Q: Compression ratio? - 2005 N20
Hey everyone out there I've got a question for you all about a 2005 Saleen N2O with a 2.0 Duratec. I would like to put a turbo on my car but I want to leave the nitrous system on with the turbo this is like the only major upgrade I want to do on the engine besides like injectors or such. My question is about compression ratio I don't know what the compression ratio is on the stock engine nor do I know what it is with the nitrous. Basically I want to make sure that on my stock block, and head I would be able to run a turbo with the nitrous to spool it. I mean I just don't want to install this and find out I need to change my whole block or head. I also saw another Saleen Focus owner without the nitrous that turbo'd his car and he had to add something to the exhaust because supposedly the Magnaflow exhaust can only handle like 8 pounds of boost and obviously a turbo is gonna need to push out more boost then that, at least for me it will. So, if anyone out there has any answers to my questions or knows where I can get said answers I'd greatly appreciate it.

the stock rods and pistons wont stand up to more then 250 whp safely. can you go past it im sure, people have.. ive been talking to a tuner that deals with tuning foci... just using the n20 maxs out the motor....... once you do the rod and pistons your good for over 400+hp

So basically I would need to replace the rods and pistons in the engine and add the turbo that's it for the engine. I also heard that I need to do something with the exhaust due to the fact it would only handle up to like 8 pounds of boost. Is there any truth to that?

You can run up to 12 psi on the stock engine with the fswerks turbo kit. Also with the saleen exhaust you are ok to run it you just will be restricting the power. I have an 04 saleen focus that i turboed last summer and i felt the difference on how it pulled going to a bigger exhaust. With the fswerks turbo kit the recommend using a 2.5'' when you put the kit on but you dont have to.
