View Full Version : my little modifyed vtec honda city 650kg @ 130kw

well people its time i show off my little car, basically my car is a 1992 honda city import, and i got lucky to get the highest version available which has features like power windows/sunroof/steering/windows and not to mention being factory injected, but the real bummer is the factory engine, only rated at 50kw its weaker then the civic breeze engine, d13c vs d13b, however due to the weight compaired to a civic (1000kg+) the little engine flys, but i wanted to go faster to in the world of modifying cars, which i have modifyed heaps of hondas in the past, some of you might rememeber my vtec dual carb or some other crazy thing i thort up with in the past, anyhow i decided to put in a civic jdm d15b engine, rated at 100kw., twice the power of the factory 50kw, now if you think about it, a integra has 140kw give or take. thats 140kw @ 1200kg, and if im pushing 100kw @ 600kg thats like 200kw @ 1200kg, in other words this little car would blow the doors off a integra. anyhow, so i decided that i want to work this engine,so originally i installed it still using the factory d13c intake and exhaust to make things fit, but i found this way to restricktive, so i started off with a rebuild, and ordered some forged pistons from ebay america, getting the zc pm7/p29 would heavyly increase my compression, as sourced from dseries http://www.d-series.org/forums//showthread.php?t=21761 which explains the mods you can do to make your little sohc vtec make the same power as a b18c. yes that sounds crazy but not impossible. so i got head work done,and rased the compression ratio to 11.5 cr, not to mention getting some decent extractors, and modifying my intake manifold using the jdm vtec one, now comes the computer issues which im chipping and remapping the eprom, while using a datalogger made out of a nokia usb cable. http://forum.pgmfi.org/ my aim is to make a good 130kw out of this engine, and dont forget this, 130kw out of a sohc vs the b series, well we all know the b series is heavyer due to the dohc and block design, the bigest challenge was to fit the engine as its very close to the firewall and the rail, i had to smash out the sides alittle to make it fit, i think ive somed it up, enjoy.

lol, honda city turbo makes like 80kw, my d15b makes a standard 100kw, why would i want a turbo engine making less power with older technology?, besides if i wanted turbo i would of turbocharged my engine, some ppl in the d series website made 220whp on a d15b sohc vtec with turbo at 12psi, but by then im sure my gearbox won't hold up. ;) you have to remember when the city turbo was made, it was one of the first computers and turbo engines designed by honda.

power to weight maybe the same or better than "other" cars - but it dosent necessarily make your car "faster".
Take it to the track and give us some numbers to squabble over ! I want to see that thing run a mid 14 :)

Its a +15% increase in displacement increase WITHOUT full engineering etc

You can put a 60% increased displacement engine in your car if you wanted to legally.Its just time and money !

factory engine = d13c = 1.3l
vtec engine = d15b = 1.5l

i have not exceeded the engineering limit. also its 30% and not 15, i asked a engineer about a month ago when i had to register the car with this engine number, :cool:

Have you got an ET of finishing mate? How long are we going to have to wait to see this at the strip. Should fly and it will feel even faster than it is being so light.... If you get a full 130kw at the fly mate and can get traction it is going to be a weapon.

hey buddy
im loving ur litle project, honda city.
just wondering with the original engine was it fuel injected or a carbie.!?!
iv gota carbie and really wanted to do a mini-me vtec conversion as its more unique then the general b-series swap..
how much did u pik up the jdm d16 for..!?!..and did u have to change fuel lines etc. etc.
and i was reading u did a vtec carbie conversion..!?
please explain..ahaha..sounds itneresting..
and what internals did u buy and headers,zort system and all...im really interested...!!!
and was the pistons and stuff u bought of ebay any good...!?!...

well first your project, is it a honda city, cause the carby versions do not have a return line, which makes things difficult. also they use a electric fuel pump, if its injected your lucky. i know this cause i got two honda citys, one for spares. you can not do a mini-me vtec head conversion on this particular engine, as the d13c is not a d13b. its different. and alot is not compatible, one simple example is the bell patern. alignment to the gearbox. i had a d15b vtec which was in need of a rebuild from a civic. and i used it for the perfect conversion. the extractors i bought was very good ones, they have excellent flow charateristics when compaired to anything standard. with my civic (project before this) i did a dual carb vtec conversion as the original dual carb setup is almost as good as having a injected setup. gl/gli theres a 5hp difference. pistons from the zc rases the compression up to 11cr so thats a nice push in the d series area. theres alot more to do like tuning the ecu, but with alittle effort. things happen.

If u were in melb then i would have given u the box off my old EG GL engine for free (same as ED box).
Would be of better use in a project like this than my backyard.

verry nice
i hav been contemplating somethin similar (city/beat)+ vtec
but it seemed like a waste of time and its a tight cabin

so u used the d15, thats genius
comaring it to a b seres ud save heaps of weight and so steering would be saved too and power would be more than adeqate
get rid of the auto trans, its heavy and slow
and i think u should keep it N/A , makes more sence in a small car
no lag, better cornering control , less traction issues

wow ur project is cool, has it got jdm wheels??? would be so cool and an ef8 style rear wing would be awsome

love it

if u get sik of it then sell it to me !!!!,
that would make the sikest runaround
how much is it worth ???

hey if u dont need a certificate dose that mean a b18c in a ZC crx dosent need one either???

14-05-2007, 08:13 PM

i think sohc vtec is very enough for 650KG City
if use the Dohc vtec ,it will be too much power and hard the control that
just i think

crx_boy7
19-05-2007, 05:46 PM
the more power the beter IMO
however power = weight
and weight = bad cornering

manual is lighter than auto
keeping the weight down at the front is better for corners however frontal weight gives u less wheelspin in straight lines

MrJDMCivic
28-06-2007, 11:28 PM
ok, update. Just finished my car, got my self a city manual box as the ef crx box I had does not fit. Not even close. The d series engine is alot better than the b series for the following reasons, 1. lighter-no understeer. 2. Parts are cheaper to work/obtain (ebay usa has a shit load of aftermarkets) 3. It barely fits. Infact its hitting my dam firewall, gonna have to hit it out more. and 4. Im putting out more power than a b18c type r. lol but then again if you work your b series, you could also achieve more power. But that isn't what my post is about,.... to fit the manual box, I did a shitload of mods. Every two minutes I was kicking my self saying why doesn’t this fit!. and where’s the grinder. Example, I got my self a nice y8 block, it had a alloy sump, looks nice and I prefer to use alloy due to the fact that tin sumps when lifted from the bottom block the oil pickup. However the alloy hit the cv joint, so it had to go. Back to the tin sump, which worked great.

Right now im running the engine without vtec or tuning, and its already getting wheel spin., this is going to be interesting.

Mods.

head been ported and polished, 3 angle seat job, cam s3 crower*,cam gear, aftermarket valve springs (allows more push down) b18c throttle body, pm7 pistons, higher comp 11.5:1, extractors, crome ecu, basically your nice and mean vtec engine,

Already the car is dam quick, :)

http://www.tnttec.net/beat/beatcity.JPG

sorry people, i hav'nt had the time to update my little city page, but ive decided to get out of the game, and sell my little beast, so if anyone is interested, let me know,

it is the highest model honda city with power everything (most citys dont have electric sunroof or power windows.

honda city ga2 1990.
power windows/sunroof/steering/mirrors/aircon
full twoway alarm with remote boot opening, automatic remote put up windows.
touch button boot and fuel release.
mp3 pioneer deck ($1000 deck-when new).
new mags with new tyres fitted
almost full year rego.
mirror tints (600 alone)
------
engine is a d16y8 (2000 model coupe block)
zc pistons 11:5.1 cr
jdm vtec head, aftermarket stage three valves, alot of porting, moding head/block/pistons/gaskets etc
intake is b18c manifold/throttle
adjustable cam gear
extractors
p72 ecu with crome (programmable to whatever you want)
new box/clutch/cv's
(car has driven 3400 kms since new build.)

makes approx 140kw @ 650kg

so dam fast nothing keeps up. just in first you smash most cars, cause of weight and no bogging.
leaves type r's integras/civics/legends/s2000's for dead.


alot of other mods as well, just can't think right now.

the manifold is the d15b vtec version which is been ported out on the intake and the throttle body side, the throttle body is a b18c throttle body, if you look at this picture you can see the b18c throttle body is alot bigger than the d15 jdm intake, even thow ive ported it out. the reason behind using the b18 throttle is that is where the biggest intake restriction is.

also the rear drum brakes work great, so people should never diss them, heavy trucks which weigh over 5000kg use drum brakes to stop., and we are talking the front brakes. besides that the biggest issue with any stock brake setup is the overheating on constant braking. and what makes things worse is if the car is heavier, example, my honda legend will generate more heat and more warping on its brakes due to the weight and braking of the car, but since the honda city ga2 is almost like a motor bike, brakes rarly get hot.... remember some of the fastest bikes weight between 200kg to 400kg. i mean a extra 250kg and your at my car. understand now? - ppl that flood my sale forum without any true understanding or logic. enjoy your answers.,
