Turbo Type 1? Which base engine?

[Mysticle31]

I've recently been thinking to the posibility of a Turbo type 1. I think that would be way fun. And work well.

What makes a good starting point. I was looking at shop talk forums and people are running stock all the way to 2217! I read somewhere that turbos like shorter strokes (or was it longer strokes I don't remember). I'm interested in making power everywhere! So a smaller turbo may be good, that way I could make boost waaaay low. I do NOT want to exceed the 200HP mark in any way shape or forum. I dont want to spend thousands and thousands and thousands of dollars on a Super Tranny for my Super Beetle. Although I do recognise that a perf. tranny is required/recomended.

This is a steet driven car, want gobs of low end torue and to pull like a scaled rabbit to *whatever deemed sane/built for per $ spent* rpm. The car is 0034% Drag, 20% Road Race/Twisty Canyon road, 80% Street. I'm willing to go and check out the engine every week or two. (Valves, keep an eye on it..) I don't want to worry about taking long trips in it (obviously, I would check it first). Nor do I want to pull it every week. How do I deal with heat built up by a turbo engine? Ovbiously the engine is WAY more efficient but that still creates a little more heat?

1915 is a common choice.

I'm also wondering about these engines being able to cruse maximum 80-90 mph all day. And be on and off power all day should I be driving a nice twisty road, or on a race cource. All without overheating.

as nice as a 1915 sounds, wouldnt it be better if it were a stroker to add more low end torque to make up for the turbo lag?

I think the logic with short stroke is the turbo will spool up quicker. Quicker spool up= less lag. The quicker the rpm's the more exhaust to the turbo. I wonder how a 1.8L with it's 93mm bore and 66mm stroke would do as a turbo engine.
I think a stroker turbo would work too. There would be more bottom end but it take a little more time to spool up the turbo. On a side note the exotic turbos with stuff like bearings and Ti spools have less lag.

The deal is alittle sweetned as the car I am looking to get can come with a core longblock type 4 2.0L from a late bus with Webber 44 carbs and manifolds. All would have to be rebuilt. Uh oh, there's been some question as to weather or not it's two liter. The paper he copied from some VW book in the 80s sais it's a 2 Liter, but on a great type 4 website sais it's a 1.8!?

Where can I find parts to rebuild a type 4? and build it for boost, or build it for NA HP. IE Cylinders, Perf cams, exhausts that will work on beetle, cooling for it, alts, cranks, rods, rockers, headwork...etc.
Can I use any type 1 stuff?
