was that is the same form of tune?  about 95kw drive train loss

Oh, and gotta say it, 331rwkw with stock RB25, ~20psi - gotta love HKS turbos :D

..hang on, didnt that engine have cams and greddy plenum?

your point is?????

Just trying to get it clear in my head how a GT30 blah, blah compares to the HKS 3037. They always seem to be a few kws ahead, but the cams and plenum make it hard to be sure

I think before the cams Steve's R33 made ~250rwkw on 1bar with the .69 exhaust a/r.

Twin 3037S on a GTR has made 700rwkw. Obviously big cams etc.

But still quite respectable power.

The you consider the HKS 2835's that make up to 280rwkw on the RB25's.

LOL...but the the 2835 owner will wind 1.4bar into the strd RB25 to see what it will do...and many of the gT30 owners seem to pull the pin when they get to 1bar and 250-260rwkws

correct, obvious that a car has bolt ons if its making over 300rwkw. But it didnt have larger capacity engine (RB26 internals) or port work - just bolt ons.

oh, and Joel, it made just shy of 260rwkw with a restrictive exhaust at 1 bar with a 0.63AR turbine housing, before the cams - that was with a 20 odd minute Martin Donnin tune, he just did a rough tune to keep it going until it was sorted (other mods added)

Interestingly, it only made 270 odd at 1 bar with the cams, but the CR was lowered to 8.6 to 1

remeber this is an Autosalon dyno result too...

Ash we need more info.. Was it also a DD dyno or another type?

I just find it a little hard to believe an RB25 with GT30 achieving 369rwkw :P

more will come when i can scan the graph, it was a mainline dyno.

i suspect around... 20rwkw higher at a rough stab as i have 330rwkw a day before in the all hailed shootout mode on a DD dyno

was that 330 on ben dyno? What psi were you running and what fuel?

Did you have head/valve/valve spring work done when the engine was getting rebuilt?

    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work 
    • You can just get the injector bosses, which allows top feeds to fit. He can use the same injectors without issue, like these (another option): https://rocketindustries.com.au/af59-2210-rb25-fuel-injector-inserts     The Racework ones look a bit better: https://www.nzefi.com/product/raceworks-lower-injector-mounting-boss-kit-for-r33-rb25det-s14-s15-sr20det/   You could also just get a similar kit like the Radium one by Plazmaman: https://plazmaman.com/product/nissan-rb25det-r33-billet-fuel-rail/?srsltid=AfmBOoogfYq49X0fu2Wdbf8yOf6zt9egyPAif_gn3Qr3G8hzAphhTgOkO70
