What makes 180rwhp? My stock turbo skyline was making 193rwkw on 12psi and is a very quick car. How much does the M3 weigh? It is a fairly big car. Both my skylines produced more torque also. In that graph that V8 is making 259ft pounds of torque. My old skyline made close to 320ft pounds and the current one is pushing more than 500ft pounds. I'm sitting on about 700nm and that is out of a small 2.5L 1.3 ton car. And I don't just peak that torque

Stock R33 GTSTs make around 180rwhp. They run 7psi, smic etc.

M3 E36 Evo is 1500kg. R33 GTSTs are 1390kg, so yeah, 110kg less.

E92 M3 is 1620kg.

700nm of torque? lol. Merc C63 AMG BLACK has 630NM.

Yeah. Dyno torque readouts, unless setup properly, are usually completely worthless since the figures are way out.

exactly. i've seen plenty of dyno readouts from small cars that are higher than the quoted figures for v8's and things like the xr6t. there's no way a 2.5L turbo 6 making under 200rwkw is making 30% more torque than a 4.0L turbo 6 that makes 270kw at the fly.

a rb25 making around 200kw would probably be making no more than 400nm at a guess, probably less though.

Yeah you aren't making 700nm of torque.

I exaggerated a little, its closer to 670nm.

What good is a dyno if it can't read proper figures? No one can tell me there is going to be a massive difference from the readout to an actual engine figure. If this is the case, why is the kw or hp anything to go by?. It was on dyno with two people in the car and about 50 - 60kg of led in the boot, two straps holding it underneath and still we were losing traction on the dyno. Tao made close to 600nm on with the same turbo in his car on a hub dyno.

I'm making about 300rwkw.

It’s because the dyno operator rarely dials in the gear ratio/final drive/wheel diameter etc, I've had the same argument with actual tuners before, yarning about excessive torque figures.

But if you get the RPM at which you make the peak torque figure and get the power figure at that point (using the graph) then use the equation [Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)] that will give you your actual torque figure at the wheels.

Or just use this calculator;

530nm according to that calculator. According to my dyno sheet my tractive force is 1340 lb or something at 132mph.

And just because that AMG has that much torque doesn't mean shit. There are a bucket loads of cars which will deal out more power than that mercedes for no where near the price they ask for that car. What is your point? My brothers rotor makes close to 900rwhp cost 30k. You can get a 2jz spend some money on it and get massive power and torque. Doesn't mean shit when you point out the amg.

If the above calculator is right then cool, my car is only down 100nm of torque and doesn't have a engine which probably weighs more than my car.

i believe they are abit of a boat, but in all honesty, change suspension and do ur part in getting it stiffer then that will be gone. then powerrrrr it ;)

As for the camry yeah dw about what he said, u like ur car then dont worry about what people say

However, Aurions is the new model up from the avalon, and is completly different to the camry in power, looks sorta similar, dont misjudge who to run haha, cus aurions are machines

LOL... WAT?

If the engine gets heavier, the car gets heavier... Secondly, the RB engines are f**kING HEAVY!!! My engine that is more then twice the size of the RB25 is around 50KG lighter...

Bloody cast iron crap.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
