does this apply to a gs b18a1?

ok this is a quote from the guid sticky at the very top.

“While the guide is a great contribution to the specifics of the DA integra, I wanted to emphasize one very important line from Haberdasher”

Does this apply to a stock 90 up integra gs with that (i think that it is this) b18a1 motor? i mean can i do what they did there to this motor i mena exact parts or am i missing something here?

DA=Any USDM 3 door integra from 1986 to 1993 (JDM to 1992).

**This excludes the GS-R with the 1.7 liter engine).

also included MAY be the 1st gen 4 door hatch
