Compression ratio 12.5:1. Bye-bye Super charger & Turbo build?
Hey, guys.
See Here: http://www.ft86club.com/forums/showthread.php?t=2131
Now we know the Compression ratio is 12.5:1
This is a nightmare for people who want do a turbo or a super charger build.
According to my knowledge, there are some ways that we could reduce the CR. I want discuss with you guys.
First, get a thinner gasket. This only can reduce a little CR, for example 0.2 or 0.3. Even we drop it to 12:1 its still not good.
Second, get after market pistons, rods. I think this is the best way to reduce CR, we may could reduce it from 12.5:1 to 11:1 or 10:1. But if we want crazy high boost... 
Last, engine build. A whole new block? If you got tons of $$$ then go for it.
Those are just my thoughts based on my own knowledge, I didn't do a lot of search, so correct me if I'm wrong.
BTW, intercooler, BOV, waste gate, piping, turbo will those destroy the balance of the car? I don't know, looking for answer.
