got a set of twm 52mm itb's with no injectors.

they will be going on a stock motor, now what injectors do i or should i use?

they previously had rc injectors on a race motor...

any help would be sweet!

 

[regamaster]

you will need to find out what style of injectors the ITBs were made for.
RC makes several different types of injectors.

 

[jdmchop]

set up for non oem injectors, boch style

I would recommend a 550 injector that you can get from RC.
This will give you a little room to make some upgrades.

does RC offer Bosch sytle injectors?

 

[josh95]

get 750's and you will be golden

 

[regamaster]

yes they offer them.

750s would be fine too. but honestly may be to big. We run 1000cc in our
race motor and still have low D/C on race gas.

If you drop down from 1600cc to 850 or even 1000cc injectors, you might see some more power. The 1600cc injectors are hard to control properly on all motor cars. We tried it and made more power with a smaller injector.Not to mention it is easier to get closer to the target AFR.
