I think all you'd have to do is get the turbo and the high boost software. You already have a built TSI!!!!

The kit without any previous mods will be my guess 10-12k

Ok so why not do the same for the FSI? Why stick with a tiny turbo and OEM style injectors for the FSI and give so much love to the TSI?

Sometimes I regret going BT on my FSI lol

Why?

 

[insideoutoreo699]

Why?

Because I feel like the TSI is a much better platform AND because I should have sold my GTI bought something else and then spent all my money on that haha

Yes. These are the injectors I mentioned working on back in late 2008, early 2009.

Tiny turbo on the FSI????

The FSI head does not flow as well as the TSI.
The FSI is more susceptible to knock than the TSI.
The FSI does not have as good of a fueling system as the TSI.
The FSI has more internal losses compared to the TSI.

The TSI is just better so it makes more power. We should expect that form a completely new engine from VW. That's how progress works. That's all.
