do you think a 2.25" exhaust system will be big enough to run seriose power?


I seriously doubt it.


between 150 and 200 bhp  

2.25" i the biggest i can get past my rear axle.  2.5 touches the tank and axle.







i  had a mk1, and i made my own 3" exhuast....it didnt run on nothing....and we all know that mk2's, 3's, 4's, passat's....can fit 3" no problem.....

What are the key components to handling that much boost in regards to head gaskets and rings?
ARP or raceware studs?
What else?

Can you explain what you are doing with the pistons? The last one looks like an IDI piston. Is this an AAZ engine or a tdi you're making? Looks like a cool build!

How thin will the crowns be when you cut the notches for the valve clearance ?  From what I see, your compression ratio will be the same, same stroke, just smaller displacement.

Aki,

You are a madman. Kudos to you for your work. Looks good.  Do you foresee any issues with that welded turbo bracket cracking as the headers heat up and expand?  I'm sure that bar will heat up as well, but not as much as the headers.  If it holds, the triangulation will make one stout header setup.

Also, looks like you're teaching that young man RIGHT!  I wish I had your shop. Kudos again.
