If you can weld then turbo is easy, if not supercharge. I'm running a GT3584 non RS wheel with a .82 hotside. GT3582 would work too. The problem with a smaller turbo is that you won't be running much boost for the volume. Look at a compressor map and you will see that 5-7 psi runs it off the map on most turbos that would other wise easily support 4-500 hp but at say 15 -20 psi.Thank you. Good comparison.
Can the stock MR2 turbo be added to the 2GR or do you have to upgrade to a more robust turbo? if so, what is the recommended turbo? In the alternative, is adding a Supercharger the better way to go? And again, if so, which Supercharger??
Also the torque will be quite lower with K24 vs 2GR so both being at 300whp I would say you would enjoy 2GR much more.You can actually make 300 whp through a K24 with nothing but off the shelf parts. That said, piston speeds are very aggressive, so it isn’t going to take abuse like a stock 2GR with bolt ons will.
