I was talking to a buddy of mine from the east coast where i am from and he got a VW GTI. he said it was a 1.8T with a VR6 upgrade. I asked him if he bought a VR6 or a 1.8T then he said the same thing so i said that they were two different engines "a 4 cylinder and a 6 cylinder" i dont think he knows much about car mods though. So then, he assured me it was a 1.8T because of the emblem on the back and he said it had a VR6 chip. I dont know much about VW parts so i just went along with it confusingly. I asked him what mods he has done to it and he said that he had headers, intake and exhaust......i am pretty sure something is wrong here as you can have an intake with headers on a turbo motor, atleast on a nissan...is he an idiot or is he right? i think something is wrong here, so i wanna set things straight tomarrow when i talk to him

He's an idiot.
A 1.8T is an inline 4 cylinder. A VR6 is a V-6 with such a narrow angle that it uses a single cylinder head. It's either one or the other. I'm sure they make chips for VR6's... but even if they're compatible with a 1.8T, it's not going to turn it into a VR6 at all.
A turbo car can have an intake and exhaust. But not a header. A header is strictly a naturally aspirated mod.
lol...i love the first remark to the response...made me laugh...but i said the same thing to him i said you either have to have a 4 cylinder car or a 6 cylinder....ill get this straightened out tomarrow.
yeh i dont think he does, he is new to car tuning so i guess they are common newbie mistakes....hey i see your from maryland..thats where i am from and he is to

I suppose a supercharger could, since it's driven by a belt (usually). Think about how a header works, and how a turbocharger works. The header's job is to get the exhaust out of the cylinders and into the exhaust pipe as efficiently as possible. A turbo, though, is bolted to the turbo manifold- which goes in the place of a header. A turbo's job is to use the airflow of the exhaust gases to spin a turbine, which pumps pressurized air into the intake.
A header and a turbo manifold are two different things. If you have a header, you can't mount a turbo. If you have a turbo, then getting the exhaust gas out of the car isn't going to help you- the goal is to get it into the turbo.
So... if he upgraded the piece that goes from the exhaust ports to the exhaust pipe, on a 1.8T, it would be the turbo manifold. And there's no point in upgrading the manifold without upgrading the turbo itself, and using lots of engine management.
And, no, you're not the idiot- because you actually asked. There's nothing wrong with asking... the people I laugh at are the ones who have no idea what they're talking about, and talk about things like having parts that don't exist for their car. I'm not saying my explanation is totally right... and I encourage any other opinions... but at least I'm not going around saying I just got a triple core radiator for my '75 Beetle or some other stupid thing like that.

There are chips for both engines but they are NOT interchangable. Send your friend here: www.vwvortex.com They know their shit.
