Hello i been thinking about switching my y5 to y8 and then boosting the y8, not sure though have some unanswered questions like, Can i keep my ac if i boost the Y8, because it gets crazy hot down here in the summer and i like to enjoy myself when i drive, also how much hp would i expect, i want to daily drive this thing and i want to keep its reliability to 100 %. Thanks sorry for once again another newb question.

 

just boost the y5, and buy an a/c compatible manifold

I had much fun with a boosted y5...I miss my Civic

 

The Y5 is actually better for boost than the Y8. VTEC has a lot of valve overlap so it just blows boost right out the exhaust. Not the worst thing in the world, but not exactly optimal. VTEC-E will help you spool up faster if it does anything at all, and the Y5 roller rockers certainly wont hurt.

Get yourself the Y8 tranny though. BIG IMPROVEMENT.

 

i have a y8 tranny already, so i should boost the y5, should i leave it on stock internals, the engine is kind off old

 

get it compression and leakdown tested to determine the condition of the motor. if that turns out good then go for it. i just boosted my y8 which has 144,000 miles on the clock.
