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

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
