i dont know yet what kinda turbo i want as i wanne get the engine done first and then do the turbo.

the compression is 8.5:1 so for the return i go in the oil pan thats clear so fare but from where do you guys take the oil ? i think there are 2 options drilling and tapping the block or drilling and tapping under the oil filter housing

what would be better

I would just get a T adapter and screw it on the oil filter housing where your oilpressure sensor is thats the easy way no driling nothing.

+1 I agree with the oil pressure sender location.

I used this T from TRM its a quality peice but not cheap @ $30 it gives you a 1/8"NPT so then I just used a 1/8"NPT to -4AN fitting --> http://www.racersmarket.net/catalog/product_info.php?cPath=22_24&products_id=43

For the drain, just tap the oil pan and go. I used a -10AN to 3/8" fitting and tapped it into the pan. Easiest way to go is to do it with the oil still in so that you don't have to pull the pan, if you do pull the pan then I'd just do a welded bung.

The problem you'll probably have depending on your manifold + turbo choice is that the turbo is so low that you'll have a very poor gravity drain. I think I'll be buying a scavenge pump over the winter to make mine a bit better, my turbo sits lowso I have maybe 1.5" of drop, thats it. When you buy your drain fitting for your turbo, I'd try to find the lowest profile one possible, it'll at least make the best of the situation.

You drilled and tapped the oil pan and didn't pull the pan? Wouldn't that leave, say, a bunch of metal chunks in your oil? :?

Well im thinking the idea is while you're drilling with oil still in the pan once you gone through the oil in the pan will come rushing out taking w/e metal flakes with it.

What about the ones that don't? As much as I'd like to use this method, that sounds like a bad idea.

Well the idea is that as the oil came spooling out, the shavings came with it. truthfully I have no proof that there are no shavings inside other than the fact that my cars runs : ), I also ran 3 Liters of fresh oil threw the new hole I made (flush anything at all) before actually filling the car with oil again. I recommend pulling the pan, I'm sure its less risky, however I do know many people have done it my way.
