XSI Twin Turbo

[PUGNUT_XS]

be limit is not 220 bhp, its torque limited, I know quite a few running significantly more than 220 bhp without any gearbox problems other than the few animal drivers, but they tend to break shafts.

I think there's another reason to stick to a good single turbo, which is the head, these engines just don't rev or flow as well as a 16v, so you may well not be able to make use of a twin charged setup anyway, just isnt the air flow to make it work.

Agreed, you would need to do some work on the head to make it flow better, cat cams do a fast road cam for it too.  This engine is designed for low down grunt, which it does well, with the BE3, i was advised not to go over 220 BHP in stock trim.

I dont know how much fact there is in this but aparently the GTI-6 RS head will fit the J2TE block and run using the stock internals.  I can say that the head does fit as when i was building mine i tried it.  The RS block and the TE block are the same, just the TE has the turbo fittings on it, i compared them when i was building my car.
