Bit generic question... starting = 1psi?

Also depends on mods too, a full exhaust will spool up a turbo quicker than a standard exhaust... more boost = earlier boost too...

If the car is dead standard or say just a cat-back id say that would be fairly close to right... maybe a few psi before 3,500rpm in 2nd but nothing too noticeable if its standard

I'm think about getting a turbo back zorst. Is there a lot of gain by doing the dumps? or should i just spend the money towards a PFC?

I'm choosing between a PFC & microtech. Ive been told to go with microtech because it is more flexible as you do more mods but i'm not chasing huge power, just lots of response as this is more a street car. I've read on this forum that PFC is really good for what i want to do (zorst, boost up, PFC & tune). Which way should i go? any one had any experiences with both setups? What kind of power would this set up give me?

Also, is there any point in going a brand name zorst like blitz? To me, a pipe is a pipe & don't really care about minor power differences. I think the money you save can be spent on other mods which will give more bang for the buck, like a PFC.

Lastly, where can i buy the $22 boost contoller from? is 14psi really pushing the stockies?

Sorry about the long post :(

There is alot of hp to gain from doing a turbo-back exhaust system and Id look at that before you consider management! If your still not happy then throw on a boost controller for 1bar with a front mounted intercooler kit. Still not happy then go the power fc and tune, and maybe an rb25 turbo charger as its slightly bigger!

Does a 32GTR has a FMIC and it should be fine for the power i'm chasing. Also, bolt a rb25 turbo? just 1 of them? i was thinking something like 34 N1s or 2530s. but new turbos are a long way off atm. Can't justify the price.

The straight line performance is already getting dull but when i take the puppy around corners, even stock power is a lot to handle.

Thanks for pointing that out! I swear it didnt say GTR in the title before... lol

Yes i was refering to a GTST, GTR with a full exhaust and boost up with give you plenty of fun times :(

Is it worth it getting a brand name zorst? they are quite expensive & imo just a pipe like any other pipe. I've been quoted a full stainless zorst from turbo back (no dumps) for $900 for a workshop. Does this sound right? Also, what factors determine a good quality zorst?

I personally dont think its worth going a brand name exhaust, if hes said turbo back without dumps... well its not turbo(s) back then lol

Have a look on the forums for gtr exhaut bits, get yourself some dumps, front pipes, cat and a nice large (3.5') cat-back exhaust!

How much difference do dumps make? i'm thinking of not doing it as the turbos have to come off.

Will bring your spooling time right down with some good hi-flowing dumps...

If your changing the turbo's fairly soon then maybe you should do the dumps when you so them, but your exhaust is only as good as its least flowing part!

I was thinking of changing from the front pipes & leave the dumps on until new turbos are on. Will there be much improvement with this set up? or should i do the dumps now as well

Id say fronts + cat + cat-back exhaust would be a 40-50rwhp difference? So your going to notice a shit load more power outta the rb26! Personally, those twin HKS style dumps are goin fairly cheap on the forum... id probably just grab some while your doing the rest

      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).
