  1. Mike is that at 1:1 with the drive pulley? I think you have to take into account the pulley size of the crank pulley driving the blower.

    L16 build, head advice

    Yep I have those, I bought a eastwood kit some time ago. I'll do most of it now and touch it up after getting the seats changed and valve job if I need to.

    So after the valve seat is changed I can smooth the bottom of the seat to smooth it to the head? 20200316_160326

    L16 build, head advice

    Mike, yes to all three. And Yes I'm trying to do the little things that will add up, I will add relieving the block to unshroud the valves. Most of this stuff I can do myself and I like to do anyway. Hainz I was going to use the L20B cam that I have that was in this head. I know budget a performance don't go together and that's why I didn't even look at cams. How do you guys feel about buying and using used cams?

    L16 build, head advice

    I bought head savers and wanted to mill the head to raise the compression, I would like to be right at 9:1 with the flat top pistons and A87 head. I will always run 93 octane in this car, its not a daily driver and I'm not worried about gas mileage at all. The intake seats are bronze and the exhaust are steal. I was going to have the machine shop replace just the bronze seats and then get the 3 angle valve job. I think I understand what blending the bowl means. When the seats are installed the material just under the seat should be even with the valve seat. If that is correct, I checked my head and there doesn't seem like there is much to blend. This head does have the 35mm exhaust valves instead of the 32mm if that makes a difference. What does "relieve the area just around the valve guide" look like? thanks for the help everyone.

    Wow almost exactly a year later. I'm back on my project. Still building the L16 with flat tops and the open A87 head. I will be running dcoe 40s on a cannon intake. I disassembled the head and port matched the cannon intake to the A87 head. All I did was layout blue, installed intake, scribed a line around each port and then open the port to match the line. I then used sanding drums to just smooth it a bit about 1/2" into the port. I placed the intake/exhaust gasket on it and did the same to the exhaust ports. I didnt touch anything else, is there anything else I can do? I'm going to have the machine shop hot tank, replace valve seats and 3 angle vale job. I also wanted to mill the head to increase the compression. Any other simple things for performance?
  7. And I was looking at T3 website and they sell a big brake kit for 280zx struts that can still run 13" wheels. If I use the dynalite calipers and a smaller rotor can I make that work too or are the T3 calipers smaller? The last pieces I need are rotors and make or buy the caliper brackets.
  8. Measured the struts and the are stock length 14.8 I did some more searching and came across a post here: https://club-s12.org/forum/index.php?topic=38256.0 This is copied from that post " KYB customer service rep told me last Friday one of their tech engineers would contact me about this. As of Monday night no one had but Tuesday morning I received the following: Good Morning Please ensure that all liquid and any obstructions have been removed from the cartridge housing. KYB cartridge will not install flush with the housing but the gland nut will go no more than ¾ of the way in. This is normal for our product is [sic] you would like to get our gland nut to go on further you can file some of cap on the bottom down but do not remove or break off cap. Thank you Tech
  9. I'll have to measure when I get home from work today. I did some more searching and it looks like a few other people have had the same issue but just ran it anyway.
  10. I'm putting together 280zx struts with T3 coilover kit with dynalite calipers and 300z hubs for my 72 510. I have the coilover ring welded to the struts and the struts are cleaned up and painted. I mocked up the KYB insert and noticed that the gland nut does not fully tighten down to the strut tube, there is about 3/16" gap. That is without the washer installed that came with the insert, is it normal to have the gap? My car has 15" panasports rim that I will be using. I know that these will clear the dynalite calipers with the 300z hubs brake combo. And I read that 13" wheels will clear when you run stock 280zx hubs and calipers if you grind the little ears off the calipers. Is there a way to clear 13" rims with the 300z hub/dynalite combo? I'm following the dime quarterly strut build but with the T3 coil over kit. I might use the T3 camber/caster plates too because I would like to autocross my 510 and I like playing with suspension settings. Do I need to modify the KYB strut inserts to fit the camber/caster plates?
  11. I agree with this, have some long shelf life food and some water. Even if things dont get bad, people sometimes will just make things worse. The last place I want to be is at the grocery store if some freak out scenario causes everyone to panic. If something happens I can go straight home and hopefully wait it out. I have plenty to do at home, like working on getting my hood pins installed.

  13. Any info or link to the engine build? I would like to try a L16 drawthrough turbo with a single SU at some point
