mods

[redex04]

i was wondering, what r some mods that i can do? i have a D17A2, and i would like to do some things to incrase my performance. would it be possible to do a regrind to my cam or anything thing at all. i am just trying to improve my car in some way other than suspension. thanks for any suggestions or comments that you can give me.

[Jdm_4_life 1234]

TURBO IT y0!!!!!!!!!!!!!!!!!!!!lol yeah boost it up!

[BiggyQ]

There are actually a couple ways you can increase your performace. Obviously you can turbo the engine. For the head get some aftermarket cams by crower and get some valve and springs to balance out all the improvements.

[berettagtz117]

Not much.. There is no aftermarket support for this motor.. I know because i own one. I have had mine for over 3 years and still nothing does anything for motor.. Turbo is no good for motor, it has returnless fuel system :( It cost alot of money and you get minimal gains plus the motor dont like it very well.. N20 is about the best bang for buck if you want more power, they can take a 55 shot pretty well but there not all that strong @ all..

[BiggyQ]

There is actually some support for this engine. It isn't major support like the K or B series engines, but there is still some support coming from companies. A good example is dezod.

[redex04]

so when u say the motor wont respond well to the mods i might make, what do u mean by this? im currious about this, cuz i would like to make some extra power to mess around with.

[MyblkVTEC]

intake, header, exhaust???? maybe

[redex04]

i am seriously looking into get a header, but i want to know that i will have good results from doing it. please let me know what u think or guys who have made the mod b4 on a D17, plase let me know ur results? i would love to hear in thoughts or advice. thanks.

[redex04]

its the header that dragman99 is selling. what do u guys think?

[Richie_A_19]

will the d16 shit fit the d17??

[berettagtz117]

I have 02Ex and I did I/H/E testpipe and I lossed power.. The DC header is the biggest waste of money out of all of them, it is actually smaller than OEM header :( here is my car www.cardomain.com/id/berettagtz117
If you want to go faster w/ this car the cheapest way like i said is N20.. If you want to perk the engine bay to make it look nicer and "SOUND" faster get intake/exhaust.. Otherwise its really not worth all that money..

Hey this is what I would do, get a nice AEM or DC intake, get a nice catback exhaust and fine a nice Nitrous kit, remember tuning is your friend in the world of modication to motors....... and remember to get colder plugs..... good luck!

[speedfoos]

I've got an 03 EX with the D17A2 and most everyone is right, you won't get a lot of gains from most of the stuff out there. However, (pause for effect), a couple things I have done is CA intake (Ebay special) and exhaust (N1 stealth from Nopi) and I have a header but just haven't installed it yet. The reason for that is the stock header is decently designed, IF you go in and do a poor man's port job on it. There is a lot of spatter from the production welds in there that dork up the airflow. These mods have made a little bit of difference that I can tell with the butt dyno. Best advice is to start your mods with a plan in mind. If you want to eventually try a turbo setup, build your motor up on the naturally aspirated side first. That way you still get the gains as you bolt-on parts, you don't waste money on parts you won't use on a turbo setup (like a header), and plus you get a good feel wrenching on your car. The most important part is that its easier to get good boost gains on 150-160 bhp modded NA engine than on a 127 bhp stocker. Check out dezodmotorsports.com for some cam options too.

[redex04]

so would a cam regrind be a waste? or would it be a decent one that i could still add stuff on later?

[redex04]

what a drag i read a post about cam regrinds and i cant get it done for my D17. it kinda bites to have gotten a honda to do mods but its not worth doing mods for......ohhhh well....i guess i will have to plan on buying something i can mod in the future

[custom_junky]

the d17 motors in general are about the worst motor the honda has ever made...i have tossed about 500 dollars in repairs into this motor and STILL can't get it to run like it used to (by this i mean like it did 3 MONTHS AGO!!!)...what originally started all this, is that the car over heated on the high way because the water pump failed...you over heat these engines just once, and all hell starts to break loose...right now i'm considerin a trade in...the trade in value of it is 5,000 dollars....i could just go out and get a 95 civic and get some cash with it too....hmmmm....

[berettagtz117]

^^ Yea that happen to my friend, he broke ringlands when his overheated, the gasket went and all..

[custom_junky]

well shit, i think i will DEFINITELY get ride of this damn car this week then...a honda dealership has offered 5000 for trade in...maybe i can pawn it for that and go by a car for cheap and with cash left over...hmmmm...

[Rexinre]

Wow, I didn't know they were such crap motors... damn.

drop in the K motor for the win!!!!

[redex04]

ur saying the trade value for my engin is $5000 or 4 ur car?

[custom_junky]

red - that is MY car...which is a 01 ex four door with 100,000 miles on it...and it is concidered fair condition...meaning it has cosmetic blemishes, possible rust, and interior issues...however has no mechanical defects...

[redex04]

thats what i thought, srry for the stupid question

[ottomaticjack]

Yeah, the wife's 02 is an increasing pain in the ass. I've been driving it on and off for work (courier) and have put some miles on it, and since I've been driving it, we've had to replace the trunk latch, the inside tie rod ends are going bad, aside from the fact that the body is so flimsy as to be scary. I was working on the trunk and bent the inner supports by accident...I could feel it flex in my hand....now it acts like it needs plugs again..(changed about 6 months ago) and of course they're platinum....just about the most cheaply made civic I've seen....<sigh>

[redex04]

that suxs man.....im still pissed that there are pretty much no mods i can do to it that i want to do.......but ohhh well im just gonna plan on going all out on a hatch in the future.

[02civic]

u could go with a clutch and light wheight flywheel and get about 20 horse from it and pulleys aem.hks makes a turbo manifold for the d17 also.overboost.com

[redex04]

cool man, thanks for the tip....i am always looking into doing something/fininding something new. i had considered doing the clutch and flywheel, and u said AEM makes the pullies for a d17?

[02civic]

skunk 2 makes a throtle body for the d17

[flip1405]

if you register at 7thgencivic.com there's a couple of people that has made some decent power out of our crappy engine. supermex (on7thgencivic.com) has made over 300whp but spent alot of money on it. you can make some decent gains with the d17 but have to spend alot of money on it!!! also he turbo'd it!

[redex04]

well guys i am now interested in auto crossing my car! i want to compeate in stock class to start with and move my way up. well it says u can have an exaust from the catalytic converter back and i was wondering if i could put a RSR Mag on my car like that? i dont really want a huge exaust just something kinda small and sporty that sounds agressive and maybe give me a little extra power! thanks for your help once again, i am always willing to listen to ideas/suggestions u have!

[custom_junky]

if cat backs are legal then i would say yes, the RSR Mag is a cat back system...good luck with auto crossing!!

[redex04]

thanks i have been compeating in a frieds BMW 328 and he has been helping me convince my parents to let me start raceing in my car. so im gonna start auto xing in my car, in the stock class with street tires. rules say u can have a air filter(i have a K&N) and u can have a cat back exaust. so i am gonna work on geting every advantage i can have.

[b00stedSohc]

rsr ex mag ftw! very good sounding exhaust. my friend has one on his 02 rsx-s and it sounds great.

[D16A6T]

d17 is hard to tune due to the new obd2a3 system.

[dkid15]

what u should do is make ur own arc box w/ sri and a y8 mani and u might make 10-15 whp. YOu will make great top end on the new im because it is due to the shortened runners. YOu could pnp and go crower. U would maybe dyno at 135 tuned. Depending on the extent.

[blackDseries]

were kinda being teased in a way , lol , a K swap will bolt right in with very few mods but of course cost big bucks still. these cars will be like 95 civics some day when K series get cheaper , everyone will want a 7th gen civic for a K20 swap just like everyone wants a 5th with a C1 swap now. the D17 aint all that bad , i toasted a 96 civic hatch with a DOHC B18B1 swap in it running hondata. just with bolt ons , OBX full stainless race header , ram intake , borla exhaust. lowered 2" with 17" BSA 296's. as far as returnless fuel system thats fuk all man easy fix. im gonna play with boost a little for a couple years till K swaps get cheaper and away we go. bring your B series shit on. lol.

[gmcuajo]

And what do think about the PMS pistons? Those pistons are in the 01-03 civic GX (natural gas powered). The PMS's are high compressions (some 12:1) and fit the D17A1-A2. Have the same compression height and dimensions (exept for the dome).

I think higher compression with a Y8 manifold, crower cam can make some power out of this tired motor.

[blackDseries]

well it sounds like you want to build an N/A engine. if thats the case than stroke it out and fire cams in it. as far as PMS pistons ive never heard of em , but 12:1 ratio is a high one , real high. and can they handle the abuse since there designed for natural gas? also crower doesnt make a cam for our car , noone does , i been looking into the idea of getting one custom ground. its possible i know for sure but exspense is somin i dont know yet. not cheap for sure. i wanna look at scematics and see if a Y8 valvetrain can bolt into our A2 head. or W8 whichever. as these cars run actual VTEC.

[dkid15]

actually crower does make a cam for the d17a1 but not the d17a2. YOu have to go to delta for a regrind. I hear the d16 manifold swap isnt that hard either. YOur really trying to copy whats on the d16 manifold. I do hear it takes time though. Correct me if im wrong.

[gmcuajo]

and can they handle the abuse since there designed for natural gas?

I heard that engines have a stronger connecting rods, but the pistons should be the same as in any d17...

[gmcuajo]

actually crower does make a cam for the d17a1 but not the d17a2

Crower make about three different camshafts for the d17a2 VTEC engine.

[gmcuajo]

i wanna look at scematics and see if a Y8 valvetrain can bolt into our A2 head. or W8 whichever. as these cars run actual VTEC.

I never try or heard about, but I think the y8 valve train doesn't fit in the d17 valve train. The y8 have the common VTEC with three cams and rocker arms. Actually the d17 is a VTEC-E and have only 2 cams and rocker arms.

Exept for the VTEC-E, I think the d17 valve train isn't that bad. It's vtec rocker arms and the exhaust rockers are roller that reduce the friction loses. That VTEC-E can be solved by a crower cam and a VAFC.

Edit... Y8 valve train will not fit the d17 head.

Are you 100% on the d17's being vtec-e?

[Rexinre]

Edit... never mind

[gmcuajo]

ok;)

[gmcuajo]

yes, all the 7th gen civics are vtec-e, also the K20 si

[blackDseries]

no DOHC engine is VTEC-E dude. K series engines are DOHC VTEC. I-VTEC to be more specific.

[jimmyb34]

the ep3 si k20a3 isnt advertised as vtec e but thats basically what it is.. both cams arent vtec... just one

[blackDseries]

yeah true , i always forget about that engine , lol. what a sham eh , a VTEC E dohc engine. but both cams do have VTEC , just no middle rocker like real VTEC. works the same as a D17A2 cam , just 2 of em.

[Rexinre]

My comment is... If an aftermarket company made a cam for the Y5 it could be crazy! Roller rockers FTW.

[gmcuajo]

About what Y5? Its a 7th gen forum...

[Rexinre]

Just saying there slick. They already make cam's for the 7th gen shit.

yes the D17 valvetrain is a good design , for longevity and fuel efficiency. but not for going fast or making faster. VTEC-E cant be solved by anything except trading your car for one with real VTEC or performance VTEC. even if you put a cam in a D17A2 , at the end of the day , its still a VTEC-E engine.

[andre_p]

i think it's good to raise the comp. ratio by swapping the pistons with D16's or D15's..

[gmcuajo]

Do you know someone who did this or plan to do? What you think to do with the compression height? The d17 have a 27mm compression height and must of the d15 and d16 have 29-30mm.

[SLO SOHC]

I do not care for these cars at all and I work for honda!
Good luck modding it... The idea about putting d16 pistons in sounds quite interesting tho!

Someone needs to find an easy way to make the fuel system work, then all problems will be solved! Isnt the new turboed acura returnless also? I havent seen much on that platform yet?

Be sure to get your headlight switch fixed... Oh how many of your cars have blown front struts?

[blackDseries]

mines lowered 2" and no problems yet. common problem is it i assume?

[Jdm_4_life 1234]

you will in the long run with the struts

i am a owner of a 2004 and was curious to the problems with the headlight switch and the struts?????

[gmcuajo]

maybe you don't feel it when driving, but take it out, compress with hands and see how fast they go up. Then do the same with a new one (of the same or older model) or a KYB, do a conclusion.

[custom_junky]

i use to own one...then i traded "up" for a 98 :)

[k1dfreeze]

you should buy a vafc2...i think i have one in my room for sale right now lol
