na man only looking at 1 bar or 250 to 280 is rwkw.

i appreciate what you are saying about the gt30 but it will be maxed out before i reach my goal. of 400rwkw.

So do you want 280rwkw or 400rwkw? Theres a big difference when it comes to setup....

it has a 0.5 to4 front housing and 1.06 rear but i'm gonna change a few things soon to a .7 and .86 rear. John the ultimate goal will be around 400, as my weak points at the moment are the box and clutch which is going to cost around 8k so i'll save that up and get ppg gear set and nismo twin plate. so atm i'm just building it to be able to do what i want too, when i'm going to do it.....if that makes sense.

I take it you are using the factory boost pickup point - ie the nipple at the start of the scroll? If so that point has a higher boost level than manifold pressure. The pressure difference between the two increases logarithmically with airflow rate.

If you change to manifold pressure as a boost source for the actuator you will generate a lot more boost.

^^^^^^doesn't make sense as this is a 3ltr, it also has bigger cams so i'm expecting it's go to drive like a strong na off boost, and beside i've seen gt3540rs on sr20 with plenty of mid range, the turbo was actually designed for 2.5 to 4 ltr engines so being a 3 i'm kinda right in the middle, and if a rb25 will push a gt30 to 300rwkw and have plenty of mid range i can't see why a gt35 on a over sized forged rb30 would do any less justice. the engine is being built to handle a flogging.

You do realise bigger cams are actually going to make it weaker off boost yes?

It's not a high comp N/A motor you are dealing with here.

so in turn it would also read "true" if i where ton read it from the manifold and not the turbo side of things which would allow me to adjust it accodingly for what pressure i want???

You can use either boost source. The reason ford use that pickup point is to allow better control at higher rpm. And by better control I mean better ability to lower boost.

right so nismoid i would be better running the factory cams ie rb20 ones as i was only going to use stage one tomei items. Also what is the safest power level and rpm of a standard balancer as i cant find the info.

Not enough for you. I am running a max of 6500 to protect my stock bottom end and N1 pump but if you want to rev high you should get a better balancer.

      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).
