hey guys,

been a while since i have posted but i think i have a real crappy problem...

ok..

i havnt drivin my car in weeks which is an r33... and this morning i thought i would start her up and let her run for a bit...then take her for a wash and a little spin.. i let her warm up checkin all the fluids first and so forth.. everythin was just as i left her... and as i backed her out of the garage i heard a weird rumbling sound coming from the high mount manifold... so i jumped under the bonnet and gave the car a rev.. and man was my car loud!!!!.. so i checked all connection for anything suspcious until i came across the devil!!..lol... i noticed that there is a hole (about half the size of ya pinky fingernail) in the manifold... its just under where the turbo sits on the manifold along the pipe that goes to the external gate.. WHAT DO I DO???

is there anyway to fix this with the manifold still in..or does my whole setup have to come out!!.... this is the third time this yr ill have to bring out the turbo!!... so sick of it.. anyway anyhelp would be greatly appreciated.. from where to fix it to a shop where i can buy manifolds.. btw from the s/e suburbs if that helps..

You might be able to have it welded, totally depends.

You will need to see someone who can weld DECENTLY and see what they say.

Poor man pays twice, cheap china manifold is now almost worth what a decent one outright is :(

only problem with probably 90% of stainless manifolds available atm is they are all crap...wall thickness too thin, design is piss poor. If you modify them and brace everything they will last a while, on a road car that is. But the time, money and effort that goes into pulling it off every 6 months because the flanges have warped and cracks have formed and need welding makes it worthwhile to actually spend more and buy a descent one that you wont have to touch after its been fitted the first time. On the race car i got sick of pulling it off and repairing it and putting it back on every 2nd race meet.....discovered 6boost manifolds and have never had an issue......ever.

Nothing wrong with stainless.

My old Nismo stainless manifold is almost 20 years old (now with a friend) and its never cracked once :O

All about the quality of the stainless, thickness and design.

most stainless manifolds and every stainless manifold ive seen on the market are made from 306 and 316 grade stainless and this is a very poor grade to be making manifolds from

trust would have to be one of the worst when it comes to big brands, ive seen so many of there manifolds crack

X2, stainless isnt a problem, infact i've noticed recently alot of race cars (i've ben lookin at US ones) have been using them, but obviously thicker/of a higher grade

full race use CAST STAINLESS for there manifolds which are alot stronger compared to most of the junk stainless manifolds out there

personally i would still go for the steam pipe option

LIFE TIME WARRANTy :)

by "bracing" the pipes - are they little bits of sorta U shaped metal welded on right at the ends of the flange? just wondering, i just picked up a new manifold with these things on it - i guess by no means is that a garuntee of quality - worth a try though.

yeah the U shaped bracing is standard on most stainless manifolds

nah ones i saw were hand made from pipe and steam-pipe-esque bends

although yes i too would opt for actual steam pipe

Yeah we had a stainless SR highmount gate flange break off...right in the middle of the pipe, and on top of that while it was broken off, the turbo still spooled up to a bar! (previous boost control issues)

The material was rubbish. So was the design. Was bought from a reputable retailer too.

Bought one from Just Jap, havent tested it as yet. Its twice the weight too, should work good.

      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).
