Lol @ 2071 and 2650.
Even Stevie Wonder could see what you did there. OP...don't turbo anything...EVER. Just buy an Acura RSX type S and drive it to school. |

Are you referring to the 56.5mm T25 3071R turbine, or the 60mm T3 3071R turbine?
(please buy an EFR so someday I can forget all I know about Garretts) the 2871 turbine is 54mm. and they only list a t3 housing for the 3071 or a v-band. what am I missing here? |

The EFR's 58mm turbine is one of the secrets behind the huge power numbers it can produce. It makes up for the loss in spool that normally accompanies that extra size by using trick materials to keep the weight and response time down. |
you gotta go "off the menu"

When I went from ebay 3076 to EFR 7670 (same size compressor, but vastly larger turbine on EFR) the spool stayed the same, but power went up about 20%. Flows wayyy more than the smaller turbine.
your engine is probably happier with a larger turbine too... less backpressure in the turbo manifold. |

also probably has something to do with going from an ebay turbo to an authentic turbo. was the ebay 3076 ball bearing? I haven't looked at ebay turbos in so long I wouldn't be surprised if they have the ability to offer BB now....
your engine is probably happier with a larger turbine too... less backpressure in the turbo manifold. The engine does like the larger turbine. Interestingly I tried .63 and .82 A/R turbine housings on the ebay 3076, the .82 was a touch faster up top, but spooled a lot worse and overall the car felt slower. Car went faster at the drag strip with the smaller A/R turbine housing. |
