CMonakar Mandeville 20B GT42R Project

Thanks. I am still making progress on the car, but I haven't had time to write about it because I've been pretty busy with my job. I'll post some new pictures this weekend.
The oil system is done aside from a remote filter mount. Mandeville is going to finish it next week. I had to re-engineer the secondary fuel rail a bit because the rear fitting made contact with the firewall. At the same time, I decided have -AN male mounts welded on, so I don't have to use NPT fittings. The gearbox is back together, and the Carbonetics push-pull conveter and clutch have been installed. This weekend my plan is to put the motor back in the car for the last time, install the driveshaft, turbo system, exhaust, and heat shielding.

Clutch has been installed. The nice thing about the push setup is you just mount it on the flywheel and attach the gearbox without having to tighten anything through the bell housing.
The motor is now back in the chassis. The power steering/AC needs some aesthetic TLC, but regardless it's great to see the engine back in the car !
Oil coolers (again). The goal here was to keep the lines near the top of the coolers without removing the 99 spec rebar, which does not have as much room inside as the us version. The best solution was to enlarge the hole going into the driver side frame rail and pass one of the oil lines through it. There is plenty of room in the opening near the top of the rail for the second line. The lines look rather long in this picture without the rebar in place. The key is that there are no sharp bends or any potential kinks.
T-Stat mounted using one of the stock holes next to the headlight cup. Just ignore that mess of electrical wires -I certainly am
Custom pedestal mount made by Mandeville to clear the transmission tunnel. I asked two other shops to make this part and they both failed. Mandeville cranked it out 4 days after receiving the request for LESS money. There is a reason professional teams pay for his work.
1/2 of the wiring supplies arrived. All the wire is Raychem DR-55. The red and white wire in the lower right is shielded. It will be used for the crank signal and ABS sensor signals. The ignition coil wires (not pictured) are also shielded. Due to the large gauge they had to be special ordered. The bag of yellow tubes in the middle are labels for each signal wire, so there is no chance of confusing them (EG Inj 1, Inj 2, Inj 3 ect). If you look closely there is also a very trick 32 pin metal mil-spec connector and 3 really cool (and damn expensive) sealed motorsports relays (grey/black) on the right.
Fuel pressure regulator mount. The goal here was to use a factory bolt hole and take up as little horizontal space as possible between the motor and the chassis to make changing the spark plugs easier. By mounting it sideways both return lines enter the regulator on the same vertical plane and the return port goes straight back to the return line mount on the chassis. I also replaced my -10 SX regulator with an Aeromotive unit which is basically the same but has -6 inlets instead of -10. This allowed me to eliminate the -6 to -10 adaptors and retain the gauge port.
In addition to all this I made some progress on a bunch of less exciting things like -reinstalling the pedal set, glass moldings, door handles, and custom driveshaft. Next weekend the goal is to finish up the oil and fuel systems (waiting for some fittings to arrive) and begin making real headway on the electrical system.

The harness is slowly progressing. I'm pretty much done with most of the power cable and I have laid out the sensor and injector wiring.
I am waiting for more materials to arrive. Once they come in I will be able to finish the ignition harness and the ECU sub harness.

Gotta love waiting on parts. Story of my life, honestly.
The build looks like it's going great, it's obvious you're busting your butt trying to get it done, but not rushing. Can't wait to see a video of the first start up.

Thanks.
Just how bad *** is the Pectel SQ6? Check out page 100 of the August issue of Road and Track to see what production car is using it. Here's a hint, the design team is made up of former Mclaren employees .

I am going to do all the tuning myself. For questions/input related to the ECU and wiring I'm working with Apexspeed in CA and Pectel directly. I agree, doing anything for the first time has inherent risks, but we've all done our homework, including scope test the unit with a rotary ignition configuration that I put together with them. If it doesn't work, I'm to blame ! The ECU itself is incredible flexible and they have a lot of experience setting it up to work with different applications. It has been used on everything from the DB9 Lemans cars (they won this year), the entire Champ car grid, offshore powerboats, motorcycles, and even a modified diesel motor with direct injection control. Right now they are working on a BMW M5 V10 setup with an ion sensing knock system.

The EGT probes for the manifold arrived this weekend:
I also had Mandeville redo the downpipe dump tube (3rd time by the third shop if anyone is counting) so it can be R&R'd without stripping the motor down to the shortblock.

Today I needed some wiring supplies so I took a little field trip to the East coast distributor of Motec.
:p
To put the content value of this cabinet into perspective, I paid over $200 for just 1of those mil-spec connectors.
This is the work area. The stations on the right are used to build harnesses. To the immediate right is a scope and test bench. The marker board on the left edge of the picture lists all the cars they have coming in. There were 2 RX8 track cars on the schedule. Toward the back and around the corner is a massive stock of just about everything listed in the Motec catalog. It's like Motec candy land. I went there for a $20 part and spent $400 :p. From top to bottom: Raychem 55 wire, DTM connectors for the traction control sensor wires, 12 position trim switch to adjust anything controlled by the ecu, Motec wastegate solenoid, and 6 Raychem glue shrink T connectors for the ignition harness.
More to come.

AWESOME!!!!
I just read throught this entire thread for the first time.... Amazing is an understatment.
I hope to do a project like this one of these days.
I would say good luck... but doesnt look like your going to need 'luck' to complete this project, only hard work.
