can u tell me how an LT8 will run a rb25. I was under the impression LT-8 would run 4 injectors and 4 spark plugs, hence the 8, and therefore only good for 4 cylinder and rotories. I was also under the impression you would need a LT12, LTX12 or LT12S to run a 6cylinder. Clarify please?

Mate LT8 are not just for 4cylinder cars .. I have one on a RB30 Calais .. if you dont want to re wirer u get a Lt12.. all ecu are made for more then the 4 cylinders /..

bump, pms sent, well ICE in Melbourne quoted me $1100 installed and tuned. And they are highly respected in the Victorian section!!!

Thanks for the nice remarks guys!!

PS: The Power FC was just a one off from a friend who was in a desperate situation.

Its best to use a LT12 for a 6 cyl car. You can make some additional outputs run the other injectors and use a LT8, but you don't get full functionality if doing so. In saying that you probably don't NEED FULL functionality of the ECU and they are a good unit.

    • 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...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set 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.   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.  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.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
