Yum twins!
Hey Tony have you ever considered going with a 3MZ block to gain some displacement? Or that may be another surprise?

how cute.... twins :D :thumbup::thumbup::thumbup:

With that kind of power, I don't think Tony needs any more displacement. :lol:

Tony I think the entire TN family has been waiting for your update ever since your first talks of twin GT28R. Camry is looking great as ever, keep us updated and continue making history!

^ i think the goal is a torque-based goal .... roast tires from a 60-roll .... probably not gonna hit 800whp from twin GT28s unless theres a miracle though

More updates coming soon :) I am finishing off the wiring currently and pretty soon I will be completing all the pipework for those turbos... Hoping to finish everything by this weekend!

The manifolds are indeed a lot of work, but I managed to save quite a bit of time by modifying the OBX units. I purchased these a while ago and mainly sourced them for the head flange and bends. The front manifold was modified to become a sidewinder, but the primaries were kept intact. The rear header however, it was totally reconstructed. Both front and rear manifolds now has a true 3-in-1 merge collector as well. I will take pics of the manifold once they go through the finishing touches (coating them, etc..).

Each GT28R (GT2860R to be exact) is good for about 320-350 WHP, so both of these turbos are good for 700 WHP. It is actually about the same as the single GT40R that I had before, but this time, I want to feel the difference between a twin vs single setup with turbos that are similarly sized. To me, it's also a chance for me to experience the difference because I personally never went from a single to a twin turbo car with both setups being rated for identical HP levels. The engine is the same as before, just freshened up with new rings/bearings :)

The way I designed this setup also allows room for future upgrades... Depending on how I like the twin turbo setup, I can upgrade to twin GT2871R turbos if I decide to, and this would allow me to run up to 850 WHP or so. They will be a drop-in upgrade for more future growth. The way the manifolds are designed also allows me to rebuild a small extension section (manifolds will be V-banded) and convert my setup back to a full single setup as well. This will allow me to drop in my old Supra's T51R KAI turbo which is also good for 850 WHP or so. Lots of flexibility in this setup...hah
