Meh, its a garrett and its small. And for that money you'd be better off spending a couple hundred more and getting a BW EFR series that will spool just as fast and be able to make twice the power.

Ive got a brand new garrett for sale that would do anything you need for 1/3 of the cost....
what would you suggest then leafy? I'm aiming for the 400 hp range and my engine is already built.

Well, how fast do you want to spool? Spool time close to that garrett would be something like a BW S256 with the 76 AR housing, which should be like half the price of that garrett you listed and should actually do better on the mid range power based on the compressor map. Or for a few hundred more either the BW EFR 6758, 7064 or 7670. You could even maybe get away with the 6258, but you'd have to push it really hard and I think you'd need a ported head and a semi decent cam to get to 400 wheel, of course it would pretty much create boost like a blower. I'm not the best at sizing turbo's though And the EFR sizing kind of confuses me a bit, the smaller ones you can choose between a .64 AR with a t25 flange (thats a tiny ass flange to try and cram 400 hp worth of air through) or a .92AR with a twin scroll t4 flange. Which seems to me like it might be on the big size. To me it would seem like a twin scroll t3 flange with like a .75ish AR would be excellent on these ERF turbo's for our cars. Someone who's sized more turbo's would know a bit better.

basically id like to spool by 2500 rpms as i want it to be a street car, not a track car. my head is ported on the exhaust side and polished and im running secret cams. I would like to use a t3 flange also.

thats got to be one of the worst parings of hot side and cold side ever. a tiny t25 hot side paired with a 35r compressor? it may spool somewhat quick but ur gonna run out of steam real quick with cause that hot side isnot gonna be able to match the flow of the cold side.

for the record, the link doesnt show the options i was going to use. i was gonna use a t3 flange, not the t25.

i always thought a gt3076 was a little big for the ld9 but i guess i was wrong?

A gt35 is a perfect match for an ld9!
I would DD an LD9 with a gt3076, I have one on my cobalt and LOVE it!

a t3 flange is just a t3 flange, if its not a t3 hot side its not going to do anything, even if it were a t3 hot side u would still have a t25 wheel in there to choke up ur hotside..... and then if it were a t3 hot side and wheel u would have a 35r on ur hands which is a 700 hp turbo and big. just keep it simple, do a 50 trim with a .82 hot side that will get u what u want.

Yep, like I said in my PMs, tubular turbo manifold makes a helluva difference. My GT3076R is at 21 psi at 2500 RPM lol.

A little big? LOL. I've proven that idea to be quite false a couple years ago, & I was just using a lil dinky ebay loggie log log.

Can't say I've ever heard of an S252. Same compressor exducer of 80mm, just a 52mm inducer i assume? Same turbine of 61.5mm Exd. And 69.5mm Ind.?

I believe the s252et is a bullseye turbo that uses the 70mm BW s200sx compressor wheel, opposed to the 80mm s200 wheel. I'm sure they would give the choice of either the 61mm or 65mm exhaust wheel.
For what it's worth, the vanilla BW s251et is part #177257. They used to be less than $600 brand new at one time. I bought my s360 earlier in the year for less than $700 from

This might help
I have no signiture
You're right about it being a bullseye turbo, a quick google search showed a couple sites selling them for $1,100. I don't know why, but, bullseyepower.com never seems to be updated, listing all available turbos that they make which would explain why i've never heard of the S252.
I have a super strange compressor wheel on my S250, 50mm(1.95") inducer and 73mm(2.87") exducer. i haven't found anyone that sells that wheel combination yet, the closest is
AGP turbo but they don't list the major compressor diameter so it very well could just be the standard 70mm. Which means my turbo could flow anywhere from 44-48lb/min. Do you happen to know the calculations for figuring out maximum compressor flow rates?
Is the 73mm measured at the base or at the extended tip? That might be where the discrepancy lies.
Regarding your question about the max flow rate, that depends entirely on the aero of the compressor. In general, a 50mm wheel should be in the ballpark of 45 lb/min. I've looked for a compressor map for my s250et for a long time, but could never find one. For the s200sx, the BW catalog only shows the 56mm wheel map, which is completely worthless to either of us.

I measured the wheels 2 years ago and can't really remember exactly where I measured from so I'll take a vernier to it tomorrow with photos so you can tell me if I took the measurements from the wrong portion of the wheel.
ion, what did they charge you to make that manifold? and did you have to take the car to them or is this something i can have made by calling them?
