i will take out the boost controller

sorry for f**king with your time then!

for later on just put a new ecu for higher boost .

but to be honest it doesn't feel like it hitting 14 psi but some days it running fine

14.7psi > stock boost

IS GREATER THAN

The ECU assumes a problem when it sees more airflow then its expecting so puts the thing into rich/retard so the car wont feel faster

Quite the opposite actually. I ran mine on 10psi when it had stock ECU thinking it was cool. Then one day I turned it back down to 8psi or so and it felt quicker. I put mine on a dyno at 10psi I think and the AFR's were in the mid/low 10:1 which is far to rich

man, Boost controller means you are not running stock boost!

so what you have to do now is: lower the boost and preferably find a better way of measuring it seeing as you didn't know what it was before.

then if the problem persists come back to us

Good luck

Gap your plugs down to 0.7mm, turn off/disconnect your boost controller, check what turbo you have, if you have a standard turbo then budget for a replacement turbo, if you have an aftermarket one, budget for a new coilpacks + ECU + tune.

Lol.. this thread was a great read... glad I hung in there to make it to the second page.

Wounderz - We all get the shits here when people keep asking the same questions that have been covered 100000 times... All you need to do is search, then to top it all off you don't list your mods and not to be rude but do much about what you are talking about... Its difficult for us to help you when you don't have the basic knowledge.. I get everyone has to start somehwere and learn but start reading the threads and DIY articles..

As said above. remove your boost controller and re-plumb the stock solenoid and see if your bosst stays at a stable 7 SPI... if it does then you can try putting your boost controller in BUT wind down the boost level....

Thats my 2 c....

      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?
