I just got the car tuned today at Hi Tech Dyno.

Boost was put up from 9psi to 12psi and made a little over 180rwkw.

I have a cat back exhaust, the rest stock. Also the electronic boost controller is not stable.

I think i have marked the correct boost settings. Bottom one is on low which spikes then goes back down.

My next plan is to replace the stock front pipe and replace the stock air box with air pod intakes plus a better boost controller.

well airbox & pipes will be fine

There is another reason your not making power, cat perhaps or inexperienced workshop? could be dyno settings even but realistically you should be 200-220rwkw

Im running GT-SS admittedly, but i'm making 250rwkw @ 12psi - stock GTR dumps (not R34)

Before that i made 250rwkw on 1bar with the stock ECU & compliance cat...

Plenty of people running 240-250rwkw @ 1bar on the stock ECU/turbos etc, so you shouldn't be too far behind

Have i marked the correct lines for the boost? low and high?

What gains should i get with an upgraded front pipe and better cat than compliance cat and pods and boost controller?

looks like uve marked the right lines... but noticed the speed???

was it done in 3rd gear??? surely that cant be 4th gear...

i think the dyno operators messed up ur run

Have you run a car up in 3rd and 4th? It really makes no difference to power at the end of the day.

please stop looking @ ebay

For $150 - i CANNOT be good regardless of rating

y not???? aslong as it all lines up, just use plenty of exhaust cement to make sure it doesnt leak,,,after all its just a tube of steel... worst case scenario you loose $150 on a dodgey product, maby even get a refund if you threten to leave bad feed back.... in the end you could end up saving hundreds on a brand named equivalent...............

and a gtr on 12psi should be running way above 180kw,,,, my gtst with just an exhaust got 160rwkw... with the standard actuator i can only boost it to 10psi and i recon i get atleast 180kw (feels like it anyway)...

maby your engine has had a hard life or the dyno guys did a dodgey job

From what I know, Hi Tech is run by John Keen who used to (think he still does) race professionally and has worked on many race cars over the years... Always see race spec porches in his workshop and some pretty mad imports.

So as far as the workshop goes they have a pretty solid reputation. Give them a call and ask to talk to John Keen himself, pretty sure he'd be able to sort it out and give you plenty of feedback. He doesn't beat around the bush and is very straight forward with anything mechanical.

But beware, his work isn't always the cheapest. But guess that's the price you pay for quality mechanics.

he has a nice dyno setup and certainly knows how to strap the car on for max traction,

but seems to struggle with ebc setups

10 minutes dyno time = $200 WTF?

and this was on several occasions

never again.

hmm 180 Awkw's doesnt sound that bad or is that 180 rwkw??

my R33 gtr was only making 210awkw @17 psi with a new greddy boost controller, pfc, dumps cat back, air intake,cp pistons

so 180kw doesnt sound that bad for only 12 psi, unless there is something wrong with my car too.

^ your results are the sour ones mate :)

210 @ 17psi... thats nasty bad.

1. Stock turbos shouldnt be pushed that far anyhow

2. If you only made 210 with aftermarket ones, id be even more worried about something not being right

what should i get just by adding a power fc?

powerfc SHOULD jump it by about 20-30 rwkw

I bought mine comletly stock and added a catback exhaust. Got it dynoed and it got 189 rwkw.

Eventually added front pipes, powerfc and cam gears and dynoed at 250rwkw @ 13psi. (on a not too aggressive tune too )

I gotta add, my car did come fitted with a high flow cat.

      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.

      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).
