Top feed injectors , which ones?

[iaintslow]

I need high impedance top feed injectors. Can i use big injectors for NA? Or it has to be car specific for direct fit? Its a little hard to find high imp for 2jzgte here in US. Can i use any top feed injectors from any other high imp car?

I'm not sure what fuel rail the NA supra uses, but I know the standard fuel rail on the twin turbo uses a side feed rail, not sure if they are the same? Why do you need larger injectors? If you are using a custom top feed rail like an HKS twin feed or something similar, then I think it accepts most top feed injector. Have you tried speaking with Dusty at MVP as you are in the states, as I'm sure he would be able to offer you all the advice you would need, plus source any parts?

Yes i have hks top feed rail, wasnt sure if top feed injectors are all the same lenght etc... Im going single so i need some more fuel. NA supras use top feed high impenace injectors so i was woundering if i can just drop these in. I found 720cc for NA .
