it'* my underdtanding that the best flowing manifold for a turbo application is actually a gutted M-62.

What is a M-62?

a supercharger. you remove the screws and replace the snout with a block off plate.

Can/ will it fit on and L26?

No. He'* lost his vendor status for some very good reasons. He hadn't posted on the Forum for over a year, or updated his website for over two years. His rockers are almost twice as expensive as the alternative, and there are other reasons as well.

Mike, a Miata Cat? Is it rated for the flow of a 3800? What size Miata motor?

1.6, the cat cat with a super charger kit. Bad idea?

Ummm....I think a drinking straw or two might do you better.

No cat for a 1.6 liter motor (even supercharged) is going to flow what you need.

So I will replace today, it seedem to do well, But I am sure your knowledge is better then. 'Hey that fits, lets try it.". What about fuel system on this cars, they work well under boost? The L26 I am asking on. I have a fuel pressure regulator that rasies pressure as booost rises. Just an idea?

There are some very good Magnaflow cats available for around $50 new available for our cars. You will want to consider one of them if you really plan on flowing more through that motor.

Here'* one that we know works well for your car:
Magnaflow #91006
