I've seen some crazy numbers out of the old 4.0 v6, but I'm thinking more conservatively, maybe 80-100 hp/trq increase. As for economy, I haven't been able to stretch the car's legs yet, but highway is rated close to 40mph (imperial, not US). I'll be testing that soon.

not bad re mpg. I was at Metro Ford last night looking at a 12gt vert and the mpgs were 23/37. Not bad for a 5.0 I must say.

As a temporary solution to get better performance, you could upgrade exhaust, 93 oct tune, 3.73 gear + big sticky tires. Installing turbo kits are awesome but a lot of work. plus as a DD reliability may come into play.

As a DD, I was hoping not to do anything that would increase DD costs (one time costs, I seem to be OK with). CAI is on order, I was considering a tune, but that would be redundant if I bought a turbo or s/c. gears are out for this reason.

you seem informed so I do not see you wasting any dough

google education ftw.

Edit: Anyone have any experience with TMA turbos? I see they seem to be working on a 2012 v6.

I've been watching Jenna's project for a while. If the results with her 4.0 kit are any indicator, when she and Brian get this done, it will be a beast.

Jennifer Anne does have quite the build going on. Its a fun one to follow.

for some reason I think the 4.0 is a stronger base line motor to start with but I could be so very wrong
