Yeah, these otomoto turbos are known for being very laggy for the power they produce, wouldnt recommend a VG30 turbo, just an rb25 one and get it highflowed if you wan t anymore, keep the smaller exhaust housing to move the powerband down in the rev range, still make up to about 250rwkw with a highflow

SLIDE RB25 highflow for RB20 would be the best option, price wise as well.

People have made awesome power, and there not THAT laggy..

Check out "Rb20 Turbo Upgrade, All Dyno Results" thread if your thinking about upgrading your turbo, some proven results in there.

Thanks,

i know someone who is putting 1 of these (pretty sure it was this one and not the 480) onto his rb20. he has it all on but is yet to get it tuned. will let you know how it goes. should be better than the t70 that was on there. that didn't boost till 6000rpm.

For the money i would go a highflow as well.

There is a bit of modification that you have to do to make the KKR fit.

At the end of the day its like everything else and you get what you pay for.

The KKR kits are cheap and there are people making good power with them but they do rely on there warranty to sell the product from what i can gather. For less stress i go a 20/25 highflow from Slide and do it right the first time :thumbsup:

Laggy, the same as an rb25 turbo, but bigger exhaust housing and different compressor wheel(i believe)more tuned to low boost, so when you put it on an rb20 its laggy and inefficient, heaqps better to go with an rb25 turbo, and get it highflowed if needed

Ive got a 430 on my rb20.

Had to modify the water lines, oil lines bolted up, also had to grind some of the comp cover (it touched the exhaust manifold)

i'm running gtr injectors, microtech lt12s, walbro pump, cooler, straight through exhaust, stock internal motor, no cam gears.

made 210rwkw with 19psi

i've got full boost just at 4000rpm in second, slightly earlier in higher gears.

Ive been running this power for 9 months and not had a problem. The car see's drift track too, so its thrashed fair good :laugh:

my 2c worth

Due to personal health issue's i am no longer making the highflows sorry guys.

Hopefully soon when things are sorted out i can go back to them but for now just trying to get better :(

Sorry to hear mate.

Your health is more important and hopefully you recover soon and get well..

Good luck, and take care.

Hope to see those high flows in the future :)

Thanks,

Abu

hey mate,

i just put a moc kkr430 on my r32 rb20det and they have WAY to much lag, if you gonna bomb shit outta your motor then ok, but for minor upgrades i would say go a T04E, thats what i'm getting now for mine.

but it is fun when you finally hit 4000rpm and full boost...lol

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • 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...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
