Hi, i've got an 02 coupe d17a2. All I want is to be able to keep up with a stock type s. Is it reasonable to go the turbo route and hope for this, or is it just better to get the k20. I'm under the impression that the k20 swap would be much more expensive. I drove an 05 rsxs yesterday and it was great, but it made me feel that the little d17 would keep up if turbo'd. Am i way out here? I need help with this, as it is driving me crazy. I love my 02 civic coupe, just want some fun driving power. Please comment.

A turbo civic will eat a type S for lunch and have more to come back for seconds...

A srock Type-S is only a 15sec car. A turbo vic is easily a 13sec car. With alot of mods a Type-S can run high 14's. Get boost. The stock block can take 12psi daily. I did for a year. No problems no compression loss. just tune rich and spray meth.

Do a search on K20 vs boosted D17. I made 250whp on my little D17 w/ stock internals. Most K20s put about 170whp to the ground. If some one says diff ask for a dyno and list of mods.

Agree completely. You should be able to get a turbo kit easier and cheaper than a swap, plus swapped cars can be hard to insure and pass inspection, depending on your ins company and state you live in.

I've run 10psi with no alcohol injection, just running 101 octane and 93 octane for 8psi and lower, and the only problem I had was headlift, cured by a set of ARP headstuds. I've been boosting for over two years and I beat the crap out of that poor little motor. Nothing is harder on a car than Hallett's road course. No problems over what a normal car would have. You just have to keep up with oil changes and be good at routine maintenance type of stuff.

Nothing more fun than beating some cocky kid with a new RSX-s with my "poor little civic".

Yup. I have a long kill list after a year of boosting. GSRs, B18 Hatches, Mustangs, RSX Type-S, 240s, BMWs, etc.......

Now for my new project. 600whp Skyline

yeah its how you want to look at it i guess. A turboed d17 will own a stock type S, but there's more potential in the k20 if you want to build it up. But yeah the cheapest route would probably be straight turbo. You might have trouble passing smog depending on your stats laws.

ok, d17a2, turbo kit such as the dezod, a better head gasket and head studs, I'm guessing maybe injectors? With something like this could i still use the stock fuel system? would i need bigger fuel pump or anything? Really only looking for quality street power. Engine has 30000kms on it and always synthetic, is it reasonable to expect a long life if I'm not bagging it daily.

k20 potential > d17 potential... but so is cost. you can beat a k20 powered vehicle with your d17, sure, but look what more power in that d17 makes you do? sell your turbo kit and buy something with more potential.

it depends on the person. i'm happy with around 200hp in a light weight vehicle, but will you be? and for how long? if i tire of it, i can pick up a beater and turbocharge, if you tire of it you'd have to sell everything.

I would say just got wit the turbo. I'm saving money to go for a full kit and engine build next year. I should be able to put down some crazy power wit it too. Sides, Swap is too expensive and time consuming and if you dont do it right you can screw everything up.

next spring when i get my turbo done, we will defenialy have to go to the track and take videos and all to show how much i own your k20 civic

 
Rep Power: 343

so wait wait, a turbo car running a bunch of boost over stock can beat a stock motor car????? Holy damn!!!

I don't care if a D17 can beat me in a "race" take that puppy to a real track, no straight lines, and lets see how you like that lack of traction and torque steer coming out of corners.

Plus....i have 6 speeds do you? my car revs to 8k does yours? my car can do 141mph....can yours?

just busting ***** of course, do what you want to do and what your budget allows, for me and what i use my car for a swap is a MUCH better thing.

If you plan on drag racing a boosted d17 will be a better choice (well short term at least) cause of the torque on the low end, if you plan on road racing i can vouche for the usefullness of a k20....those guys in WRXs don't expect to see a Civic on their ***

^ word. you should come to columbus next spring. we are having an ohio 7thgen track meet. it can be lots of fun. probally will go to mid-ohio road course then to a drag strip

 
Rep Power: 343

i'd deffiently go to mid-ohio, count me out for the drag strip though

Straight lines make me sleepy...

 
Rep Power: 511

word. check out the ohio forum when spring rolls around cause that is when we will start setting it up.

you gotta take a couple runs at the track though. if anything, i would like to see how you run compared to doubledeuce's k20 7thgen

Your low balling Hawk. When I had just my swap I redline 5th gear at 142mph with 2 peeps in the car, 150mph in 6th gear, with about 1200rpm left (civic speedometer decided to stop at 150????) lol, And that was stock k20a2 swap.

 
Rep Power: 305

how bout doing a k20a3 swap then boosting it.. didnt someone post dynos of there ep3 with turbo @ 300 hp? its alot cheaper than the k20a/k20a2 and still has awesome potential. i for one am sticking with turboing the d17. gonna be picking up another engine to build for boost next week. sleeves,rods,pistons.. already have pnp head, customs intake manifold, bored throttle body. that way i can run big time power at anytime i want. '

complete d17 = $600? max
complete k20a2 = $6000 average
complete k20a3 = $2000-$3000 i've seen them as low as $1500
not to mention custom parts needed for the install. so as far as cost is concerned
d17 > k20

potential
d17 < k20

I had mone for a year. Some members have been boosted almost two year. My year of turbo was @10-12psi of hard driving. I ran 14psi a few times. In the end checked my compression and no loss from the rings. I think the bottom end might be weak. But the pistons and rings never fried. My last dyno was close to lean. car never detonated and was traded in for the Hemi running fine.

Go with turbo now. Keep saving your $$$. One day when you are ready to trade up to a better car, you can still unbolt everything and sell the kit. Swaps are more permanent. Sell the car and the $10k setup goes with it.

Boost is almost a backyard DIY setup if you buy someones used SF kit.mI did mine myself with only help for tuning and final touches. Only had to pay for 2 hours of labor in the end.

On how much psi can a boosted vic beat a stock/slightly modded rsx-s?

 
Rep Power: 0

At about 6psi.

guns, were you running on stock internals?

 
Rep Power: 0

Yup, no need for internals if you are running lets say 10psi or less. I ran 10-12 psi with a few 14psi runs. But I was tuned rich and sprayed meth. I think in the end my bottom end must have taken a beating. But everything held ok. So I say go for it. Just dont be like me and run 14psi.

you gotta understand i really have no interest what so ever in drag racing. It really is stupid IMHO. I'm sorry but no one will ever know what my car does in a 1/4 mile

Just going to add my two cents here...

I love boost on a road course. Once you learn how to use it, you can use it to your advantage: example, Hallett Motor Speedway, coming out of turn 10. I can get off the brakes and floor the throttle in 3rd gear doing about 50 as soon as I hit the apex, the wimpy stock torque give me some speed but don't break the tires loose or affect my cornering... and right at the time I'm coming out of the corner and straightening up, there comes 10psi of boost. With a stronger motor, if you do what I do, you'll lose traction and leave some ruts in the grass. If you don't do it, you won't have as fast an exit speed out of the corner. True that you won't have to spool once you accelerate like I do, but the D17's lack of real power means you can get 4-5mph more before you exit the turn, and then you're in boost range and all 225whp is being put down.

This is of course assuming two Civics with comparable tires, suspension, etc. Only difference being turbo D17 or a k-series.

Now, having said that... in the end, no matter what, the bigger displacement motor will win. You can turbo a k-series and get some damn good power, but that's about $10k down the road. It's all about how much money you are willing to spend, and what you will use the car for and how much it will take to make you happy.

one thing you are forgetting guns.......a boosted D17 will make at least 40 ft/lb's more torque. Torque is what wins races and impresses your friends

 
Rep Power: 607

that is at the crank

 
Rep Power: 343

simple bolt-ons will put a k20 at 200whp

for reference i was talking to one of the guys i go racing with who has a EG b18 boosted who runs a shop, he has a dyno there, after 2 hours on a dyno with a k20 with I/H/E and kpro (i know they're expensive) he got 215whp out of the thing....mmmm k-pro

Wow 140mph on the track... very impressive!!!!!!

by him saying that he just wants to keep up with a stock type S, implies that he will be racing on the street. yes, a turbo civic is capable of 13's with slicks around 8 psi ... but it is not "easily a 13 sec car" on street tires. I would say low 14's with a good driver.

2nd, a stock type S is a flat 15 second car, high 14's for an '05. you make me laugh by saying that an rsx-s with "a lot of mods" will run high 14's. that is utterly and completely bullshit. a BONE STOCK k20a2 swap w/ poly urethane mounts and decent street tires will run mid 14's with a decent driver. a k20a2 with "a lot of mods" is easily a 13 second car. with i/h/e/hondata/itr cams/itr manifold, you can easily run a mid 13, or better with slicks/dr's.

it's funny ... although you put 250whp down, you never posted slips.

i say save your money and just trade it in for a 06 si. There rumors there its going to be close to 200hp stock to compete against the srt-4 and scion tc. If the 06 si body is ugly then i say do a swap. I prefer N/A over turbo but thats just my opinion.
