DATN510 Posted December 17, 2011 Author Report Share Posted December 17, 2011 Whats up Ratsun, been busy working that's why haven't posted in a weeks. so now I'm back at the EFI mani build. Unfortunately when I went to a local Fab shop with the dimension to punch my Plenum cover they didn't get the spec's correct. Lesson Learned. And decided to do it my self. I took all if my material to my friends shop and not to mention where my wife works Where they have a full machine shop and that everyone that works their is cool. I bought my own pip e to bend the Plenum cover and went to work. Press time After templet mark up and cutting on the dotted lines. Its coming together nicely. Have more pics coming.

DATN510 Posted January 8, 2012 Author Report Share Posted January 8, 2012 Hello ratsun forum, does anybody have a L series head that lives near Escondido that I can barrow for my EFI mockup.? Please Quote Link to comment
DATN510 Posted January 8, 2012 Author Report Share Posted January 8, 2012 Also need help on what kind of throttle body to go with for this application? Thanks. Quote Link to comment

ggzilla Posted January 11, 2012 Report Share Posted January 11, 2012 Some guys use S110 throttle body, from a Z20E. It looks similar to the 280Z version but is a 2-throttle version. Quote Link to comment

So I have been working hard on the fuel injection plenum and here is what been done. Pictures Don't do this plenum justice,I can see the dream coming true. I already have the megasquirt system and turbocharger ready to go I just have to order it. Now I have finally had the money to order fuel injectors and bungs. And I started working on getting the bungs cut. I got 2 of them done it's just stressfull cutting and getting them all perfect, so far so good on the 2.

DATN510 Posted June 15, 2012 Author Report Share Posted June 15, 2012 Hello dimershow is everyone? I hope all of you are doing well. Just giving everyone an update on the efi progress which is going a little slower then I wanted, but got to work. So here is where i'm at. I got the fuel injector bungs welded on Then I got started on the fuel rail, With a lot of problems The short version is using a drill bit not ment to drill bung holes (ha ha that was funny). And I saved the money ($140) for the special drill bit. So after all the trial and errors I got it right, and even tested it at 40 psi SO I taped the ends and installed the nt's, and did a little polishingto see how she would look. I also picked up the megasqiurt ecu complete set up. And also picked up a T3/T4 turbo charger kit with intercooler. I will send more oics soon. Here is a oic of hallie out on Grand in Escondido on Friday night. Me and my good friend Eric go park and show off our cars which is a lot of fun. I am stuck on a few things maybe some of you can help? Has ant of you installed a megasquit (MS2) on a 510? I have everything I need. im using my dizzy distributor. So if anyone has any input would help. Thanks. Mike 1 Quote Link to comment
ggzilla Posted June 15, 2012 Report Share Posted June 15, 2012 Icehouse has used Megasquirt on a zillion 510s. Last one I saw he used it on a turbo L16. Quote Link to comment
DAT510 Posted June 15, 2012 Report Share Posted June 15, 2012 Lol what do you mean dizzy distributor? Quote Link to comment
ggzilla Posted June 15, 2012 Report Share Posted June 15, 2012 You'd get dizzy too if you spin around like that You can use Megasquirt with just about any distributor. For Megasquirt EFI control you just need a tach signal Quote Link to comment
DATN510 Posted July 11, 2012 Author Report Share Posted July 11, 2012 Hello fellow ratsuners how is everyone? Well I've been working on the EFI plenum and got to a point where I will need some assistance from you? But for now I'll show you the progress I have completed. First I took off the dual webers. Purchased the megasquirt 2 and the turbo charger kit. I installed the EFI plenum to see how it would. With the air cleaner. Then I took the plenum to my friend daves shop to get the rest of the plenum welded like the TPS flange, fuel rail brace that I made from the leftover material and throttle brace. Then I installed the megasquirt through a new braided harness. I decided to mount the ECU and relay under the dash to keep it hidden. So I spent a lot of time running the wires through a small peace of braided tubing to make it look clean and I had to rework the air filter because I did not like how it fit. I also ran the plenum hose through the fire wall with the fuel injector wires. So here is the finished........ well almost finished product I still have to polish all that aluminum. Here is where I decided to put the filter for now. So here is where I need help I believe I hooked up all the wiring to the MS2, Unfortunately I cant get her running. First I'm using the 620 distributor that has the little black box on the side, and inn the megasquirt manual says it will work with no problem. But I'm having a problem. Second I have no spark at the plugs when grounded to test but I have power to the coil. Here is how I have it wired, on the megasquirt website their is a 280zx wire up with a similar install as mine. I also check a few more installs and they are the same. My dizzy has 4 thooth magnetic pickup with 2 wires coming out a green and red. I ran the red wire to the + on the coil and ran a separate wire( supplied by MS) from the - on the coil to the MS relay. Then out from the relay to the green wire on the dizzy that goes to the black box. So if anyone is familiar with this setup I would really appreciate it, and if anyone needs help let me know? I will post video when I get her started, and will send oics of turbo install when I get started. Mike Quote Link to comment
ggzilla Posted July 11, 2012 Report Share Posted July 11, 2012 the 620 distributor that has the little black box on the sideYes, it will work no problem, as many people have made this Matchbox distributor work. It is totally independent of the Megasquirt. * Check to make sure it has 12V at the coil *when* cranking * Check to make sure the distributor Blue wire is connected to Coil- * Check to make sure the distributor Other wire is connected to Coil+ My dizzy has 4 thooth magnetic pickup with 2 wires coming out a green and red.I ran the red wire to the + on the coil and ran a separate wire( supplied by MS) from the - on the coil to the MS relay. Then out from the relay to the green wire on the dizzy that goes to the black box. Wait ... the red & green wiring coming out of the distributor should NOT go to the coil. They should go to the black box (terminals that face inward). The terminals that face up normally have a blue and other color wire. Those go to the coil. Megasquirt just connects to Coil- terminal as a tach input. Otherwise the "matchbox" ignition has nothing to do with Megasquirt. Quote Link to comment
DATN510 Posted July 11, 2012 Author Report Share Posted July 11, 2012 So I just leave the wires coming out of the black box as they were and connect the tech wire from the relay to the - on coil? Got it thank you! What about the setting in the tunerstudio? Quote Link to comment
ggzilla Posted July 11, 2012 Report Share Posted July 11, 2012 I haven't used tunerstudio, but the Megasquirt doesn't need to know about the distributor type. Setup MegaSquirt for a "fuel only" mode. Quote Link to comment
ggzilla Posted July 11, 2012 Report Share Posted July 11, 2012 This is how you wire the Matchbox distributor to work. Factory distributor wires for Matchbox are blue and black-with-white-stripe. These two terminals (top facing) go to the Coil 1 Quote Link to comment
ggzilla Posted July 11, 2012 Report Share Posted July 11, 2012 The 280ZX info you read might be about 1982-1983 280ZX Turbo, which is totally different from earlier Z-cars. With the 1982-1983 Turbo you can do MegaSquirt spark control. But not with the 280ZX that use the black box (Matchbox) distributor. Or Datsun 620 or other Matchbox distributor -- as far as I know. But my knowledge is a couple of years old on the Megasquirt stuff (MS-II). If you want I'll look over the info and give you my take on it. Oh, and ... nice photos. Quality work. 1 Quote Link to comment
DATN510 Posted July 17, 2012 Author Report Share Posted July 17, 2012 Thank you for the info on distributor, nothing got fried. I got the car running with pour idle and when I give here gas she dies. I'm still trying to figure megasquirt out, due to my engine not being stock makes things more difficult to tune. But im getting there. Im pretty sure that its a fuel issue, timing is set to 10 degrees and still have to get lc-1 o2 sensor configured. so I'm on the right track. If anyone has advice and is familiar with MS2 let me know. thanks, Mike Quote Link to comment
Rustina 510 Posted July 17, 2012 Report Share Posted July 17, 2012 Once this is done are you going to make more? It's pretty Quote Link to comment
DATN510 Posted July 17, 2012 Author Report Share Posted July 17, 2012 Yes I will make more. if you wants one let me know? also what does everyone think its worth? I also need to upload oic of Plenum after 8hrs of polishing. Quote Link to comment
