Which sizes are people running for replacement oil feed lines for the greddy tt kit? -3an or -4an? Thanks

 

did you ever find out from anyone?

I was thinking about changing my greddy oil lines soon.....they've been on for about 3 years now!

 

i have had -4 for several years with no issue yet... IIRC the turbo has an oil restricter built in? HKS also sells 1/8 BSPT to either -3 or -4 fittings... I can recall which size... but anyway, they have built in restrictors and come in one size for journal bearing and another size for ball bearing.

 

Well I was leaning on going with -3 an. The ID of the hose greddy supplies looks the same size of a -3 an hose, but the hole in the banjo fitting looks similar to a -4 an hose. I think I am going to do a little more research, thanks for the input phunk, your post may have me go with -4 an, what size return are you running? I plan on using -10 an for my returns.

 

What size does Forged use in their upgraded Greddy Oil line package?

 

I'm using size -4 AN
