[QUOTE="98cobra#1222, post: 14835669, member: 125489"] Not to many updates, this last month has been put on hold waiting on v band clamps from RPS. The clamps that came with the on3 kit were/are impossible to get on the hot pipes. I was able to get some small tasks completed while I wait though. First up was punching the oil pan for my turbo oil return line. Items used: 1) Hammer 2) Punch set 3) 3/8th NPT tap 4) All purpose grease 5) magnet 6) 3/8th to -10AN fitting 7) Oil drain line First step was to remove the paint from the oil pan and make out the location of the hole. I used the directions from Vortech that can be found here: [url="http://www.vortechsuperchargers.com/images/7.pdf"]http://www.vortechsuperchargers.com/images/7.pdf[/url] specifically page 12. After marking the oil pan I used a small punch to start the hole and then stepped it out to the final size using a 17/32" punch. [img]http://s26.postimg.org/m85k3i7ex/Turbo_Oil_Return_1.jpg[/img] [img]http://s26.postimg.org/w2wp9qbd5/Turbo_Oil_Return_2.jpg[/img] Once the hole was punched out with the 17/32" punch I packed the flutes of the tap with grease to catch metal shavings as the tap cuts the treads into the oil pan. This process took some time as I cleaned out the grease and replaced it with new grease after a couple of turns to be sure no chips fell into the pan. I also used the magnet to clean out chips that were left in the threads. I will run oil into the drain hose to flush any possible chips down and out of the pan before I fill the engine with oil for start-up. [img]http://s26.postimg.org/sbn4nexop/Turbo_Oil_Return_3.jpg[/img] I then threaded in my AN to NPT fitting and test fit my half assembled oil drain line, to be sure I had clearance between the oil pan flange and the fitting so I could tighten it. All seems good with around a 1/8" to 1/4" of clearance between the AN fitting and the crankshaft pulley. [img]http://s26.postimg.org/s0a9oe6mh/Turbo_Oil_Return_5.jpg[/img] [img]http://s26.postimg.org/8d79l1czt/Turbo_Oil_Return_6.jpg[/img] Final step was to paint the bare metal around the oil drain fitting with some semi gloss black. While I am still waiting on v bands to ship I decided to mock up the hotside with the clamps I have, that are to shallow. I put the hotside in and turbo on to measure for the oil drain line and assemble the rest of it. I was also able to finish installing the fuel injectors and fuel rails. Had to cut down the intake manifold bolts, the ones used to retain the wiring harness clips, to let the rails fully seat the injectors. Turbo oil drain finally fully assembled. [img]http://s26.postimg.org/7ajrgn6yx/IMG_2445.jpg[/img] Turbo hot side mocked up. [img]http://s26.postimg.org/unhsz5n2h/IMG_2447.jpg[/img] [img]http://s26.postimg.org/cn8luruvd/IMG_2443.jpg[/img] [img]http://s26.postimg.org/d8xkqvpxl/IMG_2444.jpg[/img] I still need to move the radiator forward, I am trying to figure out a way to retain AC if I can. I never really use it so if I can't it's certainly not the end of the world, but with a black car and black interior it can get really uncomfortable really quick without it. Has anybody moved the radiator up about 1/2" or so and also kept the AC condenser? [/QUOTE]
