Euro S Heads

Oh gotcha! I misunderstood then. When I was asking about whether or not the Euro heads had any advantage, I meant over the stock 5.0 heads. Basically the Euro heads are to allow you to use the existing computer and intake setup while still flowing enough for the 5.0 bottom end. I think we're on the same page now.

I have an '85 car, and I hadn't heard of people swapping the Euro heads for power before, so that's where I was coming from when I was asking.

i was told that the 89 928 i got from japan has higher hp then the US bro,.. is that true?

I wasn't concious that we were discussing this in Rich's profile thread. I copied this topic to forums.928oc.org/vbulletin/showthread.php?t=64 and will remove the posts from this thread.

Sorry Rich!

Not that I am aware of, I believe all post 1986 928s are the same performance levels throughout the world. www.928gt.com/t-928engine.aspx lists the hp of each motor.

the way the DOT mechanic explained it to me was that it was due to the emission requirements over there are less so it was not de-tuned as bad
guess it don't matter much. The first step is this exhaust i had built.



That nice spread will make easy access to the flywheel cover, reduce weight and allow for more flow for future mods. I was told this could be an extra 20hp.
The second add on is going to be that new air filter assm. I heard about.
I asked for the e-mail when its ready

You know there are X pipes out there that would be an improvement over the straight cross pipe, right?

The filter assembly looks nice, I think it is often used when motors have forced induction.
