Well I have put 5k miles on my build so far and have no cooling issues at all.
So idk if I would want to trust such a small radiator. But with the expansion tank I wouldn't say it wouldn't work.

Trigger wheel is the hinson wheel. Its a machined pulley. You can look at there website for more details.
Oem radiator is efficient enough. We have nothing in fron bumper anymore so airflo goes straight to the radoator. I have the gm coolant temp sensor in the front driverside of the head and the oem sensor for the gaige in the back passanger side if the head. Both sensors never read over 190 and in traffic will on a hot texas summer it never goes over 220. One constant running fan and we have another fan that is switched on by the computer at 220. All chevy lsx blocks from the factory have normal operating temps of 220. Overheating on a chevy is 260.

I apologize for not posting them yet as I am building a rx8/t56 for someone and wanting to make sure this goes smooth and while building it I will have every detail about the swapping procedure to make it very simple for others should be done by the end of next month. It will have my bump steer kit and trigger wheel heating and ac

Hey man, I just wanted to say I think it's really cool you actually did this. I have been watching this thread for a while now, and it's just really cool to see that you didn't get discouraged by the negativity you received. Way to go.

This is true!! I unfortunately cannot start threads yet, however I am working on a 2005 RX8 with Forged 347" LS1, T56, Turbonetics TC78. It will be operating on a 2013 Corvette ZR1 Electronic system for maximum boost control and will also have partial OEM RX8 harness for certain onboard function like trac control and ABS. I come from a family of software developers & computer scientists, so we have almost finish a electronic gateway & infotainment system that would unite the mazda and GM systems.

im planning to do an ls2 swap i already got the engine but everyone is telling me to do a 2jz swap instead..much easier..handles more power and no need to rebuild the whole engine just the block..the ls2 comes with 400hp stock..does it really need to be rebuilt to handle more power? for the 2jz u only need to weld 2 rackets that holds the tranny and the motor..could anyone tell me if the 2jz is a better choice? doesnt the 2jz give better mileage? the ls2 is too strong for the rx8 and the handling would suck or so i heard

That being said, the LS2 is safe to about 650whp on stock short block with boost and very good tuning, maybe 500-550whp N/A. I am doing a LS1 (5.7L vs 6.0L) with forged pistons & rods, but stock crank as that is generally safe to approx 700whp, again it all depends on a solid tune.
Im not sure how the 2JZ swaps go, but from what i see in the LS swaps, the electronics are the primary hold up on making everything function properly.
