cylinder head porting
So I was looking at porting my head for my audi tt225 and I came across Port Tuning. They do the whole job for about $1100 which isnt bad I guess. They say i would gain anywhere from 25 to 30 hp. Would it be worth it? I have to do the T-belt and waterpump soon and they said they can do the whole job for about $1700. Just for the t-belt and water pump where I live cost $1300. So I figured for the extra money why not get a little bit more hp. Has anyone done this to there car?

i have a big port head sitting for my car i havent installed yet, it has been extrude honed and all intake valves were bored one over. head work is always a great mod, and the more other stuff you do the more it makes. i would go through with it personally.

stock big port > ported small port. There is a section that you cant really port out on a small port to equal the big port.
The only problem with swapping heads is you have to take account for things like water pump (external vs interanal) and vvt. So there is a little extra cost involved also.
Im sure the ecu will adapt to the new airflow but like ray said, it wont be optimized unless tuned for it. Kinda like adding cams.

i dont remeber all the details. there is a thread or two about it.savwko i think started the big one, also you can find the thread where 02vw(somthing) cut the small port head up for comparisson. Think both are in the 1.8t faq
