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.

 

Check supramania.com

They have a lot of 1jz stock twin upgrade posts.

 

nope your right on the money.

I have FMIC, Stock downpipe, 4 inch mid to 3in duals, Greddy Profec B spec II,15 psi , AEM EMS and last time i was on the dyno i did almost 377 hp and compairable TQ

 

Sent you a pm

 

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.

 

I'll wait for you Nate, I'm not doing nothing crazy wise for power til maybe next winter lol.

 

Don't worry bout the single man, it'll come.

You can make those numbers well enough; I make 340 with busted coil packs and 13lbs.
