Silly me:)

Single stage or base/clear. What brand. Absolutely need new hardener. If you are paying to get it done you may have trouble getting the paint shop to get onboard using paint of unknown origins. Derek

That looks normal to me for glass beading. Raw castings are usually shot blasted then machined. I found that putting parts in a vibratory finisher after blasting restores some of the luster. I can fit my DOHC valve cover in my finisher. If you look closely you can see the difference. V3 is in the foreground and it has been shot blasted and then run in my vibratory finisher with burnishing media and liquid. V2 in the middle has only beed shot blasted. You can see a slight luster on V3. Here are two parts I glass beaded. And here they are after vibratory finishing. There are many types of finishing media. Burnishing media is what gives the parts the luster. Derek

Project Cars 2 Racing Simulator with Datsun goodness
Derek replied to 260DET's topic in Motorsports / Events
Well that looks like fun. I was messing with Rfactor for a while and even started modeling a 240Z for it. I decided to make a twin cam head instead:) The thing I noticed was it's more about the physics settings on the car more than the look of the car. Garbage in garbage out. I may have to pull my driving seat out of storage! -
I think what project binky showed me the most was that you can fit stuff in the space pretty easily. Getting it all to work properly without killing you is the tough part. What good is all that effort if it handles like a mini van.

Twin cam head for the L6 from Derek at Datsunworks
Derek replied to Derek's topic in Nissan L6 Forum
V3 is going on a tall deck 3.5L with a custom crank and pistons. Normally aspirated. Should be high 4's for horsepower. -

Since I'm planning on trying out VCT on my build I figured I'd better finalize the valving. For me it's alway a balance of (not necessarily in this order) function, manufacturing and style. On the VCT it's always function first since what's the point if it looks better than it works. I knew what valve I wanted to use ( manufacturing) and where it needed to go (function) but not how to make it work ( manufacturing ) and not have it be butt ugly (style). I picked the valve I did because of the fact it came with it's own manifold. This makes manufacturing a lot easier since I don't have to do any precision boring. Since it's an open pressure (bleed) circuit believe I need to locate the valve as close to the cam phaser as possible to try and minimize the response lag. I also have to deliver a pretty good volume of oil at times where a fast response is necessary. I mapped out the valve with the 4 circuits. Oil in, 2 drains, advanced and retard. The valve is a spring return and defaults to retarded cam position. Retarded seems to be the default for the phaser as well. Which makes sense. Lets start with the fact that I'm not crazy style wise about hanging this valve off of the front of the timing cover. But it's the closest I can get it to the phaser and still be able to plumb it. Here is a shot of the final plumbing. Red is oil in. Light blue are the drains. brown is retard and purple is advance. Since I didn't want the valve there to begin with you can imagine how I felt when I finally gave in to the fact that I needed a .625" thick manifold block to handle all the cross drilling. I tried a bunch of scenarios but it would have added a ton of time to the machining because of doing that kind of work on a short production run casting is tough. I also had to flip the valve 180 from my original position to get the advance and retard ports to match the head. It's all about compromises in life:) Derek: -

Family Portrait. V1 V2 V3 I snapped this before I shipped V3 to Rebello and V2 went for a visit to it's owner. Probably (hopefully) the last time they will be all together. My feeble attempt at an art shot Things move pretty quick around these parts:) -
I went the patch method as well and like others it just cracks in a new spot. Here is a pretty long how to on bonding a dash cap to my dash. It's been over a year and up until I trashed the head it was sitting outside daily in the florida heat. There are no signs of delimitation. Not the cheapest rout but if you do it right it's probably the last time you will need to do it. Derek http://forums.hybridz.org/topic/125411-advanced-dash-recover-project/

Mr Monkey you really need to pay better attention. Post #1116 clearly shows VCT being implemented. You are receiving 1 demerit Here is one of the pics to make it easier -
Geez Paul you haven't posted since 2015 and this is all we get:)

I think the throttle bodies with the built in bungs are the way to go if you already have a DCOE manifold. For me at the time the kit was appealing because I knew I wouldn't be constrained design wise. Now if I was going to do it all over again....Heritage Throttle Body all the way. That is as long as they get around to doing it in 48mm like they said.

When you add up all of the stuff in the kit purchasing them piecemeal the price goes up quite a bit. Now if you are going to discard some of the parts like linkage then it makes better sense to buy individual. Also the ones you linked to have a built in injector bung. Which is a plus if you want it. The kit I got requires bungs in the manifold which is what I wanted.

I'm happy with mine for sure. One of the butterflies is slightly off center and it has a little stick-age problem if you run closed blade idle bypass but if you crack the blades for your idle it's not a problem. The outer edges of the bodies were sharp but that was fine as I just hit them with a deburing tool. The kit had everything I needed to get it working. I did manage to knock one of the velocity stacks off of its base but it snapped right back on and never was a problem again. I had about 6000 miles on them before my head $hit the bed. I think for the money they are the best deal out there.

Oil pump for mild enduro race car? Stock NA is fine?
Derek replied to turbogrill's topic in Nissan L6 Forum
I'm running the Melling M111. I did some volume tests and was pretty satisfied with it's output. No hard numbers just testing when I was initially setting up my DOHC head. Derek -
Hey those look familiar.

You can post the pics directly here if you want. That way you don't have to go through this dance every time a hosting service decides to cash in.

Putting the finishing touches on V3. I decided to put the head back in the mill to do more work to the face. This is no easy task because I have to hang the head off of the table and rack the mill over. Originally I was going to put the sealing o-rings in the sub plates. I realized that this would make it really difficult for someone with a manual mill to make new plates. I also determined that the idler sub plate was going to be around 6mm thick. This wasn't going to be enough meat for the bolt so I made a pocket in the head so that the plate could be thicker in that spot. The oval holes are oil scuppers. Oh look a pile of speaker panels on the floor:) I had to offset the bolt holes on the idler to miss an oil passage. I'm so happy with the sub plates that V2 will be going back in the mill for a modification. Thanks Derek -

Since I get a ton of traffic on this thread I'm reaching out to HybridZ members. Dan is having trouble funding the site due to diminishing ad revenue. There is a funding drive going on here: http://forums.hybridz.org/topic/127731-hybridz-may-be-shutting-down/ I have donated 5 sets of speaker panels with 100% of the sales going to HybridZ. Two sets are gone so you better hurry:) No need to comment here just follow the link and donate. Thanks Derek -

Putting the finishing touches on V3 before it heads out to Rebellos. Decided since there isn't a head on my car now would be a good time the check the hood clearance with the higher valve cover. And....It fits Running a tall deck will probably require a low profile oil cap. Sniff sniff....I wish it was mine:) Kind of looks like it belongs in there. Derek -
Yea that is on my list for sure.
