383 240z Posted June 5, 2007 Share Posted June 5, 2007 OK I put a MS on my Jeep as a test unit for my Z. I would like to let the MS control the spark, but I've been having a lot of trouble with it. So I put a GM HEI and a MSD 6A in and I got it kinda tuned. I'm now ready to tune it past the Idle portion, I've now run into a block, I went to hook up the Vac. Advance, and I discovered that the Jeep intake and TB has no provisions for ported vac. I've been thinking that if I bore a hole just above the TB's blades and thread a nipple into it that would work, is there anything else I need to think about? Thanks for any help you might be able to offer. Keith Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted June 5, 2007 Share Posted June 5, 2007 I suspect that would work OK - not quite as well as real ported vacuum, but very close. Quote Link to comment Share on other sites More sharing options...
