Lets Talk d-series

[B147ch]

It a pretty simple formula. Out Y1 is eqiv to a Z6. Y7 = Y4, Y8 = Y8. All the DOHCs are the same.

D's dont make 80kw without internal/cam change. All these mods ive seen dsicussed here;

headers
exhaust
intakes
leads

All they do is add bling and noise. You need an ECU to take advanatge of any of thee mods. Then the aim of the gain is to increase timing, lean it out a bit and tune it for 98+ron. But you arnt even going to make that much more power...

D-series NA is really really hard to do cheap on a budget without technical skills. First thing i would be doing is camshaft (zex 59300), ecu and cutting the bottom out of the airbox/SRI. With these mods, u will prolly pickup 10-15kw and the car will still sound/look stock. Maybe add a catback exhaust (2.25), but its going to add more noise then power.

From the discussion above re header types, its clearly evident that the OEM cast manifolds are basically as good as you will get.

just the person i'd like to talk to...

that's my dyno up there, and i've got a before and after mod dyno sheet.. 109HP atw isnt possible without cam change?
the before dynoe'd in at 96HP atw..

either there was some cam work before i purchased my car or i'm just fukken dumb (dont quote plz!)

anywhoo.. do you think the whale penis is worth looking into??
Cos like i said i have the stock airbox and pipe - just replaced with K&N panel filter..

Also what ECU is worth looking into to take advantage of these mods??

s'all good..

see my old dyno? :P

need to see what its pulling now since i've slapped the headers on lol

Yeah man,do U know why the wonky line? Just curious as to why it's like that...

LOL it was snapped on my phone camera..

i can show u my plates on my car to match the dyno if you are that concerned!! :P

[beeza]

Nah man,I don't mean like that...I just meant it's not a smooth curve as such.I'm just learning how to read Dyno graphs so I was just wondering how you can make the line smooth. i.e.looks like the car needs something to get that curve smoother.

hmmm...

What do u reckon it needs??

ideas are welcome!!

[beeza]

haha,dunno! anyone got any ideas?

Screw zex camshafts, i read up on d series.org that its shithouse!

theyre all recommending the Crower camshafts. they have a nice range from stock to full race.

for all you d16y1 boys, here's a product that should make you jizz in ya pants!

your curve seems rather lumpy...
could be a lot of things. easy things to check would be ignition (leads, plugs, timing), fuel system (any blockages - partial or full - messing with the fuel flow?), and last thing would be the ecu tune. seems like it could be feeding in diff levels of fuel at diff intervals.

crower cams are good, but if you're only looking for a regrind, send your cam over to bisimoto for a level 2.2 regrind (best duration and lift you can get from a regrind, especially if you cant afford a hard weld)

[B147ch]

thanks for that.

the other think i was thinking is that my apexi vtec and air flow controller may need to be adjusted also..?

[yuentinlon]

SO.... for my eg civic

i changed K & N pod filter

4-2-1 header

leads

and exedy 7lb light flywheel and whole clutch kit set



now... i am looking for a fuel computer like VTEC control or something

but what will be the price for install that one and tune that basically ?


i see that stage one cam already... but isnt it need a ECU tuning ?

Don't touch the VTec crossover point.

Honda has it set where is should be even after mods..

Adrian from TODA played with mine on the dyno a few weeks ago and we found that stock point was the best point..

You will however get some gains for a new ECU and tuning but I doubt they would be noticeable

OK >.< thanks for that ... so is time to save some more for my D turbo , haha
