OK, i have a set of DSM 450cc injectors for stealth/3000GT. i have no idea if they will work on a datsun (im sure someone here does). but yeah...

ULTRASONIC FLOW CLEANED
INSPECTED
TESTED
NEW PINTLE CAPS
FLOW GREAT
# B450L INP 009

 

DSM injectors look the same, but are physically smaller than the 280zx / Z31 injectors. And they must be LOW IMPEDENCE injectors to work w/ the Datsun ECU. By the way... For Sales go in the MARKETPLACE: https://www.zdriver.com/forums/forumdisplay.php?f=68

 

my bad, and FTR they can be made to work with low impedence ECM by simply adding some 10ohm resistors...

 

Dimensionally, whats the difference between these and the L28 injectors? And how much are you asking?

 

i have no idea what the differences are, but im askin $150 obo

 

J... Here's a pic for all to see the diff in injectors:

 

Well diameter appears to be the same and that would've been my concern. Now if I can just figure out where to get those resistors for the AFM I'd be all over a set of bigger injectors.

 

the ford svo and the rx7 fuel injectors look perfect.. the RX7 looks like the ones i would like to have to mod.. hey nismopick whats the cc rate on thouse rx7 fuel injectors and what tear rx7 do i need to find thouse on ?

 

87 - 89 Non Turbo RX7 injectors are the ones for the swap. They are low impedence & 450cc flow. I have a set of 8 of the RX7's & SVO's... but I think I'll start w/ the SVO's.

J... if those DSM injectors are used, the tips would sit quite a bit up higher in the injector ports... do you think that would cause any probs?

 

I dont see it causing a problem. It doesn't look like it would be enough to effect the spray pattern. I cant be sure though. I see alot of those DSM style injectors on ebay all the time. They usually go for pretty cheap too. Only problem is you have to get em in sets of four that way

I wanna rework the resistor board in the AFM so that these higher output injectors can be used with no ill side effects. I'm thinking maybe splicing a pot in place of each resistor so that the fuel trim can be adjusted based on the position of the AFM door. That would enable the vehicle to run properly at idle and part throttle and then be able to let loose at higher RPMs. I could just go solid resistor but thats a lot of trial and error to find the right resistor for each position. Plus with pots it can always be adjusted.

 

well, if ne one is actually interested in purchasing...

$100

 

I bought all 8 of my 450cc RX7 injectors for a total of $75... they drop right in

 

Hey what is the stock cc's on the factory non turbo injector for a 280zx '82ish? Just curious.

 

185cc's on the non turbo. 265cc's on the turbo.
