My R32’s previous config was setup as a Targa car, roughly 300kw @ the wheels using a pair of GT-SS's and some supporting mods. It was time for a change – my new setup is focused on track days.

The 2.8 doesn't make it spool quicker a lot. But on road it feel not that laggy.  Maybe adjust the cam gear will help the spool.  

Dial in more intake advance and pull timing out before 5k to get the turbo on faster.

Yes. Will adjust both cam gear next month. At moment both cam gears are untouched.  The strange thing is my reimax cam gear does not have any degree mark on it:(  it might make the tuning a little bit difficult.

Curious to know why you would think an engine like that wouldn't live with 500rwkw on a daily basis? the power is all in the right foot and the boost controller

We have been making 450rwkw+ on a stock block and crank for years no issues. Your combo should be good for considerably more on a regular basis

It's not that I don't think it will, i just don't require that much power. I haven't really had a chance to open the car up to it's' maximum potential so it just seemed like a no brainer to turn it down for now. If i decide later on that it needs more go, i can always have it turned back up. 

For me, it's fast enough for the moment, so my theory here is that less power should mean less stress on components. My right foot is little bit scared of the power.

The other thing worth noting is the diff gearing has been shortened (4.375 ratios), so the car really moves. I can drive it around in 5th no problem and still have enough torque to pull from 50kph. In summary; it seemed fast enough.

That's fair enough. I guess all you need to do is ask the tuner to turn the boost back up ;) we run an old Link G4, no +, and our boost is controlled through the ECU. Turn the air con on in our car and it doesn't loose power, it gives it another 15psi of boost :P 

You should try some 4.9's ;) We use them for drag racing but on the street they are insane. You runs out of puff pretty quickly though. Its an RB26 S14 hence the reason we can run such a ratio.

Wait 4.9s? That's going the wrong way for my preference. :1_grinning: That must be insane... Mine tops out at about 240-260 at the moment (i can't be sure), it was doing it pretty easy at a track day (til it broke, thanks igniter!)

I do have a switch for high boost, but low boost seems mental enough for the moment.

Yeah you read right, 4.9s ;) We use the 4.1's normally but swap it over when we race it. If it would get off the line it would run some decent times but it does trap 138mph all day every day :P

 

Live life a little, run high boost :D 500rwkw is fun!!!!!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
