Engine rebuild, a few questions Options

[stugray]

I have rebuilt a type IV a couple of times, but I was young & naive.
This will be a 2.0L with stock FI for vintage racing.

1 - How do I hook up the stock fuel pump line(s) to a fuel cell?

2 - are there any Cams other than the stock one that will give me increased performance while still using the stock FI?

3 - What compression ratio should I target? I am working that step right now - CC'ing the heads & setting the deck height.

4 - The CAM thrust bearing has just one side with the thrust plate on it. If I recall, when I upgraded my last 914, the guy at the performance shop gave me TWO with the thrust bearing on it (one for each side). Should I be looking for those?

5 - After splitting the case, there were 2 or 3 "bumps" that needed a little "flattening out" with a file. Can the case be damaged by trying to clean up the nasty spots, or is there a way for me to make sure to get it right?

I imagine that the only thing I could do would be to remove all the studs and rub each side over some sandpaper taped down to a very flat surface...

Any help is appreciated.

2 - I looked at the Raby website and it looks like I can only get a cam if I buy the whole $500 package. I am tempted, but if I blow that kind of dough (in addition to all the other stuff I need) right now, I wont be on the track for another year.

Understand this:
My package INCLUDES ALL the items that are necessary to outfit an engine with a performance camshaft. These are the things that IF you purchased a camshaft elsewhere you'd have to buy separately, or you'd not apply and the engine would be compromised.

View my camshaft presentation to understand exactly what compatibility means.

You will see that this money is either spent now or later, generally more is spent later when you experience a failure or have too much lift for certain valve springs and etc.

With my package I ONLY sell the entire unit, so unless someone doesn't install the components it is impossible to have incompatibility.

If I just knew the lift & duration of an "improved cam", I could have one made myself locally

Exactly and thats why my proprietary information is not posted anywhere. I spend 6 figures a year + developing my components and I don't make it easy to steal on purpose.

BUT you may **think** its just that easy, grabbing some numbers and having a cam ground, but it isn't.. How is that camshaft going to work with your port margins and flow? Whats the ramp speed of that lobe? Is it too fast for a lifter of .943 diameter? How will it idle? What vacuum signature will it have? Will it produce power above or below the target RPM range that your gearing and rear tire size optimizes with?

My valvetrain kit doesn't just give you parts, you fill out an extensive questionnaire that interviews you and your project engine, then I select the camshaft of mine that works best for you based on the numbers and my direct experience and practical application. None of this is expensive, its priceless.
