How about this engine?

[Jocke]

I looked at an engine yesterday it was an old 2.0liters engine with 2.4l pistons and a CIS injection for it and one Turbo "Garret T25"

Are anyone have a clue about the power this engine can deliver?
Itīs build for 1bar pressure.

Havenīt anyone seen this kind of building on a 911 engine??

I thougt there must be someone who has done a convert like this.

The reason Iīm asking is that I found an object with this kind of engine, and in the original shape it has carburators, so itīs pretty interesting to now if it can handle the CIS and the turbo with originally 2,4L pistons.

I recall a Bruce Anderson Technical article in Up-Fixin der Porsche in which he was replying to someone who had used 2.4T pistons to rebuild his 2.2 liter motor and ended up with compression readings of 75 to 80 lbs. The answer was that with the T Pistons the compression ratio had ended up being around 6.5:1. The actual ratio would be about 1:0 less than what the P/C would have given on a 2.4 so the S P/C with a ratio of 8.5:1 in a 2.4 would be 7.5:1 on a 2.0 crank. E with 8.0 would be 7.0:1 and T with 7.5:1 ends up at 6.5:1

I think 6.5:1 is what Porsche used in the first Turbos so maybe 2.4 P/C were used to get a similiar setup.
