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

I'm hoping to have a stock rb25det/5557 plain bearing result veeery soon.

400 would be nice.... ha ha ha at the fly.

400......hp :D

Likewise, as you know.

I've got the bug bigtime to drive it again

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

    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
