I know you guys might read this off other section on this site, but I just need more local opinions about this.

I have been struggling on this swap and turbo thing for a while, I thought I might need some help to make my freakin decision, I am stuck in between.

1st Option: Completely swap K20 JDM engine (which comes w/220HP) all motor probraly run at 200 whp with civic 02 Ex body weight. Which I know for a fact has alot potential which can be view its future potential here: http://hondawerx.com/modifiedk20.htm

Civic 02 Ex
Street Tuned Expectation w/k20 swap: 200whp with alot potential
Confirmed money invested for now: $5000.00

2nd Option: Base on D17 stock motor, bolt on complete customize turbo setup which runs max 11 psi w/alcohol injection just to be on the safe side for the motor to last as long as possible, with internal modification (clutch, flywheels, dual crank pulley, cams) with no further potential and engine won't last as long as K20 swap would.

Civic 02 Ex
Street Turned Expectaition w/turbo setup: 180whp-250whp with no further potential and disadvantage of turbo lags.
Confirmed money invested: $5000.00 ($4Gs on turbo and install and another $1G for internal parts)

Street quarter mile summary: Just in case if I need to compare these 2 setup on a street quarter mile race, civic stock D17 motor w/turbo range anywhere from 180-250whp after the setup with internal, probraly will average around 250whp true power compare to 200whp with k20 swap, however I personal think when you race aganist all motor engine (in my case k20 engine) you have to lower the turbo setup from 250whp to 230whp because the fact of its turbo lags which won't kicks in after 4000 rpm and all motor has the advantages at the beginning. But whichever way civic w/turbo will still beat the k20 don't know by how much, but knowing the fact that d17 w/turbo setup has no potential left and just went as much as it can go, however K20 all motor swap is whole different situation where can setup with greddy stage 3 turbo setup and internal modification (alot) and in fact can setup up to 25psi depends on internal of course.


Above are just some of my personal summary, please correct me if I am wrong, I'm not a pro at this, but expect everyone who knows about this issue to help me out little bit about making my decision. I appreciated for all your time, but no haters please. I have nothing aganist D17w/turbo setup nor k20 engine just my personal opinion, but if you think otherwise please correct me.

well, I do know if you go boosted the turbo specialties kit comes w/a t25, or optional ball bearing t25 so they really will be little if any lag(small turbos spool quick, why run a t3 when we cant boost past 8psi safe, or 10 psi w/water injection????

anyway, theres my $0.02

you know, a built d17 can handle 25psi of boost too. it's not like the d17 is anti-building or something. you might want to read the forced induction/swap forums, since the texas forum isn't the only place for you to read about things on 7thgen.

when you say that the k20 has more potential, this is prob true but, if you stuff a k20 into a 7th gen engine bay, and i do mean stuff, where are you gonna put anymore "potential"? I have seen and heard that putting a k20 in a 7th gen is like ron jeremy sticking it to a midget!

just my $0.02 also...

yup, and most guys that have swapped a k20 might have reliability issue due to the fact that the crossmember thats holding the engine in is not built for the k20. I know a lot of these guys have already swapped and have been doing good, but see how their car performs after a few years... The new 2.0l thailand civic has a new crossmember to accomodate the k20 inside, you need to get a wrecked 2.0l civic and bring it over here in the US, but that would proabably too much problem for you.

seems like more people shot fot turbo than k swap, it's not I don't like turbo, I am worrying about the reliability, I spoke with SF turbo with certain upgrade such as equal length manifold, bigger size turbo and alhocol injection will run around $3500 shipped I know for a fact will run about 11psi on a safe side probraly 189-200whp but I am worry about the reliability of the motor as a whole, like in 6 months or 12 months, more chances motor will blow up and I have end up spending more money. If I boost up to 25psi which I will if I decide to do the turbo probraly won't last even longer with 12 months. any suggestions on here? If I run k20 all motor which I know for a fact will last pretty long, about angel fitment, and not fitting correct, I will get customize motor mount for 7thgen, bodywise it will fit alright, electronically wise everything will be included such as harness, transmission, ecu etc.....

let me know if I miss out any parts, correct me if you will. thanks guys.

well if you go with a k20 the k20 sits to the far left of the engine bay in the civics... ive seen the k20 swap... and its a tight fit... but if you build the k20 and make it NA or something along thoes lines then you can def last a long time... as far as turboing the stock engine boosting it at 25psi all day long will def kill your engine quickly.. but you could set it at a low boost for around town, but then daily driving it would become a issuse with the swap since if you go NA idle problems might show up with the k20

why do you say k20 would be a issue w daily driving ? it is all motor.

there shouldnt be daily driving problems with the swap if its done right.

in talking to SF, the D17 isnt the first turbo system they have released. As long as you maintain the FI engine things should operate fine. The systems from SF have been used for a long time now and havent had any problems unless of course over boosting etc. IM going SF personally. Not looking to boost over 10 to 12 tho, i just want more HP

nor should there be daily driving problems with turbo, if it's done right.

therefore, in conclusion, JUST GET IT DONE RIGHT and you'll be happy

K this is what I'm looking for...tell me how long do you think this will last me....First off I wanna see 13.6 or low 13's or high 12's...so I was looking to getting the SF kit, with alcohol injection, upgraded turbo...eventually i want to pnp, DHRacing Cam and pulleys and maybe some other mods down the road like upgraded clutch and flywheel and upgraded throttle body...with MY (basic) SF turbo set-up will I achieve my 13.6 to low 13's goal? Okay if so, what does the reliability look like on my motor down the road...I want to see 13's...what is necessary? I want to be fast and reliable...I'm reading all you guys posts and some say its reliable and some say its not...only time I plan to turn up boost like around 10 is only at the track...looking to run 6-7 daily at the most...how does all that sound?

EDIT: What can I achieve by going all motor? What mods would be necessary? What kind of horsepower would I put down?

all motor i say you can get 300hp(on the k20) , turbo charged you can get about the same but its going to be high psi...

sorry if I confused u...not looking at getting the K series...just either turbo or NA D17...don't really have the necessary funds for all the hassles with the K20. thanx though.

If you want to have the power that you want, dont bother with buying a kit, do a custom job. Just find a good shop to do your piping and dont buy cheap parts.
