Datsun#1 Posted September 12, 2014 Share Posted September 12, 2014 Hey Zers! Well its come time to turn my stroker 280zx into a stroker turbo..right now i have 10:1 CR. I plan to install forged J.E Dished pistons and a 2.5mm HG. this should bring my comp down to a low enough leval to turbo charge.my biggest concern is going with an aftermarket EFI..im running tripple 44 mikunis right now.im thinking of using the N42 non-EGR intake manifold and a 70mm TB.greedy boost controller.Megasquirt 2,MSD 6-2.t3/t4 turbo,720cc injectors.blow off valve/waste gate etc..im wondering what sensors are needed to use megasquirt for my fuel control only.am i able to use MS for fuel only and use MSD 6 for my spark control? if this works,can someone please give me a short write up as to how to go about setting this up.im pretty new to EFI as i grew up with carbs (and im 21). Please,any insight on this would be great. P.S- I plan to run 17-20lb boost MAX! thanks~ Randall Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 12, 2014 Share Posted September 12, 2014 The DIY site's a pretty good source. http://www.diyautotune.com/tech_articles/how_to_megasquirt_your_280zx_turbo.htm http://www.diyautotune.com/tech_articles/megasquirt_install_writeups.htm Quote Link to comment Share on other sites More sharing options...
dexter72 Posted September 12, 2014 Share Posted September 12, 2014 You should also get a wideband setup so you know what your afr's are. Why don't you want megasquirt to control your ignition?. It is a full Standalone unit. Quote Link to comment Share on other sites More sharing options...
Connor280ZX Posted September 17, 2014 Share Posted September 17, 2014 If you plan to use a stock manifold, you will need to do alot of porting in the plenum neck, and intake runners. Otherwise that 70mm TB will be pretty much useless. Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 18, 2014 Share Posted September 18, 2014 (edited) Strip out the venturis of the Mikuinis, buy some screw in injector bungs and put them in your existing manifold, make a matching Fuel Rail, and buy the TPS Adaptor for the Mikuni Body, and run what you already have. There are articles in Japanese Magazines doing this on dyno tested engines to see what they get, and they always get more! And the look in the engine bay is awesome. tone down the Injector Manifold and injectors painting them black and it looks like a vacuum rail... everything looks like your carbs are running, not EFI!

Tony D Posted September 18, 2014 Share Posted September 18, 2014 Now, about this: "im pretty new to EFI as i grew up with carbs (and im 21)." Uh, I'm 50 as of Friday. I grew up in the UP of Michigan. I truly grew up on carbs, and saw the transition to universal EFI. I watched domestics cling to old technology and imports embrace change. If you really did grow up on carbs, you would be RUNNING to EFI! I would NOT recommend turbo on your Mikunis, regardless of your 'growing up on carbs' comment. I would, however highly recommend the turbo blow-through ITB setup I describe in the prior post. The fueling will be FAR easier than with carbs. Search on Blowthrough Mikunis, and you will see! (You don't HAVE to go to EFI when you go turbo, but I'd highly recommend it!) Quote Link to comment Share on other sites More sharing options...
