1JZ going single is delayed...

Due to economic road block (the wife wants new kitchen appliances). I have to forego going single another year. So next best option is to get the most out of my stock 1jz. My plans are to install a Bigger Y downpipe either ebay or some other brand. 3" exhaust with free flow Cat into magnaflows. 550 injectors with upgraded pump. FMIC and NEO already installed. I considered cams but I engine is so smooth that I will seriously pissed with a change in idle (Lumpiness).

I am hoping for 325-350rhwp. Is there anything I am missing? Search yielded mostly upgrades to singled 1jz, not too many BPU 1jz. Any recommendations or am I missing anything? Thanks for input in advance.

Thanks man, just wanted I wanted to hear. I if come close to those numbers I will be happy and not worry about going single after all. Alas, I think I blew out my differential today. So it's at the shope now. But I am glad for you input. Just wanted I wanted and needed to hear.

i forgot to mention i also have a walbro 255LPH, with stock 1jz injectors, i think they are dutied at about 75% so you could hold off on the 550's if you wanted.

every car is different tho.
