B16A head on D15B block

[SER_GTR]

Get D15 Or D16 VTEC Head And Change What You Want....!
But Head Swapping Of B Series On D Series Block Is Not Possible.........Dimensions Diff + Oil Water Routes Diff......!!!

[moak89]

@Suzuki1. not the same thing with honda

[levin]

moak: do oilpressure pumps produce same pressure? if passages of head and blocks fittings are same in diffirent Honda engines

[moak89]

@levin. no the oil pumps dont produce exactly same amount of oil pressure/ oil flow..
btw im only talking about the D series here.

Hey asad! You recommended the ZC pistons to be used in the D15B, but the ZC its self has a compression of 9.5:1, which is .1 less than what the D15B has? How will it raise compression on the D15B?

[moak89]

@ayaz. its not just about the pistons..
its about the combination of crank/rods/piston/head/block.

the main reason that u would get the raise in comp with the zc pistons in a d15...is because the zc head has alot more combustion chamber volume in the head...where as the d16/d15 heads dont.

by just placing the jdm zc pm7 (which are domed) pistons in the d15b (with the shorter rods)..and using a thin headgasket...ull get a comp ratio of 10.8:1

then u can shave the head/block a 0.8mm or so...to increase the comp ratio further
which will result u with a 12:1 comp ratio

OR
u can get a d16block/crank/rods...the pm7 pistons...a d16 or d15 head..which will result to a 12.5:1 comp ratio...without any head shave...quiet high isnt it.

there are lods of combinations that can be done

@lowres, bro, are you kidding me? vtec not in D series??

please enlighten me on the d series not having vtec

[moak89]

@ahad. i think hes talkin bout the agressiveness of the vtec engaging.
@lowresolution. ye yr rite vtec dosent kick in as hard it does in a B or other honda dohcs...thats cause in the sohc... only the intake valves camlift is changed when vtec engages. where as in the dohc's... both the exht and intake valve camlift is incresed.
therefore having the vtec coming in harder.
but yea..want me to show u a n/a D that engages vtec like a B...even though its auto. lol

@moak89

Interesting!

So the ZC pistons in a D16 from the 96-00 Civics over here would result in a 12+ compression? What pistons would suit the D16's over here for, say, something like 10.5 compression?

[lowresolution]

@moak
Correct ..!
And the VTec aggressiveness of B , H and K series over D is accepted world wide ..! so its not just me
and u explained the techinical stuff pretty nicely by yourself !

[moak89]

@ayaz...if i remember correctly.. the pm7 pisons in the d16's over here would boost up the comp to 13:1 (with thin headgasket)
thats because the obd2 d16 heads have even smaller combustion chamber volume, compared to the obd1 d16 or d15 heads.

to get about 10.5:1 with the obd2 d16s...u would have to use the pm6 (from d16a6) pistons...along with a thin headgasket.

there are lots of Dseries compression calculators over the net...try to google them up.
i used to spend lots of time on them... making combinations for a high comp d15/d16

Thanks

And about the aggressiveness of the VTEC on the D's, you mentioned some car with a very aggressive crossover. Which one is it and how did it get to this point?

P.S: How come you're not online in my messenger?

[shrm1]

@ Moak/Asad: I called you yesterday but no answer. Then i called Tariq and had a nice chat.
Opt 1. I am now thinking of swapping a LSD tranny along with the required changes like distributor etc. Then, also changing the head to a vtec one. Hopefully this would do for the time being.

Opt 2.Tariq also suggested to just swap in a B16 auto. Due to inavailability of manual. Although the horses will be significantly higher in the B-series, the feel of a manual tranny is a different world all together.

Tell me which is a better option?

[palaykhan]

B16 way to go.!

[moak89]

@ayaz. no prob bro.
n yea i was talking about a project that i just did.
i swaped in a jdm sohc ZC motor in my cousins 95.
hes crazy for auto trannys and would only drive autos if he had the option...he sold 88 auto accord and bought a 95civ...then we swaped in a sohc auto ZC.
that motor we got is in great condition...great power even though its auto...and.. it just is that way...it engages the vtec almost like a B...

about msn...my msn is messed up...:(..hardly come online using online msns.

@shrm1. man my cell is always layin somewhere around...so i prob missed yr call.
n ye yr right...auto wont be as fun.
there are limited sohc lsd trannys left in shershah...costing around 20-25k
a vtec head would cost around 5-7k approx..
first of all...tell me whats yr budget?
or yea just give me a call right now...

Salam to all,

I just wanna know that can d15b3 can be converted to d15b efi vtec one with swapping with head only?.

Can its old block can be used with head of d15b efi or else?

Basically friend dont want to replace his civic engine and dont want to get into hassle of replacing old engine number with new one.

So is there any way that engine can be converted to some d15b vtec efi engine keeping original engine no?

I m totally dont knw about this engine swapping but thats wat my friend asked me to ask someone...so i posted it here:)

Thanks

[shrm1]

@all: guys i need some more advice. Here is the complete story.
After getting the engine swap, what i have in my car is a breed on its own.
I have a D-15b block, with D16y6 Ecu, p2j head and p2k air intake. The engine has 4 codes.
1st code: VSS (thus the vtec doesnt engage).
2nd code: something to do with temprature
3rd code: engine is consuming too much fuel
4th code: I dont remember exactly.

Dilemma: p2j ecu is not available. the head is not all that great (i mean the vtec head i just installed). Wiring is messed up, which will cost about 3k to re-wire/fix. Fuel average rite now is 4km/ litre. If i drive it on Cng, the water runs dry after about 30-35kms.

I have an option to swap a complete d-15b with lsd manual tranny for 50k installed. or i can unload a few thousand to put some life into this engine.

What can i do?

[ahsan1702]

@shrm1

Can you tell exactly which codes the engine is giving ? Code number I mean.

Till you sort those out, you are going to get problems. Tinker around ... get whole new wiring and a p08 ecu and you wont have any issues.
