Lets start with I've replaced the transmission, transfer case, and rear end (Explorer swap). Now they all have pretty much 60,000 on them and I didn't rebuild them just opened them up and check it out. Now the engine has 155,000 on it right now. I want to replace it with a rebuilt motor (as I can't have the truck out for to long) but I was thinking that I'd like to in the future run a rear mounted turbo. I've been checking out STS turbos on the Toyotas and I don't think its to crazy to think of doing, I plan on running around 8 PSI. I'm not going to fully build the engine with forged everything but what are some things (cheaper) that would just make sure that its going to survive. So what should I do, its a future plan but sooner than later. I'd like to throw a composite upper intake manifold, roller rockers, and a set of pulleys. Then probably just gasket match everything to improve flow a bit. SO lets see what I can come up with.
