The LZ9 MGB is finally running

[1988GTU]

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.

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.

[IsaacHayes]

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...

[robertisaar]

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?

[CNCguy]

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.

[IsaacHayes]

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?

[CNCguy]

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.
