R33 turbo

[JET-33]

what kind of turbo is the one in an r33 gtst

and what are the internals like..eg ceramic wheel? ball bearing?

and has any1 got a hi-flowed one? if so, how much boost can it run now and how much better (hp) is it...

cheers

The turbo is a Garrett T28, It has a ceramic wheel, non ball bearing, I wouldnt push boost past 12psi on everyday driving, but it can handle 15psi with cold air temps outside, but only every so often, not advisable to run 15psi hard consistently

Hope I helped u out mate

[JET-33]

yeh 14 is what i thought...just wandering how much after hi-flow

i wouldnt run mine past 12...

i had no idea it was a t28, i didnt think they had the same turbo as a 200...and i heard somewhere that they r ballbearing..must have been wrong ey

[Guest <NIS_02>]

as u can see I got 225HP @ 14 psi of boost, that about 40HP increase over standard, which runs around 10psi at 5000rpm, with a more free flowing exhaust expect another 20HP easily at the treads

[Guest <NIS_02>]

Yeah same turbo as 200sx, BUT... 200sx has steel wheel, which means it can handle more boost You can replace the ceramic wheel with a steel wheel, and could run maybe 20psi, but then more adjustments of other components will be needed

[JET-33]

jibbed, they get a steel compressor wheel and we get ceramic

[JET-33]

check ya pm...did u reset ya ecu the way meggala says on his website

[Guest <NIS_02>]

Yeah its screwed hey, we got ripped off with the ceramic shit heap!!!!!!!

Are you sure those figures are right. My r33 got 232 rwhp @ 6500 with just a cat back, pod and remapped ecu & 10psi.

I heard the R33 had a T25 or something and the 200 had a T28 ball-bearing turbo. I don't know though, that's just what I heard. Also, the Series 1 R33 apparently has a ceramic wheel and the Series 2 apparently has a plastic wheel.

[JET-33]

yeh ive heard that about the wheel, the turbo also, i thought it was a garret t25 ballbearing.....hmmmm

any1 know exactly what 4 sure?

[rev210]

It's not a garret T28.Does not have any garret parts and it does not have a T28 flange.

It's a hitachi, with a T3 flange. T3's will fit as will t3/4 hybrids.

It is ballbearing, it has a ceramic wheel, it will break if boosted too much (14psi +)

[JET-33]

thats what i was thinkin...except for the t3 stuff...wot does that mean...u can bolt a t3 straight on? t3/4 hybrids (that just a hiflowed t3...t3/t4 internals yeh?...

which bit is the flange?

[Jay95R33]

I think the R33 turbo's are T3 flange with T28 internals or something wierd like that.

Yepp, a T3/T4 will bolt onto the factory T3 flange inlet manifold, but I think you need to make up a new dump pipe.

And as stated before, boosting above 12-14psi may have you looking in your cat converter for part of your turbo !!

[JET-33]

yeh i know sthe stuff about boostin, but thanx 4 ya help, im just tryin to find out shite about the actual turbo...

thanx 4 ya help again..some good stuff there, a lot of valuable/interesting/varying information

[JET-33]

no one ever told me about the 73/4 boltin on..mite have to check it out

cheers jay...

Depends on which 200SX model your talking about. The S14 came with a ceramic wheel T28 while the S15 came with a steel wheel.

my gtst had a ihi turbo, ceramic with steel bearings, couldnt run much boost withit it, about 9psi. t28

took it of and took it 2 garret and they turned it into a t3/t4, now i run about 10/11psi and the car screams, i need to put a cooler on if i want 2 run more boost,

also it feels like the car doesnt strain as much as it did b4

[silverskyline]

there ihi turbos, which r made with hitachi components, not much u can do except to get the turbo converted to a garrett, and then u can get it hiflowed

[JET-33]

i think il just leave it, depending on what a hiflow is worth..just wait and get a good t4, maybe hiflow that after
