Too Many KM's?

I was thinking about going for a Turbo D set up, but is 230 000 kms too many?? could i strap on the kit, work it in for a few months, and then swap for a new D16? (i got a 92 Civ H/B si) good or bad idea? and also, can someone recommend a good strait up kit? i was thinkin greddy or apex-i (i don't want an isane amount of HP, but enough to make a decent sleeper)

Oh yea, i'm knew by the way! and i'm not 100% sure on how to use the site yet

Greddy kit is a nice bolt on kit. Edelbrock is a good one too, you'll probably need to make a few modifications to it though since it's for a 96+ Civic.
