Hey everyone!



i have fitted a skunk2 manifold to my b18 engine and a turbo, but there was one pipe left over from the top of the radiator outlet pipe.

its on the top of the outlet, and i think might supply the IAC valve and the throttle body with water, but ive snapped the pipe
it didnt go to anywhere after fitting the skunk2 manifold, so can i just tap it and screw in a bolt?
is this water feed pipe needed for the IAC valve?



ive highlighted it in red here:


thank you
james

 

Are you planning on using the stock throttle body?

 

yes, you can. It is used to heat the TB and IACV in the cold winter. It is not really needed for race cars.

 

Thank you I will block it off, I am getting an iac error code in hondata and it won't idle, and I read on here about people having idle problems with no or low coolant in the system. I've cleaned out the iac followig the hondatech guide but it didn't work, it ran perfect In the Honda.

 

Hi yes standard throttle body for now, it going to be my daily driver and it gets c
very cold here in winter

 

low coolant or air in the system may cause idle problems but will not cause code 14 (IACV). you should look into the wiring or the iacv itself

 

hi dpetro1!

thankyou, ok that is great news, ok i will block this pipe up,
and i will check the voltages at the IACV, and probably replce it

than kyou
james

 

is that in an austin mini?

 

Hey yes it is a 1968, this is the third time I've full rebuilt it, this is he biggest engine so far

 

check if you didn't invert Iac plug with Iat plug or evap canister Plug
they are both close to each other
