ok guys my project 32GTR has come to its end nearly!

look out for it cruising the streets of sydney, number plates - - - URWSHN - - -

mods are as follows:

stock block - hot tnaked

new 33gtr crank

cp forgies 20thou over

stock rods, forged, linished, balanced

acl balck face bearings

arp rod bolts

oil stoned deck

new genuine nissan head gasket

n1 water pump

n1 oil pump

oil restrictor in head

head cleaned slightly

stock cams for now, will get poncams when motor is run in

cleaned up stock plenum

100mm cooler

044 in tank pump

sard reg

sard 720cc injectors

splitfires

iridium plugs - gapped to .7mm

power fc

adjustable cam gears

twin garrett 2860r-5

z32 air flow meters

oil cooler

stock b.o.v's

tomei baffled sump

car has previously run 11.70 with veyr little mods.

looking at running 22-25psi on shoot-out mode with some avgas added to the fuel, up the octane!

im hoping for 400rwkw, but i think these turbos will be my downfall! see hwo we go!

so let me know what you think, or how you reckon the car will go, and similar power figures maybe some of you have had!

cheers to all that have taken the time to read about my project! and if you see it cruising around flash ya lights whatever!

hope to see some of the fellow sydneysiders out at wsid when i go for the 10sec pass, on cruises, track days and at shopping centre car parks! hahahha yeah right!

see ya later all.

thanks

330-350rwkw. Stock cams will be your downfall there and will limit you around that point.

After than, you wont get over 400rwkw on PULP. Probably 370-380rwkw, could be a bit more. Depends on how happy the dyno is really.

Dont use AVGas. Just use a properly designed fuel like Sunoco, C16, Elf Turbomax and the others that dont come to mind

If you do use decent fuel, you should be able to make 420-440rwkw with as much boost screwed in as you can

So thats my bets in. Pretty general, but its pretty much what everyone else is making, so you shouldnt be a lot different in that regard

And btw - drop your sig size, its waaay to big (check the forum guidelines for sizing) :pwned:

I've heard there is unleaded avgas out and about now if you can find it.... I was thinking of running it for the next tune...

I'm not too sure the stock bov's will handle much past 15psi and may leak. :cheers:

To quote someone famous:

Avgas is designed for aero engines that turn over at a low rpm setting at constant speeds for hours on end. Not for an RB26. Use the proper fuel as it will burn better & generate more horsepower.

What rev limit you using im worried about pushing mine any futher then 8500rpm with the N1 oil pump. i think with cams you can run 360-380rwkws you will not need more for the street, if you need more for the Drag track just add 50-100 shot of NOS. And invest in GTR gearboxs HAHAHA

As for current power 315rwkws at 20psi my guess

Stock GTR BOV's are good for over 600rwkw.

They are good for a measly 15psi with small twins :D

Why are you guys having a go at him? Sounds like he's doing this to get a 10 second quarter mile, not to get 400rwkw.

I think you will get it, the 10 that is. Dunno why you wouldn't put cams in while building the engine though.

Its definatly not impossible to make 400rwkw on pump but it will cost you - proper head and chamber work

done by someone who knows there sh#t, def cams and possiblly valves only said valves cause

thats what it took for us to make 435rwkw (98) and made it on more than one DD dyno.

thanks for everything guys, at the moment im not changine the cmas on the run in tune! just wanna drive it. and yes i wanna crack the 10second barrier in my GTR. as for the rwkw, just easier way to measure power i guess, against other cars, cause not many cars will be keeping up with it around a track or on the old pac! hahaha!

nah im sure there are other fast cars out there that will probably beat it, but thats fine.

as for racing on the streets, nah dont do that, my dad would kill me as he builds drag cars for a living! so to answer it no i dont race, but i give it a squirt here and there! nothing crazy!

sounds good about c16 i think, avgas was my question as i could get it readily from a good friend of mine, and i work in the aviation industry!

as for the power figures, i was guessing 380rwkw with cam and c16, but if it gets more beautiful! and if it doesnt run a 10 second 1/4mile time, ditch them turbos and put the big single on, just to run a 10! keep the twin set-up for track days etc!

thanks to all for comments and advice, appreciated highly!

but cams will be done before the big tune... only going to use the poncams anyways! so it aint that big of a job is it?

cheers guys i will try and post some pics up soon if i can get them to load without being to big!

thanks once again!

garth how u goin dude...

u will get high 10 second passes with the setup u got now..

it was my car before and i was passing the line at 119.9 mph... with shithouse launches due to not wanting to break the box.

this was with only a clutch, dash 5's, and boost, still retained stock ecu and fuel system and mount, and obviously an exhaust

119.9 mph is pretty close to a 11.0 pass, that was with 19 psi screwed in..., with afew more psi, you wont have a problem catching 10.80, i recon...

only if u can drive it like me...

lol

speak 2 u soon dude.

denis.

      R32 gtst speedo out by 10kph

      By -Jimmy- · Posted

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .
