I did a quick search but found nothing..

so my question is.

when removing the head from a rb26 in a R32 gtr.

what is holding the head down on the intake side? i have removed turbos and everything on the hot side.

i'd say something under the plenum as i have not removed much from there other than fuel lines.

i've removed all the head studs, the 3 bolts in the corners of the head and the bolt on the ac pump. i can jiggle it a bit but it wont lift.

cheers

P.s. i've gotten bored waiting for the new motor to turn up so i decided to pull this one apart as much as i can to hopefully learn a few things!

i found a manual and i will dig into that tomorrow,

so it can be done without removing the plenum throttles etc??

just found a photo of new enging which looks pretty cleara, all these suckers come off??

it surely feels more solid than just hoses tho.

this is on an RB30ET but from memory dude there IS a bracket that is anodised gold that goes from the block the the runners, i guess all that alloy would need supporting, having said that your plenum it completely different, sorry disregard my waffling!

Behind the Acc valve air tank.

EDIT: I'll be removing the head of my 26 tonight or tomorrow, I'll take a few pics for ya.

mine will be off tonite :P

i'm onto removing that acc valve now or air chamber its called just under the plenum.

will see how this goes it shouldnt be too long before i got it out.

Done just as it started raining,

may have damaged the head gasket on the way out and i cut a hose or two as i had to act quick. damn rain. inbetween 6/5 on the headgasket looks a bit bent but this may have happened when getting the head off as i was jiggeling alot trying to find the last two hoses.

if you dont know, i had 0 compression in 6. all the rest were fine. 150ish across the park.

blowing alot of smoke/oil

inspecting under the head all the valves appear to be perfect, the top of the piston appears to be fine also. the bore also looks good in 6.

i will get some photos if the rain eases.

yer you seem to have had some det which will have a broken ring land when you get the piston out at a guess.

Have a look at the other pistons when you get them, take note of how the pistons look where the ring touches the ring land see if there is any marks that look like erosion.

    • Hi Apex and welcome! 
    • Probably too late to reply to this, but worth a try. It's not calliper flex, the calliper as a whole is moving so it has to be calliper mounting bracket flex.  Calliper mounting brackets are designed to stop the calliper rotating, they don't need to be designed heavy duty to stop the calliper moving in and out.  Whatever it is is not the major cause of poor pedal feel, the outer pistons are moving towards the disc rotor the same amount as the inner pistons are moving away from the disc rotor.  Hence no change in fluid usage, what extra fluid is needed to move the outer pistons is recovered from the inner pistons. For a calliper to move as a whole by far the most common reason is the rotor is not perfectly centred in the calliper.  The first thing I check is that hub face is perfectly clean, bare metal, where the rotor hats contacts it.  Then I check the that rotor is firmly held in place by at least 3 wheel nuts (or equivalent). If all of the above are confirmed to be in perfect alignment then I would check the piston sizes and ensure that the 3 inner pistons and 3 outer pistons have matching diameters (eg; 28/32/36mm).  I have seen a no name 4 spot calliper that had 1 of the 4 pistons a different diameter. Maybe I missed it, are both the callipers exhibiting the same problem? I would remove the transfer pipe and inspect it to make sure that there are no restrictions. Maybe you already have but if not I would return them with the video and have them confirm all of the above.   Hope that helps Cheers Gary    
    • If you have the original log book and it didn't have a chassis number quoted, then no money required.  I have "rechassied" a number of race cars, no problem as long as you have the original log book.   Cheers Gary
    • Well the good news is that it won't run any worse with an atmo bov than it does with no bov, I've owned a few Nissans over the years (r32, s15 and now r33), the stalling issue caused by a bov or no bov while still having an afm is easy enough to live with, most people get used to driving them and just feathering the throttle when you come to a stop to avoid it stalling. Changing to a proper ecu with a map sensor is ideal but in the short term I'd just slap in the bov if you really want the whoosh sound. I looked into the pass through type maf like the R35 one above but decided against it as the amount of oil and crap flowing through the hot side would mean you'd have to clean it often to keep it working.
