Hi guys,

As title reads i would like to find out what kind of exhaust i have, it came with the car (r33 gtr). (refer to picture)

Have measured it to be 82mm (so a 3 inch exhaust).

I am also wondering if what i have pictured there is cat or a resonator? Nevertheless it looks very restrictive.

Last but not least, making sure the exhuast (3 Inches) will flow 300-350kw efficiently from other peoples experiences.

are you worried about the brand?

are you a brand whore?

do you one day hope to include it in a vietnamese style for sale thread

where everything is neatly itemised

and you hope to sell for double the regular price

because of SLR photos

new royal purple oil

serviced every 1000km

SUPER MUSHIMOTO ZIEX TYRES

Honestly though. Its really unlikely anyone will know what it is based on any photo you can take. I can tell you its an RSR system, the brand is on the label. The rest of it is alpha numeric and its in japanese, id say thats the serial number which still wont tell you anything about the model or type.

If its 3 inch its 3 inch. If it sounds good it sounds good. Be happy, it came with the car.

P.S. yes 3 inch can efficiently flow up to 350rwkw.

Forgot to mention that cat looks to have smaller flanges than the front pipe and catback section. It also flares up to the cat body, making me confident it has been made by an exhaust shop and not an off the shelf item.

I would say it was done by the compliance shop, and my first guess is that it would be a bag of shit. Buy a nice one that is off the shelf fitment and put it on yourself.

      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?
