well i was just wondering when you guys add a turbo kit did you guys have to switch anything else like your fuel injectors or your pistons because i know the s2000 has a pretty high compression (11:1) and i know turbo tends to work better with a lower compression ratio. so what im wondering is if you had to replace you piston when you got your turbo kit? or did it just work in it fine with out switching anything out. thanks im trying to get a much info on modding a s2000

 

Your stock engine will be fine if you run low boost. It's wise to change the injectors and use a different engine management.

Problems arise when you do not tune right and/or boost high for more HP. Don't go more than 7 or 8 psi.

 

I used 650cc injectors with an AEM.
