i have an '002 ex.  the warranty will expire at 100k miles. if i put a turbo kit on there, how does that affect the useful lifetime of the car?  

what kind of a turbo setup are you thinking?

for a bare bones setup, you'd need turbo, manifold, BOV,  intercooler, controller, timing, and injectors.

the more power you're looking at, the more stuff you'd need. you'd eventually have to get wastegate, Map sensor, downpipe, piping, Air filter, Oil lines, Fuel pressure regulator...

and depending on your motor, you might need some of this stuff anyway.

I think the '01 and up Civic EX has a D17A2
There is one popular setup for this engine makes about 170 hp at like 6-8 lbs of boost i think, but i'm not totally sure what parts it onvolves.

so what kind of hardware did you have in mind?

i don't know too much about hondas, you might want to join a 7th gen. civic forum. This engine is a bit dated, so there are lots of enthusiasts who know alot about it.

The D-series isn't a great engine, and really doesn't have alot of potential, even with forced induction, so are you sure that F/I is the route you want to take?

if so, hat size turbo were you thinking? is there a specific kit you're looking at?  

oh, any engine modification, including F/I, will void your warranty.

too much boost will blow up your engine.

and F/I cars typically don't last as long as N/A cars, because forced induction is hard on the engine.

They also tend to be a bit less reliable.

hope i was able to answer your question  

I've never modified before, so i really don't know whats out there.  i did find kits out there that had most of the components you mentioned. i think it adds about 50-55 HP. But i have heard that once you modify one thing, you do have to upgrade other engine components, so if thats the case, i probably won't consider it. I'm just worried that i'll get it and only get a year out of the car due to the added forces the engine sees. I think the kit was close to 3 grand  

once you get into major power adders or do extensive engine work, you also have to strengthen the transmission, which is expensive and painful work. I think you'd be smarter to tighten the car up before you think about adding power. maybe bolt up a sway bar or chassis brace, or consider coilovers, suspension is always where i start modding a car.  

I also have an 2002 civic ex. I have found pleny of turbo kits. Try www.procivic.com They have a nice turbo setup made specifically for the D17. Also a website called www.dezod.com. Both websites are D17 specialist. As long as you dont keep the boost to high then you should have no problems with the life of your engine. Just make sure always get your oil changed and other things for longer engine life.  

I'm not much of a honda guy, but I'd save the money and instead look into an engine/tranny swap rather than f/i.  I don't know if a KC out of an RSX would fit or not, but i'd be willing to bet you'd get more power out of that with less hassle than if you ran f/i on your d-series, or look into swapping engine/tranny from the same year si...  

really to tell u the truth... your gonna need alot under the hood before ever considering a turbo kit... ur gonna need for starters... headers, exhaust system, cold air intake, forged pistons, rods, crankshaft, camshaft is optional... adjustible cam gears if u want new pulleys, timing belt, rebuild the whole top and bottom end... if you dont have forged pistons and rods your most likely going to put too much stress on the engine and literally melt the stock rod right to the piston and the piston will be at the bottom of ur block fried completely... its going to cos alot of money to just get to the point of getting the turbokit which then cost anywhere from like what 2000 to 5000... you really dont need the headers bcus thats going to just be taken out when you get your turbo manifold but its good to have for the time being... if you really wanna start racing street or track then yeah its good to start but if your looking to dump the car soon... dont even bother... + ive got a d16z6 engine in my '93 si hatch and im dumping out the engine for either a k20a2 or a b20a2 soon... then im just going to turbo that... reason? why turbo a single cam engine... and the engines got 127k beaten miles on it... im just telling you... unless you really wanna race and uve got a spare car to drive while ur civic is getting the work done... dont bother its too much time and money and ur not going to get near as much money back when you sell it... then theres the labor too... so just sell it and lease an sti or something... sorry to brake it to you...  

oh yeah i forgot.. your going to need a new axle or whatever theyre called ont he civic i forgot and a new transmission and shocks struts strutbars and reinforce the frame bcus its gonna twist like a *** off the line...  

www.livetospeed.com has amazing turbo kits that can give you a lot of hp without having to boost that much and they give you everything you will need. Plus its cheap!!!  

i'd suggest to not do anything yet before your warranty expires if you're not sure what you're doing. that's money down the drain if anything happens to your car. and i like the civic. don't wreck it...
