someone could have a look at the tune on the ECU and give feedback on it. Thanks.

RB25DET, stock turbo 12psi, Link G4

The car did 10 laps around the track before I noticed oil all through the intercooler piping, no catch can at the time. Did a compression test, 155-160 on all six.I installed a catch can and noticed it filled 1 litre with just hard street driving and one night at the drags. Did a compression test and cylinders 1,2 dropped down to 115, and 130.

For reference here is discopotato03 s tune on e70. From his home tuning viper link thread.

You have more timing than that in certain areas,which I would say is your problem.

    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessssĀ  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feelingĀ  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...Ā Ā  I am about to take the (stock) manifold off againšŸ˜” to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line SetĀ but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave. Ā  Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.Ā  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
