Kickbutt Street/Compeditive Track/Canyon Road Dream Car!

I"m not sure what a bus core engine is worth ($100-$300 depending no condition) the used webbers should be about the same, again it dedends on the condition. The bus heads will need extensive rework to use on the street/track engine you are looking for. You might be better off finding some 1.8L or 2L 914 heads. You should call Head Flow Masters and get their advice on the heads and send the heads(either the bus or 914) to them for the work. If you are looking to build a street/track turbo engine, don't look to use alot of stuff other than the case from the core engine. The pistons/cylinders will have to be top self (JE/L&N) head work from Head Flow Masters or Ham Inc. a good turbo grind cam from Web Cam and I would go with L&N ceramic lifters after some of the stories I have heard and seen with type 4 lifters in the past year. As for the turbo set-up I don't have any real info on that. Don't sink alot of money in the core engine if you aren't going to use much of the stuff from it. And when you are done the webbers might be too small, If you are going to turbo it you will need 1 big carb or an FI set-up.
As far as the car,,,I agree with the "Loose the square lights and whale tail" comments. Or get the Yahn Hammer cd with the Miami Vice theme song to bast as you drive down the strip.

The stock cylinders arn't any good even for low boost? (only lookin at 150-200HP here. I actually don't want to exceed 200HP. Not looking for a Super Tranny for the Super Beetle, although to recognise a perf. tranny is good and more then likely needed. I know where to find some stock (or close to it) parts (pelicanparts) but no idea where to find other parts.

I'm interested in Turbo as I can assemble it myself (also I've found no kit) and potentually save some beans as your just makeing the engine more efficent (100% + VE is possible with turbo, although it does generate more heat)

Can I overbore the cylinders? or do I have to buy new ones?

[NO_H2O]

You can bore the 94's to 96's but that still leaves you with buying pistons. Then you will want to turn up the boost and the iron jugs won't shed the heat like Nickies will (Nickies were the standard on Porsche 6 cyl engines from the 70's on and all turbo cars). I think that if I were planning a turbo engine, I would plan on useing Nickies. I spent a year with a bad combo(wrong cam) that ran hot on the hwy(non turbo). It is a bad feeling, always watching the guages and wondering if this will be it's last trip out.

Well I could always just hone (can I do that with these?) and clean up the stock cylinders, get some hypernumatic or forged pistons, mich the crank (can you do that with these too?) and slap a turbo on it. If it'd be better. (I can compensate for the smaller pistons with alittle more boost


Does anyone know anything about these cylinder heads?

I'd prob want the level 3's..
$699.95
45 X 38mm Valves. These have more extensive porting and larger valves compared to the Level 2 heads, and shows that you are more serious about your motor and performance! Street engines with 94 bore size around 2.0L displacement will have around 165 Hp with these heads, when you have 44 or 48mm carbs.

I wonder how much low torque there is with this setup?

[Supa Ninja]

That $699.99 price tag is per head. I'd go stage 2 on a turbo engine, and spend more on a nice set of connecting rods.

At this point all I can offer you is a couple links for you to get information.

I guess you could hone the 94 jugs if they are srait to start with. If you "Make up for it" and add boost you will add heat that the iron jugs may not be able to get rid of, but I already said that (said lots of other stuff too). With out a proven combo you could spend lots of money only to find out that it will not cool or run right at all. Do your home work and get the right combo. I have never built a turbo air-cooled but I have seen a couple of small type 1 combo's that ended up scrapped because the "turbo kit" was not supported after the sale and the suggested combo was all wrong. First you need to know the little tricks of an air cooled engine and a type 4 inparticular. If you have never built an air-cooled engine, I don't think a performance type 4 turbo engine is one you need to start with. You have asked for advice in many areas of engine work, that leads me to believe that you don't have alot of experience or knowledge when it comes to these engines. They are not like the radiator laden engines you have tinkered with in the past. That is why I directed you to Jake. You may end up throwing good money after bad trying to make a bad combo work or you can let a leader in the feild give you a turn-key combo that will work and give you years of service. That is what a resposible moderator should do. There are 1 mabey 2 other reputable type 4 builders that I could recomend and a few that I would not recomend to anyone. One thing that I would not do is start on an engine like this with little to no experience or with out the guidance of someone that I know has the experience.
Thats all I can do is try to give you the best guidance I can. And I have. My work here is done.

Price is per head?? Where does it say that? Is that how it works with aircooleds?

Thank you for you assistance. I've added up several times the costs of doing this. And one of Jakes kits just might be in order. Unless I can find a "proven" cheaper moter that does what I want. That is difficult..

[Mysticle31]

Are there any good Type 4 tuners here on the west cost? (What about Type 1 tuners?)
