Hi all,
I just wanted to start a build thread for a project car I am looking to start next year, currently in the researching phase to work out which parts I need and in which order. After looking around at many different engine options I found that the 2.0 TFSi engine would be the most cost effective to tune up for my goals. I did look at the 1.8t engine, however for big power its best to run a stroker meaning that the 2.0 TFSi would be a better option to start with, plus a newer design.
My plan is to build a car which has the same power to weight ratio as an Autounion type D (571 bhp per ton in 1939). This is due to my fascination with the early racing technology coupled with the fact that Audi kept the 4 rings of the Autounion brand. I have been looking at 2 different chassis to base this build on, the A3 8P or the A4 B7/8, the advantage to the A3 is that its lighter initially however the A4 has more engine bay space and will probably be a more stable platform (but heavier).
I think I am going to be going for the A4 option as I will be running a big turbo(s) plus other piping etc in the engine bay so the longitudinal design of the A4 would suit my needs better. The car will also be 4wd as its not an Audi unless its a Quattro.
Here are some initial rough specs I am looking at:
Requirements/goals
571 bhp per ton
Street legal
Looks almost stock from outside (sleeper look)

Here are some initial rough specs I am looking at:
- JE pistons
- IE rods (rifle drilled)
- Stock crankshaft (still need to check if this is ok)
- RS injectors
- Uprated HPFP
- Uprated low pressure fuel pump
- Larger intercooler
- Meth injection
- GT32 or larger (I have a GT35 and GT45 on the shelf)
- High flow cats
- Supporting intake and exhaust mods
- Will also look at camshaft options, however the stock cams are apparently quite good
