Type 1 Upgrade

[Fldhse]

Considering upgrading my Type 1 Motor 2154 cc in my 57 356 Outlaw Coupe. Anyone know of an engine builder in the W. Pa. area. May swap motor with a polo motor. Already have 901 transmission and oil cooler, disc brakes. Anyone know of a mechanic or builder who has installed a Polo motor on the E. Coast.

We are considering the same for our '64 SC coupe. The Porsche engine is getting tired and a bored/stroke VW might be the answer. There must be somebody in the Western NY or PA area who is into hot VW's.

Another option is a T4 engine using a DTM fan shroud, a 914 2.0 is 100hp stock. My '67 bug I have T4 2600cc 180hp, 102mm Nickies, 78mm crank and mod T1 H-beam rods, cam, FI, etc with a 911 (901) and 914/4 gearing. I have 20K miles on this engine combo.
Engine about $10K in parts, say $18-20K pro built/installed. You can build a smaller 160hp 2276cc cheaper, but any bigger than 96mm iron cylinders you need Nickies.

I put almost the exact same engine with weber 44mm IDF's in a 356 flared kit, smokin' torque monster.
Not cheap but way less than a Polo.

The T1 vs T4 in a nutshell. Think small block vs big block.
T1 small block, way more parts, cheap performance parts (also lots of cheaper junk), can triple the power, 50 to 150hp* reliability with the right parts. Engine like a on/off switch, gets up to speed fast but not much torque at speed.
T4 big block, less parts available, more expensive, double the HP max 95 to 180hp*. Performance engine is torque monster at speed.

* Both can be made with more HP, the numbers I give are for reasonably longlife performance engines. Plus when hearing builders HP#'s claims keep in mind there's a lot of embellishment or shall we say "wishful thinking". Often builder AND client share equal blame with this wishful POV.

Does the engine bay or transmission connection easier with a T1 or T4? I am considering a T1 for simplicity sake and desire a little more kick than the stock SC motor.

The DTM kit and conversion flywheel bolts right up to a type one transmission.
The DTM turns the T4 into an upright fan, generator and fan used is type 1, it will fit a T4 engine anywhere a T1 engine will go.

Below is a 2056cc, 914 2.0 heads, CSP SS header, 40mm weber IDF's WEB camshaft, T1 pump, full flow oiling and the DTM is the fan shroud. About 130 HP maybe a bit more. Compared to the T1 it's a torque monster, this engine is going into a beetle.

If on low budget a stock type 4 can be used, with 914 2.0 heads and header still give you 100-110hp, stock and fairly bulletproof.
One year only the '76 912 used the T4 engine.
