Hey i just turboed my 420a about 2 months ago. My motor has about 170,000 miles on it. I've got a t3/t3 turbo with a .70a/r compressor housing and a .48a/r turbine housing, I get about 8-9 p.s.i. at about 3800-4200 rpm's. I have absouletly no fuel management, all it is is the turbo and the fmic. It is externally wastegated, i have a 4 pound small yellow spring in it but some how get 9 psi?
Weird idk, I heard external wastegates don't spike, if so, why am I spiking so bad? My motor still runs fine except when I blow my intercooler pipe off like once every other day.
When you guys turboed ## car did anyone notice their idle surging before coming to a complete stop? I idle at about 1800 rpm's until i come to a complete stop. Thnx for any help guys
