what are the color=size for kade24s? i have a bad injector i need to replace. i will take a picture as soon as i get back to the car.

 

SEARCH!!!!!!!!!!!!!!

Dual cams have side feed 270cc injectors they have red tops.

Dont you have a single cam? If so they are different.

I have spare stock injectors.... for a dual cam.

 

tis true on the search. johnny's is single mine is dual. i have 370 sr/z32's.
at 9lbs with the t3/t4,should i bump up to 550s, lessen the duty cycle? i dont plan on upping boost anytime soon, at least not till i beef up the top end

 

370's at 9 lbs on a t3/t4 should be fine... 550's on more boost would be fine also seeing as you wont make over 350hp which is the weak point in KA's.


It is not the top end that is prone to problems on dual cams its the piston ringlands at around 350hp-400hp. Rods start to snap 400+.

Every motor is different some will break at 250 some at 350 some at 450. People have made 400+ stock motor 20 plus psi (on 200k mileage motors). Some have even hit 500 with aftermarket cams stock bottom end and ran like that for awhile. I think the highest was cory on ka-t he made 532.


Its honestly all in the tune. Good tunes will make your motor last longer. Am I saying 400+ hp is a good idea on a ka, NO. It is possible yes, although it will not last forever it will last awhile with a good tune.

If your like me, I have spare motors so I could careless. Not to mention buying another KA is dirt cheap. Its not like your buying another ls1 or something.


If you want KA-T info go over to KA-T.org. You can look at other people setups and gain alot of knowledge about the KA motor and what setups are capable of what etc etc.


BTW if you search on KA-t you can find the stock injector mod. It makes them flow 584cc. The spray pattern is changed a bit and is deff a budget setup type deal. But people have sent them out to injector places to have them flow tested etc etc.

The spray pattern came out as good and they all flowed the same (584cc). If it were me and I would just buy legit 550's but if its a budget setup and you dont care try it out for shit and giggles.

 

yea shes my daily, maybe ill try them on the 3 that will be usless if i buy all 4. i need one 370 with good o rings.
if im stuck buying new ones i were going to get 550s, seeing that im at 323hp. was just thinking im pushing their duty cycles around 60-80%. i didnt do the build, but supposly the bottom end has been beefed up. im waiting on a exact parts list from the kid/ reciepts.

i never had a problem till the 1st turbo blew. the one i got off you,"my bad for coming at u wrong" does have a bad seal, no biggie. now waiting on injector and a new mani. o atleast get her drivable again. still looking for a new t3/t4. just funds are seriously tight right now. even harder to make money with no car:/

thanks for the help.

 

370cc injectors past 300hp is way more than 100% duty cycle. 320+ on 550cc injectors is around 80-90%. Depends on fuel pressure.

But I don't see how your making 323hp on 9 pounds on a small t3/t4 with 370cc injectors that impossible really. Might want to ask whoever you got the car from because that makes no sense.

 

Yea they are actually diatechs. How ever u spell it. Stockers drilled out. So they are 550s actuall flow rate is 583

 

323 at 9 psi? No.

 

.........yes.... Don't be jealous.


Well none at the moment so don't get to jealous yet. Waiting on new mani and injectors
