Sounds like there is no chance without lots of money being thrown into my gti
When in doubt... Drop a LS in it.
Is that plug-and-play direct swap ?
Well.... you could go K04 with all the supporting upgrades (suspension, drivetrain mounts, limited slip differential) along with some Hoosiers and maybe have a shot of challenging him at the drag strip. High 11's is doable and could be enough to give him a bad night if he doesn't prepare or know how to drive.
You're probably going to be in for somewhere around $10k to even think about getting close though.
They're running mid to low 10s out of the box with tires..... No chance, only way to beat that is a bad driver in the stang and a good driver in the GTI
Depends on what you mean by plug and play ;] lol
