$2008 GRM Challenge – Turbo AWD Mercury Tracer LTS

Running out of time, but not things to do.

I'm still making headway and really haven't hit any snags. Everything is going back together. Most importantly, the engine and transmission as well as the axles are installed. The suspension is finalized, short of an alignment, the engine has been cleaned (for the most part), a pimpy eBay special 6-puck clutch is installed, the brakes and clutch hydraulics are filled are bled, the shifter housing is painted and installed, the shifter cabling is finished, and the hand brake is installed and working. The car currently sits on 4 wheel and is looking pretty good, I might say.
Once the engine was in and the suspension buttoned up, a critical area of focus was the tie rod ends. With using the Capri knuckles, the BG tie rod ball joint assemblies happened to be too long resulting in about 2 of toe-in with the tie rod ends adjusted all the way in (wow, long sentence). After much searching, I finally found a spherical rod end with the proper thread diameter and pitch (it seems female M12x1.25 ends are hard to come by). The rod ends are about an inch and a half shorter overall than the stockers allowing the full range of adjustment. I fabricated spacers for each side of the ball to prevent binding. The end result worked perfectly.

Moving onward to new material, I've finally started constructing the turbo manifold. I originally wanted to build a manifold with equal length runners, but with 3 weeks remaining, that just isn't going to happen. I fabricated the head-side flange back in January before the project even really started. I'm glad to have that part out of the way considering the amount of time that took alone. Using weldable gas fittings, I constructed a log type manifold on to it. I used a wrecked head I had lying around to weld the assembly. I still have yet to place the flange...that'll happen tomorrow. Fitting a T3-series turbo between the engine and the radiator on the BG is more difficult than I thought. It's pretty tight in there!

post 162, picture 5 reminds me of this

I think you're gonna have some back pressure issues. :p
 
Continuing the turbocharger install.

I completed the turbo manifold today. My back is killing me ;). The turbo doesn't weigh much, but when holding and positioning it to get just the right angle while bending over will where you out. After much tweeking and swapping the water pump inlet pipe with one from the GTX engine, I got everything positioned just as I wanted it. I had to use the GTX's inlet as it was quite a bit shorter and allows just enough clearance for the turbo inlet. This Thunderbird T3 seems to have become much larger when fitting it into this car. It sits about an inch from the engine block and about a half inch from the radiator. Whew! I used a mock turbo with the mock head to do most of the welding. Expendable parts are always cool to have.

After the manifold was completed, I began construction of the down pipe. This too went fairly smoothly and the only hangup was fabricating a flange to mate with the waste gate housing. Ideally, I'd have used an external waste gate with proper piping, but again, the lack of time prevented that from happening. The outlet of the DP is just at the back side of the engine and I'll likely throw on a resonator and turn-down pipe. While I was at it, I welded in a bung for an O2 sensor and called it a night.

Tomorrow will consist of bolting on the real turbo, installation of the intercooler, and all of the piping. Following that, the next day, I hope to finalize the fuel cell and maybe even crank the thing. Unfortunately, I don't have the dashboard in yet, and therefore the steering wheel, so driving it will have to wait a little while.


Onward to pics....

wow, talk about some serious progress. If I'm lucky I'll be up there later this week to lend a hand / heckle ;)
 
Lookin good! Can't imagine the amount of time you must be putting into that but with the way it's coming together, it should be totally worth it!

(bowdown)Craziest BG build I have ever seen!(bowdown)

If you're ever up in WA, I'll buy you a beer! (cheers)
 
Dam kevin.. didnt know u had that much skill with the flame and metal...lol

Is that a all custom log manifold? or a log kit?
 
This is what i call an Insane Modification to a car... wow buddy your work is priceless, i can't wait to see the final product done !!! Congrats !!!
 
wow, talk about some serious progress. If I'm lucky I'll be up there later this week to lend a hand / heckle ;)

Yeah, I have a bunch of off hours work to do this week, but I might have to swing out this weekend and help you break a couple things. :p
 
Thanks guys! It's been a ton of work and, at times, I wonder if it's worth it. But it's been fun and I can't wait to hear worthy noises coming from it. :) I really do appreciate the compliments though!

I made the flanges earlier this year. The tees and ells are weldable gas piping that I cut to fit. They're pretty thick peices.

Just let me know, we'll figure something out :)

Intercooling

I made a bit of progress with the intercooler and piping this evening. As usual, things don't happen as quickly as I'd like. Nonetheless, progress is progress.


I began by fabricating a bracket to mount the IC to the lower rad support mount column (or whatever it's called). There were two tapped bosses already there to mount a bracket to without having to drill anything. With the bumper in place, I set the angle. I was forced to angle the IC for two reasons. A) to allow the in/out piping to clear unibody members and B) to maximize the lower bumper openings. I think the arrangement will work well. I secured the IC with a pair of aluminum brackets at the top yielding surprising rigidity.


After the IC was set, I began the piping. I cut a hole in the sheet metal just above the driver's side port on the intercooler and used a 90* silicone coupler to point the piping into the bay. All of the piping is aluminum with the exception of the bend going to the throttle body. Since I don't have the capability (yet) to weld aluminum, the steel bend at the throttle body allows me to weld a port for the IAC feed line and BOV. As a side note, I hate the fact that all of the couplings are red. It was the cheapest thing available on eBay and really makes for an eyesore. I doubt there's much I can do about it at this stage. Oh well...
