hey guys i just wanna know how much power you think my rb20 will have with all these mods:

Hiflowed RB20 turbo

Bosch 040

HKS Front Mount

3.5inch Exhaust with apexi N1 catback

CAI with heat sheilded pod

14psi but want to get it tuned for 18psi

Splitfire coilpacks

Tomei Cams

Apexi Power FC

GTR Injectors 444cc

what would you guys expect from 14psi and 18psi with these mods???

14psi... 240-250rwhp

18psi... 250-260rwhp (+ or - 10rwhp)?

Wouldnt be as much difference in the to boost levels as that turbo wouldnt be able to stretch too much further i dont think??

You should have a very nice mid-range with the cams and once its tuned up though!!

whats the differance between the rb25 high flowed and the rb20 high flowed?? wouldnt they just be the same thing once high flowed....like i didnt get the high flowed done (my mate the previous owner did) and it cost him $1650 to get done and i dont know what HP rating it was.

Not 100% on that, i think the rb25 turbos housing is the same as rb20 turbos so once hi-flowed the rb20 turbo maybe more like an rb25 or even a hi-flowed rb25 turbo (dependin on extend of hi-flow)!

Most hi-flows aren't to the extent the GCG 450hp re-build from what ive seen so far!

Well if its the 450hp rebuilt turbo then ur looking 300rwhp on 1 bar boost if ur engines in good nick!!!

Especially with ur cams and a good tune, you maybe able to crack 310-320rwhp again dependin on ur engines condition and if ur happy to run 18psi through it all the time lol

at the moment it running all those mods minus the cams and injectors...on a standard ecu and it runs perfect, but doesnt feel like its all the power she can produce so once i get the cams and injectors in and get the power fc tuned i am hoping to crack 300rwhp...im just waiting on delivery of my power fc from japan

Do remember dyno figures are different for dyno's etc etc

But your car sounds pretty healthy dude :rofl:

Black r32s... theres a few now but cant get enough of them, sexyyy

Yep, get it on the dyno, post up the graph and tell us how you went. There more RB2o's out there putting in good power out puts the better in my book, what an AWESOME engine :Pimp2:

Black R32's are sexy but there are a few getting around where i live at the moment.

The old RB20DET in the R32GTST made 225 rwkw (302 rwhp) with a GCG ball bearing hi flow at 1.3 bar. It had over 1 bar at 3,250 rpm so it wasn't laggy. The only difference to what you have listed may be that it had a split dump and no cat (they are not on your list).:rofl:

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • 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.
    • 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.
