get the ebay kit, and dont get extreme with it.. and u will be ok. My old car had ebay manifold/ turbo.. and the manifold welds cracked, but it was expected b/c it was stainless steel. but it was reinforced, and hasnt had a problem. And the turbo hasnt leaked a day in its 14lbs life...uget the ebay kit, the rest wouldnt cost u that much you would probrbaly spend most on getting the motor to handle the boost more than anything. i think u shold keep saving for a k swap..and be alot more reliable
