Ok last week a couple of my coils packed it in. After being screwed around by the wreckers I gave up and drove it down to a mechanic in Brisbane running on 4 cylinders. Anyway about half an hour down the highway this red light came on which I thought might've been the engine overheating, but the mechanic told me it was the cat overheating. Got the problem fixed, got home. And the exaust seemed to smell a bit worse than usual, and my brand new 5 inch tip has turned gold (presuming from heat). So have I gutted my cat or what?

firstly, if your cat is gone, you should put up "LOST" signs in local shop windows and on street light poles and the such... but if you have gutted your cat, then don't bother with the signs coz he aint coming back too soon... sorry mate... :D

Lol.. excellent! Try the RSPCA while your at it. Maybe the local chinese restaurants?? Sweet and sour paws... LOL.. :D

For all my chinese friends and associates out there.. :jk:

I wouldnt say youv gutted your cat, but its possible youv melted the bricks/comb and its now causing restrictions

Youll know when youv gutted your own cat through overfueling, haha youll blow half of it out your exhaust and leaving a molten lava state thing on the road :)

Its happened to a mate of mine that had his coilpack die on him

Best (legal) is to get it replaced even if your unsure, or even so, unbolt the cat from the flange and have a look yourself, youll be able to tell the moment u see it

    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
