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.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
