ok, i have a 2005 LX, its mostly stock (engine) since i knew one day i was gonna swap the motor. ive read the stickies around, but normally most are about the RSX-S 2.0 I-vtec or the 2.4 from the CRV and accords... where i live, i know about 4 guys who have a civic, but the 6th gen but one of them have a ZC (not sure if thats the right way to spell it) engine, and its turboed and nitroed. i know he has invested a lot of money, but he tops his car at a 155 MPH and thats because he rans out of street to continue. i want my engine to at least get to 350 Wheel HP (without nitrous) cuz im tired of seeing STi kick my *** lol. anyway im getting 10k from an heritage and prob can get some more later to continue my work. now the question: can the RSX-s motor top 350hp or more? or is there a better engine, even if its expensier, but that can put on more HP? because i know that not always the biggest motor is the best one. Example: the VW GTI vr6. people where i live trade the vr6 for the 1.8 turbo and ive seen the 1.8 racing the vr6 and they kick their asses. plus with the vr6, the weight ratio of the car is catastrophic. so anyway i want a motor that can be made (if its not already) DOHC Vtec Turboed and made internals and everything custom/mod that can reach at least 350HP. i would love 400, but lets be real... any suggestions? thanks

k20 from type-s

hmm, why from the type S which is the k20 a2 and not the one from the type r which is the k20 a? i believe the k20 a comes with a 6 speed transmission, which i would love to have. still not sure on which one of those 2... i was browsing the hmotorsonline.com page looking for different motors and those 2 from RSX sound nice, but what are the diference between them and which one can you get the most HP from?

There are many differences between the k20a and k20a2. Off the top of my head/cams/intake manifold/gearing/CP ratio/and I think exhaust manifold are all different. A boosted K-series can make 350-400whp. I don't know how hard it is to make those numbers but it has been done before. Check out K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum there is tons of info there.

k24 with a type-s head with a GT30R will get you there and then some!

you can build a monster K24-k20 head engine that will be a complete sleeper, now you add some minor boost and Kpro and it starts to get real sneaky

a2 is more turbo friendly than a

just some personal experience, 350 whp is a butload of power. Most people dont realize how much power that is. That aside, if you want 350 safe and realiable whp you gotta build the engine, new rods, iron sleeved, pistons etc. Then you gotta decide wether you want a standalone or piggy back engine managment system. I herd hondatas pritty good I used SimpleDigitalSystmes Em-4 which is extremely easy to use and had a decent base map to work from. I'm guessing that you don't have much experience tuning so your going to spend some serious cash on dyno time. Basically make sure you know what your getting into or you will waste tons of money and end up with a POS

k20a2

andyman did it with the vtec d17 fully built engine for a whole cheaper than an engine swap. AND BELIEVE ME i have seen it a couple of times in person, looked under the hood, heard that sweet BOV and heard that exhaust gas run through that muffler. Seeing his car will make anyone second guess a swap

by any chance you know how much wheel HP that car with the d17 is pulling? is it DOHC or SOHC? because i was thinking about a swap for higher HP and the motor wont be so "stressed" since the k20 is bigger and a bit stronger. anyway thanks for all your info, ill be trying to look around for the k20 a2 where i live. that motor comes with the 6-speed tranny right?

 
Rep Power: 336

it will mate to 6 speed...good luck on your quest for power.

andyman i think is makin 335HP and 255 tq at 18 psi...atleast thats what his profile says and hes runnin a Dezod turbo kit.. on stock sleeves

 
Rep Power: 0

wow 335 hp with the d17 SOHC really does make you second think about a swap. by any chance is there a 6-speed transmission for the d17? because ive looked around, but never found any... well thanks for info again !

If you want 350whp from a K20 it cost too much plus you have to go turbo....you could just fully built your D17 and turbo it and get as much horse and less cheaper...

i doubt what andyman did was less than a swap, dezods regular kit plus all that stuff u need + install(if you cant yourself) is close to what it costs for a k20 swap and that turbo setup would be putting out under 200hp not 335 or w/e andys is.

I donno if Andyman has dyno sheets, but 335 hp with a Dezod Kit? Im not knocking the kit at all, but thats like a 300% increase over stock. I would like to know what other mods he has.

 
Rep Power: 303

go research it yourself. dont expect other people to provide you all the info. its all posted here

I took your advise; Andyman definately knows what hes is doing and a but load of work went into his vic. I also checked out some of dezods posts and I saw that somebody with his kit is pushing 400 hp and also has a fully built engine, alot of dyno time etc.

right now, i found a k20a2 with a 6speed tranny for 3300 where i live, plus taxes (its 5.5% here) but seeing you all saying that with the d17 reaching the 400hp really makes someone think twice about the swap or stay... i havent still made up my mind sicne the last posts ive seen here. umm some quick questions: is it hard to make the normal d17 to a vtec DOHC? is there a 6 speed tranny for the d17? ive never seen any. thanks

Wow, I cannot believe some of the posts in here... lol. I can GUARENTEE you that everything Andyman bought, at a price available to YOU, would be more then a swap. Not saying there's a problem with that. Also, the D17 is going to max out WAYYYYYYYY before an k series does. It's just a fact of life.

 
Rep Power: 297

agree...

you can only max out a d17 motor in your car so much before it tops out..

heres an example.. you can get a k20a2 (STOCK) boosted with 12lbs and already be getting 300hp+ of power to the wheels and still be daily driven

you can also take a STOCK k24 block and put on a k20 head on it and boost it around 12lbs or so and guess what.. you'll be pushing 400hp+ of power to the wheels...

now take this scenario.. STOCK for STOCK... your starting HP for a D17 is around 110hp.. give or take a few depends on which motor you have..

a stock K20a2 put out 200hp give or take a few... the swap alone gives you 100hp more into your car and its STOCK... put on some headers.. intake.. kpro and tune it and you could push closer to 220hp or so... and thats ALL MOTOR...

for a D17 to even push the same amount of power a k20 does you need to boost it.. if you want to push anymore power out of the little D17 motors in our cars your gonna have to fully build it so it can handle the higher boost.. and in the process you might even loose the ability to daily drive it..

just some FYI and something for you to think about
