Well i was searching around this excellent forum to check out some stuff and some interesting things came up. For one the issue of the R33 factory ecu being a pain when you do mods because it makes the car run really rich and bad also that adding a fmic creates lag. I have a standard series 2 R33 and i want to do 3 mods but unsure now because of these issues. The mods im planning to do are

- turbo back exhaust with split dump

-panel filter

- FMIC ( im going to buy the one that attaches to factory pipes so no cutting into chassis or fan blades)

The thing is would the ecu crap itself if i did these mods or i would i be better off safety wise getting a safc and tuned by a pro, i would go the power fc but im not interested in boosting at all as i want to increase power by a bit and have the cool racer look with the fmic, thats where the issue of the FMIC comes in, do fmic's increase lag?? im going to have a full turbo back so i will have a minor increase in boost so yeh will it affect drivability?? What are your thoughts as I want to discuss these things with you skyline savvy people before i go and do anything. thanks for your replies in advance.

with these mods you will be fine with the factory ecu, just don't wind the boost above 10psi, or you'll go rich and retard and loose about 30rwkw of power.

with these mods, At 10psi, you'll get about 140rwkw

youll find it hard to increase power with adding some more boost. adding some more boost (to a certain extent) increase airflow. airlfow makes power, if you run 12psi with an safc it should make some good power, if you run powerfc with 12psi it should make a little more power and drive awesome.

Hey mate, I'm looking to do the same thing to my stocky s2 r33... I've got a k&n panel filter in (I really don't care for pods), and i'm now looking for a split dump and 3" exhaust.

I've heard that a split dump pipe is only really effective if it is of a reasonable length. i.e if it is a dump and down pipe in one. (all the way to the cat)

As for the cooler, they do exist, if you're wondering. I can't remember the brand, but there is a FMIC that will use your stock plumbing/holes to get the air to and from it. I was considering using the R34GTT cooler, as they are a little thicker, will bolt right up in the same spot, and flow more air and are supposed to be good for a max of 220kw?

I think I won't bother with spending mega bucks and running a bunch of wires through my car by buying a PowerFC. Possibly an air/fuel controller will keep the ratio's correct... giving more power for the mods without over-richening (yes it's a word... from now on) the engine.

Let me know how you go man, i'm really keen to see what mods make what power, and i'm looking to dyno my car soon, and then once each time I do a significant mod to it.

Cheers!

Randy, the powerfc is a plug n play ecu, takes ya about 10 mins to install and like 10 mins for it to set itself up while idleing, and then your good to go. I think you can get them for like 1000-1100 with controller del, which is a good price. imo thats not mega bucks and its not running a bunch of wires through my car.

Infact, correct me if im wrong, but there would be more time spent in setting up an air/fuel ratio controller then there would be with a powerfc?

Not being rude mate, but what youve said just doesnt seem practical to me at all, or youve got your wires mixed up.

IF people did a search they would know what they are indeed talking about :P

and yeah, a PowerFC takes about the same time to install than an SAF-c, takes fark all time. Depends how moticated you are :D

yeah, I know what they are, and what they cost... I thought you had to get a proper tuner go over it after you install it?

Ah well... it's big dollars to me... =-] (bought the car for 16K)

      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).
