BobsZTwins Posted March 30, 2004 Share Posted March 30, 2004 I'm still trying to work out everything to allow me to set my Turbocharged 350 (an original Scarab kit) back about 1.5" and down about 1/2" to the JTR level. One thing is still in the way. The turbocharger oil drain line feeds into the mechanical fuel pump base plate to the rear of the pump. Can anyone think of another place I can have the drain line feed into so I can eliminate the mechanical fuel pump and install a block off plate? I may be able to have a new drain line machined to feed into the block off plate at the very front but that may still limit my set back. Any suggestions? My other issue is with my 8" harmonic balancer. I'd like to replace it with a 6 1/2" but I've read differing views on wether you have to have the rotating assembly rebalanced as a set or not. I wouldn't think so, the stock ones go bad on occasion and I know people don't get the engine rebalanced every time! Is there a consensus on this out there? Thanks guys!

Turbo Meister Posted March 30, 2004 Share Posted March 30, 2004 My oil drain lines from my Z's twin turbos, drain into either sides of the oil pan. I drilled a large hole near the upper front side of the pan and had someone weld a pipe thread bung at that spot. Then I screwed the drain fittings into the bungs on both sides. I noticed your turbo is on the passenger side but you should not have a problem snaking the drain down to the pan even if you have to bring the line forward and then return to the pan. As for the dampner, I dont think it matters for balance purposes what size it is. I'm using a 6 1/4 dampner for my internally balanced 383 Chevy but I could have used the 8" one for more dampening effect. However, with my modified setback position the smaller one clears better. Good Luck, Hanns Quote Link to comment Share on other sites More sharing options...
BobsZTwins Posted March 30, 2004 Author Share Posted March 30, 2004 Hanns, Thanks very much for the feedback, draining into the pan sound like the way to go. I'll have to go with a smaller diameter dampener because of the steering rack interference like most set-back setups. I'm just glad I don't have to rebalance the thing! Thanks again!
