1G DSM 450cc Turbo injector's

[T61 260Z]

I would like to know if I can use some injectors from a 1g DSM?

also I would like to know what the proper upgrade injector's

are for a L28ET.

 

Thanks,

Armando

they are low impedence injectors, i dont know if the l28et injectors are low but if they are i dont see why it cant be done:D

I found out in the seach it can be done either with 390cc's or 450cc's.

I think the size of the injector depends on HP level, You don't want to put in too large an injector otherwise your idle and low speed will may suffer depending on how your firing the injectors, sequence or batch. Somebody correct me if I'm wrong.

Thanks,

 

 

I'm also putting in a S-AFCII and AFPR.

You can put any injector in there that will mechanically fit properly to the intake manifold. And depending on what fuel rail you use, it needs to seal properly to it. Any Bosch style injector will fit.

 

Now when it comes to flow rate, if you retain the stock engine management, you are pretty much stuck with the stock 280cc/min injectors. If you put anything larger in there, it will run rich over all operating conditions.

 

You have a couple of options as far as adding more fuel for increased boost levels. You can use an adjustable rising rate FPR to tune for max boost and power, keeping the stock injectors. This will get you the proper tune for max power (within the limit of the stock injector flow rate), but you may have some rich or lean conditions during idle, or part throttle condiitions. You can also add an aditional injector controller. SDS makes one that looks pretty nice. You will need to add a couple extra injectors to the intake plumbing before the throttle body. The controller will only activate the addiitonal injectors at a boost level you program. So you can keep you idle, and cruise mixtures stock, and then tune for max boost and power. This is the best approach IMO if you want to keep the stock ECU.

 

Many people have modified the stock ECU by using Z31 components. This is an option if you are real good at this kind of stuff. For me, the sooner I can get that 20+ year old electronics out of there, the better.

 

Lastly, if you go with an aftermarket engine management system that allows complete tunability, you can use any flow rate injector you want. I would stay less than 450cc/min so that you can still get a smooth idle.

I run the blue top 450cc DSM injectors. I'm running them on an O-ring rail with my SDS. I like them alot so far.

Thanks for the information,

I'll try the 450cc's frist and then if they work

I'll keep them in.

What are you using for an ECU?

[T61 260Z]

Stock 75 N/A ECU.

I will barely run, if at all. The stock NA injectors are 180cc/min. You will be dumping more than 2x the fuel in there. If you switch to Megasquirt, you can retune for the new injectors.

These are 430cc and have the same hose barb mounting that the stock injectors have so they work with the stock fuel rail. You won't make 500hp on that rail but it will get you above the 280-300 that the stock turbo injectors run out of flow at. I also highly recommend Megasquirt. I am running it and it works great. Oh, I am super low budget, the above injectors I got from Rockauto.com for $45 each. Not the way to do things proper but effective for the money.

it runs good on the N/A ECU. SO I will try it for awhile. Also I have stock

81 280ZXT 260cc's injector's @10psi and run's great.
