It looks terrible... Look at the miata..... UGLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and a woman's car.

Put a H or X pipe and it should sound better.

So details, variable intake: functional or or not? If not maybe try the 3500VVT upper instead...

VVT? disabled and locked? Or gen3 cam setup?

Womans car is fine with me as I have no doubt about my manhood.

even though thats a very good point, you'll never see me driving/riding anything pink..... or a miata......... hell is a pink miata: i finally understand the meaning of life.

I really am not too worried about the sound at this point. If anything I want it really quiet. No need to attract attention.

I am basically running a GEN-III cam setup and have not experimented with the variable intake yet. There is an LZ4 plenum sitting here to do some comparisons with.

So is the gen3 to gen4 cam swap kit ready? What is involved for swapping it in? Any machine work? The H/X pipe might make it quieter...

WILL make it quieter...

and whats this about a gen3/4 cam swap? a 3 cam in a 4 block or a 4 cam in a 3 block?

There are a few LZs being built using the cam bearing spacers. We ran a small batch of spacers several months back. With the spacers, you can use a GEN-III cam and TC setup.

Does the gen3 timing cover fit the gen4 and match up with all the coolant ports?
So all is needed is the cam bearing spacers and you can throw in a gen3 cam? I don't see them listed on your site. What holds the spacers from moving?

There is an outer shell that a stock GEN-III bearing fits in. Then the assembly presses in like a standard bearing. In the end they are like thick walled bearings. I haven't added them to the store yet.

The older covers will bolt to the block.... BUT... you still have the issue of the coolant return system since the LZs have U-flow cooling. I have a couple of ideas but haven't done anything with them yet. As I always say... time and money.
