Turbo for d17a1 vs d17a2
I've read reports that a d17a1 with a CAI will get the same or more output than a D17a2 + CAI. However, for turbo purposes, will d17a2 have more potential?
Are there vtec cams that can give good reliable daily driving and good FI flow up top? This is possible in theory, but just not sure if it really works.
The point is, I'm looking to buy a 7th gen civic, but not sure whether to look for ex exclusively.

Ppl will argue that the LX/DX will be better to turbo due to longer gearing than the EX and the EX is better due to vtec but personally I don't think its that significant. I'd shoot for the EX bc aftermarket parts are easier found for the EX. Bolt-ons don't do much for power with the civic. I'm running the stage 2 N/A cam and its fine for daily driving you just have to live with a lopey idle. Alot of ppl love the stage 1 cam. Good luck.
i'd say it's up to you and how much you want to boost. iirc:
ex = cat converter is down & out of your way, more parts (perhaps), shorter gears, etc...
lx = longer gears & lower compression ratio

Rep Power: 305 You will get more power boosting the D17A2 because of VTEC. It has been proven that VTEC equiped motors produce more power vs engines of same size without. It is true also that there are cam/head packages widely available for VTEC motors and the only ones available for non VTEC are mostly custom ordered.
You could always have the A2 motor and use the A1 tranny. VTEC + longer gears. Thats what im going to do.

Just test drove a 03 lx this afternoon. The stock performance is really not that great. Asking price is 10k and it has 45k. I expected better interior, and there's no remote entry for this car. I'll check out the EX next.
Any major changes between 01-03 civics?
Think $3000 can get a decent custom kit?
Turbo $600
Manifold $250
IC $250
Charge pipes $400
Custom down pipe/flex pipe/exhaust $500
BOV $150
Cone Filter $50
5th injector $20
E-manage/boost sensor/wbo2 (got it)
Crower d17a2 stage2 boost Cams $300(?)
Adjustable cam gear
+ fittings, misc

Rep Power: 256 ive got an 05 lx coupe with a d17a2 swap and my a1 tranny and vafc-ii. just got it running today with no bugs. vtec is way better than my a1. i was just going to do an a2 head swap but i bent the rods in my a1 so i just swapped an a2. my lx has remote entry and rather nice 2 tone interior. white car, brown/black interior. the sedans are nice too. if you want to work on one right away, i would buy an lx and swap and a2 with the a1 tranny or just an a2 headswap. if not then go with an ex. theres plenty of parts available. just get ready to do some converting to ex **** if you get an lx. dezod has really came through and gotten us some good parts on the market.

Everything looks ok except, don't use an extra injector, just use 4 RSX ones.
The crower cam setup is more like 700 because you need the valvetrain too.
You'll also need oil lines and the $1000 or so worth of nickel and dime parts that you'll also need. theres parts for the A2, but you need to tune for the high cam and the low cam, no vtec makes tuning easier. Problem is you can have a cam for high revs, or a cam for low revs, and you'll sacrifice one or the other.

With regard to the differences between the 01-03 civic they are the same car. However I owned an 01 sedan and have an 03 coupe now and Honda came a long way in those two years in providing better inetior and fit and finish (fabric in the seats, less road noise, etc.). As with all cars if you get them after the first year of the model launch you usually get more value for the same money as manufacturers typically include equipment that may have been options in the first year (remote on the civics for example). Plus after the first year they have worked out any bugs the car may have had (leaking struts on the earlier civics).
As the model run continues on manufacturers have to toss in more value added goodies as the shine of the new model has worn off and other manufaturers have probably developed sexier offerings.
All together between the two cars I put on more than 400k (220 on my current one, over 180 when I traded my 01). Both reliable cars, not fast out of the crate but overall very bullet proof, my 03 runs like new.

Rep Power: 403 Yes, its easy to make 500 whp on a k series motor, although not as simple as slapping on any old turbo, its going to cost a hell of alot more to do that. When I said big numbers, I was speaking comparatively between the d17a1 and d17a2. My point is you don't have to drop 5k+ alone on a k series block then another 4500 on a turbo kit to make good numbers.

I say go with the LX. I think the vtec will complicate tuning with two cams, and the LX wil be cheaper to buy anyway. As for any marginal increase in performance with the vtec on an N/A motor, after you boost, that difference will be minimal. Someone mentioned having to convert to ex cat, etc. A lot of people are running turbos without a cat, and the header is going to get swapped out anyway as part of the turbo setup, obviously, so I don't see that even being an issue. This all coming from me reading up on this site, considering a turbo. I am, however, a relative noob, driving an almost stock, N/A car, so take it for what it's worth. Good luck.

you can always vtec the A1 engine and bore and stroke it and beef it up. There's nothing like running a custome built engine and parts are starting to show up more for the A1. I Guess its all about prefference and how much work you are willing to put into your car.
Re: Turbo for d17a1 vs d17a2
LMFAO lol yeah what he said and if anyones intrested im selling a cheap k motor 
look at the siggy but boosting a d17 just depends on how much you will be working it...are u willing to do pistons head work i think the only advantage is the tranny on the a1 i have one for sale also in my siggy

How exactly would you go about stroking a d17? What parts are starting to show up exclusively for the a1?
