i remember seeing an advertisement in a roudel issue a few months back. I dont have any here at school so i cant look for you, but it was there. It wasn't a big player, some specialty shop. I'm sure you can check the list of advertisers online.

If you are talking about the M20 one then its completely useless

[bpmack16]

why ??????????????

[Erick]

because the intake manifold is restricted.

because the intake manifold is restricted.

yeh its restricted by the throttle body;)

he meant to say the intake manifold is the restrictive point, or bottle neck.

The AFM is also a chokepoint to address.

Don't waste your money.

didn't you notice the ;) in my post.

You'll get more from a modded head than a modded intake manifold or BBTB. So i say the head is more important than both put together. But a BBTB or modified intake manifold shouldn't be purchased unless you have a properly modded head with good cam and extractors IMO.

IMO, u guys r wrong...

Of course modding the head u gonna get power, but u gonna gain even more if u port the intake manifold, and use a BBTB... u gonna have gains.

What we do here, is take a TB butterfly from a M30B35, dissasemble the TB, so it's just the housing... take it 2 an engineer, and tell them to bore out the TB, to work with this Butterfly... Works pretty well... ;)

We all use them...

SAE30 you know as well as anyoine that a good head (and cam) is better than a BBTB and a ported Intake manifold but one cost more than the other
