The EFR 6258 is the smallest and fastest spooling EFR turbocharger in the lineup. Ideal for small engines in single OR twin turbo configuration, this is an excellent turbocharger for autocross, rally, drift, road racing and street driven applications. The 62mm OD compressor has a 49.6mm inducer rated at 44lb/min max flow - supporting up to 440hp. This compressor wheel is versatile with very large map width for outstanding power potential, even at high boost. The low inertia 58mm Gamma-Ti turbine wheel is optimally matched for maximum response and fast spool with the FMW compressor wheel. EFR 6258 uses the smallest-sized EFR compressor housing, making fitment in the tightest engine bays possible. Ideal for use in single turbo applications for the 260-440hp range, or as twin turbo applications 400-700+hp **will not shuffle in twin turbo configuration like twin garretts** Ceramic Ball Bearing only, watercooling recommended.

Pictures of said turbo, with "Kelu" and the "date" next to each photo. Low post count, out of country, higher price item... Just for forum members saftey!
Plus how it is new in the box, when last May you posted about the setup of yours???

G: look on the DIC, it shows boost ramp versus rpm, known as "lag", a turbo capable of 440hp boosting 160 kPa (23psi) at 3000rpm on stock LNF should ring some bells if you are knowledgeable.
TurboTechRacing:
1) the turbo is in New Jersey even I'm from Europe, I shipped it to a friend but meantime I went with a different turbo so I have no use of this anymore. This brand new, but I had this exact model in my LNF Kappa back in April 2011 and this one which is for sale was delivered in August 2011
2) The turbo is in an unopened box, I will post pictures with it if you are interested but I considered irrelevant pictures with a box
3) Lowest price including ebay for this turbo is $1460-$1550 and generally delivery of such a model means 1-3 months waiting for delivery, how you saying is higher or are you selling this for less?
4) I might not be an high poster here because I own an Kappa and I usually visit Kappa forums, I even visited US to a Kappa Meeting if you want to find more about me you can find in Kappa community
Here are pictures:



EVERYTHING CLEAR NOW?

I think what he meant by "higher price" is that it isn't a cheap item like spark plugs or something. Not saying you are overpriced..its just a high dollar item.
Thanks for explanation Fross but his words: higher price item sounded diferently in my ears, maybe because I'm not a native english speaker.
terry11: How much power you aim? 
cranemaster: i have bolded this to the engine using a casted Garret manifold (build for lsj), wastegate and BPV integrated in the turbo, modified the downpipe to fit a VBand. On the intake side I have use silicone couples to connect with the existing pipes. A tune and ready to go, the mechanical modifications were done in 1,5 days.
Dart_SI: I have bought a casted Garret manifold for $500 which fits the LNF and looks like a perfect match for reliability and lag

And to the OP, for what the car or the bike?
I wouldn't run this size turbo on my cobalt I like the efficiency range of the 7670 at 20-23 psi over this one. Plus I'm used to a big turbo
