Hey guys,

I just bought myself a freshly built rb30 for a steal up here in Canada. I have a few questions about it however

The motor still has M11 head studs but I think I will need to switch to M12 to be safe. the block is o-ringed with a custom copper gasket so I'm not sure how much head sealing is going to be an issue. Is the upgrade to M12 needed or just recommended?

I'm also looking for 4wd adapter and I can't figure out which one to use. The oil pickup is going to be a pain because I have a trust extended sump. If it's easier I might just switch to a 4wd adapter and new sump from the same manufacturer. That way it will bolt up no problem. What is the best route to go here? I'm planning on running 700-800whp and the car is mostly a track car but I don't think I need a block brace, Is this correct?

I'm running a OS Giken twin plate clutch right now but I'm not sure if it will deal with the torque of an RB30 so I might have to upgrade. Anybody have any experience with the OSG twin on a high power RB30?

I'm not sure if the shop that built the motor has much experience with RB30's. They have built a lot of motors but I'm wondering what kind of mods are needed for circuit work. Opening up oil returns, etc, etc. If a pro RB30 builder is willing to advise on this build I would gladly offer up some money in return and of course not divulge there tips. I know this is unlikely but a guys gotta try.

Here is the mods on the car at the moment (I might be leaving out some)

BNR32

Koyo rad w/ twin electric fans

HKS oil cooler

Tomei cam gears

ATI damper

270/270 10.8 procams

Extensively ported head (Quench pads retained)

Cosworth valve springs

xs engineering throttle seals

HKS bar and plate intercooler

Custom t4 twin scroll manifold with single 60mm tial WG

GT4088r

4" stainless exhaust

Vipec V44

Greddy rail w/ 800cc injectors

x2 bosch 044 with large surge tank and Tomei lift pump

HFS-6 water/meth injection kit with direct port x6

HKS Boost controller EVC 6

HKS SSQV II

OS Giken twin plate clutch

OS giken 1-5 gears

ACPT Carbon driveshaft

4.375 diffs

ATS Carbon 1.5 way front diff

Factory rear diff reshimmed

That is all I can think of right now but I'm sure I'm missing a few things.

Thanks in advance for the advice.

Rob from Rips

http://www.ripsltd.com/

is very generous with his advice although it would be only fair to buy the sump and adaptor from him!

Alternatively you could source them from Dick at

http://www.hytechengines.co.nz/

or there are a couple of Aussie suppliers I believe.

So I think I'm going to use the Hi octane platinum 4wd adapter/block brace and Hi octane race oil pan.

I'm going to keep the M11 studs but was wondering if there is any stronger options than just the regular ARP studs?

I'm also going to get a new clutch seeing as I'm pretty sure my OS giken twin won't last long. I'm probably just going to wait until a good used triple plate appears in the classifieds.

My GT4088r is also being replaced this winter by a new EFR8374.

I can't wait to drive this thing in the spring.

regular M11 bolts can handle 600hp, so 'normal' arp studs will be fine, unless youre aiming for 40psi, then there are L19 ARP studs,

but i really think thats overkill.

id be looking at the RIPS gear personally, not to say that there is anything wrong with youre choice

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
