well i dont know what you mean by "more efficent" but by any definition i can think of, a front mount set up is more efficent. the exhaust is hotter when it gets to the trubo the turbo spools faster. ect.

i got my 2114 used,but they can be had new and very nice setups from race proven motors (www.raceprovenmotors.com) then click syty. i got a lot of stuff from them including the turbo and fuel rails.

good group of guys and they know what they are talking about.

 

i got it updated over here

some ... interesting things have happend.

 

ooh ok. thanks.

i mean more efficient as in cooler air reaching the intake tho. the colder ur air charge is the more power u'll make

 

thats what intercoolers are for. you can usualy get away with not using one on a remote mount because the piping acts as one, some what. but you will get cooler air with a front mount and an intercooler than a rear mount and no intercooler. and you get all of the other advantages with the front mount.

both work good and can make good power, i just prefer the front.
