obviously the turbo is the same as a garret then since MTQ use a T28 rebuild kit for them.

They are not the same...its has already been documented...first of all...its years older than the standard t28s we get on the sr20s...secondly...just because a t28 rebuild kit can be used does not mean its a t28...

as has been stated runnign more boost through the rb25 turbo is fine because its not working as hard on the rb20. the clutch is an exedy heavy duty.

also does anyone actually have facts or proof of 15psi beign a problem? the only proof i have so far is that my mates has been runnign 15psi all day everyday for the last 60,000km putting out 180kw at the rears with less mods. No noises coming from the turbo at all and it was checked for play a month or so ago when the engine bay was stripped and wire tucked.

on another note whats a good size/ brand of injectors?

It has been well documented too that 15psi on a rb25 turbo is a bad idea...even on a rb20...it will still be shortening the life of the turbo...if it runs 15psi but only reaches max boost during the occasional squirt then it might be ok...but hold it on full boost for a few laps on a track and see what happens...

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)

      Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!

      Boost cut after swap(RB25DET NEO) R34

      Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.

      Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
