ok i was gonna use these on my 12 valve but my 2004.5 has alot of lag. i have everything to run triples an from my thread in the 2nd gen area im gettin that the 3 turbos are normally closer in size, that being said will the 2 s359 s work better with the stock turbo on my common rail? its got a edge juice with attitude an the egts can run up near 1500 sometimes an theres a good amount of lag. so give me your thoughts will this work on my common rail better than my 12 valve???

 

Definitely would work better on the CR. The maps should be pretty similar between the s359's and the he351. It should give you close to a 2:1 pressure ratio.

What size are the turbine housings on the 359's?

Also, you must port the wastegate on the he351 to run trips. Heck, it should be done anyway as a single.
