Guys,

I need to know the maxumum power i can get out of a Garrett T04Z 0.96 on a RB30/26 with cams, port polish and pump fuel

you need to add more details

for example is it a std rb30 bottom end, or Forged rods etc as i think the std rb30 bottom end will be your first weak link as the turbos got plenty in it. What cams, injectors and ecu and fuel pump?

i was advised by a workshop against using a rb30 bottom end with my t04z (1.00 a/r). They said that it would not have high enough rpm to take full advantage of the turbo. It will be fully balanced, argo rods/forgies, NEO head, tomei 260 cams, port and polish etc.

Your workshop has no idea then. :blush:

The rb30's rev fine with a set of aftermarket rods. The std rods are what cause the rb30 not to rev safely.

It may need slightly bigger than 260duration cams to make the most of it though. 265-272.

i was thinking bigger cams aswell although i can not find any cams bigger then the tomei 260..Strictly NEO heads of course. Apparently there are none that exsist so i am limited in that sense. The port and polish will be aggressive to compensate. What kind of rpm can the rb30 rev to with argo and balanced end? 8000k?

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
