D series Engine~ Vtec

[chingaling]

could someone explain what is the difference between SOHC VTEC engines ( D16a , D16Y8, D16Y1 )

As i know that D16a is a JDM motor.. and Y's are AUDM.. any difference in output? and mounts and ecu are same ? correct me if im wrong thanks would like to know more info about it :thumbsup:

thanks for the info it helps a lil bit. .. coz the engine block num i saw it just say D16A and it didnt had the on the web site.. is that a ZC jdm SOHC eng ?

[NeRV]

was it dohc or sohc? got any pictures?

[onlykillzz]

double over head cam , single over head cam. double is better in so may ways. and im not shore but i think vtec has more of an affect with a dohc rather then a sohc

[supersamEK]

yeah sohc vtec adjusts lift only on intake valves... whereas dohc vtec is on both intake and exhaust side.

For the D series, the DOHC models don't have VTEC.

im very sure... this engine im getting it doesnt come with ecu im not sure which ecu am i getting is it the p28 ecu? and its also a Autoo trasmission.. will i be able to hook up the manual gear box in with no problem or do i need to change some thing?

That's an SOHC VTEC. Since it's JDM, you can't use the wiki article to determine what it is.

since its a JDM motor is there any difference in the ECU and Mounts ? also power out put ?

oh this engine, i was about to buy this for my cousin. i did some research on this motor, it was originally non vtec, i think the last owner did mini-me on it.
because d16a are the ek (non vtec) sohc engine in US.

Well i dink this motor has the jdm d15 vtec head, d15 stock is 100kw(?)
I guess the output power should be greater the y1 and y8
That's what i found.
Can someone confirm

[EG5[KRT]]

thats looks like a d15b engine jap spec

sohc vtec with 130hp from a 1.5 litre.

comes from a eg esi/vti

[aaronng]

In that case, probably a d15b head on a d15a block like what Phuong1987 suggested.

Yea..but the replacement series for D is B..and they are all DOHC models,u can see that most CRX and Civic Hatchbacks are running on B16a or B18b in Japan..and the power output is much higher than the D series as the B series is made for racing purposes..

so wahts the purpose for D ? lol curious :p

[Greylock]

D series are older than the B if i am not mistaken and the situation is like the new K series taking over the B series now..the new and improved version will take over the current one.

[jdm_kid]

i like he D series. its a strong motor. even if u turbo it, it wont crack for a long time. good for a daily driver or for fun - http://www.youtube.com/watch?v=kbZg8QBJaMM lol

Not really. There are always 2 lines in Honda engines. One is for fuel economy while the other is for performance. The replacement for the D is the R series, not the B.

D and B series
F and H series
R and K series
