how do you actually measure a turbo??
everyone talks about H trims and all tht stuff...but im new to turbos and dont know how to measure one to know thats what i bought?
i trust the guy i bought it from but i still want to know how to figure this out....
like a T04 and all that stuff.....
i got a Airesearch stage 2 that has a TO4B intake AR.60 with a Htrim wheel...
now i may be crazy for buying stuff i dont know what it is but id like to find out how to measure it...

ok, so now i want to take of the compressor wheel...
is it just the bolts on the back??
is it ok to take just that off without it needed to be rebalanced??

Okay, do you want to take off the compressor housing to access the compressor wheel?
Or do you want to remove the compressor wheel off the shaft?
If it's the former, yes, just remove the 6(?) bolts on the back of the compressor housing.
You might need to gently tap the housing to get it off the backing plate.
Be very careful removing the housing, as the tight tolerances make for a very close fit - it you cant the housing far enough to contact the compressor wheel, you can damage the compressor wheel itself.

If you're gentle, you should be okay.
Don't be banging on it too hard!
Soft taps with a piece of wood (or wooden mallet or equivalent) should be all you need to loosen the compressor housing.

ok, got it off..... this is what the housing looks like on the inside of it...

is this normal shaft play wear or is this pretty bad???
and can i dot he same thing for the hotside as far as taking it off??
i know its hard to see with it being blurry but its all i got for a cam.

Take a pic of the compressor wheel?
If there is contact, it's easier to tell on the compressor wheel.
The compressor wheel blades should have "clean edges" - if they are jagged, then that is bad.
The dark spots are normal, as you're still running the stock emissions system?
Either that or your air filter isn't doing that good of a job?

i checked them and they are shape as hell but no nicks or anyhting like that...
the other picture has some rough pathces where its dark in the photo...and next to it its smooth to a polish..lol
and the hotside comes off the same way??
im not sure what emissions where ran since i have not used it yet and just bought it
There's some funny spot on the top fins of the bottom pic, but I think that's glare from the pic?
If the fins are all clean with nice edges, it looks fine!
Yeah, the turbine housing pops off in a similar manner.
The bolts are a little harder to get off, but don't worry about breaking them.
The turbine housing is usually stuck pretty good, but use the two alternating bolts that hit the oil flanges to "push" the turbine housing off the center housing.
Good luck!
BTW, did you get to measure the compressor wheel?

You really need the dial caliper accuracy to get a good measurement.
Notice the chart is down to hundreths of an inch!

Yep, if those measurements are accurate, you got ripped off.
I used to run a T5/T6 compressor side.
It's good for about 250 to 260 at the wheels at around 15psi.
It makes about 20 to 30 more hp over the stock compressor wheel.
Sorry about the bad news.
It's definitely NOT an H-trim.
