SC cams mod on a 930 motor?
 

I am rebuilding my stock 1980 930 engine. I was going to just rebuld it back stock but I was wondering if I will regret not installing SC cams. I want to keep the stock CIS and fuel delivery system for now (due to budget).

Are the SC cams with stock CIS worth it from a noticable low end performance upgrade? (I do have a k27 with a 1 bar spring as well.) Can you tune the CIS system enough to accept the SC cam? (fuel/air delivery, etc..)

Stay stock or upgrade to SC cams?

Thanks

Hi Millhaus,

I am going the same route now. I have been recommended to go for SC cams in my 930.
This will be noticable low end performance and drop around 5500 rpm as I understand.

There is alot of threads here explaining this.

Try this link. I documented this process when I did it a year or so ago.
The change to SC cams is well worth doing.

I have always thought the SC cams
were the best bang for the buck when it comes to stock 930 updates.

+1 :)

All my 3.2L engine has that isn't stock is SC cams, 930 jugs and slugs, and a single T60-1/0.85 AR turbo.

It has dyno'd from 427-447 wheel hp @ 1 bar.

Tippy,

Are you running an intercooler with that set up? Stock 930 or aftermarket?

Sounds awesome

Yes. Not sure of brand honestly. I bought the car this way from a friend. I have never looked or seen the brand of the IC.

SC cam vs 964
 

I have heard many talk about the SC cam upgrade as being the best bang for the buck on a 930 rebuild but others have mentioned the 964 cam.

Any opinions? What are the benefits of both?

Thanks

Running 964 cams, they pull much harder in the upper RPM range over the stock ones. Work well with cis or efi, a bit more aggressive than SC cams.
