CMonakar Mandeville 20B GT42R Project
Things are moving along. This weekend I'm focused solely on the car -I decided not to go out tonight so I can get up early tomorrow and make some meaningful progress before lunch time
.
The electrical is 90% done -I have to add a few connectors that aren't essential to getting it started and double check all the harness-to-harness connections to make sure no wires got pinned incorrectly. I created a new alternator harness so I could move a few stock items over to it that were eliminated when I replaced the stock 2 rotor engine harness. Note the new alternator connector and sealed heat shrink on the stock connectors.

Here is a shot of the engine bay from last weekend:

I will try to post new photos tomorrow night.

Good looking progress! Couple things...
That bay is screaming for a blingin' PS pulley...and is your tensioner pulley backwards? MAP sensors like to have the nipple facing down and above the sensing point.
looks like it's coming together nicely.

WE HAVE IGNITION

I started the car for the first time yesterday. The sound is mind blowing. It has a very deep tone, but revs like a sport bike thanks to the light weight clutch. It is like a 2 rotor single turbo turned up to 11.5. The engine is loud, the turbo is loud, and even the fuel circulating through the lines is loud (It can clearly be heard at the front of the car with the engine off). I am very impressed by the Pectel ECU so far. Being able to log every sensor connected to the motor with alarms takes the pressure off having to keep track of everything in real time.
I will try to post a video this weekend.
I still have a lot of work to do before it is road worthy. dubulup -you're right about the map sensor. A 20-30%+ angle is recommended to avoid the accumulation of condensation. The current zip tie mount is temporary. Same goes for the Power steering/AC -just a place holder to route the fuel, oil, and electrical stuff around.
More to come!

I was there when the beast was running......chris isn't kidding about the noise. You can hear the fuel rushing in the engine bay, it's pretty nuts. Chris, when you're ready to do another, my FC vert is available
Thanks David. I could same the same thing about your car. Your dyno videos are in my permanent collection.
Wanklin, no major leaks. There is a small coolant leak from a sensor in the water pump housing that was installed without a crush washer (on order), and I have an exhaust leak that is an easy fix. No major wiring issues, although I had to redo a thing or two over the last few months

I made some progress this weekend. I had to pull the turbo system off to replace an exhaust gasket, so I lost most of Saturday to that. Today I got everything back together, installed the cooling fan relay setup, made a new throttle stop for the throttle body (removed a lot of the stock linkage), and 'attempted' to bleed the clutch.
Here are 2 short videos of it starting and at idle. I still have to do a lot of tuning work (note the AFRs and the backfire), but things are progressing.

'Attempting' to bleed the clutch is loads of fun. I think my leg muscles are growing as a result of the workout. "Come over, it'll be done in 20 minutes" my ***
Congrats on firing it up! The car sounds great.
I've been following this thread since it started and I'm glad to see it's just about complete. Hopefully, one day I can tackle something like this myself. It seems there has been much attention to detail throughout the build and I enjoying seeing great work like this. It's been very entertaining to read about and I wish you much luck with the car.
Enjoy every last bit of it!

Thanks for the positive feedback guys.
LOL. You should know not to trust my time estimates given that the motor swap has taken 12 times longer than expected. Thanks again for helping with the clutch.
Thanks Gordon. I think you hit it on the head with that line!
I can't say enough good things about the ECU. The best part about it is that it is completely transparent; you can see exactly what it is doing in real time by watching the status column on the right hand side of the screen while the engine is running. The column provides a macro view of the engine in the general mapping menu and drills down depending on what submenu is open, while still keeping basic things like RPM, TPS, Temps in the picture.
The timing logic menu it lists more information than you would ever want to know about the operation of the crank sensor. With the 60-2 trigger wheel it is a very precise system. One of the engineers sent me nearly a page of information explaining what the ECU does during just the cranking process.
There is an error prompt and log for every sensor connected to the ECU, which can be adjusted and ou can set it up to take a number of steps to protect the engine if an error comes up. The other neat thing is that in addition to the data log, which can be setup to run basically non stop, it keeps track of a bunch of data points over the life of the engine (min, max, and duration for things like RPM, water temp, boost ect).
But you thought it all out and were right in your choices (except the essential decision or choice to do the damn thing.
