i have a 1998 civic ex with a d15b vtec. i have a dc sport header,aem short ram intake,skunk 2 intake manafold,thermal exhaust,apexi v-afc. i have no idea y my car is super slow. i have basic mods. i know that it is only a 1.5 liter 5speed but y am i only running at the fastest a 16.7. and i know how to shift i also have a short shifter. no matter what i do i cant get the answers on how a stock 4 speed d15 NON VTEC can run as fast as me. wat should i do until i can aford my gsr motor. does anybody think i should run faster than i am or is a 16.7 about right for the d15b withh all those mods. please help me i no im not the smartest person about the motor

 

ok.. you have to think about it this way.. what happends when you run down the road.. everything is equal.. now what you did was run down the road with a olympic guys legs, and upper body but you still have that fat guys stomach.
to actually see the motor work you need to free up some air flow in the head, so basically just wait for the gsr and put all your money in that.. unless you want to get better cam,valves, springs, pistons,rods, **** like that.. no matter how big of a exhaust, intake you have the heart of the motor is still stock so it can only take so much.. next best thing is forced induction to force the air into the combustion chamber.

 

I know a guy that has a crappy mini me and it ran a 15.8 then he had me put a del sol vtec trans in it and a stage 2 clutch and a $288 cam and he only ran a 15.7 after all that crap.

 

remove ur manifolds and clean the [freak] out of them with abs safe brake cleaner head to toe even injecters to there can be build up that robs power also run some seafome in the motor ir or the alternative urs varsol in the cam cover dont rev tho let it idel for 5 min then turn off drain oil and change filter it will get the slug off the walls and cam cover if dont right it will make a big diffrence trust me also injecter cleaning whould be good to not the stuff u usein ur tank the real way lol take them to a shop and ur motor will run as good as new also if the car that u ran up aganst had a si tranny the ex tranny is alonger ratio so u are in 2 he is in 3

 

so in the end getting the gsr would b better. i already used cfoam in my car and i ran octane booster. i will try to clean the manafolds,but does anyone know what i would all need to drop in the gsr. i no i need the ecu,tranie,and motor mounts and stuff. but what is involved in a complete swap. and import wars 2 is may 25th at great lakes dragaway wisconsin. is there any quick mod or something that is cheap that i could do to get my d15 running better thanks for the help

 

Maybe ur motor is toast. I run more than a whole second faster than that.

 

if you're running a stock engine, don't use octane booster, it doesn't help you at all. the higher the octane rating of fuel, the more RESISTANT it is to burning. this is good if you're trying to avoid detonation, but unless you're running high compression, boost, or a big timing advance, you're not helping. (i've actually seen several studies on modern cars where they dyno'd more power on 87 oct. than on 93 oct.)

don't take this as hating, because that's not how i mean this: your car is super slow because you haven't done any modifications that really make it faster, only louder. i would bet dollars to donuts that a chipped ecu and good tune would do more to help you out than all of those bolt-ons with your stock computer. i'm with the guy above. you probably at least need a cam (and preferably a chipped ecu and tune) in order to start seeing gains from your setup.

also, you might check your compression and make sure your engine is still good. i don't know how many miles you have on it but if you don't have good compression you're fighting a losing battle.

 

Wrong forum. This should be in the 92-00 forum or all motor.

Just a suggestion.

 

i only have 60k on the motor. i do not want to buy cams or chip my ecu because i am saving up for a gsr i am buying. i was just wondering if there werew any quickcheap and easy way to gain a lil hp. my car runs fine so i do not think it is toast the vtec kicks in good and runs chrisp. so should i just try and get it tuned. dont worie i do not take any of teh comments to offense bc i know myself that it is slow. i was just wondering if its just my d15 that runs this slow or is it most d15 with not very much done to them. SO SHOULD I PAY THE $150 an HOUR TO GET MY CAR TUNED OR JUST WAIT AND GET THE GSR. thanks for the help

 

get the gsr. d series in an ek is pointless imo unless its boosted.

 

boost the d man.

 

but dont u think it would b better to get the gsr motor than spend the money turboing the d15. cuz if i am going to turbo something its going to be done right withh all trhe necessary parts and professionally done. what is everyone opinion DO I GET THE GSR, OR SOMETHING ELSE

 

I guess if you have someone else Install the TUrbo, then yeah maybe expensive, but if you do it yourself the Turbo D will be cheaper and more powerfull. I personally would go Turbo D, especially sincie D's are cheaper and if something goes wrng, Tada another d for 300 bux. IM done here.

 

Do a compression test..

 

for simplicity and reliability, i'd go w/ a stock gsr swap over a turbo d, but if you build it right and get it tuned, a turbo d should not give you problems. either way, it's really just a matter of what you want.

 

first off, wrong forum
when i swapped a z6 into my 89 hatch w/ intake,header,exhaust, i ran against the same car as me ( 91 si with the same stuff as me ) i got him in firtst gear but after second i couldn't catch up. later on with futher research, i found out that my timing jumped a tooth. so after i adjusted my timing, i ran my friend again but this time i was the one ahead..
so check your timing&compression, if your timing is off, adjust it. if compression is all messed up, then use your car as a DD and save up for a b-series. goodluck to you

 

i know i am in thw wrong forum. but i am getting a gsr and trans and ecu for 1300. and wouldnt it b cheaper to buy that then to turbo the d.

 

Dude if you're questioning the D so much, just Go be a B series fan boy and ejaculate on dual cams

 

Boost it!

Im working on boosting my d15b non vtec right now... hopefully be boosted in about a month.

 

y wouldnt i questoion the D. im only running a 16.7. the only question i rerally care about is am i gona run faster with a boosted D or am i gona run faster with a all mnotor gsr with basic parts like intake and manafold headers exhaust cam gears and stuff like that. if anyone wants to but this motor i will gladly sell it because i do not think i wish to run any kind of forced induction just yet so its up for grabs if anyone hapens to want it
