Without going back to your original head and set up and only making only this one change it's impossible to know how much this is helping. One thing I would suggest is to increase the size of the hose and fittings from the manifold to the thermostat housing. The setup you currently have has 5 hoses coming in and one going out, all the same size. The hose between the manifold and thermostat housing is a restriction to flow. There are no guarantees it will help but it should maximize flow thru the system and improve cooling in the back of the head.

Woza, Thank you for making this happen! I have one question before I place my deposit. Does this kit retain the same maximum diameter of the azc kit? I have 15 inch wheels with very little clearance between the caliper and the inner side of the rim. Thanks! Ross

Maybe...BUT power is addictive and I bet he'll soon be wanting more. I would recommend getting a modern a turbo with room to grow.

I'm interested!

Cool experiment! Try covering your heat shield on the side facing your intake manifold. That will take full advantage of the material's emissivity. Also, take your temperature measurements on the same surface every time to avoid skewing the temperature readings.

It's interesting that DEI website for reflect-a-GOLD doesn't actually say it's gold or what it actually is made from. Polished gold has a very low emissivity and high resistance to oxidation so it doesn't radiate much heat BUT it's obviously expensive. I have a piece of their aluminum laminated glass cloth between my intake and exhaust manifold with the silver facing up towards the intake. The stuff works, there is virtually no radiant heat coming up.

Are you certain it's hitting the adapters? Are there c-clips on the ends of the splines to prevent the shaft from sliding in or out too far? Seems like there should be

The cam has been micropolished and is on it's way back to me. I'm planning to get a new set of lash pads too. Are aftermarket lash pads like the ones Motorsport Auto sell good or should I get OEM Nissan?

Isky said the cam is still good. They're going to polish it and ship it back to me. Also, they said it's not one of their re-grinds.

Lookin' good! I love the metal roof!

I believe the new rockers are forged too. It's just hard to see the parting lines since they are ground almost flat and the part is so dull it's hard to see fine details on it...and my crappy cell phone pics. These might help.

I believe it's normal due to the channels machined on the sides of the lash pad slot.

So I received new rockers from Courtesy Nissan. It's interesting to see the difference between these and the ones that came with my engine. The shiny ones are re-grinds that came with the engine. I'm not sure if they are the originals that came with the head but I suspect so. The new rockers are shaped slightly different. The top and bottom flanges of the I section are more rectangular and don't have the same definite top ridge as the re-grinds do.
