Hi Guys,

Just found out ive got a cracked cyclinder head, and im trying to figure out what to do.

Im not too bad with doing basic mods.. but i have no idea when it comes to complexities of the engine/internals itself.

Do I:

Repair/fix existing crack?

Engine swap for another RB25

While its out go forged or RB30DET?

meh its out.. get a cheap Nissan v8 engine.

or other..

as i said.. i have NO real idea what to do at this point, i havent been quoted YET for fixing/repairing the existing head.

My goals for the car at the moment are very open.. i WAS aiming for epic responsive RB with 250-260rwkw.. however if im going to buy a new engine, why not do work on the engine for 3-4 months and aim for a higher power output since the engine is out/alot easier to mod.

atm i aim to finish the engine with 10k to spend TOTAL.. dont add in costs of selling existing block/turbo.

part of the 10k will go towards Exhaust+clutch+fuel pump+ecu+ebc.. so take that outta the total.. wanting reliability if its not too much to ask for also..

Car already has an Apexi turbo to make the 250/260kw..just hasnt been boosted yet

Thx for any/all HELPFUL input.

10k doesnt go far, especially when ur handy rather than totally competent. Not having a stab just being honest.

put another head on it and get back to doing good valuable bolt ons with ur 10k :P

I had my head ported out while been decked with tomei cams, guides, seals, seats.

valve guide in #6 overexpanded, cracked the head, ruined.

the machinist shop and my tuner/workshop re-did another head for me no charge

car had coolant.. but you see if you remove sparkplug #6 and look in there and crank the engine, you will see coolant going in there.

so yeh.. coolant leak is for sure.

Just gave my mecchy the go ahead to take the head off and tell me whats broken.. and ill update thread from there.

    • 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.  
    • 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       
    • 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).
