I have the one on the bottom(smaller one). It works great. Its been 2 years since I installed it and I havent had any problems. I was told by an old alltrac owner who had a brother with a supra that said the larger one pushes a higher fuel pressure ratio per psi of boost. The one I have is 1 to 1. Psi of boost to fuel. I think the larger one was like 2 psi of fuel for every psi of boost or somthing like that. If you're going to install a fpr I recommend you bore out the fuel rail and make it dual feed while you're at it. Mine is a dual feed now, but didnt bore out the rail. I regret not doing it while it was out. I hope this helps.
