+20 injectors

[motorhead153]

i've got and 88 shadow es with 2.2l turbo 1 i got my hands on some +20s and the damn thing wont go past 3500rpm it just starts coughing spitting and smoking around that rpm i'm thinking the thing is just getting to much fuel or am i just crazy, has any one else had this problem out there?

I would put the stockers back in or get an adjustable fuel regulator, you need the lower the fuel pressure with those in a stock application.

Or get a BMW/Volvo turbo fuel regulator. They are set at 36 psi, and should flow those 42# injectors to about 35#'s. If you don't believe me, check out Gus Mahon's site about adding fuel.

I picked one up on ebay for $25 brand new.
