    sounds like it was done well.... but theres no way to be sure when you are buying a used car. just look it over very closely, do a compression check, drive it, and hope its as good as it sounds/looks

    So I take it you purchased the car?

    If so, have it dyno'd. You will see where you are making power and where you stop making it.

    Seems to me the dyno sheet shows that it stops making power right around 7500...

    Those are pretty respectable numbers.

    those numbers are really high! i have a similar set-up in my dc2 and im sure its not putting down those kind of numbers. i need to get a few more things am im going to take it to be dyno tuned.

    i am a noob to this frankenstein motor thing too. i have had a couple b16a powered DAs back in the day, but thats it. i have been asking some questions on this forum and others, and most people are telling me that regularly exceeding 7000 rpms is not a good idea. however you are not the first person to show that a b20vtec can make power until 7500 or more. i have heard tales of lsvtecs and b20vtecs running up to 8k or even 8.5k for years on stock blocks but i have my doubts. i have a custom basemapped ecu for my set-up and my car runs real nice and smooth, and it has been a nice daily driver/gas saver for me this first month or so that i have owned it. mine pulls really hard until just after 7k. i have revved it to 8 a few times but shifting at 7.5 is just as fast and i feel better about it. maybe this will help you out

    edit: just realized i didnt read close enough and this car your looking at is not a stock bottom end... oops! even still, theres no reason to rev past the power band
