hey guys

i just installed an avc-r to my r33. but im getting really high boost in 5th my boost settings at 51% duty

and 1.30bar,

all other gears are fine but in 5th it often reaches 1.8 under full load. to counter this i set the 5th gear duty

down 20% in order to control, but its really unstable and fluctuates btw .8 and 1.2 bar?

cheers

Maybe try increasing 5th gears feedback?

will over correct it self? wat have u set urs at?

Have you tried playing with the gain?

gain, as in start duty?

if so i have set 5th gear start values at -20% in order not to reach 1.8bar but it isnt stable and fluctuates btw .8 and 1.2.

Mine was around 2/3 to start with but I actually have them set to around 5 at the moment, with 1st and 2nd gear set at 7ish. I am still playing around with different settings but since i set them higher the car has been sticking WAY closer to its target boost. The feedback as far as I understand is how often it samples and corrects, which (how I interpret it) means it can provide abrupt boost level changes if you have a good external wastegate setup. I have an internally gated GT30R which seems quite lazy about its behaviour, so having the boost controller "all over it" seems to help it build up boost faster then level off better once it has hit the target boost level.

I recommend at least playing around and finding out what works for you, as different things definitely seem to work better for different setups.

      Ceramic turbine damage to engine - what did yours do?

      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?
