DSM 550cc injectors on a ka24et

[ArcadeMod]

Ive got a sohc block with forged internals coupled with a fully titanium rebuilt head. Walbro fuel pump hooked up to my stock fuel rail. my friend eric says he has 550 injectors from his stock 2g eclipse. Can I just pop these into my 240 manifold? Will I need resistors? If not then does anyone have suggestions as to what injectors to buy? This is my first motor build ever so I kind of have been struggling.

is he sure it is 550's & not 450's? It seems like it will fit since dsm 450 works.

Typical Injectors Used on SOHC

DSM (Eclipse/Talon/Laser) 450cc Injectors *Low Impedence*RX-7 T2 550cc Injectors *High Impedence* Denso 195500-2020RX7 FC NA Top feed 460cc Low *86-87*RX7 FC NA Top feed 460cc High *88*RX7 FC NA Top feed 460cc High *89-91*RX7 FC turbo Top feed 550cc Low *86-87*RX7 FC turbo Top feed 550cc High *88*RX7 FC turbo Top feed 550cc High *89-91*RX7 FC NA Top feed 680cc Low *84-85*CA18DET 370cc Injectors *Low Impedence*

And DSM's use low impedance, so you need resistors - either getto rigged, jgstools.com custom resistors, ebay, or dsm/honda resistor box wired in line. There is a DIY on this forum by fiznat - think it may be an article or sticky lying around somewhere.

I have a set of rx-7 550cc injector that are high impedence and have already been cleaned, flow tested, and balaced for sale. 200.00 +shipping. they are used but only about 1200 miles. let me know if you wan't them.
