    That's a good start RobertC. I think you can do it completely with your own ideas.

    Robert - I only now listened to your exhaust note. Sounds just great. I can imagine your satisfaction. Well done!

    It's called "friction tape" and you can buy it all day long at home depot for like $3/roll. It's also popular for hockey sticks.

    Don't have a great picture, but he's some I did with home depot tape:

    Just got it back from the exhaust shop today and it sounds great, the engine sounds great and it is running very well now after some electrical issues.

    2 Into 1 and a secondary O2 bung soon to be filled with a Wide Band.


    Mid-Section, Magna Flow Resonator to kill the rasp.


    Up and Over the subframe with a flange so the exhaust can be removed in 2 sections.


    Magna Flow Roundy to give it some tone. Check out the cool oval tip.



    You want to hear it? Click it and turn it up, sounds pretty good.

    this is how the afm was mounted on the M2 i took apart to recreate. it is a thin brackedt that bolts on end of stock afm and attaches to inside fenderwell.




    lots more pictures of my my before, during and after disassembly at:

    Yes.., I thought the gauge in the pic further up the thread was fuel pressure. There was a paragraph discussing that there was work being performed on the fuel system.

    Sorry about that !

    And why is something not right? Plenty of people use a 3-Bar FPR. Are you confusing this with his Oil Pressure readings?

    Just curious.
    Using the stock 3bar.


    IT RUNS!

    Sounds good, responds well but can't really run it due to no coolant as our upper pipe was delayed. Either way, I am happy as this was a significant investment of time and money. Has 65psi on the mechanical oil gauge.

    Well been in custom wiring hell for the last few days. I am simply going to copy and paste my updated posts from another board as I have been making progress.

    Yay, yet another day of fun wiring, made some huge progress. At this point I should have all the wiring done in one more day. All that is left now is body wiring. This would be the gauges, tach wire to C104, make the C101 mating connector, and redo the body harness in the engine bay.

    Then its on to fuel system which is about 60% done already. I got some pipes to put on it to get it fired up and driven over the the exhaust shop.

    I am waiting on a couple other parts but hope to have this thing done by the end of the week.

    Well its late and I want to go home and eat, so this will be brief with just a few pictures.

    C101 bracket and the speed and reference sensor bracket are installed.


    Diagnostic connector, O2, coil, ecm, relay power, ecm grounds, all routing and placement of the engine harness is DONE!


    Got the oil sending unit relocated. I used braided BMW hose as a protector against the chaffing of the stainless weaves on the paint, brake lines, or wire harness.


    Today only got a few hours in on it.

    Got all the hoses for the IVC and the vapor hose's, so thats it for the engine, Only left to do is install the intake plenum.

    I still need to clean up the stock wiring on the drivers side, its a mess. Today I cut out a DIY main harness patch cable. It was only 12g on a 10g wire. I cut that out and upgraded it to a 8g cable, it is the main power feed to the harness.

    Then the DIY battery cable end was only held on by a single crimp, this is the main battery cable.

    I made new ends using non insulated heavy gauge ring terminals. I take the ring fitting and turn it upside down so the cup is up, then using a mapp gas torch I melt solder into the cup, insert wire and let cool, done. That connection is not going anywhere, then back it up with the proper size shrink tubing to seal and add pull strength to the connection.

    I did this for both cables. Then since the cables travel right under the plenum I wrapped them up tight with a few layers of the fuzzy tesla tape.

    Tomorrow I hope to finish the engine bay wiring for the C101 connecter, get the plenum bolted on, tackle the VDO gauges and some interior wire connections.

    Then its only fuel lines and a few typical loose odds and ends. Hoping to fire up and break in this weekend!!!!!!

    Just 2 pictures for the night, oh ya, in the process of doing the main battery cable I managed to stick my index finger right into a puddle of hot solder. Oh Damn, Roach Burn! lol

    Main Battery Cable


    Both main power cables installed and wrapped. You can see the old brass one was not very secure.


    I got some steaks to go cook so I am out of here,

    C/YA,

    Alrighty then, in the last couple days I have all but finally finished all the wiring on this car. Jebus, I have been in electrical purgatory and am finally cleansed and purified, amen to the wiring gods, lol

    Anywho, got the C101 connector done, also at the last minute figured I should do something about the electric fan. I had a old fan relay kit I never used so figured it would be perfect for the project. Its Chinese, so I only expect it to be temporary but it sure beats having a flip switch in the cab.

    Got the engine to crank over and was looking for oil pressure. Last night I was getting concerned as the electric gauge was acting funky and I was not getting any pressure. After 6 trys, I figured it would be best to leave it alone and tackle it in the morning. I removed the sending unit and cranked it over and got some oil out of the line, maybe a air pocket got trapped and would not allow the pump to pick up oil? Either way hooked up a good old fashioned mechanical gauge and viola 58PSI!

    So today I will be working on the fuel system, and a couple odds and ends. Still got to figure out how to mount the AFM as it has NO mounting holes in it. Its the first time I have seen that, so I am assuming we will build a 'shelf' for it to sit on. Not sure.

    Alright a couple pictures and I am out of here and back to work. Oh ya, last night I got the 'Why wont the engine crank over?' syndrome. Duh, did we forget the engine to frame ground, DOH! lol

    C101 completed


    Fan Control Relay Installed


    56psi confirmed on a mechanical gauge, WYSIWYG


    It will be interesting to hook up the electrical and see if I get the same number on the VDO gauge.

    C/Ya



    So far so good, hope to fire this bad boy up this weekend. It kicks hard on every stroke when cranking it over so I know this S14 is timed, primed and ready to rock!

    [peace]

    Remote mount the oil pressure sender. The S14 vibration kills them. In roughly 2-3K miles it will fail and start sending you strange readings that will scare the crap out of you.

    I too prefer the simplicity of the direct mount, but I killed 3 or 4 senders before I gave in and mounted them on the fender fed by a pressure line.

    Many underestimate how destructive the S14 vibration is.
    Thanks for the tip. I am aware of the vibration factor, a remote line kit is on the way. Had a M42 break a oil pressure adapter from vibrations in the first couple hundred miles also.

    At this point I am just trying to get this thing up and running.
