To be fair, the MTM has yet to be dyno'd and it also is a kit that is supposed to come "as is" without needing any tuning whatsoever. However, this is subject to a lot of debate.
Where MTM differs from other kits is the inclusion of their proprietary cat/downpipe which is a large diamter and has a highlflow cat.. which allows greater number in HP than an advertised E05.
You also have to take into account that while the E05 and sk04 are attractive alternatives to the K04, the K04 is a proven turbo and has been around for quite awhile in both stock and aftermarket guises.
If the E05 and SK04 prove to be as reliable and more powerful, by all means they are the better turbos.
Rich,
I have learned something about the E05 that I simply cannot revile because a lot suit is already in progress. But, I can tell you this, the E05 is a proven turbo and USED by VAG on stock cars!!! That is all I can tell you. But know this; the E05 is just as reliable as the K04. Too bad the same cannot be said of the SK04. As far as the MTM downpipe and cat, I stick with the test pipe from EuroCode. Makes more power then the MTM, costs A LOT less, and come smog time, it is easy to replace it with the stock cat. You know how I feel about MTM, it is just over priced TUV is great, but not the end all be all approval and it means nothing to CARB. So passing smog may not be as easy as people think with the MTM cat.
