Recommended Posts

They look good Cam, HPC those babies......

Is any company manufacturing these or do we have to search for NOS items like these?

I had the extractors for my flathead Ford motor done with HPC and the temperature difference between standard cast manifolds and the HPC coated extractors was over 100 degrees!?! Just over 50 degrees external metal temp. :)

Ebay has them for $250 delivered, search the hi tech part number and comes up with patrol results. From hi tech they are $350.

Hi Cam,

Had a look for those extractors on eBay, here is a link to the 240k set, priced at $354.

The "HTH065" part number brought up 5 listings on eBay all with a different car/motor. The only extractor set for $250 is for a Nissan Patrol G60.......

Check out the link, you may need to contact the supplier to change your order.

On the hi tech headers website hth065 fits a few models of L6 motors but think you will find the common element between each of those models is the steering type. Recirculating ball steering which those headers have to clear. I got the pipes today and look just like Adams. Will update when I trial fit them.

Now you have me worried. They all have the same part number so I figured they must be the same. All priced the same through hi tech but cheaper through exhaust shops probably because they are 100 years old and praying for someone to buy them. Fingers crossed. Painted mine today, cant afford hpc coating yet.post-28990-14150829840701_thumb.jpg

Seems odd that the set you bought are $100 cheaper if they are the same as the others listed under that part number?

It runs and drives but no way I would take anyone in my family in it, needs brake work and has leaking valve stem seals.  Waiting till I get my own shed before starting on  that one.

Engine getting closer now, still waiting on a gasket set from amazon but have got it this far with stuff I already had. Going to run with the original 260z air fliter housing for now at least. Painted that in Chev orange which is not a very good match but looks good I think. Have been reading many posts on what kind of power to expect and don't know what to think. Some really low educated guesses and some high, then I look at Robello's mods and he can really squeeze some power out of these things.  Just hoping for a noticeable improvement, may dyno if I get really keen.

 

Mods are:

240K 83mm block

260Z crank

240 83mm pistons shaved 2.79mm

240 rods

Ported head E88 head ( by who?)

Not sure on  cam specs but looks to be about 280 duration? Moderate lift. Made by Camshaft engineering in Brisbane, no longer exist.

Dome top SU carbs

Removing belt driven fan for thermo.

Hi tech headers through 2 1/4 system

5spd manual

 

Any guesses?

No, that's why I didn't just rebuild the 260z engine. Combined the 240k with 260z so can still use original dipstick hole. That seemed to be the main issue, swapping sumps and pick-ups didn't look too bad but the dipstick looked more difficult. In using both motors I could machine the 240 pistons and use the longer rods to basically give me flat pistons instead of dished. Local parts guy has 240z's and said this was the mod back in the day to keep l24 engine numbers.

Just about done, not sure if the red cam cover and orange air filter cover go together. May end up running the brushed alloy cam cover instead, will see what it looks like in the car.

They look like early Z SU's with a 240z air cleaner.

I want to run the same setup on mine Cam. And you take some detail photos of the carbs and manifold? I think I'm missing bits

I can do that but not till Monday, motor is at work. I do remember they where the 3 bolt cap so this would be early 240z? E80 or E88 intake manifold.

I've got the early done top ones in 4 screw varient. Only minor differences. My manifold looks the same so hopefully will help me with mine 👍

Not sure which part you needed a pic of but here are a few. Let me know more details if needed. Also I haven't run this motor and carbs yet so house routing may not be correct.

First three are of my motor and next are from a z at a local car show, maybe helpful.
