I've only heard good things about JUN. In fact I've heard of people making their own home-made cam gears and re-labelling them as JUN, because they look kind of similar. ie, not bright pink and green like HKS which would obviously not be the same as a modified factory one.

Every Jun cam we have had has come in plastic water pipe wrapping and no spec sheets so we may have been getting ripped of.WE got lots of different timing specs from the supplier making dial in real hard and the Springs had very different seat pressures even with the right installed hights, we have replaced all 4 sets with other brands with good results.Please don't ask were we got them from but it makes you not want to not try again.Make sure you get what you pay for and a garranty.

we used jun camshafts in a race car and broke through the hardening after one race went back to dealer and was told it was an oil feed problem checked feed put in new cam shaft and failed before we finished dyno runs,pulled cam out fitted australian cam shaft and have never had aproblem.Had jun cams checked and was told that hardening was not finished properly and JUN dealer just said not his problem and has made no attempt to repay cost of failed cams or labor tracking down problem.i personally would recommend you spend you money on other brands that will stand behind there products.

My mates Drag SR lost its hard facing before it even raced and now has Tomei cams( these Jun cams came in water pipe also with no spec sheet but the sales man is not around any more).Yes i use adjustable gears on HKS cams with sucsses because no 2 engines are the same or reconditioning changes the distance between the crank and cam gears etc.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      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.

      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?
