yup exactly why I said they give good head. Blocks aren't that great, I'm pretty sure the oiling passages on the crank are smaller diameter

Re: Searched - Best D-series to build?

JD spoke of the y8 heads giving him troubles with boost a while back. If I was going to boost any d, it would be the d16z6. A6 would be a fine 2nd choice.

Re: Searched - Best D-series to build?

i dunno why everyones stuck on the sohc bs.... the ultimate d series is the dohc zc IMO

bigger intake valves than any sohc motor, and the exhaust are the same size as the biggest sohc motors.

it might be slightly harder to source parts, but with a will theres a way, i have plenty of goodies on mine....

straight from JG engine dynamics. look them up they have dynos of 300hp b series race motors ect....

Notes: If there was ever a head porters dream it would be the ZC or D16A9 head.
These heads were produced in a time when Honda was really not after max
performance. As a result of this they left a lot of room for improvement. Hp gains in
these heads of 25Hp are not uncommon in race engines with no other modifications.
In these early heads since there are is lot of casting flaws the stock ports flow as
much as 10% from one port to another. Compare that to a more modern head like a
GSR that flows with in 1.5% of each other. Fixing this alone is a large improvement
and our Redline or Pro Series head does this. These heads also have room for
enlarging the ports and raising them for some really large gains in cfm with out
loosing velocity. These heads also have a really large chamber with no quench area,
and lots of room for welding. Gains of to 1 full point in compression can be safely
done without the need of changing pistons or excessive head milling. This cost of this
service is an additional $150.00. For more info, visit our head section of our website.

With the money you will spend to buy a dohc ZC you could have went b18 and made more power. sohc are dirt cheap and a dime a dozen.

its all about the D

Re: Searched - Best D-series to build?

I'd say boost whatever is in the car. FJT has rods for D16's and soon for D15's. I boosted my Y7 and then it also spun a bearing but he took a daily beating of 14psi.

Re: Searched - Best D-series to build?

JDM yo D15B with a FJT package.

Werd. Go with what ya got. You are going D for some cheap fun I am guessing. So just dance with who brung ya.

Re: Searched - Best D-series to build?

If I ever find a cheap or free D15 then I'm gonna build one. Hell I don't even have a civic for that matter. It'll just encourage me to get one though. lol :P Seriously, just build what you've got or I guess if you want to build something on the side and keep the car running in the mean time. I'd still go with whatever you can get the cheapest. Now that FJT will have D15 rods that makes those B2, B8, Z1's etc... lumps people pulled out worth something. Not saying they weren't worth anything before but atleast you can make some numbers out of them.

Re: Searched - Best D-series to build?

Come up to Steve's pad next month when Julio and I are there and bring it with you. Otherwise I'm not sure when I'm heading south anytime soon. But consider the block taken when we meet up again bro. Not sure what Senior Bustamante and I are doing. We might head down that way as he wanted to check out King Motorsports. Should take like a whole 5 minutes as it's pretty small.
