Conrod lenght on 2,7 T4.

[T41303]

I think I will be using the 48 idf then, because this is not going to be a wild track-engine, but rather a reliable street-engine with a bit more focus on reability than wild rpm.
Another thing, do I have to take off some material innside the crank-case or cam for the 80mm stroke? What rod-lenght gives the least job?
Maybe I will go for the QSCUSA nickies and JE-pisons instead of the the Mahle, is there anyone that have any experience with the QSCUSA barrels and the JE-pistons?

I think the setup for the engine will be about like this :

80mm oettinger crank with 5,6 or 5,7 H-profile rods from CB, maybe there will be rods from Audi RS2, then the crank will be regrind to 48mm insted of 50mm.
JE 103mm pistons with 22mm wristpin and 103mm nickies from qscusa.
324 degree cam from german Schleicher with HD alu pushrods 1,7 std. rockers (8mm)and 911 swiwelfeet on Scat HD single springs.
Block machined for T1 lifters with Scat lube a lobe-lifters.
Heads will be CU -heads with 46 / 38 valves
The comp. I think I will have between 9,5 and 10.
Exhaust will be B.A.S complete system.
Carbs I think will be 48 IDF then.
And when it comes to the clutch I am a bit uncertain , will a 200mm cushlock with kennedy pressureplate be ok for this?

I am thinking that this setup should give a +/- reliable 200 hp street-power.

Would some of you have changed anything in this setup?
