Has anyone (hoping an experienced tuner will give advice) actually looked at the compression charts etc. and figured out which turbo upgrade would be the most EFFICIENT for our evos?? i was planning on throwin on my downpipe etc... but decided im not even going to waste my money on all that and juts save a little more and go with a turbo upgrade since i will have to have another downpipe made anyways....im lookin at the hks gt 2835 or the 3037.. i kno the 2835 is more streetable/less lag... but i wonder which is more efficient? shiv... AMS....etc? hopin yall reply... also... if our stock internals hold up to 450 whp... what parts would i have to build to safely run around 500 whp...

 

i dunno , id like to know myself...id be interested in the 3037s info at the same time maybe a 20G/ or garrett hybrid(20G housing)

what is the 3037 cfm vs the 20g's? BIG price differance
