I realize Cincy's one ofthe experts on this subject..but what is the consensus ongoing to 2.0?Displacement is important, but what are the gains for a fairly heavily modded 225w/o a bigturbo...I figure witha good bit more airflow that stock, I could see 15-20 hpgain along with a little torque boring to 2.0.Does that soundreasonable?

 

yeah you'll see more power through the entire rpm spectrum, also faster spoolup. plus youll have forged internals which is the biggest thing to me. it kinda like...hey if im gonna build the bottom, why not go bigger displacement. honestly though alot of guys that have amu's, bea's, or aeb's dont do it cause you have to downgrade the pistons.

 

Since every 1.8t uses Mahle pistons, i dont know how ones better than the other. I would also have to claim that JE, Wiseco, and even aftermarket Mahle are just as good as stock. Plus you get the option of selecting the c/r.

Heavily modified and stock turbo should not be used in the same sentence. If you install things like cams, intake/exhaust manifold, and big port heads on a stock turbo, your basically tossing money away. you can only make so much power with a turbo that can only move so much air.

 

Volume=Power, heres a question but how big can we bore over? is 2.1 or even 2.2/sleeved even possible?

 

you can do 2.1 with a tdi block and crank and 2.2 with a tdi block and a eurospec crank.

 

but wouldnt a 2.2 cost a lot? like a lot a lot

 

2.2=5000 bucks

 

the block codes i mentioned are all factory forged pistons. ive seen 30+ psi on these pistons with just aftermarket rods. not sure exactly how much boost, the guage on the car im thinking about only went to 30.

 

All stock pistons are forged and can easily do 30+ psi and make 700+ bhp.

The cost of the 2.2 project isnt as bad if you source the stuff out yourself. I still wouldnt do it since you have to use eurospec stuff.
