I chose to keep the factory pump in tank as nothing beats Toyota reliability. It's the same pump that the MKIV Supra's have from the factory. It alone would be able to support my lofty HP goal on race gas, but I want to step it up a notch and run E85. E85 is amazing in every right but mainly because it's $2.15 a gallon and 110 octane!
So with E85 in mind and knowing you need 50% more delivery then standard fuel. I opted to purchase a surge tank that houses dual fuel pumps within. Two Walbro pumps were installed as they are cheap and VERY reliable. The surge tank came from a seller on ebay, I think it's a very quality part. The only down side is it's lack of mounting brackets witch I'll have to tig on to it.
My buddy Justin was always worried that when running two pumps and one dies the car will still run but lean enough to detonate. To combat this I wired both up in parallel using one 30AMP fuse. This should pop the fuse and kill both pumps if one pump fails, killing the fuel supply instead of letting her run lean.
An HKS style fuel rail and Injector Dynamics ID1000 injectors were installed. If you ever want to be around me when I'm ready to kill some one, a fuel rail install on a 1JZ with the engine in the car would be the time to see it! I can't say enough good things about the ID injectors. They work better then any large injector I've ever ran. The car starts easy, idles smooth, lag times are minimal and they will flow over 1300cc! The E85 also dropped my EGT's down 1000 degree's and my A/C blows unbearably cold! Anyone who's ever had an E85 tuned car can tell you how hard they can be to start, but not with these bad ass injectors. www.injectordynamics.com
