Anyone done it? Thinking about doing it on my car for some extra power.

Most people I know have been doing external bolt-ons, tuning and FAI. The motor is good up to 250-300 WHP on the stock internals.

No one on CSi has actually done it to the current gen Si. I think Habanero Sedan is considering this as his next mod, but I could be confusing him for someone else.

I'm already turboed pushing 271 WHP at 8 PSI... Just bought new injectors... My goal is 300 WHP.

I asked on 8th civic and it seems to be a 50/50 saying I would gain power and the other half saying waste of time.

Moving to the Got Boost section. You might get some good answers here.

ported heads on a FI honda is pretty pointless. plenty of guys making 700+whp on stock b series heads.

get a 3" exhaust if you don't already have one, and just turn up the boost a little!

Yeah the 3 inch should really help. I'm running 2 1/2 right now. I really don't want to go above 10 PSI.

It sucks being in the desert because I cant physically see my car.

Easy power = full 3" exhaust and turn up the boost.

Hit 300whp easily enough.
