all right...ive got a 2000 Honda Civic EX right now with a D16y8 in it...the only mods i have on it right now are a AEM Short Ram Intake, Megan Racing Muffler, MSD Super Conductor 8.5mm Plug Wires, NGK G-Power Plugs, Weapon R Strut Tower Brack, Summit Cross-Drilled/Slotted rotors, EBC Greenstuff Pads, and i have my timing advanced to 30'. I was Just curious what my next step should be...im looking to stay all motor with this build, so i dont know if i should do a header next or if i should do an intake manifold or a cam or what...so common fellow builders...GIMME SOME INPUT!!!!!

 

wait 30 degrees?

 

d motors dont gain much HP unless u boost,

 

thats what the gun said...cause factory spec on it was 25...and maxed was 30, and that was without damaging it...

 

mm no stock is 12-16 degrees so i would fix it if i was you.

 

hmmmm...well, what exactly is it hurting if i leave it where its at??my gas mileage or my motor?

 

How is your car JDM like your name implies?

 

its on its way to being jdm, but for your information, this isnt a hate forum, its a help forum, so if u have no imput...find another forum

 

and its actually got jdm sidemarkers on it...and the foglights and CTR headlights arent pictured yet

 

you will bend a valve or damage a piston, and having headlight doesnt make you jdm

 

i didnt say it did make my jdm...i said the car is on its way...

 

You're not going to make any sufficient power going N/A with your y8. You're best off buying a Greddy/Edelbrock turbo kit since both of them are CARB legal, I believe. But other than boost, the only thing you can do to make more power is to swap out your y8 for something else.

 

Just wondering since you have a "JDM EK"

 

Header +5hp

 

For a SOHC, boost is the only real way to gain for a lower price, unless you have plenty of money and desire a all-motor project. If your wanting to stay all-motor and make power cheaply, you'll be best with a b-series swap and go from there.

Pretty sure he means ignition timing...didn't see anything about adjustable cam gears.

Ignition timing that far off is bad for the engine overall, most likely much worse mpg due to poor burning of the AF mixture, loss of power, added engine heat, added stress on engine internals, etc.

If you have those plugs fire too soon you're going to be pushing the pistons back down when they are trying to come up...(if it ignites)

 

Get a header and a nice flowing exhaust. Maybe hook it up with a more aggressive cam or something. There are tons of things you can do, but unfortunately they aren't going to do much to a D-series.

You'll get the most performance gains if you stick to suspension work--front/rear sway bars, front/rear strut bars, a nice coilover setup, etc.

If you're not interested in suspension stuff (i.e. you only want to go fast in a straight line), either turbo the D16 or just go for a B series.

 

i was reading in hondatuning that they have a forum call immortal D. and it calls for just a shitload of head work and a tad bit of bottom end work...and it'll be mashin on duals no problem...but i dont know...im just looking on some input on what to do...ive heard i can put some ZC pistons in my Y8 and theyll swap right in...is that true?? and i have a little bit of suspension work...i have a matrix fully adjustable kit and a weapon r strut tower brace...

everything being stock, with pm7s/p29s, you're gonna have hella compression. more agressive cam will help with lowering your compression due to the valves being open for more degrees of duration, causing compression blowoff. pm7s out ot the jdm dohc zc or the 1st gen usdm integras (p29s) i believe are the same... same diameter (of course 75 mm), same pin hieg. get some shot-peened ls rods, different rod bolts, have the pin end re-bushed for the d series pistons, and the big end shaved for the d series crank journals... plus alot of other things....

 

i think that a SOHC wont necessarily mash on a DOHC because it has a lot of head work and some bottom end work... maybe a stock B16, and a fully built D16, but for the most part.. B series is where its at unless you boost that D

 

your best bet is swapping in a DOHC, unfortunately SOHC's don't respond too well to bolt-on's, if u wanna keep you SOHC your gonna have to spend some serious serious cash.

It'd have to be a pretty unfair competition. My buddy's 89 Si had a rebuilt D16A6, and that car had equal, if not better acceleration than my 2000 Si with its original (stock) B16A2. Keep in mind that the EM1 is also several hundred pounds heavier.

 

You are not going to get a lot of power out of that Y8 unless you really build the motor from top to bottom. If you want to make the car a little more fun to drive I would suggest installing a light flywheel. You will see more results with the light flywheel then you will with all the other "junk" you installed already.

I should have been more clear.. i meant if the motors were both in a similar car *like both EG* then i think that the B16 would beat the D

It's cool man, I was reinforcing your point. A stock B16 still has more horsepower than a D unless you have some serious business going on in there, plus DOHC VTEC will destroy its SOHC counterpart. My point was, the only way the D is going to beat the B is when there is some sort of unfair playing field.
