DSM EF Turbos

From what I have heard they have only made like 3-4 ef1s so far. Ef3 would be nice to buy if they would build them for dsms. But you need a bigger exhaust housing.

You actually do not need a bigger exhaust housing. It cannot however be done to a EVO 3 housing due to the thinner stainless construction. An EF3 would consist of a upgraded turbine with I believe a 64mm exducer compressor wheel. It can fit into a stock 16G compressor housing with modification. I would recommend however using a downward facing compressor housing to eliminate the j-pipe.

I will be testing one of these on my car in a couple months. It will be nasty for a stock frame turbo.

An EF2 will consist of a upgraded turbine and the billet EF2 wheel that is used in the EF1 upgrade, this will equal 450+ and ridiculous boost response.

just a quick question to further clarify things, so would a core for an EF3 need to be from a big 16g? Would it be a 7cm or 8cm?


I wonder if a guy could use the BEP bolt on housings that are used on the Holsets.....hmmmm
