Check out my sig. There are links to my mods and videos. I have a LS3 427 and couldn't be happier. I had actually bought a 122 Magnacharger at first and then decided to just go N/A. The way I see it, it actually worked out cheaper to go N/A than FI. You end up making money back from your original motor and any other motor parts you get rid of. I bought a short block and heads and did all the labor myself. I think I came out right around $7k when all was said and done. That includes headers, exhaust, tune, etc....
Plus I have an A4 and made 502rwhp unlocked and 536rwhp locked. You would see more than that with an M6 for sure. Plus You'll have a 10 second car easily.
It's hard to make that power on FI without having other mods and the risk of damage on the motor eventually. Not to say it can't be done, but from my experiences, and seeing people try to make big power on FI, it usually take more money. |
