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

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
