there sure are different stages for both turbines and housings, straight from Garrett, myAE86Turbo, you are the sucker! You givin' the turbo ae86 crew a bad name, so don't talk trash, do your homework.

You can take a look at the various pages to see that different stages have different dimensions, and possibly other differences in the turbines ie. number of blades, angle, deck amount etc.

a/r's and wheel trims are two totally different things

BLAAST

lol... That bithching is kind of amusing to me

Basically, the turbine STAGE is the size of the turbine wheel. It has nothing to do with the turbine a/r. Why do they call it the "stage" as opposed as the trim for the compressors It's simply because both the exducer and the major increase from stage 1 to 2 to 3 and therefore the turbine trim is similar despite the huge differences in flow.
For the compressors though, only the inducer varies for a given major (except the "Super" turbos that have an oversized major), making the trim a good way to size the comp wheels.

Here:

STAGE1 is 67 trim
STAGE2 is 69 trim
STAGE3 is 76 trim

a T3 stage 3 wheel is huge and will lag big time on a D16. Even with a 0.48 a/r turbine.
Heck, the stage 3 t3 wheel is larger than some T4 wheels!!!!
If it spools up at 4500RPM, I say it's a wrong turbo choice. PRoper spoolup should be around 3000 RPM IMO.

going to a t3 .80 exhaust housing is equal to going to a .48 stage 3 turbine/housing. A .63 would be like stage 2 over the .48

Edit: anyone who needs to refer to their BUMPER in stages, has a problem. I E Yo man i just got this sickazz stage 3 bumper yO... you should just quit life

BLAAST

WE are way off the D16 topic but just increasing the housing a/r on a small wheel will never be as efficient as a larger wheel. (assuming the wheel size is appropriate for your engine's acutal needs of course)

example: I'm at 23 psi on my H22. Stage 3. There's no way I could get as fast with a tiny stage 1 turbine, regadless of the a/r. However, while a stage 1 turbine would never develop as much power, it would certainly spool up quicker.
increasing the wheel or the turbine size! THere is the question? Don'T sweat... starting from a certain point, you'll need to increase both. and either way, it's the same give and take game for both: BIgger=slower spool up, more flow. don't make overkill choices, and you're a happy camper

accordepicenter

ive heard that clipping really doesnt help much at all, you need to go to a bigger housing or turbine to get more flow, clipping just makes you spool up later.

BLAAST

Yeah, clipping the blades make a faster spool up but you're actually clipping in the top end as well !
In some cases, a bit of clipping is not bad. but IMO it's never as good as selecting the appropriate specs to start with.

myAE86turbo

my bad ******, i usually have seen wheel trims labeled as ''P-trim" or "q-Trim" or "S-trim"...it's just ***** ****** abuse the 'STAGE' term around my neck of the woods, calling everything stage this-stage that...including turbos. i guess i learned something in this post...

damn i'm drunk.

but seriously, never really heard of wheel trims being referred to as Stage 1, 2, 3 etc.

neil85ae86 - i've been doing my homework since i was 8, for the past 12 years. sorry to have disappoined you. i have disappointed myself in the process. i have owned my 86 for 4 years and desired it since i was 12. i'm not a bandwagon drifter, for your information. matter of fact, ---- drifting. anyways.........for you....instead of boosting 11 psi daily, i'll turn the boost ****, and run 15 psi for the next week. consider that as 10 hail marys.

The main question is if this turbo is to big for the d block. Original post is almost the exact setup i plan on doing myself, i am trying to decide between t3 .60 or the t3 super 60 myself. From reading other threads and forums i have seen people spooling around 3.2-3.5 and reaching 10 psi around 4k or so using a t3 60/63 and 2.5" piping.

BLAAST

The basic t3 48/60 is sufficient for a stock D16.
The Super 60 will also work but power will kick in slightly later. It's useless in your case, unless you are shooting for 300HP.
