we just installed a turbo on my dohc zc engine this weekend and I'm having problems with a few things, the turbo is hooked up perfectly and the plumbing is all good so there is nothing wrong there, its when im accelerating, I had it set a 8 pounds and it wouldnt do anything when I gave it gas, only when I was lightly accelerating, so we turned the boost down to 3 pounds and I can go hard into it but it cuts out and hitches and doesnt make any power, we changed the injectors to a little bit bigger size but that didnt make any difference,, when I floor it and it starts cutting out it sets off three codes,, 1 3 20,,, any ideas??????

 

do you have engine management? if stock computer do you have anything keeping the map sensor from seeing boost?

 

what about your fuel pump? do you have a high pressure fp?

 

you cannot just put injectors of a different flow rate, without having something to control it.

u need to look into some kind of engine management,
fmu setup, hondata, uberdata, zdyne.

 

I'm doing the fuel pump next, I was talking to someone who has a crx with a turbo and thats what he did was the fuel pump and a 1 way valve for his map sencer

 

u need to purchase what they call the missing link for the map sensor. It is designed for boosted engines so the map will get the right reading.

 

this is related so i figured id ask. I understand that boosting would add more pressure to the intake manifold and set of the map sensor but what exactly do you do to correct it. this missing link thing what is that? IM going Turbo ZC here in a few weeks so i need to get all the info i can. thanx
