Just seems a bit odd. You started asking for advice, when 2 people gave you what looks to be real world answers, you asked if their cars were ok?! Crazy!
When i did my original build, i wasnt fussed what power it would have made. Picked a turbo and balanced everything else to it, and thats about what im doing again.
You have an idea in mind, but no way would i be gutted if it made less than another persons similar car. As long as it drove ok, and better than BPU, i couldnt care less!
So you are telling me, if you build it up and it makes 549 at 1.6 bar, you will be pissed off?!
