has anybody converted their 3.2 TLs into a 3.5 TL? if so whcih engine did u you? RL or MDX? how much hp increase and how much will it cost for labor

 

do a search on the 3.5 litre upgrade. A dealer in Florida (I think it's Rick Case) is doing this. I believe it starts around $2500 and runs up to near $5k depending on which stages you choose. They pretty much use the Type-S engine, but do some work with the internals, and use MDX stuff. You can also do a search for it at acura-cl.com b/c they have dyno results etc....
