Ok I have the graph but no scanner but will post it up in the next few days.

Got the car back and @ 17psi it made 199.6rwkw.

makes 17psi @ 3500rpm and its an awesome ride

had it 3 days and the plugs fouled so need to replace em.

Mods are:

RB20DET

HKS 2530 + actuator

GTR Injectors

3" Dump and exaust

650x220x90mm hyperflow tube and fin cooler

hks pod

e-boost

Wolf 3d v4

The response it great and it lights the bags nicely, any questions ask away,

Also I want to take this chance to thank the following people for their help along the way.

SteveSST, Meggala, Summoner, Morgs, DoughBoy and SK. Thanks guys.

Evan

well, at first there was a problem with the coil charge the coils overheated and the car wouldnt start, so they turned the chrge down and now at anything over 17psi the car misfires because the coil isnt charged enough. Looks like i need to gut the cat and sort out that problem. However I am happy and I gotta say the 2530 is a great street turbo, any more would be overkill for the street, well in my car anyway.

im thinking about goin down the same path as you rb20-calais...xcept i want around 250rwkws is this possible with the turbo and perhaps more boost? i rekcon its awsome to have 17 psi by 3500 good work dude.

Michael

250rwkw not possible with the 2530 (a really big MAYBE if you get REALLY FAT cams and a load of head work but then i suspect you'll lose the trademark response of the turbo!!)

well, i once wanted 250rwkw as well. But its just not smart with an RB20.. for reliability and response I feel this is the best turbo to go with. If you want a lot more power you will need to upgrade the engine eventually unless you want to do things twice. Summoner has done this and had awesome reults.

250rwkw + stock RB20 = playing with fire.

Evan

Sly,

Its awesome holds 17psi all the way with my 10psi hks actuator, also the boost comes on VERY quick and i make boost below 2000rpm and it LOVES to flutter, I am very happy with it. The place who did my car did it all and the settings are 10psi, 15 and 17 ... god love SP3!!!

Thanks again I am more than happy with it!

Also Doughboy the 2530 and actuator are awesome and running like a dream together, I must say SAU has greatly benefited me in sourcing great parts off great people!

Evan

Cool bbenny, I cant wait to see!

I think the reason you made more power is because your af got to 13:1 at the top end and mine were steady 12:1.

Got new BCP6ES plugs and gapped them to 0.8mm and miss is gone but is still missing @ 17psi so i gotta regap to 0.6mm, doh!

Evan

with the 2530 (a really big MAYBE if you get REALLY FAT cams and a load of head work but then i suspect you'll lose the trademark response of the turbo!!)

There will be NO loss of response on the turbo with upgraded camshafts. In fact it does the opposite. Thats a fact jack.

in my post i was more referring to the head porting causing loss of response, as how i understand it (btw i am perfectly willing to accept i am wrong) as you port the heads for higher flow, you increase the size of the ports and therefore decrease air velocity at lower rpms which gives less response until the revs get up a bit more.

Rev i am quite happy to be corrected and i never state anything im not 100% sure of as a "fact", (i will always say i think, or i suspect, or as i understand!). Now dont take this personally as im not trying to get up you, but i find some of your responses a bit annoying, even though im pretty sure your not having a go either. I realise that you personally have done a lot of R&D for your 33 and have a lot of info to offer, maybe its just me but i sense a bit of attitude in some of your posts. My name is not jack, it just sounds a bit (ocky to me. cheers buddy :)

    • Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together. 
    • Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open
    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
    • I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂
    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
