NA/Turbo Injectors?

[Clip]

Would I be able to swap injectors from a turbo into my NA. I think it'd be going from 330cc to 440cc. Would there be any noticeable power gains? Should I get a Lex AFM and an SAFC or something like an aftermarket fuel controller?

One other thing - what Lexus model AFM is swappable to the Supra?

why not some 550's even....i mean you can leave a nice coat of black on the moron tailgating you, that in itself makes it worth it.

First off, the turbo injectors will not plug in, and the lex AFM will not work (different design and function). Second, there is no need for bigger then stock which BTW are 315cc for the later and IIRC 295cc for the earlier.

The 295cc units are good for between 250 and 260 hp.
The 315cc units are good for between 270 and 280 hp.

So unless you are up to or beyond those number, going bigger will do nothing for you and actually cause you to loose power if you dont do something to compensate and cut fuel back cause putting bigger injectors is only going to cause you to run richer and the cars are already slightly on the rich side to begin with. To rich causes a lose of power....

Adding a fuel controller and a decent tune you would probably see some improvement (only because our cars run so damn rich), but it's most likely not worth it unless you plan on going turbo later and will still have a use for the controller. If you want to dump the "flapper" AFM you'll need to use a MAFT Pro or similar.

thanks for the help guys, cj, i thought i had seen somewhere that the stock injectors were 330cc, thanks for the clarification.

I accidently stuck 89+ injectors from an NA into my 86.5, car struggled to stay on. I dont know if it was tuning or the low/high impedence issue, but my guess is sticking turbo injectors in there is a bad idea.

with all the work why not buy a 7M-GTE? I just don't get it I guess.......... or maybe I'm Insane............or maybe your insane.

were all insane, were in love with a car that could run great and then suddenly bust wide open any second... we fix it and do it again, we never stop.
