Yep thats the EDM DOHC ZC, no difference.

Beware of the EDM D16A9 though, looks like a DOHC ZC & a D16A8 but 13 less HP and lower compression pistons.

If you have a Si, Hasport sells the wiring kit (Si - DOHC ZC) for like $40.

Other than that use your Si tranny if you dont get a ZC tranny and youll be on your way.

like any other D- series or B-series, Your gonna have to put Rods and pistons and other goodies on it then they will all be reliable.

Your not going to get 300hp out of a stock motor.

right, not with a stock motor, but with pistons, rods, balanced crank, cams, camgears, springs&valves, port&polish, msd ignition, and hopefully a full greddy kit & engine management is 300 possible?

What a b*llshit.

Both of the engines have 130hp/6800rpm and 153nm/5700rpm. A 9:5.1 compression, pent roof combustion chamber and PM7 components. Same pistons in both of the engines.

I should say beware of the A8 cuz its not from Honda actually. A9 is. Where did you come this info anyway?

And use search, i've been telling the diffrences from A8 and A9 for a dozen times.

Dude you live in Europe you ought know the differences better than anyone, But yes in EUROPE it will make 130 (A9).
The A9 has lower compression and is meant to be ran no cat, and on LEADED fuel, something we dont have in the states, thats why it achieves 130hp from being a downgraded motor. And just because the A8's are in Rovers does not mean they made them its still a Honda motor.

I dont care where you live, youre still wrong, even if you lived in f*cking Japan!
I get this info straight from the Honda spec sheets from Hondas website!!

I can get these information, not from internet. From Honda Motor Europe Co. And i can show you the "diffrences" in A9 and A8.

BTW, we havent got any LEADED fuel for a century. The A9 is CATTED in some european countries. I can prove you that. Dont start to arque with me on this.

BTW, this is from Honda catalog (witch was given to retailers in 87 when the new models came). This does not answer to all of your questions. But answers that the D16A9 engine DOES have 9.5:1 compression, and 130hp.



I've read about the "9.1:1 compression A9" from the internet too sometime. Internet is a very good place, no doubt. But people can put there something that they necessarily not know everything. And then people reads it and think its true information. Like this kinda information.

as you said, this has been covered before. and when it was, you were wrong atleast once. even getting the info directly from Honda, they have conflicting info (which, again, has been mentioned). Honda UK has 2 online manuals (CRX and Concerto) that list the D16A8/A9 and each has differing compression numbers.

if your info says the D16A9 has 9.5:1, that's fine. if you want to take that as the real number, that's fine, too. but there's no need to get self-righteous when other people quote other figures that are also directly from Honda. it's not helpful. i'm not trying to be an ***, i'm very glad you contribute, especially since you're on a different continent that has cars with different engines and specs.



to the original poster, here is a little info on the ZC/A8/A9. i have a D16A8, and i have no complaints. i also haven't heard any complaints from anyone who has swapped one in.

Wow you are wrong. There are plenty of people in this forum that have turbo DOHC ZCs (same as A8/A9) and are making nice HP without changing their rods/pistons. Its all in the tuning.

Also, LS engines make 300hp on stock blocks. Go to the FI forum, you will see plenty. Especially in the thread just disignated for the LS-T setups. Again... its all in the tuning.

And there is a STOCK BLOCK K24 making upwards of 500whp. Did i mention it was stock block?

Make sure to get larger injectors and an upgraded fuel pump. Low compression pistons.

With the setup you mentioned, proper engine/fuel management, and a nice turbo, 300 hp is easily obtainable. You can probably push ~450-500hp. But again (for the third time) its all in the tuning. Proper tuning is the difference between a rod out the block and a strong, healthy turbo motor.

I gotta stick with Twilight. Here in Venezuela we got the D16A9 engine, and Honda Venezuela have the same specs. 130hp, 9.5:1 CR.

I have the UK CRX manual, and it says the A8 was EFI, whereas the A9 was carbed, but I don't know if that's true. All venezuelan A9's are EFI, and without cats.

who says the Fins don't have a sense of humor?!


Starscream... i don't doubt that at all. manufacturers release all kinds of variations in different markets around the world to meet specific governmental restrictions and consumer demands. there are very obviously differences that need to be mentioned, and not fought over.

unless you know exactly from which market a specific imported engine came from, and exactly what the specs are for that engine in the given market, there's no need to fight over it.
