larger injectors ETC on stock KA

Hey guys, I have a few parts and instead of having the sit around, I kinda wanna install them on my vert. These are the parts I have:

  • 500cc injectors
  • top feed fuel rail
  • walbro fuel pump
  • AEM adjustable FPR
  • SAFC 2

I was wondering if this stuff would make my stock KA run like ass? And would my fuel economy suffer or anything? I also have a JWT KA-T ECU. Would it be better to run this or the stock ECU?

I don’t wanna install the turbo or anything until I have enough money to redo the IC piping, recirc the BOV, install a working EGR and recirc my dump pipe back into my exhaust (I hate the noise the screemer pipe makes).

Is the car running fine at the moment? If so, I would wait to install all the parts, when you install the turbo. Then get it professionally tuned. This would save you the cost of tuning it twice. Your not going to gain much by just doing a re-tune and adding more fuel, unless your changing the intake plenum, header, cams, etc., I would just wait for the turbo.

The car is running fine. The thing is that all these parts are on my other Coupe, which I am planning on returning to stock. I just don’t have the stock parts for it so I wanted to get them from my vert.

I don’t really care about gaining power or anything like that. I was just wondering if the car would run properly with those parts.

holy crap we just did a thread like this one last month use the Firkin SEARCH function… !!!

just in case you can’t figure out the 'SEARCH ’ function Here’s a brief recap

  • you gain nothing by installing the parts if your not adding ANY form of forced induction Fuel + nothing = nothing.
  • car runs fine ( yes this other post WAS identical to your post ) so why wold even think of messing with it…

but hey whatever, you feel the need to install items that will do and gain you naught and cause you tuning problems… your call… good luck with that.

you can add tjhe 50lbs injector , JWT ecu , top feed rail , aem FPR , fuel pump , the car will run but will not be any faster then it is right now, it may actually be slower because the JWT ECU is a boosted ECU and the timing curve is lower that a N/A ECU.
I am speaking from experience because I ran my car like this in the past.

  • than again, I had a wideband to adjust my air fuel accordinally *
