Si Turbo on Civic HB Sport

Hi,

I have the opportunity to buy a lightly used Si turbo for my civic HB.
While the stock turbo is fine, power dies off past 5500 rpm, and the Si turbo goes to 6500, hence the interest.

My question is, on my tuning tables, which maps am i going to have to adjust.
I know Max Pressure for the turbo and i am guessing the AFM, but looking for advice.

Thank you.

nothing needs to be changed

The Si turbo is not worth the upgrade unless you get it dirt cheap

Si turbo does not pull to redline

I guess it doesn't pull to redline, but it pulls to over 6K, as oppose to the standard turbo that drops off after 5500.
It would be like $400 to get the Si turbo, still think its not worth it for that price?

not worth it but that's just me
better off saving for the 27won turbo or PRL

you are better off getting a custom tune than buying a SI turbo
