DSM EF Turbos

**goodhart** · 12-13-2011

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.

I would love to try one out too.

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!

**goodhart** · 12-13-2011

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?)

I'm shooting from the hip, like I said I'll get more info today.

We plan to offer EF1/EF2/EF3 upgrades to the best of my knowledge, however, we haven't been able to source cores to offer these as new units as of yet. As Nick outlined the EF1 is a compressor wheel upgrade only (larger than a 16g though Aaron), the EF2 is the same compressor wheel with a turbine wheel upgrade, and the EF3 includes even larger compressor and turbine wheels. The EF2 is a 450+whp turbo for Evo platforms, but I wouldn't be so quick to say that it would perform at that same level with DSM housings (although the EF1 has been performing very well).

Awesome. Thanks for the info guys.

thanks for the PM Nick

It's easier to explain it that way, I don't care to answer a million questions about a 69mm compressor wheel vs. 68mm.

Of course you could put out some information that would be the end all of EF-line turbos that could be copied and pasted everywhere.....

I'd be shocked if a 5 spd DSM with EF2 didn't break 450.
I'm excited to see this DSM EF3, plans to go bigger?

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
