i know this subject has probably been beat to death but i can't really find the answer i am looking for. i jumped the gun early when picking my turbo size i bought the s369 but it ends up i decided to do a full built motor and the 369 will not give me the power i am looking for, luckily maryland performance will exchange the s369 i was thinking a s472 with 60% injectors my question is hp numbers should i see with that size and also if i would go bigger then the s472 what size can i go up to and still be able to drive on the street without it being a crappy ride.
