I mean no harm by asking this question. I only ask it because I am curious.
Why is everyone so obsessed with turbocharging the 2.4L I4 Camry? You would get monstrous performance if you instead looked into modding a 3.5L V6 Camry, no?
It is true that the few guys on TN with turbocharged I4 Camrys now develop more power than a standard 3.5L V6 Camry, but wouldn't all that effort and money have yielded even greater power if the project car was V6 based to begin with?
I definitely agree so much more with you. But there is a very large reason why the I4 Camrys are turbo-ed. If it was just as easy for the V6, then I'd be working on one now.
The thing about the 2AZ-FE engine is that it's the same engine as the Scion tC. Therefore, turbo manifolds are much more commonly available for the 2AZ-FE as compared to the 2GR-FE (V6). There are quite a few generic Ebay manifolds as well as branded ones. So with just the manifold available, the downpipe might be the same as well, not 100% sure on that, if not, it can be custom done by an exhaust shop. As long as you have the manifold, everything else comes standard, wastegate, bov, piggybacks/standalones (using the AEM FIC from the Scion tC works for the I4 Camrys as well, not confirmed for the 2GR-FE engine) Oil return and feed taps would be in the same spots as the Scion tC as well.
Heck, even a supercharger from the Scion tC may fit the I4s. You can even get BC cams for the 2AZ-FE...
If a company made the turbo manifold for the 2GR-FE to be more widely avaiable, there'd be a few more Gen6s with turbos. I've contacted a few companies on creating some, but it'd be very expensive due to the low interest. You can get a turbo manifold for the 2AZ-FE from anywhere ranging from $100-$300 on Ebay. Plus, you'd probably have to do a twin turbo due to the two manifolds for the V6. The only 2GR-FE that I know that has been turboed is the Camry from Cobb Tuning.
Last reason:
Only Gen6 I4s come in manual.
