Difference In D16 DOHC and B16 DOHC?

[lunjiaow]

Hi, i am looking for a CRX and came across one and apparently it has a new engine in it.
The owner doesnt know anything about the car aswell.
So my problem is that i want to know which engine is in the CRX.
How can you tell from the D16 and B16 by just looking at it?

What shape is the car ?
(AUDM)

Older squarish CRX = D16a8
Newer smooth shape = B16a2

[lunjiaow]

its um the old square one. 89'

[kj887]

they are so diff, D16A r twin cams, 96kw, which are eqipped in 89 Civic EF Si (JDM), 1989 CRX si, 92 Civic EG5/EH9 Si.
B16A or B16A2 r only eqipped in EK4 civic hatch vti-r n EM1 civic coupe vtir in oz(unless oz 92 or up CRX del sol), the 1995 or be4 b16a model civic/must be JDM spec , but not oz delivery model. b16a is twin cam, 118 kw vtec....more high rev than d16a.

both r very gd 1.6 twin cam engines anyway. but B16A produces more power, more compression rate, little bit more torque, MAY BE more potential to mod than D16A. correct me if i m wrong.

also it should have d16 or b16 engraved on it.

[lunjiaow]

ok thank you guys....but would it be engraved on the engine block itself or the head?

[bigjo5]

on the block.. right next to your exhaust manifold
you should see liek a little probly 4cm square flat bit with nubmers and letters engraves so look there

justr look for one word on the rocker cover. 'vtec'. haha

[TECBOY]

both terrible engines

[lunjiaow]

so 'vtec' will be on the rocker cover....thanks for that....im checking out the car tomorrow....

[SINISTR]

my guess would be if the current owner doesn' know much about the car and engines he would not go to the hassle of swapping to a B16 in a 89 Aus Spec CRX - would have been a straight swap as a replacement.

However - if its a B16 it will have a VTEC sign on top of the rocker cover and on the 'block'.

[czy_sol87]

wouldnt it be more simple to look for the VTEC sign on the rocker cover
