lol, yeah he's a nutcase

Let me know when - ill come and have a go aswel :(

Nice work Steveo good to hear its back on the road, I hope to have mine done by Xmas.

Should I bring a broom for Wakefield this weekend or will you be able to contain yourself?

Ive got some spare bits left over if you're after any strange bits

Can you bring one please? Dont forget your apron this time :D

i blocked off one of the restrictors only, theres a few rb30's without them that run fine.

Have to wait and see what it will be like with constant high revs

I wouldn't sweat it mate. plenty of high power RB26s running fine without an external oil drain. as long as things are done properly. block off a feed, and get the internal oil returns ported out a bit and cleaned up so they flow more. much easier and seems to work very well. that's what I've done with my donkey. I might still add an external return to be safe, but if you do ad one, try and put it in the right spot. just replacing the rear welsh plug like so many do is not the way to go.

yeh i've also been told since im not running a rb25de i dont have to worry about the extra feed to the head

get my new exhaust mani next week, you should of seem the extent of the cracking in my so called "trust" manifold.

OH

MY

GOD!

hahaha very happy for ya mate, i'll have to make a trip to Syd again, I wanna see your beast on the road!

I wouldn't be planning that trip any time soon..... :)

So whats the damage Steveo, anything major?

Dont know yet, its sitting in a garage all dirty - ive got to clean it tonight (or tomorrow) and call the mechanic a bit later today to see about the next step. Id prefer to pull it apart where it is now cause anything out of place......well.......will look clearly out of place, but that may affect the warranty so im not touching it (and neither is anyone else) until i know what will affect the warranty and what wont

OH

MY

GOD!

lol, you missed it - but thanks heaps spanna :)

its a replica of what i had on, just made from 4mm steam pipe instead and as i've been told the collector is bigger etc etc

Sick

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
