Daveo,

I am really happy with it. I have my tune perfect now and its making quite a lot of power at 14 psi it makes 204rwkw and I can't run anymore than that till I get new coilpacks. I have just ordered splitfires and will get them over the next few days. then 18psi will see 230rwkw. Last time it was on the dyno it made 220 on 17psi but was missfiring all over the place.

In short I have not had a single problem, drivability is great and the acceleration when it comes on boost is nothing short of JEEBUS!!!

Had my final power figure confirmed about a week ago and have been a bit laxzy at posting the results. at 19psi the car is making 241rwkw boost comes on strong at 4100 and pulls like a train.

I have major traction issues so the car does not feel any faster than it did at 210rwkw. I have an open wheeling diff and fairly narrow tyres 215's once boost comes in hard it just spins all the way to third and 100kmph. with better traction via lsd and wider tyres it should be fairly fast in a strait line.

I am not really interested in 1/4 times but will take it to the track when I have the time. (no track in canberra) for daily driving there is a really nice fat power band and it pulls really hard. even better on the twisty stuff :P

It has taken quite a bit of effort to get the car to this stage and had been rewarding. the little R32 is a nice little package now :)

Thanks all :P I will have to get a printout from autotech. I will be in there next week and willl get one. was in a hurry to get afr's checked and left without the results :)

Hope you don't mind waiting a week for the dyno sheet.

Excellent results mate

241rwkw on a RB20 is outstanding.

The best all rounder is the turbocharger that you have and its the reason we are 3 weeks behind in orders :no:

:laugh:

Well guys, I picked up mine from Slide whilst on another quick visit to the Gold Coast last week.

I'm going to take some pics of both the high flow and stocky so that you can have exact comparisons to look at, but I'm looking forward to getting my L28 finished so I can put the turbo through it's paces.

Cheers, D

yeah i agree, 241 with the highflow is awesome on a rb20... even if you are using 100+ octane fuel :(

I got the RB25 Maximum overside highflow withstage 3 wheel for my rb20 and im sad to say its just too large for the RB20 :sick: Slide has come to the rescue tho and offered to make it a normal sized RB25 highflow so i can habve some hope of spooling it up , Big thanks to Slide!

so yeah i'll post results when i get it going again

When you say its too large where did you start seeing boost and where did it kick you in the back so to speak?

I'm trying to work out approx spool rates for the VG30 max oversize. Then I'll decide if its worth spending the extra 1k on a gt30 int gate. The time it takes to highflow the turbo will also determine if I go the slide or not.

If the cars going to be off the road for 3 weeks then I'll simply throw on a gt30 int gate. Unless Slide can sort out an exchange type setup, he sends I receive then I send my old one. :yes:

The 3lt will be able to spool anything slide can throw at it with a decent response time. I would ove to see one of these on an rb30.

What is your power goal cubes?

Power goal... 270rwkw minimum. The motors built for it, it has head work etc so all the little bits help. I plan to push 20-24psi if I run the gt30 or just 18-19 if I run the slide. But realistically I may end up having to wind the boost down a little with the gt30 as it may be a little too much for rwd.

The gt30r .82 will be all in by the low 3000's with good boost made by 2600.

I'd hope the slide would be in earlier which is why I wanted to know what you meant by too big. :yes:

Weighing up the options.

If the slide turbo is all in sub 3000's then 270rwkw + the slide will be a really good street setup.

If not I'll put up with the slight extra lag from the gt30 and be happier with a bit more top end power.

Its all an unknown.. :S

I just so happen to have a spare VG30 turbo :no:

It is not for sale only exchange for cases just like this :D

I do mention to everyone that lets me know that the max oversize is going onto a RB20 that the turbo is not designed for the 2Ltr and is much better suited to the RB25.

This is why in the highflow thread under "Highflows for RB20" only the "Straight RB25 Turbo Highflow" is offered.

The Straight RB25 Turbo Highflow is the best option for both RB20 and RB25

For power and response it is unbeatable for a bolt on replacement.

No problem at all mate :D

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By GTSBoy · Posted

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
