have a chance to purchase these injectors for cheap. if i want more fuel efficiency than power should i be gettting 50hp injectors? or am i better off with newer injectors no matter what compared to my originals with 170K ?
thanks

 

i wouldnt buy 370s unless i was desperate or i didnt care about crappy performance and a ton of heat.. ur better off spending more money buying a proper injector that will have the right spray pattern like ones from New era, DDP or Industrial injection b/c more then likely ull be going to them any way but b4 u start moding the truck get gauges

 

Adding to 97 D-Tec
They are cheap and reliable horsepower. Nowhere does "fuel efficiency" come into the description.

Down side is they do not work well with a stock 94 pump. Your stock delivery valves (DVs) will usually cause a problem. In fact, most larger injectors will be a problem with your stock pump.

Cheap & efficient power? Find a used set of injectors from a 96-98 manual transmission or commonly called 215 injectors. A little jump in power and very clean injectors. Usually no problem with your stock DVs.

 

Watch what you say about DDPs and II injectors being the correct spray pattern.
If you search hard enough you will find the answer.

 

care to point in the right direction?

 

Not sure about II but DDP 12v injectors do not have a 145* spray.

 

I know coaltrain offers a 370 type injector with the correct spray pattern

 

different injectors for 5spds?? interested in feedback from those who have or have had the 215's. cant get more than 18mpg highway no matter what i do. 2 more mpg would make me very happy.

 

DDP starts out with a marine 370 and EDMs them and the extrude hones them and raises the pop pressure to around 300bar IIRC.
Thats why they dont want you to run anymore than 20-22* of timing with them.

PM Don Wagner about some NICE 145* 265bar injectors. He sells them and they are night and day difference than my DDPs.
