Before putting 300whp to the ground...think about 220whp or so...220whp on a 2300lbs car will get it moving...you'll want to upgrade the clutch and flywheel on the tranny...and if you are truely wanting to put down big power numbers like 300whp...think about getting an LSD for the tranny or buying a tranny with an LSD already (the JDM B16A and B18C had an option for an LSD)...Quife and Cusco make good aftermarket LSDs...remember...300WHP is all great and fun but if you don't have traction and you spin tires through the first 3 gears..the power does no good.

300WHP is a LOT for a lightweigth car like a civic. It sounds all fun and great but you may find you'll be fine with a lot less. As I said...220whp will get a lightweight car like a civic moving. You don't have to have a dyno-queen or the fastest car out there...all you really need is enough to suit you. 300hp is a lot for a 2300lbs car, so make sure you know how to drive it in everyday traffic before you do it. You may get it and find the wheels spin too much for your taste...all of a sudden driving it daily is no fun...If you go for broke like that seriosuly consider an LSD.

You can keep A/C with any B-series swap...I know for the 5th gens you use the Del Sol Vtec A/C bracket to mount the A/C if you want to keep it...I am not sure if you use this one for the 99-00 Si A/C bracket if you want to keep A/C. I can check, but I'm pretty sure it's one of those for the 6th gens also...Keeping A/C and PS shouldn't be an issue with a b-series wap if you want it. Now if you want to keep A/C once it's turbo'd...you'll need to be careful choosing the turbo manifold. Most likely you'll need a log-style one among other things...those fancy tubuler ones will likely mean no A/C.
