550cc injectors on KA24de!!!!!

Post by **WI_240sx** » Fri Jun 27, 2008 9:26 am

absolutely amazing!!!! thats the only word i can think for it...

putting the injectors in was easy.. taking the stock ones out... pain in the ***... i had to pry out the old ones with a screwdriver, but once the new ones were in, the car added about a third of the original hoarse power.. this very much so got rid of the "lag" that you feel in certain parts of the RPM range... it provides a very nice and smooth acceleration rate all the way to 7K.. instead of feeling that decrease in power you get at 5500rpm..

the brand i used was venom, but im sure any brand would be good...

my only advice is not to go above 550cc unless you have some form of forced induction, then upgrade to the 800cc...

are you serious?

This can't be for real.

550cc injectors on stock ecu and motor?Thats over twice the stock fuel!!

...370cc injectors are good for like 10lbs of boost on a ka.

you have to be running SUPER ****ing rich.

yeah, thats sounds right

i was just saying that 550 seems like a big injector for a naturally aspirated ka.

hate to jack your thread but

does anyone know if the 13b rotary motor (1988 rx7) injectors work on a KA without modding? there was a write up about it but i cant find it

Post by **WI_240sx** » Sat Jun 28, 2008 7:33 am

yeah.. its still NA KA24de, but considering that its always ran rich i didnt really care.. lol.. my cat is BRIGHT orange and slightly blue.. and its brand new... but i just got the new injectors on yesterday so obviously the previouse injectors did that... (needs O2 sensor)

injen cold air intake, 2.5 mandrel bend exhaust, magnaflow cat and muffler(south east wisconsin has emissions), short throw shifter, stage 4 clutch, 11lb flywheel, koyo radiator, welded differential, gutted rear, 4pt roll cage, racing harness, 300zx fuel filter, and i have a walbro fuel pump, its just not installed yet..

im debating if i wanna turbo it or not... its a oem ka24de out of a 95 240sx with 7K on the rebuild... i know its a high compression engine, but just about everyone ive talked to said that it can handle the extra pressure.. ive accually seen a KA run on 30 lbs of boost at a drift competition was i at..

Post by **WI_240sx** » Sat Jun 28, 2008 7:35 am

yup... thats my car

lol... guess you can just read whats there... bought of a buddy of mine with quite a bit of work already done to it... but im looking to finish what he started..

88 rx7 550cc's are top feed so you'll need a top feed fuel rail to make them fit. I got my top feed rail for my rx7 550ccs at projectnissan.com worked out great but you also need to get a nismo fuel pressure regulator since you can't run the stock one.

oh is this the thread you were looking for?? zerothread?id=109492

my car was already runnin rich when i bought it... had brand new ngk spark plugs in it and i took them out 5 days after and they had barely anything left... but im not going to do anything about it runnin rich untill i get the eletric fan to work... cuz as of right now the car has no fans, so i can use all the help i can get to cool down the engine.. but im puting a turbo on it.. already ordered it, so it should be here in like 3-8 business days.. and i need to replace the O2 sensor in it...

Post by **WI_240sx** » Sat Jun 28, 2008 1:01 pm

oh btw... if you could please take off that criags list post for personal issues.. its got the guys phone number and what not on it so it would be appreciated if you removed that... if you wanna know whats done to the car already just ask me..

This has to be the stupidest thing I have ever heard of; in my entire life.

The car is setup for 270cc injectors, not 550cc. Even with your bolt ons, which do very little, you are going to be running unbelievably rich...this is absolutely the stupidest thing ever.

And I'm going to throw up the bull**** flag on it running better and pulling harder.Do research before you do stupid **** like this. This has to be a joke.
