The B18C5 will drop right in. There will be more work with the B20/VTEC. IMO, stay with the GSR motor. As for what you need to do to reach those numbers, REBUILD. Drop a Type R crank in with some Crower rods, or rods of your choice. The GSR compression is a 10:1 so you might wanna raise it some. Don't go any higher than a 11.5:1 compression or you'll have to run on race gas all the time. All new valvetrain. Personally, I'd go with Skunk2 but you could also do TODA. With Skunk2 get the high compression valves, retainers, valve springs, STAGE 3 camshafts. When you get your PnP, you'll wanna get a 5 angle valve job while your at it and port match your shit. Skunk2 IM and I would go with a 70mm Spoon TB, but your choice. AEM V2 intake, a 4-2-1 header, and any brand of exhaust really. I'd go a DC 4-2-1 header and Skunk2 exhaust or Hayame. Also, I forgot to mention, when you're getting your head PnP, you might wanna think about getting your block sleeved, make it stronger. Fuel system is next, then you could throw pulleys on there. Lastly, HONDATA S200 ECU chip will make your power jump and work really well. Don't forget that having all this power is good, but if you can't throw it to the ground, its worthless. Build a good suspension with Z rated tires. If there's anything I'm missing, someone else will fill you in.
This is all something I would do. There are many different ways and brands you could use. I choose Skunk2 cuz I know Skunk2. TODA i hear is good, but I don't really know how good. They have on their website an all motor Honda running 9.99 quarter mile. That could be with a stripped car. I'm guessing your going with daily driver, like most of us here. Last, do research before you buy and start building. Know what you're buying and know what you're doing. Don't do it cuz someone says to. Knowledge is everything.
