is it a good idea? or not because of the already high compression.

 

You are not going to get much more of a response then the one i am posting right now. This has been covered more times then i can count. Do a search and you will find a wealth of information!

Edit: ..... you should ultimately read one key important idea and that is that TUNING....TUNING....YES TUNING is key!

Edit again: try http://www.boosted-hybrid.com .... there is more information on that website then you could ever ask for!

 

Not if you don't know what you're doing..the search button is your friend.

 

High compression isn't really a problem unless the tuner sucks. High compression just means theres less room for error in the tunning process. Don;t even think about going turbo with out some sort of stand along fuel managament. An fmu or afc will not cut it. It will short term but not long term.
