3 things. if ur looking to make 400whp out of your sr its gunna get pretty pricey...one of my friends has put 8gs into their sr's and are only making 350 with a disco potato if im not mistaken...its either small turbo+med boost+built sr=reliable or go big turbo and go boom...another friend of mine is putting 10g's out on his motor build complete with full race dual ball bearing turbo kit (i think its a 42r) and is looking to make somewhere near 500.
you might wanna think going rb25 with a nice gt35r on low boost...thatll get you near 400 off the bat and you wont even be close to maxing out your turbo...a little lag but extremely fun in a 240
now if youre looking for an h23..i can possibly make a phone call to a buddy of mine who gets them in pretty often..im pretty sure hes got one now
