i picked up a S3 long block, but decided to go another route for a motor to play with. Cams are from a M28/44 motor 85-86. clean, no rust. coated in assembly lube and wrapped up for storage. 300 OBO plus shipping.
heads are up fro grabs too (bent valves/TB fail motor)

 

I want them (cams). Can you confirm quote to shipping to Finland, Europe?

 

PM sent

 

Just so that all are aware, these will not bolt straight into a S4 or later 928 head.
The cam shoulder doesn't work on the 5/8 exhaust cam

 

It can be modified by a machine shop to work. I'm running an S3 grind in my GT for the left exhaust.

 

I know the exhausts are more desirable, but I could use a pair of S3 intake cams for a science experiment.

 

Anyone interested in S4 cams please PM me.

 

How much of an HP gain would one see versus stock if these were machined to fit in an 87 s4?

 

Same as GT cams. So 10 hp

 

Changing cams is a lot of work , why would you not go with a set of Colins cams ?
I pulled out the GT cams , installed Colins triflows and a exhaust system and picked up over 60 HP

 

If I had to guess why someone wouldn't go with Colin's cams it would probably be due to them costing around $4-5,000.

But damn they are nice!

 

Can I have your driver's side exh cam please? I'll happily give up my ground S3 cam or whatever.

 

Tri flow? Where is the third one flowing to?

 

If I ever parted with the GT cams It would be as a set , I will never put them back in , the car runs so nicely now , but I just like to keep all the original bits . TRIFLOW = stagered intake lobes , one valve opens sooner and one closes later , it maintains better air flow , resulting in better mid range without effecting top end . I also have 2 sets of S4 cams / a set of threshie race cam ( probable junk) and a extra set of Colins TRIFLOW cams . And a set of 16v highlift new from billet cams with matching heads fully ported big valves ect

 

If you do get rid of the GT cams as a set, keep me in mind.
