Sump Is Hitting Sway Bar

Hi all,

Before the standard "Use the search function" response will be used - I have searched and there is very little regarding this issue using a OEM routed swaybar.

This topic is regarding installing an RB30DET into a R32 GTST.

Currently, my sump (High Energy style) is clashing with my sway bar. My engine mounts have been modified as per the PDF (potentially slightly lower engine position) but this has led to the sump hitting the Whiteline sway bar (SK group buy spec).

My question is what have people done to get around this issue?

On initial glance, my solution would be to space the sway bar down at the chassis mounts. Use a longer bolt and washer. The only issue I can see is that the link pins/drop links will no longer be long enough. However, this is easily overcome by either modifying the standard links or purchasing aftermarket ones.

The only practical downside I can see from that is the sway bar may end up lower than the cross member which in the vent of bottoming the car out, the sway bar will scrape/bend. So long as the link pins are actuating the sway bar perpendicular to the lever arm on the sway bar, kinematically I see no change.

Any other ideas/options?

All input appreciated.

Cheers,

David

Whiteline sell an S-link kit for the sway bar which would give you some adjustment i believe.

Thing is, I dont think the amount you will need to space it will alter much at all. A 10mm drop would do SFA to the spherical ball joints on the links.

Just how far out is it do you think?

Well realistically speaking, the engine mounts have been modified as per the RB30DET PDF, so in saying that it should be clashing at a MAXIMUM of about 10-15mm.

Car is at my engine builders as he is installing it, so dont have the car on hand to measure/take pictures.

Just wondering if there are any other ideas other than the above mentioned fixes?

Heat up the sump and modify it with a hammer (does it have gates and baffles inside? Modify them first).

This has got to be the dumbest idea I have ever heard...

Mate this is not a personal attack, and I generally respect your posts as a whole... But this is WRONG.

DO NOT play games with the motors life blood, RB's are plaigued with oil problems as it is. Why create another?

Your criticism is welcome! I actually meant it quite literally at the time - easy fix to modify tin sump to accommodate a few mm but I guess it needed a little more thought...

I had the same problem in my cefiro.

It just slightly touches.

those whiteline S/ 8 looking links are rubbish, imho.

My car is street/ drift and like all of my cars, usually set up with soft susp and big sway bars.

I thought I'd try a heavier setup with no front swaybar for a change,

If its rubbish, custom swaybar is the go.

I tried spacing the stocker down, but wasnt happy with the results I got.

If it was a stock sump I would just notch / ive the sump a small releif.

Yeh...problem is that I dont want to have to get another sway-bar since I have already paid for this upgraded one. Sure I could sell it, but its just another hassle I don't want to have to deal with.

I think spacing the sway bar down will be the way to go. If necessary I will get those whiteline S Links. My standard links need replacing anyway.

If I still have problems, guess the way forward will be to modify the sump, or get a new swaybar...neither of which I will like doing.

Finally dropped the 30 back in the car last night and with the engine mounts bolted with stock holes there is about 10mm clearance between the swaybar and ASR sump, will throw a couple of shitty pics up later.

      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.

      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.
