hi im trying to get a graph up... umm the tuner reckoned he couldnt stop it knocking at 18psi no matter wat he did... thats y its only 16, thats weired aye.. its alittle laggy

Well id be inclined to run a Bosch fuel pump, and run the std manifold. Pinging at 18psi seems a little strange...did he suggest the reson why it was pinging..

he said i should get some plugs a heat range colder...

are u talking about a standard exhaust manifold?

they just cheap weld n grind cams, standard cam gears..

a strange thing is the cas if nearly fully turned anti clockwise (Advanced?)

I would most definitely be checking the cam timing. Ensure it has been setup correctly and then drop a set of adj cam gears on it and see how u go.

How is the power curve when it wants to ping? Does it want to only ping at a certian rpm range? i.e in my case 4000rpm

I have had valve float issues where i bumped boost up and it would always want to ping at 4000rpm + the power curve would go flat from then onwards.

The last I highly doubt. But a few things to look at.

Hey RB power...what is your car like to drive on the streets?

tail happy?

Do you have any suspension/brake mods to match, 238rwkw is alot to stop with standard brakes :woot::blink:

just quickly....

whats everyone got their rev limiter set at??

since i got the highflow and having full boost at 4000rpm i hit the rev limiter alot!!!

i just dont feel power loss to change gear

street, 6800rpm

track 7500rpm

roy uses a nice rev limit

LOL...i keep mine at around 8,300rpm. I dont rev 3rd and 4th that hard, but i sure do rev 1st and 2nd gear out to make sure that when i grab the next cog i have as many revs on board as possible. The difference between 4,000rpm and 5,000rpm on my engine is proabably about 100rwkws so worth revving out the lower gears to fall into the meat of the power curve

If your turbo can flow the air, the std cams dotn seem to fall off too abruptly....mine still feels as though its pullign pretty well at 8,000rpm. i thnk it makes about 210rwkws at thoe revs?!?!?!

got the same problem as roy, need to keep the revs nice and high to bypass the lag. mines set at 7500 and is still climbing rather well. cams would definately help but might look at raising it another 300 or so.

i was revving to 8.5 on the old motor before she went.

proly will take the rebuild to a max of 8.3, but this time round with uprated oilpump and valve springs to suit.

gotta remember that rb20's are short oil drive motors so the posibility to destroy the oil pump is very good at high rpms/hp.

hey it seams to be ok alittle loose...lol....stock brakes and suspension apart from lowered springs and drift pinapples lol

my revs are set a 7000 rpm

what year was car? and how many km had it done before it let go?

also, were u driving it everyday at 8000+rpm?

      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

      By GTSBoy · Posted

      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.
