G'day,

I just bought a vl with an rb20det in it, the bloke i bought it off put a hi-flowed rb25 turbo on it. I was just wondering if someone could tell me the differences between these two turbos? Is there any size difference? Also, i want to get an aftermarket computer for it, what is the best computer for this motor? Are there any avaliable that plug straight in?

Any help is greatly appreciated.

Thanks, Pat.

hi patrick

you can do a search on the word hi-flow or "highflow" to learn about them and the changes they make to them to get more flow out of them.

the main differnces between the rb20 and rb25 hiflow would be larger housing and compressor wheels (and housing) and new bearings/core.

the unit would flow more air and give more power etc etc. a lot of guys use the std rb25 turbo on the rb20, so using a hiflowed rb25 turbo on the rb20 is even better

there are quiet a few ECU options for the rb20 but not many plug and play options, the main true plug and play unit is the apexi powerfc

it will be around $1800 for you with a hand controller as the unit isnt made anymore. its a direct plug and play , first key start unit however and lots of tuners can tune it

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

      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!

      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...
