    New Valves?

    Someone please correct if im wrong, but are stock guides not cast steel?

    New Valves?

    That makes two experienced engine builders on board with the bronze. Wish I had that info prior too... Ive only talked to Dave once but he was great over the phone and I really regret not working with him for my engine build. Live and learn.

    Make sure they use a bronze guide. Cast steel will cause gulling (sp? Might not be the correct term, but extreme wear from different expansion rates and metal on metal love). My guides were brand new cast, built by a reputable Canadian Datsun shop. Valves seized in the guides when the engine was warm. After more research apparently using bronze guides with stainless valves is a well known fact. SI valves seem to show this issue more prevalently. A well known L series builder in Australia gave me some advice afterwards about using these valves. He said excessive clearances or bronze guides are the only way to use these without issue.

    Just make Sure you have proper guides to go with those valves, or very large clearances within your stock guides. Was a costly mistake for me.

    Fuel Delivery - EFI Conversion?

    I don’t know the name but it was a high flow pump off of some 454 based vehicle. Super loud but did the job. When I went EFI, I tossed the surge tank idea out when I was running out of space in the back. My Walbro whispers in comparison to that Carter. Haven’t had any starvation issues using the drain out the bottom of the tank. I also haven’t been to an autox since the conversion.

    Fuel Delivery - EFI Conversion?

    The same pump couldn’t keep up with my modified L28. A $50 carter pump had no issues. Im now fuel injected and it’s come with a whole bother can of worms. In fact enough that I’ve barely driven the car over two summers (while not putting in a huge amount of effort).
  7. Take my opinion with a grain of salt. I’d take Tim’s advice seriously though. From my internet research most people including Tim who have used an aftermarket tubular header, experience cracking. This isn’t seen much in 4 cylinder applications, but the straight 6 is does. I don’t know Tim, but he is one of the few who have gone down the unknown path of high horsepower L series engines and I’m sure has a wealth of experience from failure.
  8. The euro L28et manifold has them. im no expert by any means, but isolsating the left 3 cylinder and the right (splitting flange in 2), and then putting something like the burns stainless double slip joint in the lowest portion of the big “U” for each side of the manifold.
  9. Well, pending where your RB is mounted within the bay, the stock L28ET manifold is rearward based. I haven’t mounted my manifold to the block to check clearances but you would think there would be room.
  10. Is there a reason why you have the turbo flange more biased to one side vs the Center of the manifold? Wouldn’t getting equal lengths be a little easier that way?
  11. Or they were cut, and used to raise it back up a bit.

    Another clunk post - ugh

    Your clunk sounds very much like my R200 clunk, and I’m running the stock shafts. Don’t give up so soon.
  13. Where are you located. I’m interested in the head. Hydraulic lifters?
