'72 914 Power train swap, Removing V8, installing a .... Options

[jb6000]

Right now this car is a running 1972 914 with a 901 trans converted side shift, and a 350 SBC V8.


Salvage title car, registered etc. Calif.
BMW 320 calipers up front. Renegade conversion.

So there are many engines that work good in a 914.

The stock 914 4 cyl is about 180 pounds. (I am not sure if that is bare long block or dressed motor complete.)

The iron V8 with iron heads is about 525 pounds complete.

I have a motor that is a 4 cyl. that is 225 pounds long block and about 330 pounds dressed with a turbo.

It can put out 300-500 hp with equally high torque.
I have a 6 spd transaxle that adds a bit of weight but is far better.

So why is this 1.8 liter engine so much stronger than the original Porsche 914 1.8 liter engine?

The picture on the top is the naturally aspirated 914 head, the picture below that is the new engine's with a turbo force fed head. Yamaha was in on the creation of this head.

"An engine's power is limited by how much air can flow in and out of it."
Roughly quoted from some smart guy.

This engine has more valves than the Chevy V8.
