Series 1 has ceramic impellers = slightly slower spool up but can take higher boost.

Series 2 has plastic impellers = slightly faster spool up but cannot take as high boost.

Which is better?....How long is a piece of string? Decide what your objectives are, then work how you are going to get there.

:P why dont u get an aftermarket turbo? If you 'trashed' your series II, i assume its from running too high boost for it, so y not get something like an HKS GT2540 (what i got). it goes well, plenty of puff, garett guts (steel turbine, and ball bearings). stronger than ceramic or plastic...

uh, will dyno in two weeks when i get to perth. so not sure about output at moment. engine-wise i got: aforementioned turbo, hks blowoff, intercooler (aftermarket), 3.5" exhaust, apexi f'manage, forged pistons, metal head gasket (wont effect output), uh, thats about it i think. oh fuel pump. got other mods, but non engine stuff, like suspension, gtr wing (dont call me gay) wheels etc

yeah. sounds good. mine is internal wastegate, but biggest they make (i believe.) after that is the externals. friend of mine, who posts here, has one. hasnt fitted it yet. only thing i worried about is lag. i need a new computer to get most out of my current turbo. cuts in hard and late. like really hard. if i boot it in first or second, the turbo kicks in and the wheels spin. not chirp, spin. :P i getting camber adjusted next mechanic visit which should help. got 255's so cant fit anymore rubber under guards...

How much boost will the stock series 1 turbo take? Im running 12psi tuned with a haltech E6K ecu, FMIC, 3" exhaust ect..

What turbo would you guys recommend for standard internals and also what would you recommend for the rb25 with forgies ect ?

why don't u hi-flow your thrashed stock SII turbo rather than buying a new turbo with the same possibility of thrashing it again?

if u do NEED a new turbo, based on the info provided by surreal i would say SI as ceramic impellers and can take higher boost before sh1tting itself

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

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.
