What turbo you running? Is the motor built with cams etc? Thats a good power at 15psi! My car has 270rwkw with bout 21psi on a stock motor with a GTX3071 if your fuel system is up to it 20 psi is no drama!

Put it this way mate my car has 850cc injectors and tomei 276Lpm pump and my boost spiked up to 26.6psi in 3rd gear with plenty of revs and throttle and the motor didnt make a sound it shouldnt of!:thumbsup:

But obviously i wouldnt recommend it on a stock motor! But alot of blokes in here run 20psi on stockas reliably if ya motor is relatively healthy and you dont abuse it too often :whistling:

No ideaonthe turbo but according to previous owner was biggest highflow. Done by ATS

Stock internals as far as i know, no cams or camgears, fuel systemis easly up to it.

Im

Not sure whats good for that turbo but mabye look at a retune orgionaly this car made 236rwkw on 16psi from turbo tune, then jeff gave it a real tune.

ATS, would be GT30 internals in a factory t3 housing machined to fit. Most power you will get out of it is 270-280kw before its out of its range and starts surging or going hyper (aka, spinning n making more boost with no power increase, much like a non actuated turbo) The factory front housing doesnt like boost over 18psi, have seen em crack before but then again have seen em running on 20+ with no problem. Either way i wouldnt push it, if its still healthy, get rid of it and upgrade to something that will handle the power you want with ease.

18psi from an ATS highflow would just be starting to reach the happy zone. I have an ATS "highflow" of sorts, with a GT3076R ball bearing internal wastegate core - front is a stock compressor cover ported out to the extreme, rear exhaust housing is a .73ar AVO unit for the 6-bolt skyline style.

Bill Keen from ATS builds his turbos to take up to around 22psi comfortably, 18psi would be nice and sweet for an unopened motor.

Make sure your fueling is ok, same with cooling. But with 270rwkw currently Id say that probably isnt an issue. At 18psi you could expect 280rwkw, at 20psi perhaps up to 300rwkw.

I use and recommend Bootworx, however Willal Racing is a SAU:SA club sponsor and Martin Donnan would have to be the best tuner in the state.

sorry to burst your kw bubble but i would almost certainly put money on it that 270kw was a happy dyno

Bill rates that high flow to 270,

first thing first go see Martin at >>Willall Racing<< and get a power run and advice on if he can improve the tune or extract more boost

Hey I'm with you

rb25 15psi for 270 is high

Run it on the mainline dyno @ Willal for a more realistic readout

As Steve said. Best thing to do would be to take it to Willall. Get them to do a power run and then look into getting more boost, better tune and see what it spits out. 270rwkw on 15psi would certainly not be coming out of a highflow.

Cheers for the imput guys. Il give willall racing a ring next few days n see how much it is.

Yea even i figured it was a bit much non the less put a massive smile on my face on boost ;)

Just a quick thing the highflow was 2700. Wouldnt it have been better to just get a 3076r or something? I know for the whole stock look its good but this thing is clearly defectable catch can, bov all that crap

      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?
