LOL,
I traded my 07 Tiag 335 for an 08 135
I think you'll like the trade. And BTW, my 08 135 has had far fewer issues then my 07. Seems they got a lot of thing sorted out.
This is what I learned from my swap:
- LSD swap, auto to auto, internals can be swapped.
- All the suspension pieces can be swapped over. Swapped over my AST's (same springs) and m3 bits including front sway
- Except for the M3 strut bar. Need to get a modified version from HP for that
- Hold off on the rear sway, car does not need it as much as the 335 (but do the subframe bushings for sure)
- You do need a specific 135i oil cooler upgrade, not as much room
- AMS intercooler fits
- Intakes fit
- Wheels, yeah the ET's suck on the 135
- For track use (not autoX) may want to consider some brake upgrades (like new pistons / seals) Those 335 brakes were awesome.
Get the carbon blasted out and a used n54 will run like a champ. Honestly, I'm really happy with the swap. This car is more fun.
