okay guys... there have been a few dances around the subject of this particular turbo....

I have had my car off the road for a little while getting a full rebuild with the following

Engine - RB20 ---> RB2.3

-forged pistons.... yadda yadda..... all new block...

-1.2mm tomei head gasket

-Tuneagent low mount s/s lowmount

-HKS split dump pipe

-Free low straight zorst

-Nismo 555cc injectors

-Z32AFM

-Tomei Poncam 256/256

-Tomei Camgears

-Nismo FPR

Now the turbo i currently have is an HKS 2510..... i want to go bigger down the road as the engine in built for it now.... but on the previous standard engine it used to make 181RWKW on a conservative tune at 1.bar.....

i have witnessed these make 200RWKW before at same or a little more boost.....

ive read that chris32 had made 208RWKW at his highest recording.....

in question if i rung my setup for all its worth i would be able to get 220rwkw on a 2510???

I really wanna see what this thing can do....

i think if that if that figure could be achived i would have a demonically fast street car......

thoughts please......

all comments welcome....

I think if you worry too much about chasing a number you could end up hurting your nice enw engine. Tubn eit up, run 1.3bar in it and it will make whatever power it makes. No doubt it will be quick, whatever the numer is

If you really need 220rwkws get the tuner to use a cup of coffee...or whatevcer it is they do to fudge figures :D

Too small IMO , a HKS 2510 is just a 2530 with with the more spool friendly - and restrictive - GT25/28 turbine . Aside from a few more recent HKS options ie GT-RS much of the HKS Garrett GT turbo range have been around a while .

One of the best all round in its turbine size range is the 2530 IMO . Your call but with what you've done to your RB20 to make it breathe the last thing it needs is a restrictive turbine to choke it up .

My vote goes to an RB specific 2530 .

Cheers A .

I agree with the above that this new engine deserves a bigger turbo.....and i will be leaning towards a GTRS when the time comes......

I just wanted to put to rest the myths that dance around this turbo.... i have always loved the power delivery of this one... and even with 180RWKW that it previously had.... it was so much fun.... max power is never the issue with me.... i just loved the mid range torque it produced.... and regardless of what others have said... it pulled all the way to redline.... never felt like it dropped off....

So...... i figure with all the mods done.... and having an engine that is supposed to be "more efficient" than the turbo... at least we will know what can be expected out of this little snail.....

I guess it boils down to how much power you want and how much you want to spend...personally i recon a 2535 would be awesome for a rb23...and be good to around 220-240rwkw with pretty decent response...

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
