Walbro 190hp & RB20 injectors in and running perfectly!
 

They are 270cc injectors (the same as the ones found in a SOHC KA24).

I had to hacksaw the bottom keyway off (it is offset and on the connectors I had it was in the center). Easy enough.......

I also had to change the connectors on the harness (quick disconnect style I yanked of of a saab at pick-n-pull). Soldered and heat shrinked by my friend chris :)

MAKE SURE YOU USE THE MIATA O RINGS.....NOT THE NISSAN ONES....THEY ARE TOO SMALL!!!

I was going to use the 1.8's like everyone else.....but my friend had these laying in his toolbox. I payed 2.99 for new o-rings....that's it.....I think that is pretty good :bigtu:

This is a great option if you have friends that have swapped out a SOHC KA24 or are upgrading the injectors on their RB20.

I will try and take some pictures, but please feel free to ask any questions or make any comments. I think I am the only person on the forums using these injectors :cool:

sounds good....i thought the nissan injectors were sidefeed?

SR20 and DOHC KA are side feed

RB20/25 and SOHC KA are top feed :bigtu:

Did you get them flow tested?


Nice. 2.99 for injectors is a pretty good deal.

didn't get them flow tested.....that is the stock flow rating.....but my friend ran them at like 105% duty cycle on his RB before he swapped injectors :eek:

I know they work just fine :) He was making waaaay more power than they should have been able to support :bigtu:
