Q45 injectors
 

Does anybody know if the Q45 370cc injectors are the same injectors as the stock SR injectors? Im looking into buying a set for my KA-T project and need to know if theyre the same before I buy them.

why dont you just buy aftermarket injectors probably easier to find and cheaper to

forums are over flowing with stock sr injectors. average price 120 bucks..

Side Feed
Engine Style Size Impedance* Years / Models
Nissan KA24DE Side feed 270cc High S13/S14
Nissan SR20DET Side feed 370cc High S13/S14
Nissan SR20DET Side feed 480cc High S15
Nissan RB25DET Side feed 370cc High R33/R34
Nissan VG30DETT Side feed 370cc High Z32

Infiniti VH45DE Side feed 370cc High All Years

NOTE: 90 - 94 Z32 uses a style of injector that is non-compatable with KA fuel rails (still sidefeed), while 95 - 96 uses the same injector as the RB25DET and SR20DET, etc.

note in order to run low impedance injectors. you must install one of the following resistor boxes

obd0-1 preludes, obd0 civics, crxs, and integras, as well as g1 and g2 eclipses and talons

So if I understand correctly from this Q45 injectors are plug-and-play for the KA motor, correct?

go for it. The S15 injectors sound sexy Ry

yea i sold my sr injectors for 100 bucks a while ago..not hard to find

As sexy as the s15 injectors would be, they'd be overkill for a t25 (which is what im planning on running)

Dude T25? Project: Good Lordy 240! should run nothing less than a T28BB (S15 to match the sex injectors). Keep it real homie

im picking up STi injectors next week.

whats the flow rate on those biggame?

------------------

The following chart displays the maximum obtainable CRANKSHAFT horsepower vs. injector flow rate at 100% duty cycle, assuming a BSFC of .55 lbs./hp/hr. For Wankel and 2 stroke engines, multiply max hp in table by 0.9 to compensate for the higher BSFC of these engines. Injectors should be sized for 75-85% maximum duty cycle on engines used in constant high power applications such as race cars, aircraft and boats.
