Hey all. I think I have decided to go the SOHC route. I have about 1000 dollars to spend on an engine. Which do you all recommend? I know that the D15b is the D16Z6 replacement but why? Which is the better motor?

One other question, kinda off the wall. I just bought my 90 Si hatchback but the original engine has been taken out. I have been told I have a D15 block with an Si head. What does this mean? What kind of head would this be. Is this considered a "Mini Me"?

Thanks!

 

how is the d15 the d16 replacement? I have a z6 in my car with a l3 trans and it feels better than my b16 that i had in there.

 

why dont u just buy DOHC zc u can just buy motor and pm7 ecu for 900 prob. less.but if u wanted to go single cam route i would have to say nicely built minime would do just nice.maybe small if u wanted.thats just my 2cents.

 

Z6 would prolly be easier to get a hold of. Might be cheaper too because their are more of them around. I would get the D15 because not everyone has them. My opinion though.

 

z6 are actually harder to find and cost more then the zc and the d15b. i was trying to decide which motor i want in my car. i have a mini me right now. i was going to buy the d15b but i decided not too. reason being aftermarket support. so now im trying to find a z6 due to the tremendous amount of support it has. if something was to break i can easily just buy a replacement at advance auto or some ****. d15b are like 600 shipped from HMO

 

d16z6, thats what im building, expected to red line at 11000 rpm, what now b16

need anyparts ask.

d16z6...

 

whats the advantage of the z6 over a b16a ??? just curious cuz u mad single cam people swear by them... o yea im runnin a d16a1 i think.. cant member off hand lol... but its the 91 crx si motor non vtec gettin rdy to get a b16a so just curious

 

There are different types of setups. There is d15 bottom ends with 1.6 heads. Depending one what your lookin for. I would go with a d15b out of a 92-95 civic . Its girdled on the bottom for some strenght the sump is a little bit bigger i think and then toss a 16 valve head on it. Either it be vtec on non vtec. You can get some good numbers if you were looking for high compression i beleive you use ZC pistions in a setup like that and get some high compression. I myself like the 1.5 just cause the bottom end is pretty sturdy cause of the girdle on the 92-95's. Thats my .02 cents for ya

wtf? wow... im assuming your talking about the mini me...and 1.5 rods are not as strong as the z6 or even the d15b. the d15b your talking about is total *** junk. we are talking about the d15b 1.5 liter VTEC HMO also has the d16A which is supposed to be equilvent to the z6 1.6 vtec.

 

I would go with the al mighty JDM D15B Vtec, period. Why?

1. nice preppy engine and revs really great, if not awesome
2. Reliable/Easy to maintain
3. Drop in motor, well except for some little modifications
4. Welcome to Vtec
5. Parts are easy to get and at good/decent prices as well as NEW...
6. I've seen great set-ups with many diffrent D-series motors take B-series engines on doggy walks....dont get the wrong idea here, but i know you guys have seen a D take on a B.......

If you have the budget go for it, I can tell you right here, right now, both my D15 Vtec+SI tranny= less than $600 spent...

if your sticking to one cam

me i liked my a6

 

Are you sure you dont have the OBD0 D15B from the HF series? If you do have somewhat of a "si head" check for the head stamp, vtec solenoid and year of the head. I dont remember the code exactly it might be p08 (as for the obd1 sohc vtec head).

The jdm obd1 d15b is exactly like the d16z6 except for cams and blah blah blah but i've had both and both has felt the same.

Here is a list of the jdm to usdm engines...which are very simuliar to each but may have a "aggresiver cam" in it.

obd1 jdm d15b -- the usdm version is the d16z6 92-95 civic ex / si
obd1 sohc zc vtec -- exactly like the d16z6 like above
obd0 sohc zc -- the usdm version is the d16a6 from the 88-91 civic ex/si & crx si
obd0 dohc zc -- -- the usdm version is the d16a9 from the 1st gen integra

 

well if ur looking for a d16z6 motor..try look for it at autobody shops(that sells cars) or mechanic shops..they most likeley have a motor sitting around collecting dust...i got mine from an insurance auction..a whole car with 75k miles..

 

I am not exactly sure what the engine is. If I were to take a picture and post it, would you guys be able to tell me whats up?

 

You'll want to do some independent research/verification on whatever facts you pull from this thread. There's so much inaccurate information that I'm not going to try and correct everything.

The D15b is so popular because they are cheap, swappable and perform roughly like the D16z6.
And the D15b is typically low mileage...which you will not find in a used D16z6. Anything under 100k on a z6 is considered low miles. And since the z6 was in the Si and EX, both popular with the speed racer wannabes, they've typically been flailed on pretty hard.

 

exactly, thats why go with the d15 lower milage and a tad bit cheaper then the Z6, the Z's have been a popular set up since they are easy to aquire and rebuilt for custom trubo set ups as well. just get as much info as you possibly can and then decide what you will need exactly and for that swap.....

post pics of your whip and motor let us see, so we can direct/advice you what you might consider doing before you blow a hole in your wallet...lol

 

D15B with Si tranny=Pretty Fast

Just bought the Si tranny for $150 and bought the D15B Vtec for $255=$405

 

Here are some pictures of my awesome engine. I know what block it is but I have no idea what head it is. I'd rather not buy a new engine if I have to but I would like to make whatever I put in this thing a performance engine. By performance I really mean i'd like to be in the 13's. Anyway let me know what's up because I am an uber noob when it comes to this.

Um not exactly i am talking what is equivalent to the mini me minus the vtec head. I am not a tard here i know what the mini me is. I am talking about the d15b which i current have in a running project with a non vtec head from a 1.6 d16 whatever the hell it is. Its just like the mini me minus the vtec. I am familiar with the d15 b vtec also. I have seen some setups using this for turbo. Also the d15b which i current have running is not garbage i have seen this block bone stock on 15lbs of boost b4 so if this is what you call garbage man you must be throwin out gold.

LoL.

Which cam?

 

Yes that is a hf motor alright. I can see the skinny intake manifold.

 

umm first off the JDM version of the d16z6 is the D16A which is also 1.6 vtec. the d15b 1.5 vtec isnt the equilivent to it. its got less torque but i guess not enough for you to notice.
