Ok. I plan on mounting a precision 6262 and I was wondering if I can get some help on the oil feed setup for the turbo. Can someone point me in the right direction on thread pitch for the block and length of the line I'm going to need. Also another part I'm confused on is whether I need -3 or -4 for the turbo feed line. Any help is greatly appreciated.

I run a PTE billet 6262 journal bearing on my RB25. I can't remember what thread pitch the -4 adapter for the block is, but Raw Brokerage sells them. I used one of these flanges for the feed and pretty much the same thing for the return with a -10. http://www.atpturbo.com/mm5/merchant.mv ... y_Code=FLG

Here is a link to the block adapter fitting on Raw Brokerage's website for the feed. http://www.rawbrokerage.com/earls-4an-e ... rb25-rb26/
Now for the oil drain fitting, you will need a 3/4"NPT to -10 90degree. You can get those from Summit or Jegs. As for the length and the hose ends you'll need, that will depend on your setup whether you need 90's, 45's etc.

How much power are you making with your turbo and when do you see full boost?
