there has been some discussion previous to this...do a search for posts by aspec or a-spec

basically you can run two garret gt28s through their custom manifold and plumbing....i have the m2 twins and one of the concerns with the current sets of available twin upgrades is that they use the stock manifold and thus suffer from restrictive flow eventually. Aspec has built a new manifold to handle more flow.

to give you an example...the garret gt30 internals that i run are rated to 400 and 450 hp EACH...however no one will ever get that out of them because of they sit on the stock manifold.

if i had the cash...and was to do it again...Id go with aspecs set...that is..IF i could run them sequentially.

I think the aspec set is non seq only though...so Im not depressed that I didnt wait another year...at least not yet. I havent seen the numbers...perhaps aspec will enlighten us all.

I think that kit comes with twin GT2835's, but I'm not sure. It is basically just two smaller single turbos. Paired together, they'll pretty much be like having one bigger single, only with a little better spool up rate from having lighter compressor and turbine wheels. SP Engineering did a kit like this but I think it was with bigger turbos. www.spengineering.com You might be able to search around for more information on it, but the smart guys will probably start hitting this thread before too long.
