If you had to choose one motor to put in your car which one and why??

 

they are very equal, both are ok. use what you got or whats cheaper.

 

well the z6 has more horsepower, why not do a6 block with z6 head ?

 

depends on the budget, the z6 costs more to do it right with a p28

 

I would never spend the extra money to convert to OBD1 for the extra 10 HP.

Well some ppl convert their cars to obd1 because there is more tunning, and also if you wanna change from sohc vtec to b18 Dohc Vtec... Its easier to swap.....

Is this a good set up?? Would you do the A6 block over the Z6 block?? I know people who have said the A6 is the best d-series engine Honda made but again everyone has their favorites.

 

better as in...

are we talking stock for stock?
sheer potential?

the a6 and z6 shortblock are basically the same from what I know (except the a6 mains are supposed to be a little thicker)

as far as cylinder head design I don't know cause I have never seen an a6 head. I would imagine that even if the combustion chamber and int/exh ports were identical you would still want the z6 head due if you would like a streetable low-cam and higher vtec-cam power. also, it has been my experience that there seem to be more of an aftermarket for the z6 head making it more desirable

 

p.s,

the most powerful street turbo and n/a d-series engines I have seen have z6/y8 heads

 

The z6 has a better head, but the a6 has a better bottom end. Stock, the z6 is obviously strong enough.

 

imo with a friend that used to own a 93 si, and me with a 90 crx si he could never lose me, and it felt as though i had more bottom end. but there two totally different cars so...? but since i own a few a6's i vote a6!

 

So then I ask again:A6 bottom with Z6 head is this a winning combination since what I've read so far???

 

its called mini-me, there are tons of info..... You will have higher compression with an a6 block and a z6 head..... Its not the best combination for SOHC vtec that I have heard off.....

I heard that the d16y7 block with d16y8 vtec cylinder head will be the best mini me combination.......

 

sohc vtec is a joke, swaping a a6 car to a z6 for no reason other then wanting the extra 10hp while killing your low end torque (what little is there) just isn't worth it. Save your mony for a dohc zc or b series or turbo

 

ok so the mini me is basically an ls/vtec. except its single cam, and less power.
The z6 has about twenty more ponies. The reason the crx stayed with the del sol
is that the del sol weights an extra 400lb or something like that.

But exactly what everybody else said, whatever you find a good deal on.
You could get the z6 motor but still run your si tranny. Save money by
sticking with the cable tranny.

So your car will be faster than any stock crx. Faster than the stock zc.
And you can make some pretty good power out of it.

With the money it would cost to get and drop a b16/18 or whatever
in the crx. With half of that money you could make as much power.
Go to d-series.org you'll find some great stuff.

Get the intake, headers, exhaust, and some other toys and you'll
fell the differance.

 

I have personally used the a6 bottom with the z6 head. Its better than stock and the compression is higher so you will be faster than a stock z6 as well. As for the blocks, Honda put more webbing in the z6 block that makes it a more stable block, however the mains on the a6 block are slightly larger to compensate for less block webbing. I assume that Honda did this for the z6 to put less metal into the block to save money and wieght. I perosnally would use, if i had the cash, the y7/y8 combination. But I am currently building an a6/y7 block head combination because the newer heads have better flow and i think slightly larger valves. The a6 head is kinda shitty and thats why it gets tossed most of the time. Not to mention its ugle compared to the newer vtec or d16y7 heads. The a6 blocks are the cheapest to find so I use them and run the newer heads. PLEASE USE ARP HEAD STUDS. the a6 block flexes more due to less webbing and therefore needs stronger bolts to hold the more powerful/better heads.

thats my .02

 

if u wanna do single cam all motor i whould do that a6 block with z6 head the a6 has high comp pistons ) slap a zex 59300 cam or some **** get tunned and i bet it whould be a pretty nice motor

there isnt anything wrong with sohc vtecs. they have virtually identical low end torque numbers too.

325 whp stock a6 head checking in.. i'll stick with a6's till i die. still obd0 too. thinking of converting to obd1 for chrome (better program that TurboEdit, IMO)

 

imo it depends on wht u want to to with the motor for a turbo car i would stick with the non vtec a6 but a na car you def want the vtec for the fact it revs alot higher but thts my .02

 

The D16a6 would be and is my choice who the hell needs VTEC?

 

d16a6 non vtec is the way to go convert to obd1 non vtec later and its a even better platform. there is nothing wrong with not having vtec its overrated in sohc's anyway.

d16a6 all the way FTW!!!!!!!!!!!!!!!!

 

plus the sounds of a all motor a6 is priceless plus i hear there a better platform for boost. but then again you can boost anything now a days

 

the d16a6 is a great motor. For being that old, and that reliable, and pretty good power for a 1.6 single cam.

 

mini me (d16z6 and d16a6) &gt; d16z6 &gt;d16a6 in power.

 

This is great,my longest thread to date.I think I'm going to go A6 botom with Z6 head and turbo.My question now is are the $500 turbo kits on ebay ok?? I know I can spend $2,000 on a turbo set up but this car is just going to be a weekend warrior kind of thing so can I get away with an Egay turbo set up?? Does anyone have first hand knowledge of a set up like this one:
