Nitrous will be a temporary solution. VTEK motors suck, they simulate turbo lag but they don't have a turbo. I don't know much about ricers, I doubt a 4 banger can withstand this but:- Bore the motor (new pistons, cranks, valves, and seals required)- Add the bolt ons that give you a little something, intake, exhaust.- Headers and ChipI don't know much of how they crank alot of HP out of the ricers, I personally like domestic cars and two cars are currently being built at my house. A 435 hp monte carlo and a 255 hp (just a stock 350 vortec) z28 camaro.

Ok the guy before me gets a thumbs down. Its Vtec and its not like turbo lag and it doesnt suck.Everything that can be done to a v8 can be done with a 4 cylinder. Stage 3 camshafts boring sleeves pistonsrace bearingsport and polishexhaust intakeheaderthese are all ways to ungrade the hp of your engine.

First off Johhny R is a moron. If Hondas "VTEC" motors suck so much, then why is it they can go 200,000 miles without being rebuilt, yet you have to do a complete tear down on a Z28 Camaro before you hit 100,000. Second VTEC isnt simulating anything, it is changing the cam profiles and timing. Third, its funny that your "255 hp (just a stock 350 vortec) z28 camaro" is an 8 cylinder, yet the 2008 Civic Type-R is a 4 cylinder, naturally aspirated, and puts out 240hp stock. Wow, so Honda can make almost the same amount of power with half the engine size. Or you could go with the All motor 2.0 litre that the guys at Honda Tuning build not too long ago that put down 318hp. Yes, 318hp out a 2.0 litre 4 cylinder naturally aspirated engine. Please explain again how domestic is better.Anyhow, to answer your question, there are many things that you can do to get HP out of an NA Civic.Most of which the post above me already hit on, but he didnt mention a blower, which is very common is all motor Honda applications, upgraded ECU, Hondata intake manifold gasket, performance clutch and flywheel, individual throttle bodies, larger fuel injectors, fuel rail, fuel pressure regulator, upgraded fuel pump (the last three wont increas horsepower, but will be needed if you upgrade the injectors). So much more that I just didnt think of.

I'm not sure you can do all that much with out a turbo, but you can make it go pretty quick. Any car can be really fast with money.

a vtec engine is good. its throws in an extra kick at a certain rpm.you can always adjust when it kicks in with a vtec control. an si you dont really need turbo. anything you can do to any engine can be done to a honda, bore and stroke, port and polish, pistons, piston rings, gear, cam, intake, exhaust, any internals you can think of modifying you can find for a honda especially the 92-95(5th gen) and the 96-00(6th gen).the real help will be the port and polish with the bore and stroke. and any other internals. set it up like if you were going to get turbo but dont get turbo and it will be nice. dont NOS that shit because it wares the engine down alot and you wont have it to reliable. also if you can get an LSD for it go for it and you will be good tranny wise.

Engine swap is the first thing you'll have to do. I think everyone else who has answered so far has forgotten than the '95 Si comes with a SOHC D16Z6 engine. That engine is pretty limited when it comes to naturally aspirated power. So if you chose to use that engine, you'd end up spending more $ than you would on a swap, you'd have a very high compression engine, you'd be using race gas only, and it wouldn't be very good for driving on the street (all of this for having high hp like you stated). In the end, you still won't have as much power than just swapping in another engine. Start with at least a B18C1 engine, but the engine should be based on how much $ you're really willing to spend. A K-series engine would be the top choice though. A K20A swap could put you in the low 13's to high 12's in the quarter mile; with just the stock engine.
