This is an older thread but I will add something very relevant.
1) You can *NOT* for a 4.2 V8 into the MK1 TT (8N) or any other Audi TT for that matter ... not unless you re-weld the frame and basically change the car and it's wheel-base.
2) You can *NOT* fit a 5.7 V8 or "LS swap" your TT. It won't fit. Not without Frankstein-welding things.
Should you want to go bananas and do it anyway, you need to bear in mind the Audi TT is built for a transverse engine, so you put an Audi V8 or LS swap it, all your mounts are in the wrong place. And then to put them in the right place, your drive shafts are in the wrong place to reach your wheels, and so on and so forth. Or you mount the engine up high, giving you a center of gravity you really don't want to have when you take any corners.
What *DOES* work is to put the Yamaha-derived 4.4 V8 into the Audi TT. This engine is found in the 2000s Volvo V8s and also a massively tuned and turbocharged version is in the Noble supercar. This 4.4 V8 weighs only 190kg (the 1.8T with all the turbo pipes weighs 178kg) and all the Volvos also have this engine transversely mounted so you can adapt the engine bay to fit this engine. However typically it less less effort to tune the 1.8t to get the same ~350hp the V8 will give you so people do that.
You can't fit this V8 with a turbo in the TT though... the space just doesn't quite cut it...you can get the turbos in, but no room for the ICs. Maybe you can position ICs somewhere else, IDK. Engineering without budget constraints can solve many problems.
To make it work you need to move the battery to the back
relocate some of the wiring and fuses on the right side of the engine (right side as you stand in front of the car).
You need to move the radiator forward a couple of inches (which you can do as you lose the turbo, SMICs and intake pipes related to the turbo), measure up the mounts for the engine so you can make it to the gearbox.
It is recommended to change the 1.8T gearbox to the 02M gearbox if your TT doesn't have that version of it.
you need to use an after-market ECU which can talk to the Audi instrument cluster ( I guess most new ones will be able to)
you will need wiring work to connect up the coilspacks etc - same for vac lines etc etc
If you leave the engine naturally aspirated the OEM gearbox, haldex and drive shafts can handle the torque. If you boost it, they wont.
