yup , all euro goodies.

BRB-83-911SC

I have the heads off my 84 Euro at the moment, and the numbers are: 928.104.348 3R, and the valves measure 40mm for exhaust, and 45mm for intake. So, the 3R heads are for the 84-86 Euro S (310hp) and the 2R heads are for the pre-84 Euro S (300hp)? Maybe this will help....or confuse.

Now I have to dig out my Euro non-S head, cams, and towers to see what I have.

Does anyone have a list of parts and expected sizes and such?

Ducman82

you could always buy this stuff and compare... you know.. all hands on and stuff...

brutus

Comparison is 220 HP vs 300 HP ! that is about all you need to know

Pretty sure both S and S2 heads are the same, but maybe some weird passages are different?

Euro S heads I believe not only have larger valves, but larger better shaped ports.

brutus

right ports are bigger to work with the larger intake runners.

even with a US intake system, you would still get some much needed power if you bolt this stuff on.

Please bear with some newbie questions regarding this. From what I'm reading, if I bolt this on to my US 82 (non-competition package) AT, I could see HP gains approaching 80 HP? What would the HP gain be if I just bought the cams? Combined with better flowing exhaust, I could potentially increase my engine's output by 100 HP, correct?

I don't think I'm ready to purchase this yet, since I'm no where near ready to pull the engine. Are Euro heads particularly rare?

I'm only asking because as much as I love my car stock, I was researching ways to give it more power and the options seem limited. This seems to be a (relatively) easy way to gain a significant increase in power. Thanks for your patience.

you could add the cams, and get some HP increase, but its really the package of cams/heads that see the HP bump. better exhaust with this set up would add a good amount of bump to that baby

You won't get a 100hp. I did my exhaust and that got me to 203rwhp on a 4.5l. Euro cams got me to 223rwhp. My guess is if I had euro heads and intake I would be at 250rwhp. I know the car would scream with this setup.

How much for the heads?

Ducman82

id like to sell as a complete package for some one, but heads id like 1k ish obo

Someone needs to grab these, this is a pretty good deal.

Only thing I have to trade is my spare G28/08 with LSD.

I put these heads/cams on my US 84. The car has headers and a 3" exhaust. It made 272whp. Assuming driveline loss is 15%, that puts crank horsepower at 320hp. So yes, these parts with a good exhaust, and a correctly running car, can gain you nearly 100hp.
