Building a racecar or just a street machine? I know that platform and motor pretty well, happy to offer my $0.02.

It’s currently a ITB car. I’m considering adding power to the car and installing a 4.9 final drive and a baffled oil pan

I guess my next question should be: Are you remaining in ITB, moving up to Prod, or building to another ruleset? That will pretty much determine what you can do to add power. Much of the D-series engine stuff crosses over as far as intakes, camshafts, and pistons. Getting cool air into the engine and a proper header/exhaust system pays dividends, as well as some type of programmable engine management. There are some connecting rod options, and valve springs as well, which would be necessary if you plan on running much past about 6500 rpm. Baffled oil pan is good, an Accusump is also worth every penny.

Suspension mods? Lots you can do there on that platform as well.

Let me know what class/ruleset you plan on running, and I'll send you an email with more details-

Perfect. The limited prep D15B7 is almost exactly the same configuration I run in my car in GTL trim, and I run it full prep in FP trim. I'll send you an email and we can continue discussing that way-

Depending on how crazy you want to get, I have control arms, trailing arms, sway bars, etc built for the Integra, but those parts cross over if need be. Can build brake package for you OE spindle since they are the same.

I would look at a different gear than the 4.9 unless you are just going to keep it stupid simple and not worry about gear spacing inside the box. Sell the Konis, toss the poly and step up to real race suspension designed in the 21st century. Koni yellows are glorified street car shocks.
