Hello to all d15 peps i have a d15z4 non-vtec an i want to get a little more power out of it nothing extravagant no boost.. jut some basic things that will make the car run faster looking for 30 to 60 bhp gain thanks in advance..

You can rebuild your engine and give it higher compression for 2000+ bucks or you can add some spray for about 300 bucks. Those are your only two options besides getting a different car

hi
I also have the same engine and i wanted to do a naturally aspirated build,are there aftermarket internals that i can use, i mean cam,pistons, rods, valvetrain etc,?

Yes there is check out this site http://www.bisimoto.net/store/ ,,,there is a lot of products there to do a n/a build

You dont need all these aftermarket parts to do a decent N/A build, most of the d motors have interchangable parts, all d's have 75mm bore so simply taking pistons from one to another can raise CR (example: d16A1 pistons in a D16A6 gives 10.7:1 CR) d cranks can survive close to 600hp , d rods will take 200hp, so for an N/A build i would just do the research and see what OEM internals u can use to reach your goals. then after your build you throw a good FPR, CAI, Header, and an exhaust, maybe a bigger cam and adj gear, nothin radical just a street grind. i dont think u will have any probs reaching your 30-60 bhp goals, and congrats to anyone doing a non vtec N/A build!!!! I'll help out anyway i can.

ive have added a CAI an a full exhaust 4-2-1 headers took out the cat getting a decent pull now just by gettin the car to breathe better.... next step i am plannin on doin is an ACT clutch an p plate,phearable non-vtec ecu,fuel pressure reg and msd ignition system external coil...is this good to do after the breathing part ors shud i just do a mini me swap..

I use an msd cap, rotor, and external coil, and am now runnin 58lbs W O T , so yea the msd setup worked well for me, where i was runnin real rich at 58, it leaned it out and has better throttle responce. if your going to change the clutch get a light weight flywheel , i run a 8lbs flywheel, a stage 3 6 puck clutch and presssure plate and i love it, but it takes some getting used too. as far as a mini me, research it and decide if it is worth doing to meet your goals

thanks man ill let u know how it runs after the upgrades ill dyno for results to...o an what is ur take on phearable ecu

I like the fact that they r cheaper than most, i had them do a zif and pm7 maps on a 91 PM6, was very pleased with them, had my ECU back in a week! there r alot of company's that u can use. I prefer Xenocron.

LMAO wow

LOL

Quick question am got the fuel pressure reg but stupidly forgot to check the psi of the stock reg what is a good set(psi) for my car... mods:CAI intake,full high flow exhaust.

i would start at 30 and slowly raise based on throttle response,if u get too rich it will bog down and blow smoke, stock 240,s can only handle around 70+ -(seen some run great at 75 and seen some fall on there face at 60), A/F gauge would help u out for tuning the fuel pressure, when u get it where u like pull the plugs 2 see if your gettin a good burn. i have gotten good results from msd setup and 1 heat range hotter plugs @58lbs. WOT but i run 11.5:1 C.R. and tuned timing, i dont care much for the stock coils. too really take advantage of the f.p.r u will need too beef up the ignition

i got the gauge i have the fuel pressure at 38 runs good i got a 700 crank bosh battery an awaiting the msd setup..

i dint get the msd i got nology hotwires they work great now to get the external coil

You should get it dyno'ed & tuned to see how far these mods have gotten you.

Just got it dyno'ed and tuned lastweekend making ( 143bhp) from stock (105bhp) non vtec motor stock internals no head work.
MODS:I/H/E, full exhaust without cat, y8 mani swap,fuel pressure regulator,nology hot wires,ngk plugs,stage1 competition clutch,XACT flywheel 8lbs ... happy now eeee check out d vid: http://www.youtube.com/watch?v=xnRkss4ogvc

damn that actually pulls pretty decent. good work! did u end up going with phearable for the ecu?

No dint end up getting the ecu so no ecu upgrades yet, i am still deciding on phearable or hondata s300... i just wanted to know if the s300 can work on my non vtec engine (d15z4) and where to buy it from and if possible there is a stand alone hondata already chipped and wired odb2 ecu

o and also anyone know if a d16y7 cam stage2 can work for a d15
