First and foremost i just want to express respect for you guys on this forum, if i didnt find this site i would be lost when it comes to working on my car.

Second. I know i could find all the necessary info by searches but i would like to debate some options and decide what is better, so please dont turn this into "DO a search thread"

I guess i should tell you guys a little about me, I live in Japan currently and i have a 1999 R34 GTR Vspec. I absolutely love my car and at this point i have a decent amount of upgrades. I have an Upgraded HKS Intercooler, HKS Oil cooler, Aragosta Suspension, Upgraded Ignition, AP racing 6 piston brakes, Kakimoto Exhaust, Upgraded Intake and filters and thats about it. I am looking for the 500WHP range and would like to get some opinions on how to do that as reliable as possible. I only drive the car about 100-150KM a week. I have just ordered a HKS Dual Plate clutch(my stock one is slipping) the car has 64000 KM on it now.

I just bought a Head and cams that are used and supposedly the head has been port and polished but there are no flow numbers for it, so i need to get a reputable shop in australia to send the head to, to get the head flow tested. I know what your going to say, Why buy a head that you dont know, Well... I got a really, really good price, so in my opinion it is worth the risk.

I would do the work in Japan, but, its hard to get shops that speak english and as good as my Japanese is, its not nearly good enough to explain that i need detailed work done to my car.

Lastly, Yes my car will, and can be dynoed, so i will be putting a Power FC and taking it to a shop, I hope my sign language is good enough to explain DYNO, but ill figure something out because i dont think i can send it to australia for that one as easy as a head, so whatever you guys suggest i will have it tuned.

I think that is it, i really appreciate any help in advance, and i hope that this thread comes up with some great info. Thanks again guys, and a little off topic, but i want to plan a vaction in Sydney next year, any good places i should visit?

Thanks again,

Jason

Sure i can guilt toy, ill send over my Japanese books to you, now all you have to do is study almost non stop for a year, speak fluent Japanese, buy a plane ticket to Japan, and well and thats about it.... In the bigger cities here getting a hot Japanese Girl is about that easy, and the fact that your into Japanese cars like the Skyline actually help, so... When can i expect you?

Hey mate,

Nice car you have :).. In order to make that power and make it all day every day without having to worry about anything isnt that hard as long as you have the cash and by the looks of the car and the upgrades you have brought it shouldnt be hard.

Personally if it were me and you want 100% piece of mind id take it to a mechanic and have the internals changed to forged items. Upgrade the turbos GT-R's are probably one of the cars that have the most turbo options availible to it. Next is the Injectors, ECU, Fuel Pump and id get a oil cooler and filter relocator for wank value.

ECU for that power level a Apexi Power FC would be fine. Install a thicker head gasket.

500hp @ the wheels is a good figure and it will do you nicely. hell GT-R's go hard enough as they are.

skyryn3, thanks for the info, i think those are some great ideas. I was looking at buying a N1 block for about 1500US, i located it near Tokyo so shipping would not be too expensive. I found JE Pistons and Eagle rods for about 1200US. Do you think the Stock Crank for the RB26 could handle 500WHP every day without worrying too much? Also, i like doing my own work, i want to build the car myself(for pride reasons) If i have the pistons and rods balanced, do you think i would have any problems putting the internals together myself, is it that difficult??? If it is, i suppose i would just have them put the internals and the head on and i would do the rest.

2BNVS, Yes i do, but most of them are girls and wouldnt be able to translate very well considering they dont know what a turbo is, i know isnt that crazy? I found some 2530 turbos for 500 bucks, BUT and here is the huge but, the guy that had them on his car, drove the car like he stole it. So i dont know how beat up they are. Is there a shop in australia i can send them too to get rebuilt???

Thanks again guys, i can see my car getting faster very soon.

You can find an amazing amount of answers by using google like this:

"site:skylinesaustralia.com stock crank strength" or

"site:skylinesaustralia.com turbo rebuild shop" or

"site:skylinesaustralia.com rb26 rebuild thread"

(or site:gtr.co.uk)

I'm not being facetious. I don't know the answers to your questions but I know how I could

find them if I spent a few hours. In a day I could probably assemble a pretty comprehensive

plan for such a build, just from these types of searches.

There was another guy living over in Japan and posting on here, he seems to speak Japlish well enough to get HKS to built a motor/car for him.. might be an idea to have a search and track him down as he might be able to help you out and any money that you don't spend on shipping things to Australia and back, is more for bigger and/or better mods :)

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
