The only boost control device you need is your right foot :P

THIS.

I can't understand why people have those two stage boost controllers. i.e. 12psi low boost, 20psi high boost.

Pointless, if you want less boost, lift your foot a little??

My factory boost controller has been modified to give up to 13-14 psi, I have a switch turning it on and off. Boost gauge doesn't like regular changes though.

Clutch slippage, low boost till fixed. (done)

Coilpacks going, low boost till fixed. (done)

L plater girlfriend driving, low boost.

Car feels different, still nice to drive just a bit slower, I actually preferred it for a while.

Traction on nankangs is poor, esp in the wet, low boost helps as the stock turbo is insanely responsive and quickly goes from 7-14psi, wheelspin. Also with stock turbo there really isn't much difference between 7 and 14psi in terms of right foot position, just in power. The boost curve is weird because I don't have an electronic boost controller. 7 psi by 3000rpm, 14psi by 3100rpm.

Not sure why you'd do it with an actual boost controller. I did it to help the turbo, and the above reasons.

It's not going slower I was after, it was less boost, less engine stress. I preferred the switch.

It will have grip Steve. the tyres on it atm are just some nankangs that we use for the dyno

Track spec is going to be something entirely different.

I have to give credit to Marty White for the job he did on the head. It looks like bugger all but as he said, watch it spool. And boy! does it spool.

I had nankangs on mine for the tune and they turned to smoke and sprayed rubber up the wall and onto the roof of the car. lol

It looks like I'll get to the 5's just as you're getting to the 4's. Have you decided on turbo?

If you get into the 5s it will be on a boost level you wouldnt use everyday.

As for the turbo, it has become a very hard decision now. There are sooo many i want to try. There is one combo i would like but it means a total re-engineering of the exhaust side of the engine and im chomping at the bit as it is to get the thing on the road.

Lol, I'm not one of those high boost low boost switching people. Set it once then leave it, I figure it's not like the car runs at the highest boost all the time, only full throttle and that's up to my right foot to control :D

The 5557 sounds like it could be the winner for you from what powertune have done so far. I know what you mean about trying heaps of setups-that's all I talk about with Tonys brother every weekend......now where did I leave that money tree....

Steve, the 5557 i think is GT3076 territory.

One of the options was a Precision turbo though.

Believe it or not i am already planning the next engine turbo combo and the current one is not even finished yet :D

Likewise, as you know.

nice result noel you crusty old man. although it really is way too much power just to drive to bingo on sundays but I guess you can get there early for prime seating. :D

hehe. seriously though that's a kick ass looking set-up mate. hope it gives solid service for years to come. :P

only reason i like having diffrent boost setings is so when i go to the track i can put my car on 16psi instead of thrashing it on 19psi all day long.

It didnt :D turbo number 4 shat its self on saturday

Yeah we are removing it now to send it off to Garrett to find out why. The last 3 turbos all failed for legitimate reasons. I'm expecting this one to be the same. It's a damn shame but we'll see what they say. Considering he's got sonic stickers all over the car I hope they give him a free one. If not then I'm sure he'll move to turbonetics or something journal based. He certainly doesn't need to worry about response

      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.

      Strange issue RB25DET wont start

      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.
