I am going to be doing something to my 01 civic ex soon. Should I put a stock k20a3 in the vic, or should I turbocharge the D17 at 6 psi? I might end up doing the header and intake to the k20a3, but if I do the swap I wont be able to afford anything else. Which is faster, a 01 civic ex D17 turbocharged, or a 01 civic ex K20a3 (stock) swap?

Depending upon the set-up of the turbo system and boost levels.

T3/T4 Hybrid turbo D17 @ 8 PSI > K20 w/ I/H/E

T25 turbo D17 @ 8 PSI < K20 w/ I/H/E

hm.

t3/t4 hybrid d17 @ 8 psi > K20a3 i/h/e
t3/t4 hybrid d17 @ 8 psi < K20a2 i/h/e

imho

ehhhhhhhhh

Even an A2, the D17 would probably win or edge out from the K20. K20A's with I/H/E are only putting down 18X WHP. I have seen T3/T4 Hybrid D17's throw down 180-205 whp at 8 PSI.

I say go with the boost. the swap and I/E/H aint gonna get you the type of TQ boost gets you.

I can only think that the swap would wind up costing a **** load more as well.

k20a3 you get about 165whp with various bolt on's. it's more reliable but i think they both cost the same in the end. Here's a checklist of stuff you need for the swap http://www.hasport.com/News/Articles/ESK1parts.htm

show me a 180-205whp dyno of a t3/t4 d17. traction appears to be a problem with turbo d17's ... I've seen a vid of eternalblue civic's t25 turbo d17 and he has ridiculous traction problems and something tells me he's not putting down 200 whp, but I could be wrong.

here are some nice k20z1's ...

I retract my previous statement ... turbo t3/t4 hybrid = driver's race with a k20a2 i/h/e ... but k20a2 i/h/e/hondata > t3/t4 hybrid

but u see... you can turbo a k20a? and it will smoke a d17turbo like nothing...

I am making 190whp on a d17a2 T3/T4@ 8psi with a conservitive 11:1 tune. I'll be going back on the dyno next month with some alchy injection in hopes of hitting 210 @8psi.

 
Rep Power: 362

you also have more than just a bolton turbo kit though.

edit: I just realized ... why are we arguing 8 psi? ... the original poster asked about 6 psi

imo, 6 psi t3/t4 d17 = drivers race with i/h/e k20a3

drivetofast dyno'ed at 155 whp at 5 psi with his sf turbo kit. another member dyno'ed 185 whp at 8 psi with the same kit

A T25 can beat an a2 with proper tuning easily lol

ha! guess you haven't seen my times. An a3 with i/h/e is what, a mid 14 sec car? I pw3nd that!

Example: CrewChief ran a 13.6 @13 psi on a ball bearing T25. Pretty overwhelming fight for an n/a a2

read your statement again. 13 psi.

if you wanna post wrx-boost leveled d17's, then let's add some more boltons to the k20a2

k20a"2" w/ dc5r cams, i/h/e/kpro ... 13.6 .. may I remind you that this is in a FULL interior rsx ... and you guys are running weight-reduced civics.

want more? I can do this all day.

good lord, lets not be so defensive

Meh you know what in the end we spent less lmao

until **** starts breaking and you have to replace parts because turbo'd non-turbo motors will ALWAYS have more issues compared to non-turbo'd motors or cars that came with factory turbos. And no one can say otherwise. Talk to me when your motor hits 100k....if it does.

And also to make a second point, to get a Turbo D17 to compete in a straight line race with a Turbo K20 is gonna cost you ALOT more money then it would to do a swap and turbo it.

If you look in the long run, not in the ricer perspective of "more power for cheap" a k20 swap pwns a D17 turbo.

the end.

^^Well, you know, it's all a hit or miss, I mean shoot it can happen to any motor, boosted, un boosted, or Ford lmao

run a turbo d17 and a non-turbo d17 on a dyno until they blow up and find out which one blows quicker. And i'm not talking about a fully built D17 either, i'm talking a bolt on turbo kit at 7psi.

Sure any motor can blow up, but a improperly built turbo motor will blow alot quicker than any motor.

 
Rep Power: 397

BTW Hawk, some people want to keep the original power plant in your car. Wen you beat someone it would be alot more satisfying (to me) to say yeah it's still a D17 (Even though it's boosted) than oh yeah I scrapped it for a more powerful engine. I mean I'm not hating but the whole car scene is a "do what YOU want to do" scene. I would like to keep the D17 instead of swapping, you wanted to swap. Were still both 7thgener's at heart, we just have differn't goals. =)

 
Rep Power: 344

For me it wasn't a matter of swaping in the more powerful engine, if that was the case i would have swapped a k24, its gonna make alot more power than a k20 when its worked. I did the k20 swap because

1. it was cheap, 5500 bucks aint bad for what i got.

2. i know its a better built motor and it would/will wistand what i do to it alot better than a turbo d17.

3.) 6 speeds and 8 grand is fun

When my old motor died i was planning on buying another d17 and turboing it, then i began to do some research about the swap and one kinda fell on me. I really doubt i'd be road racing/auto crossing if i had a turbo d17. Torque steer is not fun when your road racing.

 
Rep Power: 397

I went the route of turbo because

1)Show reasons (Works both ways for k20 or turbo)

2)I'm only keeping my car for a eyar and I can unbolt the turbo and sell it as stock

3) Your right about the turbo and road racing... and I can't hink of a third so I'm just leaving this one out lmao

 
Rep Power: 297

2)I'm only keeping my car for a eyar and I can unbolt the turbo and sell it as stock

make sure you let them know at least that it was run with a turbo, cause there will be more wear on that engine and otherwise thats not being honest.

Thanks for the lesson in morals There's a shop near me that buys and sells modifyed cars so I'm gonna see how much they will offer me when the time comes
