Welcome to the site!
I think 6 cylinder swaps provide the best "bang for your buck" when it comes to HP/TQ and the added weight would be comparable to a supercharged or turbocharged version of the M4X. The increased displacement will also provide a solid base for future modifications (in case you get bitten by the HP bug) and will also provide a more liner powerband and increased reliability. The swap is very straightforward and extensively documented in several threads on this website. I own two swapped 318ti(s) that my wife and I take to autocrosses and HPDEs. I daily drove her car for 4 years with a 700 miles weekly commute and the S52 returned an average of 26 mpg with a 2.90 lsd and 90/10 highway/city.
Where in Georgia are you located? I'd love to take you out for a test drive and discuss your options. |
