From Nissan Silvia

Hey all

Micheal and the boys at Turbotune here in Adelaide have recently finished playing with an RB20....

this is how it turned out!!!!

SPECS:

Std capacity R32 RB20det

Std original pistons

Std rods and crankshaft

New rings and bearings

Metal Head gasket

Std RB20det camshafts

Ebay adjustable cam pulleys

Std head

Shimmed Std Valve Springs for extra seat pressure

GTR inlet plenum dodgily welded onto rb20det inlet runners (none of the runners line up, it's awesome)

850cc injectors

Fuel pressure regulator

Ebay 100mm throttle body

Splitfire coilpacks

Ebay Stainless highmount manifold

Ebay External wastegate

Monza 600x300x76 fmic

T04Z turbo

Remapped Std ECU

370rwkw

Limited by cams, traction and stupid tall diff ratio. Hits dyno maxspeed, power still climbing

373rwkwRB20turbotune.jpg

crazy stuff... the dyno only has a 2 bar map sensor so they think the boost was going up to around 35psi!!

EDIT: Tuned by the one and only Jeff from The Speed Lab!!!!

EDIT::: as people dont understand!!!

I think you guys have taking this the wrong way lol

this car is not a customers car its not a car they drive on the road/track or anything it was made just for and only for the dyno!!!!

The motor was built after hours for a laugh just to see what they could make out of a standard RB20..

It didnt matter if it was laggy or cheap or if it blew up.... they didnt care...

It was made out of spare parts lol

Cheap and easy.... just to see what they could do with a standard motor and a remapped ECU!!!

It is turbotunes car that they made for the hell of it!!! And no... it wont last long..... its running 35psi lol....

I thought it was a bloody good job lol.... Its handled around 40 to 50 dyno runs over 320rwkw’s so far!!!

Dont mess with the strength of an RB20

Wow 500hp RB20! I didn't think the rods would live over 28psi.

I have a worthy RB20 to add to the list, but i would be cheating some, my donor chassis is a 2520lbs 240sx (2700 w/me in it) hehehehe, managed a 11.07 at 128.8mph, 1.521 '60 at low boost (22psi), and from experience, I'm well over 300kw at the rear wheels

the 11.07 run, 1.521 '60: http://videos.streetfire.net/video/19672bf...99e00b51eab.htm

an earlier run 11.48 at 114mph, 1.524 '60 : http://videos.streetfire.net/video/a8b026e...98e0175d428.htm

running slicks of course, 26 X 8.5 X R15

I'll be crancking the boost some this summer with a few more mods, looking to be in the deep 10's, how low i'm curious

Sylvain

well the season started over here in Canada, went for some tunning at the track to get things going and I pulled a 10.94 on the quarter with a 1.56 60', after some little tunning, it pulled a 1.46 60', clocked an eigth mile of 6.9 at 102.8mph but 2-300 feet before the quarter trap my intercooler piping blew off bringing the strong haul to a 11.15 at 102.0mph, next visit should be a solid 10 run.

the launch: http://videos.streetfire.net/video/240sx-R...0-at_162048.htm

I see some serious power from 20's in this topic lately!!!!, good stuff!!!! can't wait to get my shit together and get a dyno graph up in here. I'm surely not close to the last one, but eh, got to proove at least the 260rwkw, hehehe.

laters guys n gals

I know this isnt the For Sale section, but am putting it here as i would really, really, really, really love for someone with a car that is basically well setup with a turbo setup and good tune to buy the HKS 264/8.5mm cams i am now off loading.

Was going to try and get another good baseline before / after but i have lost interest in chasing setup of my car at present. But if anyone else has the motivation to play with their RB20 a bit more...mine is parked at present :)

my ears are burning :) perhaps a price?

Price is negotiable based on what they are going in :/ Engine is still running fine, car isnt :dry: Has a dent that needs repairing from an acco ages ago...needs some life put back in the suspension and brakes....just getting a tidy up whilst i am busy with work.

well i broke the 260rwkw mark but im not happy with it really comes on full boost at 5500rpm

im runnin a gt30 at the moment thinkin bout down sizing

what do you guys reckon the quickest setup would be? a big turbo or a small to medium size on the rb20??

  • 4 weeks later...

i've got the graph here - injectors are 100% on the pfc :/ so tweaked the FPR - i'll be upgrading injectors soon so will be good to see where its at.

It was wheel spinning on the dyno still aswell, while it was strapped and water in the boot.

still running the GT 3076r, 56 trim, with the .63 IW housing on standard manifold, standard inlet side - only mods to the head are tomei poncams and tomei cam gears (gears are both at 0 still). Boost is up to 25psi - realistically i think i'm reaching the peak of the turbo. but it's good to see some numbers. I'd like to see the max i can get with change of injectors.

Did u drive it ? How does it pull ? Where is your dyno graph?

    • 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
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • 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
