hay guys i need some advice,

im looking at getting a new turbo for my r33gtst, The car has already a avo intercooler, full turbo exhorst, pod filter, full Link ECU running low boost and im making around 200rwkw on avos dyno.

i want a turbo that has stuff all lag and will give good low down power to mid range no to warried about top end due to, where are you able to use that top end power

so what do people think i will need to get in the power range of 220rwkw.

and will i need to get anything else other then a turbo.

hi flow the stocker i say. best response, cop and epa friendly. 100% bolt on. All the aforementioned turbos may bolt on to the manifold but most will require oil/water fittings. If its a stocker high flow, u can get any mechanic to do it or do it urself. Ie u don't have to take it to a "specialist" workshop that would charge thru the roof.

hey scott

if you want 220rwkw then go for a highflowed of your current turbo, should go same response as the stock turbo

if you want a bit more say 250rwkw then go hks gt-rs (its a gts-t turbo despite the name). it will be a little bit more laggier than your stocker but certainly the most suited to a mild rb25, theres stacks of dyno graphs with rb25 and hks gt-rs

however either way youll need to upgrade the following if you are still using the stock rb25 items:

airflow meter (youll be maxing the afm out)

injectors (youll be running dead on 100% duty or like 5% below at the moment)

fuel pump (it will be running out and can lean the car out, mine leaned out at 172rwkw)

clutch (youll be slipping with 220ish, definetly with 250)

again those arent 100% guaranteed but im maxing everything out at 172rwkw, youd certianly be maxing it out just as much if not a bit more at 200rwkw

      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?
