Concept 2002 Honda Civic Coupe:

Based on the 2002 Civic Coupe, the Honda Civic Concept answers the question, "What would a factory-built high performance Civic Coupe from Honda be like?" Starting with components from Honda's high performance parts bin, the Civic Concept uses suspension tuning similar to the new Sport suspension package from Honda Accessories. Meanwhile, significant engine enhancements raise the horsepower and torque of the current 127-horsepower 1.7-liter engine to 170-horsepower through a custom high-flow intake manifold, a stock engine head that has been ported, polished and decked, a custom exhaust header, a large 2-inch exhaust system and a sport muffler. Braking power has been enhanced through the addition of 4-piston Brembo calipers. The car rides on 18x7 wheels and 225/40-18 BFGoodrich tires. The Civic Concept's ground-hugging demeanor is achieved through a prototype ground effects kit. Appearance is also enhanced through special blacked-out headlight frames, a carbon fiber sports grille, a racing inspired rear wing and a carbon fiber rear diffuser. The interior incorporates deeply bolstered Recaro sport seats lined with Alcantera Suede and interior trim pieces, a high performance gauge package, sport pedals and a three-spoke sport steering wheel.

Just wanted to share this, because I found it to be ironic, I mean...Honda was promoting a concept EM2 version that would put around 150whp with the listed mods, but those mods have already been tried by many users from this forum and those results have never been reached.

Would a "high-flow intake manifold" make that much of a difference?

 

Our intake manifold does suck, but on an n/a car it would have to be completely different from anything out there right now to get any gains. I wonder what happened to this exact car, if its out there, Id love to find the owner or talk to the designers....any inkling at all about how this thing was built or where it is. I might have to start emailing and faxing honda nonstop.......

 

nice find... i actually just emailed DEZOD about that. curious to know what thats all about

 

pnp head makes a big difference, but not enough to compensate that much...i wonder where the rest of it is coming from

 

i was told that a P&P head on an N/A D17 will give you power loss

 

was there any "concept" pics of the 7thgen when it first came out?

 

are intake manifolds dont suck. the only problem they have is when it comes to boost..anything over 10 psi is a bit much for the manifold since its made of plastic. i think i might be wrong abou the 10 psi maybe its less than that. but the design of the actual manifold is fine...i dont think thatd be a problem if ur n/a... thats not wats causeing the gain they "predicted"....thats another thing.. they dont know for sure since it never went into production..

no they totally suck, along with being plastic the design is terrible. wish i could find the topic..boiler made a point about this awhile ago.

 

people run over 10 psi on the stock IM w/o problems.

 

just an idea... the K20A2 has a HP rating of around 160. If you put a high flow intake, an exhaust, and pnp, that would equal about 170 or 150 whp. Also, didn't the K20A2 come in the '02 Civic Si.

......so maybe, instead of a D17A2, there is a K20A2. Just a thought

...you couldn't be any more wrong.. like seriously wow.

K20a2 = HP Rated 201hp
K20a3 = HP Rated 160hp

'02-'05 Si came with the k20a3
'06+ came with the k20z3 (now drive by wire)

give me a fu**in break. i was trying to make a point, but yes, K20a3 was what I meant.

LOL, If you're going to pick on someone, like seriously wow, get your numbers right.

K20a2 = 200hp (02-04 RSX Type-S)
K20z1 = 210hp (05 RSX)
K20z1 = 201hp (06 RSX) After new SAE ratings took effect, same specific output, just measured differently.

 

I think I remember a long time ago that it had a k20a3, but i could be wrong. I wanna track this thing down.

 

people are dropping K20a3 in their cars for less than $2000.... imo K20a3 N/A build is much less and more reliable than Boost or K20a2.

o.O where did i state the z1, or the rsx/-s?

Didn't think so. If you really wanna argue about that 1hp in the k20a2, be my guest.

@ CivicInspired.

k20a3 more reliabile than k20a2 in a swap? What.... ? I think you mean cheapier.. and even than a thousand bucks or so IMO isn't worth the save i'd stick with a k20a2

Odds are you wont get it in there for $2,000. Especially with everything you need. When i was looking around for an engine i saw people just selling a longblock for $1500 so if you can get all those parts and install for $500 you're amazing. Plus i'd go K-pro so thats $1,000 there...

 

a thousand bucks save? wow... i would be doing it anyday!, its way more expensive than a thousand dollar difference, around here, just the k20a3 cost around 800 bucks, the k20a2 cost 3000 bucks

 

k20a or k20a2 is way more expensive than a k20a3. you could boost a k20a3 and be only slighty above the cost of a k20a motor swap.

 

this has been covered before. id like to see boilers post about why our IM suck.. i havnt seen it and i know boiler is reputable guy and knows what he's talking about. i just dont see why the design might be terrible. someone point it out to me or give me sumthing more to make me understand..

 

CivicInspired: did you ever find out anything from Dezod?

Paul has said the only thing that is holding up the IM's are materials.

I don't know why you guys would want one for N/A, since it's built for Forced Induction. You'll see no gains or you'll even see a loss, if you try and use it for N/A. If anything get some ITB's made.

 

Well, I see that conversations have been redirected towards K-swaps and such which is something that has been over-discussed.

The reason I wanted to post this article is because, again, I found it ironic that Honda said they could get 170hp (let's assume crank, which would mean around 150whp) out of the D17 with the following mods:

* Header
* 2" exhaust
* Muffler
* PnP Head
* High flow IM

I bet that the only thing that hasn't been tried on the D17 is the Intake Manifold, and it's because we don't have one available, and even then, from 127 to 170, that's a long trip for it to make such a difference.

Would you say Honda was bluffing?

thats why i suggested the fact that the motor could actually be a modded K20A3

they only way you could get those numbers out of a D17 is with some SERIOUS compression.

Dezod said that they could hit those numbers N/A but it would cost alot of money and some serious mods + a good tune.

Definatly not as cost effective as boosting

 

Gotcha, but I doubt it, because the article says they did these "significant engine enhancements" to the "1.7-liter engine".
