TRD n Blitz n Greddy offer complete kits for 2ZZ-GE, I believe there would definitely be one for 1ZZ too, wasay is right, you should go for a branded one for it comes with performance gaskets, manifolds, fuel-pumps, battery/bottles relocation fittings etc etc... n for sure, they add matchless compatibility! Don't ruin ur engine (and bay) with a desi-style jugarr!
