Re: Thinking of doing remote mount turbo for 2rz truck
If you have a 2rz then go with a normal top mount turbo or nothing. The kits are cheap and easy to find and the performance will be much better. Bet it costs about the same as well.
On a 5vz where there are not turbo kits made for it, then a remote mount makes more sense.
Far as the turbo goes, skip the stock turbo idea, you can get brand new turbos now days for the same price as any used turbo worth using. Except for maybe the HX35 but that is pretty big for you it sounds like.
Do some reading on here, you will see that top mount turbos are common. They are also more or less plug and play.
