I'll be getting my type R in the next 6 months or so and it will be my daily driver. There have been a few related posts. I also asked a similar question in the general topics but got completely hijacked (apparently a lot of you disagree with turbo'ing these cars).

Considering a pretty tight budget, and the fact that I only want to put out about 5PSI, will I be able to add a turbo without modifying any of the internals? I'd like to stay away from that because the standard compression and internal work is perfect. I'm impressed and I'd like to leave what honda made. IE turbo + intercooler. I'd be willing to upgrade the injectors and pump if necessary but I DONT want to mess with compression at all. If I was to go down that road I might as well just start with a crappier integra model.

Considering this, how much performance will this put out in the end?

 

I think Erik Bs setup is perfect for you, he's running 5PSI and making 254whp at the wheel, yet the turbo is capable of pushing close to 30PSI, so once you upgrade your internals in the far future, you can keep the same hardware, just turn up the boost and fuel.

 

Sounds perfect. I checked out his kutsuju link. Looks perfect for what I want to do.
