Can you guys post some more info on these? I have seen a post or two around here about an EF2 and now an EF3 for DSM's? There isn't any info on your site and the thread on tuners seems to have pretty limited info.


Thanks

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 buying one for a DSM?

Right now only EF1 aka billet 16g is available for DSMers for $660 I believe. Customer must have a big or evo 3 16G for the upgrade.

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.

Hmmm, we need some more details, these are sounding interesting.

I'll talk with Bob tomorrow and get better info for everyone. I know from experience that the EF1 makes power. Aaron is rocking one as well. So much fun!

No I'm not buying one, just curious is all and I'm sure more people would like to know about them.

So,

EF1 = billet EF2 wheel, bigger than a "stock" Evo 3 16G turbine wheel
EF2 = upgraded turbine wheel, same compressor wheel as EF1
EF3 = upgraded turbine wheel (bigger than EF2) and an even bigger compressor wheel (next size bigger than EF2)

sound correct? SO would the EF3 be the next biggest size compressor wheel then? (EF3 compressor wheel?)
