I've had the opposite luck with BBQ paint. What brand did you use?

Re: Remembering Art Hughes

Just heard about Art. Sad news for sure. I'm glad to have known him and I'm not sure if it was him or I who talked the other's ear off about Datsuns. A wealth of knowledge and one of the few true die hard fans. Art was always happy to pass on his knowledge and answer every question. We spent a lot o...

Re: Byron's 1968 L13-3 on the Tree L510

Last Friday I took pleasure in assembling the new unit, aside for the obvious new paint, all seals were also replaced. On the room air flap, I initially placed a layer of 3/8X1/8” thick foam rubber tape around the perimeter, but I needed to double this up to make the right installed height for a go...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Picking away at the endless "little things" while I try to get the head studs squared away. Did some more porting and polishing on the exhaust manifold. I already matched the ports but I wanted to transistion and take some of the roughness of the casting out and round off any sharp edges going into ...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Id love to see a better inlet manifold for the Z head I feel the inlet for the first port number 1 to be restricted otherwise a really lovely build ingenious use of KA manifold I may build a custom intake plenum and runners down the road for this but for now the stock 200SX bolts on and I've ported...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Well Ron I appreciate the kind words but I don't think I'm the guy you were thinking about which probably makes more sense about me being an SR guy :) On that note I would love to do an SR swap but they are pricey and I like the adventure of the build. I think the Z22 will be a capable engine and it...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

So apparently when I was told to use the L20b ARP set on the Z22 the person was assuming I was building a LZ. The L20B studs are WAY too long for the Z22 with the stock head and they don't make a Z22 kit (or any NAPS Z kits for that matter). I think I've found a stud that will work. ARP sells these ...

Re: A 510 30 years in planing.

Did you try bypassing the electronic boost controller to see if it's causing the problem (eg opening the waste gate too soon?). The GFB recirc is mechanically controlled. You set what percentage you want to recirc and the balance to blow off. The Turbo Fuse is a simple mechanical device - it's a bac...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Hey good to know about the Kinugawa - never even made the radar. I'll check it out for sure. Might even be decent for the L28ET :) I've got a GT35R for one of them but like I said I've got lots of projects on the go ;)

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

I hadn't planned on it. I'll be starting off running 7 psi with a T3 and won't likely run over 12 with that turbo as it really starts to fall off it's map. I've got lots of other builds so I wasn't planning on buying a T28 or something more suited for the engine. I am, however, curious as to how an ...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Fixed the last valve seat with the nick in it. All the valve springs and valves are re-installed. Spark plugs gaped and semi-indexed (picked the best of for the eight). Painted the head with high temp exhaust manifold paint to match the block. Ready for cam reinstall. The hot cam for the L28ET is th...

Re: A 510 30 years in planing.

You're running an electronic boost controller? If so I would tend to think it was possibly the configuration of said boost controller. Have you tried bypassing it and just running off the spring/vacuum setup? I guess you need to determine if something (vacuum leak to the wastegate, electronic valve,...

Re: A 510 30 years in planing.

I bet you'd be happier with a T28 based disco potato style turbo (GT2871r I think). Should build boost quicker, though ultimately not as much boost as the 3071. Listening to the wisdom of others, a non-log-style true header style manifold will also build boost quicker if properly constructed (I kno...

Re: 1969 Datsun 510 2Dr Z22 turbo EFI build

Pretty much done with the head now. Lapped the valves in and hot tanked the head. There's one seat that has a nick in it we'll try to polish out then a quick clean and install the valves and cam. Had the old piston wrist pins pressed out and the new pistons and wrist pins installed. Sent that to the...
