d16a8/9 (came in tegs 88-89)

---------------------------------------------

ok now what i dont get it this. a d16a1 has the exact same bore and same displacement yet it only makes 113hp?

what the hell is going on here. is this a d series that is worth investigating?

Re:D16A8/9
 

shortyz..

All the ZC's and most 1.6's D-series have the exact same size bore and stroke..

The difference in HP is made up in.. Camshafts/Intake manifold design/ and ECU.

Keep looking, at specs, I have seen d16a8/a9's rated at like 128hp or so.. (edm engines)

I have a D16A8 in my EDM 1st gen 87' CRX it's with the brown cover.
Jeff is right it is rated at 128 or so hp.
As I have heard the D16A9 (black cover) has a slightly different intake manifold and other cams and the ECU is totally different.
One good advice .... don't get the EDM 87' ecu's They suck.
It has a automatic choke that suck ass big time.
If you have problems with coolent leaking ro waterpump broke that choke is gonna choke your wallet to dead with a mpg that even my father's Camaro laughs at.And that monkey ass vacume advance... >:( ...If I change to electronic advance do I need to change to another ECU?

Re:D16A8/9
 

ive heard that the d16a8/9 are in 88-89 integra's but i yet to see one....its strange i go to the junkyard and i see 88-89 integra's with the d16a1 in them....ive never seen a d16a8/9 in any of them....and isnt the d16a8/9 also a ZC ? or something like that ?....im going to order a ZC motor in like 3 weeks and i dont want them to order the wrong ZC...i want the one that jeff has...the black dohc valve cover.
how should i be specific with these fools at the performance shop cause there derlicks and they really dont know whats up.

Re:D16A8/9
 

d16a8/a9's are EDM European Domestic Market, good luck ever seening one of those in the states..

"...If I change to electronic advance do I need to change to another ECU?"

I am pretty sure you have too...

Jeff

Re:D16A8/9
 

If you change to electronic advance you will definitely have to do minor wiring and find another ecu. Get an ecu from an 88-89 integra, the 86-87 brown tops have vacuum advance.

Re:D16A8/9
 

The 88-89 tegs here are a piece of crap.
I just found a 88 crx at the junkyard picked up it's ecu and dis etc. ;D
By the way I live in The Netherlands as in Europe...
