calpoly-z Posted March 28, 2008 Share Posted March 28, 2008 I just finished building my MS1 v3.0 and I'm in the process of gathering all the parts I'm going to need for the install. What I'm trying to figure out is if it would be worthwhile to use the MSD I have laying on a shelf or if I should sell it and use the money towards something else? I've already got some supra injectors (cleaned set of low impedance 310cc for $12 shipped to my door off eBay ), a 240sx throttle body and TPS, and the other sensors I need. An LC-1 is in the budget as well. My goal is around 300hp eventually on a recently rebuilt L28ET overbored .5mm and at about 8-8.5:1 compression. I'm still running the stock T3 on stock boost un-intercooled for now, but that will change soon enough. For now I just want the car to run reliably and as efficiently as possible. I've done lots of research on this and know the VB driver will run my ignition just fine, but I want to know if the MSD will give me any advantages in either my short term or long term goals. Any input would be greatly appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted March 28, 2008 Share Posted March 28, 2008 The MSD will give a more powerful spark; a VB921 is kind of like a middle of the road stock ignition module. Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted March 28, 2008 Share Posted March 28, 2008 Yeah i was having a spark missfire under boost and tried switching coils and it didnt get ride of it. So I tried putting a MSD 6L on and its worked flawlessly every since. Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 28, 2008 Share Posted March 28, 2008 If you plan on using the 82-83 distributor as a trigger source, and also to distribute the spark, then I would use the MSD you have. If you plan on doing a crank trigger with wasted spark, and COPs, then I would sell the MSD and use the cash elsewhere. Quote Link to comment Share on other sites More sharing options...
calpoly-z Posted March 28, 2008 Author Share Posted March 28, 2008 Thanks for the quick responses!! Looks like I'll be holding on to MSD to use since I am using an 82-83 distributor. Plus the last thing want to worry about is missfires under boost. Thanks again everyone Quote Link to comment Share on other sites More sharing options...
