Default Options for Better Braking for 94 Honda Del Sol?

I have a quick question on brakes. I have a 1994 Honda Del Sol with a B16 turbocharged. The other day i was driving down the freeway, and hit a light at the dreaded "Do i gun it and make it or do i slam on the brakes and stop" point. I chose to slam on the brakes (after all accelerating from a light is alot of fun right). I got stopped before the line but not with results i like inparticular. Here is the situation:

65mph speed limit and I was going roughly 68-70.

About i dont know, say 7-10 car lengths away from the light, it turned yellow.

I got stopped by downshifting to 4th, then 3rd, (using engine rpm to slow me) while HARD braking (modulating myself as i dont have abs). about a car length from the line i lock up the brakes completely and skid to a stop. at this point i think instinct kicked in because i must have pulled my ebrake as well lol. (went to drive away and was locked haha. ."what the..?!? DOH!!)

Brake pads had plenty of time to be warmed up as i had been driving a while and had used them plenty going through a town shortly before hand.

Although i got stopped, im not really impressed with my brakes, and im looking to get a high horsepower tune here shortly. (Freshly rebuilt b16, sleeved, and built for high performance. Goal is 450-500whp) Im at rougly 200whp right now so i know that this braking will not be satisfying at all, except for normal daily driving, with the higher horsepower.

What can I do to improve my braking realativly inexpensive? Do I need to think about shelling out big bucks for high grade big brake kit? I dont want to have to change my wheels but i have 15" rims now and most big brake kits need 16" min. .

My brake setup as of right now is:

OEM 10" solid rotors in front, OEM calipers NON ABS

Rear Disc Conversion from drum brakes in back

-9.5" solid rotors, "OEM" calipers as well.

Goodridge G-Stop Braided Stainless Steel lines all around.

Stock master and slave brake cylinders (unsure of actual size)

Using a Mid level STREET brake pads, thinking ceramic but again not sure

Rotors and Pads are all basically new. Only a couple months of easy driving on them, with rare hard braking, and even more rare extremely hard braking.

Brake feel is awesome apart from the performance under extreme braking i experienced a couple days ago. I havent had to brake that hard in a while and again I am dissappointed in the results. Pedal feel is also awesome. Very responsive and i feel i have alot of control over the brakes.

I have read into "modifying" some of the better OEM brake systems such as Integra TypeR 11" rotors/calipers. But i dont feel comfortable actually drilling rotors and shaving caliper braces. I just think that leads to more risk than reward. (especially if im the one doing it haha)

Also I read that even though my del sol isnt a super lightweight, its light enough and coud be a contributing factor, as well as my 7inch wide contact patch and decent all weather tires. (nothing super sticky but they do well enough gripping in a pull with 200hp)

So what are my options to getting a little more performance?

@Sky- yeah the crx is insanely light... Now corect me if im wrong, but drilled/slotted rotors wont have any real significant change in braking performance minus what they are designed for. . drilled=heat dissipation and slotted=water diffusion. So the slotted would work better in moisture and really drilled wont have virtually any STREET performance advantage over solid. Not to mention structure advantage of solid vs drilled. . Not saying your set up is bad by any means, just from what i know and have learned. . in a street set up. . performance is: solid rotor is equal to / advantage over slotted/drilled. . If i were planning on doing more track days or autox or something then maybe i would go for slotted/drilled. But this is just a really fun Daily Driver.

@timber.matt- preludes have a 10" rotor as well dont they? as for calipers, i guess im asking what is the best compatible/minimal modification brake/caliper set up that i can find without paying $$$ to get.

I drive a modded Crx, so believe me I know what you are talking about but worse... You can either go buy some Brembo kit or get some off a ITR as you suggested, or go buy some drilled/slotted rotors. . I have drilled and slotted rottors, and it makes a pretty big difference. I am at about 200 horsepower(on my b16 aswell but all motor right now) Just save up and make sure you do it right as you don't want to be skidding into a stop light again.

you could just get the brakes off a prelude, they are bigger. or get the brakes off an Acura legend, those are 2 piston brakes for the fronts. A lot of fifth gen prelude owners put legend brakes on for more stopping power and they bolt right on. But you have to put them on the opposite side so the bleeders point up when mounting and that requires you to get longer brake fluid hoses to the calipers. Not totally sure if they will bolt right to a del sol, but a ton of Honda stuff is interchangeable and you could just get the mounting brackets off the car you get the calipers from. besides for that always use good brake pads and rotors
