Does the 5cyl have 38 or 40mm intakes? I thought that they were 38mm . More like the non GTI solid head engine. 8.5 engine-85- 88hp ish.
The spec line shows 38mm and the same specs as the 1.7 engine. And the throttle body is small along with a very small cam.
Allof my USA specs show 1.7 times 1.25. **Not the same as the GTI ** Actual power estimation should be about x 1.2- 1.23 with cam and ring loss.
The later and Canadian cars often had the 2.2+ engine .
The Canadian car had much better numbers for some reason. I had both at the same time The Northerncar had the 2.2, the USA car had the 2.1. The 2.2 ran much better.

*** Maybe the racers are trying to get weight for the US car and racing the Canadian car. ** That would never happen ... Just like the guy that won the ARRC in the Rocco with the Golf engine , marked it as Canadian spec , thus it was legal for a while .


Have funwith it,MM
