i was thinking about putting a evo 3 big 16g on my ecotec. i was really not looking for anything over 10 psi right now. now the moter is stock. i was just going to put some arp head studs on, and run with that. what i want to know is if anyone has done this and how everything worked out as far as what rpm it spools at (lag time)? also any problems to look out for? any input would be great. thanks

it would spool up quicker on a 2.2 ecotec then it does on a 4g63 (dsm) ....

i have the super16g on the ecotec and it spool very quick. good tourqe through all power band ranges.


Hahn Stage II
350 H.P. to the ground coming very soon
with total build up.
