Well I see that audi puts turbo on 1.8L and recently I saw turbo on new A4 2.0L. So question is when Audi will put 2.2 or 2.3 5 cyl with Turbo 25V.
the 5 cyl with 20V gives off ~175HP with 25V it should be 185-195HP then turbo gives to 250HP and as regular 280-315HP.
well for 4 cyl it was 90HP for 8V then 115HP for 16V and 125HP with 20V. Then 150HP stage 1, 175HP stage2, 225HP stage 3. the 1.8L engine got 100HP. The 5 cyl on stage 3 should push up to 300HP + mods pushies to up like 350HP or even more.

 

ehh they already played around with 5 cylinders.. no point in going back to them if you got something that is working just fine

 

didn't the older audi 5cyls have turbos.. like the audi 5000,4000 or what not or were those 4 cyl turbos

 

the 5000 came with a 2.3T it was 5 cylinders.. but 20v not a 25 valve
