Thanks for that. Like I said, I asked and was apparently given the compressor A/R instead of the turbine. I couldn't make out info from the pictures but that's what I was told.

On it!

lol vendor
he's trying to swoop it up on CL or some jank forum member who doesn't even know what a/r means.
my only question is: you were saying you wanted to do things right. why are you looking at jank setups again just to save a few bucks? isn't the definition of insanity doing the same thing over and over and expecting different outcomes? or something to that effect

OP...before you go buying stuff with specs that you don't understand, figure this out.
What is "A/R" and what does it mean?
Let's say you have a 2560 turbo with a .64 housing, then you have the exact same turbo with a .86 housing.
Which one will spool faster? Why? How does this number impact these effects?
Seriously, figure the answer to those questions out, and you will feel much better about what you're looking to purchase.

For the OP, The 2871 and 3071 are almost identical turbos. The "28" is referring to the T2 exhaust flange, and the "30" is for a T3 flange style. I believe the 2871 uses the same exact compressor wheel but the turbine is cut down a little smaller to fit into the T2 exhaust housing. The difference in spool between the turbos assuming .64 a/r for the 2871R and .63a/r for the 3071R will be within 300-400rpm...the 2871 will outspool the 3071. The 3071 can make more power once you hit the 350whp threshold.

i may have been looking at the wrong turbo, rofl. (for some reason I thought the 2871 had a different trim size wheel) still differences in turbines make a big difference -- not even the difference in overall size/trim, the 2871 has 9 blades where the 2071 wheel has 10 blades.
there are plently of turbines that share the same compress wheels, but i wouldn't call the "almost identical"
like a 2860 and 2650.
(buy an EFR)
