Jus tlooking for a rwkw figure of when stock injectors are getitng near 100 duty cylcle and when is good to change..

Is 200kw possible with them?

I got 190rwkw from my stock injectors.

i think i saw 200kw with mine stock injectors back in the day with a Sard fuel reg and a bit more fuel pressure.

what would u suggest for there replacement then wat size injector?

ive got a set of 550cc mazda injectors in a fj20 rail if its any good to you? $300?

Hey mate you still got those injectors on the fj rail?

200kw?? i dont think so!! my dr30 only got 160-170kw with more pressure
the injectors are only 370cc
my 2cents is go get aftermarket c18det ones (about 550cc) will be good to just under 300kw
bolt in:) no aftermarket rail needed just slide the fuel lines over and clamp it at both ends
but just like with any upgrade you !!will need a aftermarket computer!!

who else hear has used the ca18det injectors? wat size are they? and wat is better between the them and the 550cc rx7 injectors?

Have a search for injectors, I had a post for upgraded injectors.

I used 750cc supplied by rceng.com in the US, they were hose tail and went straight in using the stock fuel rail.

Worked out around $550-600 AUD delivered from memory.

Wrong!
CA18det injectors are 375cc. Pretty much same as stock.

read and understand before posting!! give people useful info or dont give any
i said "aftermarket injectors"

Your quite right sport. My bad.

On first read, the implication is use something "aftermarket" then "CA18".
Aftermarket is such a generic term it can be taken as ANYTHING not specific to an FJ20.
So it could be (and was) interpreted as second hand original CA18 injectors.
I think its excuseable to make such an error. Do you really need to such a ****en smartarse about it eh?
A simple correction would have sufficed.

The info about CA18 injectors is valid anyway, so can be of use to some people at a later date who might want a cheap set of replacement injectors for their stock FJ since 370cc Bosch top fed style hosetail injectors are very hard to find in that flow size S/H and are incredibly pricey new. (Think Bosch 036, 007, 024 and others) Go ahead and price them new. It will hurt.
10mm EFI fuel hose will push over the end with the o-ring removed and will clamp down nicely over the 8mm hosetail on the stock rail.

Pff.
