Previa S/C injectors in 20v

[greenae102]

ran across this on another forum but it was just one person noting that the injectors are side feed like the 20v but flow more. The motor is a 2TZ-FZE. I found pics of the injectors and they are side feed like the 20v but i cant find anything on the flow rates let alone anybody even using them on a 20v. Def considering trying these out on my 7ag bc theres a s/c Previa at the you-pull-it up the road right now

4age 20v fows 295cc
4age gze flow 365cc

another replacement would be some sr20 nissan injectors. here is a link to all efi injectors and sizes. toyotas use nippon denso style injectors

425cc and yes they work i put that out in the last club4ag forum ....might be overkill on your engine...look for the 1jz 380cc unless u have an aftermarket ecu where u can control the injector flow

First you need a wideband. Big fuel mods without one is just a bad idea.
If you are running lean then you need to fix it, if you aren't then you are wasting time and money. Increasing the displacement of your motor 12% I would want a WB on it from the get go just for peace of mind. That said, if you are running a ST ECU the AFM will do a lot to compensate for the added airflow. If you are running a BT ECU then you will be running about 12% lean +- any variation in VE.
With a BT you would want to look for an injector about 12% larger. With a ST you may have a little more range. I don't have personal experience with the 20V ECUs but my GZE ECU can handle a 5% variation no problem. I am currently running the 1JZ 380s on it and with some small AFM tweaks it is great. When I was on the LP motor I tried 440s and it just would not handle them well. Given some time it will remap best it can and get better but it was still way too rich in closed loop.

Yeah my injectors are 440cc but my engine is heavily modified... I think u should use stock injectors see where ur at and then go to the 380s if u need more...when i originally posted about the previa injectors it was referring to good setup for turbo 20vs
