I am running the pauter rockers on mine understanding full well the limitations of the luberication system. In my application they will not likly get the chance to wear out and the little bit of extra ratio should help the cam compensate for marginal valve sizing as well. Or so goes the theory anyhow.

Nobody has complained about the 21158 BAS header, only the smaller 21152 system. Oliver says they still require "fitting" though. http://www.ahnendorp.com/beetle1.html

<B>If you listen to Jake (always a good choice) the 86b/86c cam should have high compression, 9-something. If you keep compression high you will have enough low end torque to satisfy anyone but deisel truck drivers. There is enough duration to keep power nice up high. Bigger than I would have gone with 2600cc, especially if I have been unhappy with low RPM performance before.
Some have complained that the BAS exhaust system was not easily tunable, and prefer to use either a custom exhaust or a European Motorworks header (in California, oddly, not in Europe). I think 1 7/8" is pushing it, but then again, with the bigger 86b/86c cam you might be right on the money.
This thing will drive entirely different from your smaller, higher revving 2054. Be prepared. I hope your tranny is too. You'll want tall gears to take advantage of it.

Rockers from a 2.0 (at least a 2.0 914) will not accept 911 swivel-foot adjusters--the threaded hole is too large. All the 1.8 914s have the same large adjusters. The pre-73 rocker arms have the smaller adjusters, and those rocker arms will fit the 911 swivel-foot adjusters.
On the non-914 Type IVs, I do not know when the larger adjusters came in.
You will have to modify the rocker arms, and quite probably shim the rocker stands and maybe even change the length of the pushrods.

I think the 10mm tappet screws came in on the 1.8 solids first and all hydraulics in the bus . I have never seen them in the 411/412 series. Those never ran hydraulics and used the 8mm on the 1.8 in 74. Ray

If you want 911 adjusters you gotta have 1.7 rockers.....I have some and will be selling these ready to bolt on with my spacer kit and H/D bolt kit as well.

Some more questions...
About rockers and shafts ? are stock good enough or shall i use billet or somthing...?
Will original work with dual springs or will they be a week point ?
I have the rockers from 2,0 L 914 and I have heard that 1,8 is better when using swivel feet adjusters from porsche 911.. any ideas ?

Re: 200hp Type 4 engine.
Hi.
I'm curious to know how many builds have since been made and how have they performed through the years. I'm on the same path/trail of thought and was seeking advice on which route would best meet my desired destination.

Re: 200hp Type 4 engine.
Ah, man.. Seeing these old posts take me back.
This forum was the best of the best.
Most of these guys went on to Facebook, got out of the hobby or died.
Or even worse, converted to Subaru!
To answer your question...
A lot of us went on to build different type 4 engines.
When built correctly, depending upon how much you drive your old car, they can last literally a lifetime.
Because Jake did the most real research on different combos,
And sent out engines to customers to be run like a customer runs 'em,
His combinations tend to be the most proven,
And therefore, most who build for real longevity follow his example.
You can glean info from type4store.com..
Like a with type 1, building a serious engine with increased displacement requires you ditch the stock heat exchangers.
Gas heater, no heat, or fab some heaters onto a header.
For this reason, proper large engines are rare.
Still, though,
Done correctly,
You'll only take it apart because you want to change something.
