my car is at home in perth and im in qld on holidays at mates place and i want to make a plate to fit over the standard bov on the rb20det at home as all the gear is here to do it myself.

does any one have the dimentions from center of bolt to bolt?

and over all length and overall with. probably make it 6mm thick.

its to block it off so can install after market bov lower on the pipe.

AND WHAT IS THE DIAMETER OF THE HOLES TO FIT THE STOCK BOLTS?

Ok I am holding one BOV in my hand right now

A: centre to centre is 86 mm

B: overall length is 104 mm

C: width is 50 mm

D: Blow off hole diameter is 30 mm - the hole itself is 25 but it tapers out to 30 mm

E: Diameter of the bolt holes is exactly 10 mm

Hope that helps

champion, thanks mate.

thats a rb20det one right?

Also when you block off the BOV port you will also need to block off the hose connecting to it. Coke bottle lid is about as good as anything else

well im actually gonna use the plate to weld an elbo on ot to fit my BOV that needs a 38mm outer D.

easier welding the bov there than to exsisting intercooler piping i guess... like this below

until the coke lid melts, and yes they do.

how are you gonna melt it

the air doesn't get hot enough to melt ally, well, it shouldnt.

i suggested coke can too in his other thread :P

i ran for 2 yrs with a coke bottle lid in there and no sign of melting. Sure yours isnt making excessive heat ?

wasnt mine, but helping to change one out after going through nasho tells me they can.

id rather run a chair leg stopper onto the metal pipe if your gonna do it that way :D

hahah coke bottle lids are plastic Ash :P

Any way the original issue is busted!

brought a turbosmart adapter to fit the BOV from www.txeakit.net

interesting thread this one but... and yes, ill have a coke while fitting it. cheers guys

them dimensions are pretty spot on, heres one i knockd up quickly, not the best of quality... i didnt get around to rounding the corners off more.

coming april ill be making a run of blocking plates from billet with o-ring seals made to look factory. would be good to know if thers interest before i start em, shoot me a pm.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
