Hi all. I am after response and a dyno sheet for the following turbos or some testamonial.

I have an RB20 and am going to go either the RB20 hiflow or the RB25 hiflow for the RB20.

on his site it says "1 bar from as little as 3000rpm" and flows enough for 200+ rwkw.

does anyone have some figures from a slide hiflow on an RB20. I have found heaps of info on them for RB25s but not the ole 20.

If I have searched and missed please point me in the right direction!

I am not trying to start a shitfight. just need teh info :)

what max power will the rb20 hiflow make and what max power will the rb25 hiflow make?

thankyou

1 bar at 3000rpm could only be done on an rb25 min... Plus it would have to have an EBC to get it there that quick...

I had a high flow GCG (which is a ball bearing one) on one of my rb20's and it hit 1.2bar at 4200rpm and thats with extensive mods.

I would extimate that a highflow on a stock rb20 would reach 1 bar at approx 4800rpm...

Hey guys

I did not even realise that i had writen 3000rpm in the items description.

I have seen them create 1 bar of boost on the rb20 highflow at 3600rpm with just a power fc, electronic boost controller,cam gears and the usual supporting modifications.

Sorry about the misleading information it has been changed now.

Obviously different cars will react differently depending on modifications.

The ratio of RB20 turbo's sold to Rb25's is a very large difference with around 1 being done to around 40 rb25-VG30 highflows as everyone generally just upgrades to the RB25 turbo and highflow that.

yep I thought it was a bit optamistic.

Slide do you have a dyno sheet of any of your turbos on an RB20?

Really I want about 210 at the wheels for my daily driver. Will the RB20hiflow be capable of this.

List of exact mods the car will have

GTR injectors

GTR fuelpump

Z32 AFM

Remapped ECU

batmbl split front dump

metalcat 3" hiflow cat

kakimoto 3" catback

Blitz FMIC

I will want to run about 16 psi

With the mods listed above I don't see why not.

I dont have a dyno sheet for either the RB20 highflow or the RB25 highflow on a RB20 as they are not a huge seller and i have just received feedback from customers and cars i have helped on the dyno.

The RB25 highflow will be able to get you 210 alot easier then the RB20 highflow which is why most go fot the 25.

A RB25 turbo elbow is required though as the RB20 elbow will not fit the 25 turbo.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
