You may know I recently got an auto 25G, which is normally aspirated. Now I want to eventually turbo it. Over the years I have acquired various bits. I have a turbo, manifold, dump and exhaust, plenum and intercooler. I will get an auto ecu, hopefully, from Rodney.

My WTB list is now a fuel pump, rail and injectors from a stock S1 RS4. I am not sure about the loom. I may need a turbo?

one. I know Nissan are odd. I am fitting an electric tailgate closer to the 25G and its tailgate loom, the S1 loom and the S2 loom are all different. Hirohito's revenge. LOL :)

So if anyone out there has what I need, please PM me.

Also I have read the SAU Skyline thread on conversion but if anyone has any advice for me, like, "don't do it Hugh", I will be truly thankful.

So much for "Mid Life Crisis"

You will need an AFM, stock or GTR bov and some kind of boost solenoid or boost controller.

ATM I am running the simple manual boost controller on the RS4. I would probably go the same way.

you probably wont need an AFM Hugh, on all other RB powered cars non-turbo and turbo use the same part, so i'd say the non turbo stagea's will be the same.

Thanks for that. Saved some cash.

What about compression ratio/head differences/valves? Guess you'll just need to tune with less timing?

R33 guys dont worry about it as long as boost is kept low. I will be using a simple manual boost controller set at 6 psi

      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?
