thanks trying my best

Manifold looks a lot better the second time around. Got the throttle bodies fully assembled. Fuel rails installed. Also, got some wiring done on the coils. What a pain in the ***!!!! Got all the injector clips pinned, AIT, Water Temp. Now all I have is to wire up the CAS. Does anyone know what I am supposed to do with the bare wire that is in the shielded cable for the haltech flying lead harness? Do I ground this wire or just leave it be?

Here is what the wires inside the shielded cable look like. What do I do with the bare wire that is in the there? Do I just wrap it around the other wires or does this get grounded?

That wire should be grounded via where it goes into the ecu itself (you shouldn't have to make your own ground).

Then on the actual sensor side it just stays in the insulation of the wire and doesn't connect to a pin on the plug. I don't have a haltech, but that is also how my coil wires to the ECU are shielded.

thanks, you are right....i reached out to Haltech and they confirmed the wire is grounded at the ECU and it does not have to be connected or grounded to anything on the CAS side.

that was the original intent when i bought the truck but my pockets did not agree with it. after a year of saving and getting lucky breaks on the price of some major parts, i took on the challenge........i will let you know if its been worth it. i missed some good driving weather hear in FL. my truck was running perfect when i removed the engin...in fact its in my freinds dad FB. he lives by my house so i get to see him zoom by my house with the old REPU engine all the time

it’s been a little more than 6 months and I have finally hit one of my milestones of the build. Yesterday I pressurized the fuel system and everything is leak free! It wasn’t without a lot of trouble shooting. First I could not figure out why my fuel pump was not turning on? Started at the pump and found no power. Checked the fuse and I had power. Something between the fuse and the pump was shorting….what I didn’t remember is that the pump runs from a hidden kill switch!!!! That took about an hour of troubleshooting. Once I turned on the switch, the pump pressurized and I had pressure. After a brief inspection I find a leak coming out of the top of the fuel tank….dropped the fuel tank and found the return hose to be broken.

That fixed and pressurized the system and hoary!!! No leaks!



Also installed the oil cooler and oil cooler lines. Installed radiator and fan. Went to install the starter and found that Autozone had ordered me the wrong one! Back to the drawing board on that one. Just waiting on my spark plugs, an injector clip and my MSD wires to arrive, all of which should be by the end of the week. Lastly, I didn’t like how the velocity stacks came out. The inside was not polished. I decided to have the inside anodized in blue like the pulleys and leave the outside chrome….lets wee what that looks like????? In the meantime, this is how I left the engine last night.

Question about your radiator overflow can. Does it have the ability to suck coolant back up or does it just dump it to the overflow tank?

Sorry if I missed it, which Haltech are you running?
Congrats on the startup, it sounds awesome.

If you ever move to another project I call dibs. Not messing around.

Damn Simon, you aren't messing around. That sounds great! Gotta get a ride in it at DGRR. Very slim chance mine will be done in time so it looks like I will be rocking the father-in-law's BMW Z4.

Finished up some things over the weekend. Got the rear end cover on and had a one piece driveshaft made and installed. Also, filled up the tranny, installed short shifter and filled up the rear end with fluid.

Also re-wired the fans. I had a fan controller and I think it was on its way out. Since I now have the option of running the fans from the computer I ran them from the computer. Here is what they look like installed.

Lastly installed the throttle cable, cleaned up some misc wires. Here are some pics over all. Hopefully next week take it to the tuners to get a good base map installed and start putting some miles on her.

you know as a true car person and rotor head I truly love all my personal cars so when its time to part with one you always wonder if the person buying it is the right person.......................

Well, I can truly say that you have knocked this one out of the park! This is the dream repu I told you that I wanted the day we were loading her up on your trailer! Job well done my friend simon.
After I sell my FD, now with 41K original miles, I will have to look and find another repu to build its twin.

Keep up the awesome job Simon.
