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.

Thanks to IWannaS15 for sending me the original list!!!

If you have additional info, please feel free to post it, I'll then add it to the database and delete your post. This is to be kept clean at all times, anything other then injector info will be deleted post haste...Thanks

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.



Just HP vs flow. From http://www.sdsefi.com

I believe :Toyota Celica GT (5sfe engine) has similar 315cc high impedance injectors as the Toyota 3s-ge - might be easier to find :P

I second that one!

SR20VE / SR16VE - 333cc Grey Top Injectors

Pretty sure the Toyota MR2 3sgte uses top feeds.

Great reference guys - Good work!

And welcome to our visitors from elsewhere - this page has been pretty popular!

2 best lookin mods on nico....what did ya expext...lol.

According to that chart a set of 615cc should max at ~ 429 crank hp...??? Then that would mean ~ 356 whp...

Why does that not sound right..??

A general rule I use, take the number of cc's subtract 100 and thats the WHP you'll net.

so 615cc - 100 = 515 whp..??

Still sounds off to me. All other calculations state ~400-425 whp. Im not doubting u in any way but 515 sounds a bit high but would be SWEET if that was the case..

well doesn't it also depend on the num ber of cylynders my friend with his turbo mustnag only uses 24lb injectors which are smaller than stock ka injectors how ever he has twice as many of them so they therefore provide enough fuel.

Here is a topfeed chart

http://hybridka.com/misc/TopFeedInjectors.pdf

Someone on ka-t.org posted a link to a OEM injector reference guide. They are listed by part numbers and has a picture of each, plus flow rate and impedence.

no, side feed

do the vh45 injectors drop right in the ka24de fuel rail?

Yes

do mazda FD sidefeeds fit the stock fuel rail? do the electic plugs fit also?

are 550s from the twin turbo?

Mazda FD Side feed 550cc High 93-98 are the injectors you'll want. Yes they drop into the rail but I don't think the clips match up. I haven't used any so I can't say for certain, I switched to top feed right off.

Ok, here's one for ya. How much work would be involved in making standard ford/gm style delphi injectors fit a KADE intake manifold?

Are the injectors in that list ones that fit the KA engines?

No, theyre injectors that MIGHT fit based on top/side feed or hi/lo impedence. Some of them drop in, some need clips or O rings...

To make ANY of the top mount injectors fit a KA24DE you'll need a new top mount fuel rail. Project Silvia sells them for like $30. http://www.projectnissan.com/s...=3701

nice.... tha

nice that way i can switch to dsm 1g injectors my friend has laying around... all i need to do is wire in resistors.....

hey so will the j30 injectors work for the kade rail...is it a plug and play job???

I think they are drop in replacements, but there may be a year or two that doesn't match. I just can't remember...

are these 370cc also???

Yes

here is my problem i got the injectors but they are still in the rails and i cant seem to get them out of the rail...what is the easiest way of getting them out without damages them???i damaged one already and i dont want to risk the rest...i got 5 left to try to get out without damaging them...thanks for all the help...
