After many months my giken rb 30 is ready to go into the 'hole' trouble is that due to this engine being taller that stock the inlet manifold/surge tank does not clear the clutch master cylinder !

does anybody have pics of keir wilsons 'set up' or have a contact for him, or has anyone got a good solution to this problem ????????????????

thanks

John.

i have the same problem dicky with my rb30 in my GTR as well.

What i have done is ditched the booster, got a slave cylinder off a r32 gts-t, and also the pedal box, this is important as the gtr pedal box uses the studs coming off the booster but with the new set up its reverse the studs come off the gts-t pedal box... Next what you need to do is take apart the pedal box and swap pedal arms, ie. you need the gtr pedal arm in the gtst pedal assembly.. Next there is a metal stopper on the gtr pedal arm that stop it coming foword too far, you need to grind that off and recess a little notch so it can come foword alot further.

Next the thread rod that is your adjustment needs to be cut down to nearly wear the thead ends then more thread has to be tappep down the rod, this is so it doesnt hit the back of the pedal arm and you still have adjustment..

Next you need to elongate the pin hole that holds the slave cylinder on to the pedal arm by about half a hole, again to avoid the back of pedle arm fouling on the threaded rod. The slave cylinder on the engine side also needs to be spaced foward 5mm, you can do it with washers but i made an aluminium plate so its a bit more solid and wont pivot. I then air hacksawed a little semi circle in the lip that hangs out of the firewall and you can get to the resevoir nicely with out needing a custon resevoir.

Thats basically it, if you wanna ask any questions please do, its a pain of a job took me around 3-4 hours.

PS lube up the rubber bush when you take the pedal arm out to stop future skweeks.

We don't need to do it that way.. just watch :)

You do need to drill 2 holes for the master cylinder however as the holes are in the opposite position.

We have a nice remote resevoir, so no cutting or grinding anything.. and making the rod to the correct length is simple, done it a lot.

Relax.

    • ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
    • And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.
    • No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
    • Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender
    • I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
