Cam, Advice on #73 Options

[914_teener]

I have zero experience with that cam Dave. My comment was meant as a pun/ joke about the grind No.73. In California if you have a 73 you don't have to pass an emissions test.

With that said:

It depends on what you want to do. What are you trying to achieve by changing the cam using stock d-jet? Just curious.

Sorry I missed the pun Teener. Yes stock DJet.

The reason I am changing the cam is that the old one is worn. I read that the stock cam was very inefficient so I was looking for an alternative, I wanted a Rabby 9550 (I think that's the one) but they don't seem to be available.

Anyhow I got fed up with all the different opinions some say the Webcam #73 is good others that it will never work. I saw a stock NOS cam with lifters on the Samba so I bought that.

I believe 9590 is the replacement for the 9550 cam from Type 4 store....it's supposed to have some
improvements made to it from the 9550.

You mean this one

It would cost another 25% import tax to bring it into Sweden, I dont think its worth it for a stock car (for me that is)

That's the one. They only sell the kits now.....it is a bit pricey, especially when shipping to Sweden!

For what it's worth, European Motorworks in Hawthorne, CA have a stock grind cam. I used one in my 2.0L rebuild last year and it seems pretty good so far. I don't know if it's exactly the same as a stock Porsche cam or not but it's an option. I bought lifters from them as well....
I did purchase the 9590 kit for my 2056 build but I'm not anywhere near done with it yet.

No worries about the pun or opinions...everyone's got one.... so here is another. (IMG:style_emoticons/default/laugh.gif)

I have been looking reading and talking about cam's for these motors for quite sometime as well. I haven't done anything about it as yet- I am still working on a replacement trans, so no time and money for the motor right now.

I don't think the stock cam is inefficient....just optimized for the hard mapped VE curve that D-jet provides, if that is what you are going to use for induction.

If you change the cam and or other things, you will change the VE curve on the motor as you may know already.

I know Raby's stuff is pricy....absolutely no affiliation....but as far as I know, he has done lots of dyno work, that is worth something.

I don't think you can go wrong with the stock setup...just expect what the stock specifications already show...Net 80 BHP or so at the wheels.

Expect also a reliable motor given a good meticulous build and decent gas mileage with the stock set up. I like the "set and forget" reliability that the good ole d-jet provides. It can be tweeked to a new interpolation with a different cam ect. as others have done.

If it's me...I don't mind paying for that experience. Do it once and no regrets. It's hard to weed out all the opinions for sure. Dyno time and results are proof in my book.

In My Humble Opinion.

Others may vary.
