Just checked webcamshafts website and I think the valve lift of the 86a is too small (11.05mm). Turbo's love valve lift is my current experience.
There's probably a reason Webcam advertises their 119 as a turbo cam...
I would advise to change the cam to one with about half an inch lift (12,7mm)
1.7mm lift difference is A LOT!

Just my 0.02 cents worth of friendly advise :rolleyes:

Youīre right about turbos loving high lift,I might trade it in for my original choice the webcam 163.I havenīt really decided yet.I like the 86a because itīs a "quiet" cam and easy on the valve train and still pull to 7K.As you know choosing the right cam is always a challenge.What doesnīt make it any easier is following your experiences and seeing and driving with Arminīs 2 liter turbo with a low (11 mm) cam and the performance that his engine has.Itīs actually not that spectacular riding in Arminīs turbo and you think at first itīs kind of a pooch,then you glance over at the speedo and youīre doing 260K/mh.His car doesnīt have the snap or agressivenesse that we see with the type 1s i.e. 2276 or so.But itīs just incredibly fast.Itīs a ticket magnet...

A very small update: The CU heads are back from glasbead blasting.To my surprise,they are in much better shape than I thought! Today they are getting shipped off for porting,seats,valves etc.

Another small update.The case work is finished.The mains had to spindled out to 0.50mm.Now I will clean the case up a little better and then install the Raceware headstuds.

Good progress!
What are those weird looking copper-coloured thingys sticking out from under the bores?

Oil squirters to cool the pistons.Simple but effective;)

Wally December 18th 2009 08:14

Thought so, but how are those fixated? Mine sit much higer up and into the bearing saddle.

70Turbobug December 19th 2009 07:28

The saddle is tapped and the squirters are screwed in.The squirters are the tips from a wire welder.Iīve seen others use grease nipples/fittings aswell.

Xellex December 19th 2009 07:45

guys, what size do you think is best for the hole in the squirters? And do you have a closer look picture of them?

70Turbobug December 19th 2009 11:27

There are different options.My case uses the tips from a wire welder with an M5 thread.Location and angle are the key to make it work properly,though.

Wally December 19th 2009 15:05

Xellex,
I use the squirters from a 911 turbo. Those also have a check valve inside so your oil pressure doesn't drop at (hot) idle. They open at 2 bar or there about ;)

Mark,
Did Remmele install these for you?

Tnx,
Walter

No, Remmele uses the Porsche squirters also IIRC;) Most of his engines do not have oil squirters.Armin did the casework - itīs one of his cases I bought from him.I gave him my case as a "trade in".So he deserves the merit on this :D

Another small update - my billet single stage dry sump pump from Thorsten Pieper came in.It has a 3 piece housing with 32mm gears.
