Turbo valve cover modification for installation in a 6, Anybody done it? Options

[bdstone914]

I have a customer who wants to add billet lower valve covers to a 6 conversion. He had one machine shop botch the first pair. Anybody done this and know how much material needs to be removed to clear the suspension point? I drawing showing the area to machined and the finished thickness would be ideal.

Please pm me if you can help

Turbo covers are heavy, you likely could take the fins right off. Mine are also shaved down to the top of the stud bosses, about 1/4" of fin left.

Mmmmmm..... twin plug !
Is it difficult to remove the #2 plug connector ?

I just tried it (IMG:style_emoticons/default/wink.gif)
It's tight, you have to sneak it out, but I didn't have to force it

Yea but my point was that you mill the fins off and that's half of the reason gone to buy them.
Dirt cheap (IMG:style_emoticons/default/idea.gif) my pricing came back as up to $230 each new or $200-300 used hardly dirt cheap,but they used to be.
Personally I would rather speed the money on a good set of engine compartment seals and keep my engine clean underneath than spend this kind of money,there are a lot of good aftermarket gaskets out there to sort this issue with the stock covers also.
Fairs fair but your comparison between between a T1 and a 911 isn't really valid,the 911 motor in a 914 needs all the cooling it can get and generates a lot of oil temp.

Well I admit I haven't needed to buy parts for almost 3 years and I know in that time prices have exploded, but you used to see good used SC covers on the bird for $30-40 a pair. The SC cover looks just like the early mag covers but are heavier and made out of aluminum.
As far as the type one comparison, IMHO is a good comparison it's aircooled and in high performance trim they have all kinds of heat issues. It's all about surface area and air flow, do you really think 4 little fins in a hot area is going to make a huge difference? My 2.0 berg engine running 8 quarts of oil and the added surface area of the sump still over heated, till I put 2" standoffs on the decklid increasing airflow. Oil has a real piss poor heat transfer rate.
The only way fins on the cover will make a noticeable difference is if each cover has ten 3" fins. BTW this as been done by a guy on the bird.
To me good engine seals, etc., is super important on all aircooleds so I totally agree with that statement.
Airflow, engine seals, proper tune and/or a cooler will do way more than a couple of little fins.
