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...

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

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 ?

came with the car. :P 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? :D

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

Waz.

    • Isn't there a fitting on the back of the balance tube? That's what the OEM boost gauge uses.
    • Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.
    • He's still joining you, he's just delayed it and won't have the fulleh sick ITBs...
    • The strange thing is this is a URAS front bumper (or clone of it). The bumper actually does not sit flush with the GTT hood - You need the addon to make the hood 'long' enough to reach the bumper. I have no idea why they didn't incorporate this piece into the bumper itself.. instead of sticking it to the hood instead.
    • Another thought on this OLD topic: When you paint your bonnet lip, leave a small unpainted back lip/line along the back of the lip, where it rests on the bumper. That way, the line in the back is much more prominent than the gaps in the front/under the lip - and it breaks the hood-to-bumper connection at the "correct" place, when comparing to a GTR. I'm gonna do this with mine this week, so stay tuned for pics!
