We have now gotten in yet another set of 310 HP cams for the
16v 928 - and I put them on eBay.

There are two listings - one for a set of Euro S "Big Valve" Heads and cams, and a separate listing for cams only.

I priced them cheap!

Enjoy!

I do not know if this'll work - but here is one link:

I have the euro non-s 16v. How would these effect performance?

Thanks

if only i had more money...............

Rob,

although the cams are part of what makes the 310 HP euro motor - they are not the whole deal.

add cams alone to your 224HP motor - my guess is 245 or so HP.
add the Euro heads too, now I think 280 HP.
add the Euro throttle body and intake - now you are at 310 HP.

approximations all - depending on the condition of your motor and fuel system. my numbers above are based on my experience nuilding up CIS K-Jetronic-fed motors. L-Jet would be different.

does that help?

Rob Roy

Thanks - that gives me a good idea

The euro motor also has higher compression pistons, does it not?
If so, I am guessing that has a significant effect as well...

As a euro owner, let me just say that you will probably still want more power.
Even s4 owners often want more power.
So if you are on a "quest for power",
maybe you ought to just save the $1000, and save another
few thousand, and get a supercharger...
Then you'll actually see power you can notice...

DANG - I didn't realize EURO cams and heads were so cheap.

I have a complete '85 EURO Engine with a TB/WP done 2 weeks before the 'donor car' was t-boned. It is for my track car project that is so far behind I am considering giving up on it.

$3500. Consider offers or interesting trades...

Very tempting....I wonder what it would do for my 4.5L US motor.

It is also good to keep in mind, that if you have cams and heads, designed to flow more, you really ought to get a euro intake and throttle body, and possibly headers, or s4 exhaust manifolds. Otherwise you might end up with restrictions. Not saying that it will make a giant difference, but if you are going to go for the euro upgrades, you might as well do all of them... Or just swap a euro engine into your car, or just buy one when one comes around... It just seems that when you do minor upgrades, one at a time, it takes a lot of time, and money, for small incremental horsepower increases. You'd probably do better to just find a totalled s4, and swap the whole engine... Or sell your s2, and get an s4... By the time you get that 220 hp engine to a 300 horsepower engine, I bet you will have spent as much as the difference between an s2 and an s4...

ive done just the intake and cams and got 242 at the rear wheels on a 4.7liter US L jet. (keeping all Ljet in place, and only adding a fuel reg)

putting the heads and using a 5 liter bottom end , we got 293 at the wheels.

Now, the valves are 45mm vs 43mm on the intake and the ports are larger on the heads.

dont think compression is all that important, especially, since we did get 242 at the wheels on a old, 150,000mile 4.7 US and compression of 120psi per cylinder (rated at 9.3:1)

BTW, we also did just the intake on a 4.5 US 1982, and got 218hp at the wheels. (no cams or heads, just intake runners and TB on the stock AFM Ljet)

bcdavis

But do you think the intake would be a restriction, if someone put just the cams on a US car, without the euro intake?

Carl Fausett

BCDavis and Mark K:

...but both of you guys assume that Rob is talking about a 4.7 liter motor.

I assumed he was talking about a 4.5 liter.

There, I have found the Heads and cams make more of a difference. Frankly, after I supercharged my 78 4.5Liter motor.... I later got a Euro throttle body and intake system from a donor motor and did not realize an increase at all on the dyno from installing them.

It just proved that the blower makes up for a lot of restrictions...

For a non-boosted motor, I think the 4.5 Liter owner would be pleased with the Euro heads and cams upgrade. Very reliable performance.

If anyone is serious about spending money on a Euro S setup. I have all the top end components, currently on a 5 liter bottom end. I have to pull the motor to identify and resolve the issue, but that project would move higher on my list if someone really wanted the euro S heads, cams and intake. The top end is from an early Euro S, so based on 300 not 310 hp.

The bottom end is a 5 liter from an '85 with the pistons notched for the big valve Euro S heads. The bottom end has an issue. I would be happy to consider selling the top parts only, or fixing the bottom end, and including that as well.

I just bought a complete running '86.5 928 S car to use it's motor until I complete the S4 motor build. Of course if I can sell enough stuff, I would pass on the rest of this season to have the S4 motor (including 968 pistons) ready for next season.

If anyone wants an S4 suspension, I will be selling that off the '86.5 very shortly as well.

The cams are gone.

Cap'n, you have a PM.

Thanks 2v4v!

Dozman - tell me what your friend is looking for. If I don't have it, I can probably get it if he can wait a bit.

We have developed a relationship now with several "breakers" in several differnet countries and we are importing these parts to the US for you guys. True Euro 310 HP heads, cams, throttle bodies and intake manifolds are so scarce in the USA that I have all but given up looking for them here.

I go overseas and buy them, but shipping charges are high and it takes a while to get them here. (My last shippment from Great Britain sat in customs for a week while they inspected it.)

We do have one matched set of Euro heads and cams still on the shelf from my last shippment. Very good used condition. Trying to sell them as a set - but if someone wants just the heads or just the cams - let me know.

Sounds like Stan Shaw would sell his too.... so there is two sets....

I love to keep the early cars competitive and on the streets!
