boosting a D15b

[sPoOnD_]

hey guys, im about to get D15b engine and a Greddy turbo kit..but i wana noe if i can run stock boost witout touching anything else...im not gona boost it up at all...just wanna get my engine put in and turbo kit in..

[2MPRSS]

why a d15 but? thats my first question

[EGB18CT]

save ur dosh and put in a b18 instead prob work out the same cost as a d15 and turbo and will have the same power (prolly be quicker too as its na power band)

[sPoOnD_]

jdm d15b..nah, b18 not for me ey..outta my budget..

JDM d15b Installed $1600 turbo kit $2500 installed

[Weq]

yes, it will be fine.

/close thread

the amount ure spending you could drop in a b16a installed. or even buy a b18c cut and install your self. dont bother turbo this D series motor, just becomes waste

Dnt forgot u will also get teh DOHC vtec SCREAM. Mannn, nothing beats the feeling of hitting 5k, swapping over lobes, and watching the needle screeeeeeem to redline. Only women shift at 6800rpm.

[hisoka]

ohh nah dunno about that~DOHC vtec scream noise < Turbo compressor surge noise lol.

DOHC VTEC makes petite girls wet. While turbos make the fatty's churn.

Petite > fatty.

[chauster]

Scream? B16B?


Godzilla Bitch

[Sexc86]

hahahah john!

[sPoOnD_]

so it shld b fine yeh?..130hp at the engine for the JDM d15b..wat u guys rkn it will make with turbo kit?

a boosted DOHC makes no noise, it actually goes quieter than under vtec.

anyway, when you mean stock boost how much are you talking about cos they didn't come out with turbo.
Most likely you Greddy kit will have a 6psi actuator. So i'm assuming that will be your stock boost....

Anyway if you bolt on the kit without the ECU you will need to do that boost trick to the map sensor (never done it only know about it), otherwise when the stock ECU see boost it will crap itself.

not much more otherwise your engine will go by-by pretty quick without an ECU or tune

[andy9999]

b18c2-$3500 fast and more reliable wat car is it goin into?

[Limbo]

i'd boost anything if it was able to be done easily and cheap.
6PSI is fun in any car. Also a B15B i'm assuming it one of the older civics, so would be pretty light. Should be as quick as a dc2r with the right tuning

[andy9999]

d16y8 are cheaper anuff. under 900. and just get a kit for that be more fun then a d15

[chauster]

b16a fun enough. na is best.

[JasonGilholme]

b16a fun enough. na is best.

:thumbdwn::thumbdwn:

nahhhhhhhhhhhhhhhhhhhhh

[sPoOnD_]

ek sedan..hmm..yeh 6psi shld b enough..:D

if you wanna run more boost, you can get a turbo bottom end rebuild kit (including vitara pistons for low comp high boost) from www.fjdistributors.com for around $350 shipped to australia. apparently many people on d series have seen 250-400whp with stock heads with this setup.

[d15z1SUX]

good luck with ur turbo build man :) actually if u want to turbo i think u should just keep ur stock engine.

[sPoOnD_]

my engine nw has done 277000kmz lol..nah i aiint aiming big hp or anything ey :)

[hisoka]

rebuild it first lol~ u can buy same engine for 900 bucks btw~so yer i would be rebuilding it instead of buying new one

[SeverAMV]

hence i was suggesting an fjdistributors bottom end rebuild kit. for $350 shipped, you get the vitara pistons, all required bearings, a 3 layer metal head gasket, water pump, etc. and all necessary gaskets from the sump to the rocker cover. then all you'd have to do is mill the head and maybe deck the block a bit, if you wanna be a perfectionist, bore out the block half a mil (75.5mm pistons dont actually cost any extra), and youd have a motor well equipped to handle boost (and probably for less than the price of a new stock motor).

[hisoka]

ye severAMV on the right track,

[Lukezen27]

ye severAMV on the right track,

BUT!

You well need a far better turbo and so on if you go down that road.

This in turn adds a lot more $$$ to the setup

[hisoka]

yer so as i said before b16a or b18c and call it a day

[trism]

some people dont like teh idea, as the sump and gbox hang alot lower than the d series.

when they are already only 7cm high as it is, you dont wanna risk the b series lol

im having this dilemma myself

[hisoka]

ohh ok~never thought of it that way actually lol

[trism]

if you want twincam d series, get a ZC motor

[SeverAMV]

i think fjdistributors also started selling turbos, if not, you can find a fair few bolt-on kits that will need minimal custom work to fit over to our local civics. plus, isnt the turbo that comes in the greddy kit capable of handling 1.3bar boost relatively lag free?

twin cam zc is an expensive engine, in that practically no one makes bolt on parts for it. single cam engines easier and much cheaper to play around with. i've seen metal head gaskets for a b cost more than the full bottom end rebuild kit for a d.

i guess you could say i recommend getting an fjdistributors bottom end kit for turboing. i generally dont see much point in forking out a crap load of money on just a turbo kit and making about the same amount of power you could get from an NA with less money.

I've had fjdistributors on my browser fav's for years now but never got round to buying anything yet lol

Guys in the US say the GReddy turbo can handle 1.5Bar fine :thumbsup:

[myztery]

can any one tell me the specs for this twin cam zc engine...
or where i can find out

[Lukezen27]

Google ZC DOHC none VTec

There's shit loads

[hisoka]

i think its from a crx ?

[Lukezen27]

i think its from a crx ?

And EG SI

[nd55]

> can any one tell me the specs for this twin cam zc engine...

D16 engine, same geometry 75mm bore, 90mm stroke. DOHC cam head.

Late eighties, early nineties ish motor IIRC and thus pre VTEC.

Zero after market support.

IMHO, all D16s' are rpm bound due to the 90mm stroke, not valve area/lift bound.

ZC D16 gearboxes had the intermediate shaft and equal length axles.
About the only real plus over a late spec d16y, but that's what lsd's are for.

Nick.

[GSi_PSi]

get gsi motor cheap and more powerfull than d series

[Limbo]

there is a cheap one with gbox & engine going for i think $450. Dupac is selling it.
Might be worth while whacking that in?

[Centurius]

> can any one tell me the specs for this twin cam zc engine...

also known as:
D16A8 (aussie CRX's and EG Si's)
D16A3 (earlier tegs)
D16A1 (us market)
D16A9 (euro market)
ZC DOHC (jdm market)

helps greatly when you're looking for aftermarket support around the globe. not the easiest to find, but not that bad if you know what you're looking for.

they also had more power and tq than any newer D i'm aware of. and my stock D16 CRX would trump a stock GSi every time.

check out CRXAus forums if you're after more info, seeing as though CRX's are probably the easiest/most abundant source in aus.
