G'day!

Thanks Jon! Do you guys meet up often for cruises? What ECU's do you guys usually run over there? Are there lots of tuners? What's the highest octane pump petrol available at gas stations? I've always wondered what the car scene is like in North America..When I picture it I think Fast and the Furious :P

yeah alot of meets/cruises both on the east and west coast.
as far as ecu's
most people run stock(ROM tune), the uneducated run power fc's but the smart people who love their cars run haltechs.
i think compared to the population we have more then enough tunners tbh, not to many good ones in the Toronto area but there are 3 or 4 .
and highest octane is Sunoco/petro-canada 94 but just as many people with JDM cars run shell v-power as well.
ps. what does "under offer" mean?

I've been told to look into the HX40 Holset turbo! Somewhat same size as the GT35 from Garrett?

They do a lot of diesel engines and truck turbos right?
Here's a vid of a short squirt in my R32 GTR that I found tonight :P

I just asked my friend who has an R33 GTST and he said he's running a HKS GTRS for about 340rwhp. Another option he said, if you want more reponse, is the slightly smaller HKS GTSS.

I will look into this GT28 and also the other recommended Holset turbo!
Thanks

Not too sure about the RB25's as my R34 GTT was only stock with exaust/boost controller/piggy back etc pushing out around 250RWHP. I know a lot of the Silvia boys run Garrett GT2860RS on their SR20's, also known as the a "disco potato" They offer around 350HP with near stock-like response.

Ahhh. Those should be a little laggier than N1's but should be able to handle more power. Yeah that should be good enough to keep oil temps down. I set the warning light and sound for 110 deg Celsius in my car. Any more than that and it gets risky. To push those turbo's to their maximum potential, you'd still be looking at an upgraded fuel system which could cost $$$, depending on how much you DIY

That 5 laps was on a fairly long track (~3.00 min lap time) on a 40 degree Celsius day

Sorry I made a mistake on the turbo's I have. I thought N1 amd Nismo were the same lol.

I have "32Nismo (14411-06U00)" in this chart http://homepage.ntlworld.com/tbroom/Turbos.htm I have A/R.60 on the front and .64 on the exhaust housing.

They say there rated for 600ps. Im not sure if they can handle that now. I sure wouldn't want to try anyway lol. I forgot to mention I have a earls 10 row oil cooler. I remember being on the track last year, and oil temps were crazy high. I remember reading how bad the R32s heated up quick but I didnt think after 5 laps it would be so hot.

Hey, don't leave the GTS guys out.
What about us RB25 guys!

Cams/camgears also beef up the mid range quite a bit when you're making around those power figures. If you're on a budget, cam gears can be had for a few hundred $$ and make a substantial difference

The main cause of stock turbo failure when running high boost are the ceramic fins. N1's are pretty much standard turbos with steel wheels instead of ceramic. The advantage is you can run a bit more boost. N1's are generally good for around 400AWHP. I've been running 19PSI and making 450+HP for years and haven't had any head gasket problems. The first RB26 that blew in my R32 was due to a spun big end bearing.

Oil issues are the RB26's Achilles heel. The problem isn't inadequate flow from sump to head, but rather the other way around! At high RPMs all the oil is pumped into the head and it doesn't return fast enough. I can't count on my hands how many RB26's I know have gone due to bearing problems.

At 14.5PSI, I don't think you'll see 450AWHP; even on a RB26/30. Pretty sure R34 GTR's run stock around 1 bar with the boost restirctor removed. With an unopened bottom end, most people run around 18-19PSI safely. I'd probably speak to your tuner to see what he's comfortable with tuning. Many tuners here outright refuse to tune a car to a state which they think is "knife's edge" or unsafe.

If you're planning to track your car, I'd definitely invest in an oil cooler and a quality oil temp gauge. If the oil overheats and gets thinner, it will only worsen the oil problems. I ran a stock radiator on my R32 without any dramas. The reason I had to take a break after about 5 laps was because of oil temperature, not water temp!

For turbo's I have a pair of N1's. Those are similar right? I should have thought of this earlier but its probably a good idea to get a metal head gasket instead of the OEM one I have. What do you think about that? Im concerned about setting boost to high and blowing out the head gasket. I also bought a brand new set of OEM head studs. I read many people have used OEM studs with high boost and have been fine. I was thinking about running 10psi low boost and 14.5 high. I have a fully rebuilt head with stock cams. Bottom end is stock.I would like to change out the oil pump for a Nismo or N1 unit same for the water pump. Do you think its safe to run that boost on a stock bottom end? The car will be mainly for track use.

What's your cooling setup? I had a big problem with over heating the first year I owned this car. So I want to make sure cooling is one of the primary things to take care of. I have a A/M 3" rad with two 12" e-fans. I want to get the Nismo air separator and a low temp thermostat. I think temps should keep in check with that. Again what do you think?

Thanks for the kind words guys It's KV2 Athlete Silver.
Yeah, if you're chasing a good, responsive track set up around 450awhp, I'd definitely recommend HKS2530 or Garrett -7's.

Way to make a man jealous lol! Is your GTR painted athlete or sparkling silver?? Looks amazing!
