Extra Steering Lock

My Car is off the road atm after the last time I went to Willowbank raceway which as I found out turned out to be a good thing as I might have found myself in a very dangerous situation driving anywhere.

I went to a drift night at Willowbank raceway and took my car out on the track for some fun. I did about 10 to 15 laps and noticed that everytime I went to full lock my steering would become very heavy. i didnt think anything bad of it at the time as i thought it was a HICAS issue. Inspecting the inside of my wheel i noticed there was a deep cut in the side wall of the tyre, a good 15-20cms long and it was several layers deep.

As Id spin out my steering was full lock and the added force of the car spinning and the wheels not being in the direction the car was travelling the tyre would rub up against the chassis and brake line mount and cut my tyre up

I have the same problem on the other side.

Now I went for a drive in my mates GTR and was diappointed at the steering turning circle on it, with my car doing a full "U" turn, in the GTR Id have to do a 3 point turn.

Now im just wondering if my steering rack has spacers inside it. Compared to other imports you can see there looks to be more lock.

Now what can I do? do I get different offset wheels, fit wheels spacers but being a street registered car will it comply with an engeering certificate, or would the rack be flogged out?

lower offset, i run rack spacers and every time i go back to stockies for whatever reason i get rail rub, simply because of the high offset. what rims are u running (width/dia/offset) and tyre size.

F 17x8.5 +38 offset with 215/45R17

R 17x7.5 +32 offset with 215/45R17

This is correct and suprised me as I thought I had 17x7.5 all round, but ive never had to change front tyres since I got the car.

Now correct me if im wrong, im still trying to understand offset, but the less the offset the more they stick out of the guards or from the hub?

Correct, Lower offset should push the outter edge out from the hub, I use this to work out what is what... http://marksink.com/tire_wheel_offset/offset.html

Putting your rear rims on the front and the fronts on the rear will give you 19mm more clearance on the inside.

yeh switch the front and rear around and u should be right, no guarentees as +32 is still fairly high, but should be enough.

and yeh, refer to this: http://www.skylinesaustralia.com/forums/Wh...de-t216654.html

regarding offset.

I switched the rims around. The rears look alot better with some of the tyre sticking out of the guard, if its goin to be an issue ill give it some camber.

As for the fronts it sits further away from the strut but it still looks like its goin to rub on the rail not as much as hitting the brake line bracket and tearing my tyre but still hitting that rail. Another thing is now the wheel sits more out there is more lock on the wheel and the tie rod now comes in contact with the lower suspension arm at full lock. When it does hits it, it moves that mounts for the caster rod, changing the suspension alignment. Is this goin to be an issue? I can post some pictures to make it easier to understand...

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
