  1. I could be interested with a small caveat : I live on the other side of the planet. Taking into account what you'd want from it and arranging transport, I might not be that interested after all.
  2. Same boat for me, I snatched a G30-660 supercore for my RB20, still trying to decide between .61 and .83 A/R, I was vouching for the .83 but the comment of geoff about the G series liking the small A/R more is confusing me.
  3. Have an RB20 (currently sitting on a shelve), revved it to 8200rpm for around five years and it wasn't happy past 8000rpm but still pulled so i was using it past 8k regularly even if you could hear mechanical noises coming from the head. I don't know if it was the lifters not happy or valve float. I'd bet on the latter. Decently sized higlflow turbo, 630cc injectors... just basic power upgrades and 20psi boost on E85 so nothing crazy. A small chunk of a valve on the exhaust side decided to retire itself from the workforce and fly through the neighboring cylinders and the turbo for a better tomorrow. Installed a broker motor and kept the revs to 7800rpm with the same setup, miss the 400rpm a little as the limiter is much more present, but motor didn't last long and wast extremely extremely rusty in the cooling jacket. No graphs on E85, but I have one from the first motor on pump 98, 14psi/0.9b and stock airbox that showed 198 rwkw and 320Nm of torque. And the topic for RB20 dyno already exists so go find some graphs. Stock limiter on an RB20 is 7600rpm, it's plenty enough with a good and decently sized turbo on it, don't go too big as the 20 quickly becomes a dog down low. 7800rpm was a nice sweet spot for me but my turbo was waking up late. GT28 based turbo (2860RS/X2863) and the like, mid boost, stock limiter and enjoy. Street fun, decent power and powerband, reliable, can serve as a daily. I'd say install springs in it i you want to rev it past 8k, especially with more than 12psi/0.8b of boost for peace of mind. The crank was decently balanced from the factory so not much to gain from that side, but mass from the rods and piston are a little all over the place. If you plan a refresh you might try to even things out on that side.
  4. I'm surprised the cams and crank seals didn't let go/popped off already.
  5. It definitely does look like a g30-770.
  6. G30 turbine flow : G35 turbine flow : The compressor flow chart : 770 : The 900 one : and finally the 1050 one : All were taken from ATP website so I consider these as legit but still take these with a grain of salt as they were not officially released.
  7. I'll post everything i managed to squeeze out from the ATP website in a few hours.
  8. I got it from ATP when they were updating their site with the g30/35 to come. I managed to save all the compressor and turbine map from their site for the g30 and g35 but the g30-660.
  9. Awesome result ! A friend is thinking about stepping up on his SR. Can you give me some details about your setup or point me to your topic where you present your setup.
  10. Some EV14 are even cheaper than that. Got 6 630cc EV14 for ~80$ each. These are stock injectors from some porsche 911 turbo or GT2 or something so pretty cheap and readily available.
  11. Nope i just retrofitted intake camshaft and pulley from an S1 RB25 on my RB20 (coming from a R32). I drilled and taped the camshaft cap to install some kind of banjo fitting through the cam cover in the cap , a solenoid and then back to the head through the cam cover again. The solenoid is operated via the nistune ECU. It looks sketchy but it's working and not leaking so far. I'll give some pics for you if you're interested.
