which is better a turbo ??

[gaffa]

Guys i have a Series II skyline have recently trashed my Series II turbo now i want to know what is better a Series I turbo or a Series II turbo and why

[DREMEN]

me too

There much the same I beleive, both T28 ball bearing units.

You should perhaps look for something bigger like a T/04 turbo and maybe run 16psi/18psi max boost. :burnout:

[surreal]

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.

[T0nyGTSt]

Both turbos have a limited lifespan to put it bluntly...

Also both have ceramic exhaust wheels but the intake impellers differ as above?

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...

[KamikazeR33]

how much power u puttin out yoda and what mods u got done?

[Guest Yoda]

kaze

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

[KamikazeR33]

nah gtr wing is da bomb, as long as its genuine

im lookin at a turbo upgrade myself

and im lookin at what path to take and what to buy and stuff

[Guest Yoda]

its genuine. adjustable too .

i'd definitely recommend a steel turbo. spin faster. stronger. speak to the guys at www.c-red.com.au

they'll help you. tell em Johann sent u

[KamikazeR33]

yeah ive talked to few places bout 400hp and 600hp bolt ons for r33 gtst

[Guest Yoda]

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. i getting camber adjusted next mechanic visit which should help. got 255's so cant fit anymore rubber under guards...

[Guest Yoda]

tonygtst, is your specs right?

PowerFC + AVC-R + ARC FMIC + Kakimoto + 2.0 bar turbo = 43.5rwkW

??

[Lepperfish]

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 ?

[KamikazeR33]

how much did ur 2540 set u back?

also whats it rated at (hp)

i remember its a straight bolt on also isnt it?

[Guest Yoda]

came with the car. think its 480 hp rated? i'll have to check again. jeff/lumpy at c-red could tell u better. its pretty much a bolt on. i have custom dump pipe made, and got high flow cat, and a/m catback, but u should already have the exhaust by the sound of it. wanna buy my turbo, and i'll upgrade?

[Guest Yoda]

sorry, that should be 480KW. ie, bit over 600 HP...

[gaffa]

All i wanted to know in all of your experience what should i do SI or SII turbo not looking for big kW numbers just want to put another turbo on it and drive it

[JimX]

Series 1 would be better, but check the condition before you buy. ie, I'd rather a good condition S2 than a worn out S1.

[WazR32GTSt]

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
