so we have a car with a -6? feed line whit no restrictor, it smokes if you let it idle longer than like 10seconds. could the feed line be too big?

is it a garrett or hks turbo.if so you need a restrictor that mounts on the turbo,then the fitting for the feed line.i used a -4 feed line to mine(HKS turbo)

its a turbonetics with an s4 center

Thats a BIG feed! I'm using a -4 with no restrictor to a TO4R..



I'd get a restrictor in there Mike. https://www.nopistons.com/forums/pub...IR#>/smile.png

yah i'm leaning that way

You're about to blow your seals, ruin your turbo, and incur great expense and labor, and down-time. Restricots are cheap and E-Z to install. What are U waiting for?

Just curious\, I dont' need one but where do you get them?

4-an....

-4 also

with T67-1

this is an old post, so I guess that using -4AN inlet and -12AN otlet for the oil should be fine right? I am going to be set up shortly with a to4r. My oil pump has had its ports enlsrged and the irons have been ported. plus I have increased the pressure relief valve spring by adding a couple of washers beneath the spring, on the new stock FD spring.

I would nt want any problems with a smoking turbo, apart fro the damage that can be caused since my oil pressure is quite high. I run 3 rotor main bearings thus i added the pressure.



Thanks guys
