I got my B16 head back from Endyne, with the quench areas opened up to 84.5mm and the chambers opened up as well. The head was hacked before I got it, chamber volume went from about 38cc to about 40cc after the machine work.
I have some large pics, too large to post but here are the links-

If anyone still has any doubts, Endyn does fine work with a reasonable turn-around time. They also corrected the bores on my block that a well known machine shop completely screwed up. I highly recommend them.

 

very nice, update us on how it turns out

 

any more pics?

 

Let me know if you want any more pics...I thought those pretty much told the whole story but I could take more. I can also take pics of the engine block with ported oil passages if anyone is interested.

Also a note- if you have your block work done by anyone other than Endyn be sure to clean the metal shavings from the oil passages/oil cooler/etc.

 

Hey, do you have any before pics??

 

No, sorry. It was a regular old B16 combustion chamber, nothing special.
Things to note though are that all the chambers have the same quench depth and the same cc. As I understand it opening up the quench is the most important part as it avoids a "stepped" quench situation that an 81mm head on an 84.5mm bore would give. This helps give some mechanical octane and cuts down on hot spots within the chamber.

 

I had all my stuff done there as well. Larry at Endyn is great to work with. Nice, wants to please the customer, does his work in a very timely manner.

This is all a D16Z6 engine and head.

Head: has been ported and polished, combustion chambers opened to 78mm to match cylinder bore, full Ferrea valvetrain installed (Keepers, Ti Retainers, Springs, Stainless Valves, etc)
Here are some shot of my head (Sorry aren't the greatest pics but do the job.):





Here are a couple of pictures of the block. I haven't even taken it out of the box yet . No time so I decided to make a winter project out of it. Take my time and do it right.




I will also be using a skunk2 Intake Manifold, Endyn Breather System, Cometic HP gasket.

 

damn, looks good! Question why single cam?

 

Why single cam first of all parts are cheap for them alot of torque.

Guy here with a 92 hatch makes 330hp and he runs 11.74 with full interior.

 

I guess the real question is why not?? Everybody and their brother does DOHC's. I wanted to be different for one. 2, I already had DSS Stage 2 axles and a quaife diff and decided I could make more reliable power building a SOHC up instead of boosting a stock block B16 or B18. I would be spending $1300+ just to get axles and the diff for a B series setup!!
Currently in stock block form and 10 lbs of boost, I annialate Type R swapped hatches. These cars are also gutted where I still have all the creature comforts in my Si hatch. I can't imagine with 20+ pounds of boost.

Exactly.

Picts look good "ladysman" What hp numbers are you shooting for?


Its funny how many people on this board think that a D16 can't make power...heheh

 

That head and block looks sick! Can't wait to see what it puts down. Good luck with the set-up!

 

looks good, also looks like you need to index those plugs

 

Cool, now I know where to send my head for some work....

 

Those plugs were strictly for cc'ing purposes.
I have to start reading the spark plug threads before I'm ready to buy plugs for the N/A and boosted stages of my setup.

Thanks
Ben

I aint stoppin til I get 400. I don't think it will be a problem on 100 octane turbo blue gas. I would be happy with 325ish on pump gas.

 

he said "Endyn...."

 

no real need to open up the combustion chamber bore as this has been borne out by portflow, importreview, et al.

also are yousure that you had only a 38cc combustion chamber...you ought to cc it just to make sure and to calculate compression ratio...b16a/b18c5 are 42.7 cc

 

I cc'd it, that is how I determined I had a 38cc chamber to start out with and I measured it again after the work and found that it was now a 40cc chamber. As mentioned in the initial post, the head was shaved quite a bit.

As requested here are a couple pics of some of the oil passage porting done by Endyn. Pretty much wherever a grinder could reach they opened up the passages and radiused all the corners so they were smooth. Here is some interesting work done around the oil filter-
