You need to get the right bits for it... However, many moons ago, when my car was about 100k km younger, I'd done bolt-ons ecu + suspension. All up it was about 3k's worth of parts, and the car was great. In fact, after back to back driving against my mates ITR, i was very happy with the VTi-R.

This all ended when all the rubber parts shat themselves due to abuse and old age.

End of the day summation- the fundamentals are there for a very good, very similar package to the ITR. You will always be missing a couple of key components (thicker subframe, thinner front glass) but the rest of it all gets changed during the modification process.

I think the ideal package would be an ITR with a good header, good intake and good exhaust (quiet) along with a hondata/crome/pfc. Leave it like that and enjoy it. You maintain what is one of the best factory packages around and liberate a few extra kw, without destroying the character of the car
