Warlock Camaro
Thought I would introduce my 71 Camaro.
Not your ordinary 2gen Camaro this one will be powered by a 2.0L 4G63 four cylinder. It will be running one of my stratified lean-burn prechambers. The transmission will be a 4L80E with a lock up converter.
This setup will also be a dual-purpose FE/HP car. Goals are for it to run low 8's @ 170+mph, and to be able to get 45+mpg Freeway.
Mods:
Weight reduction down to 2800lbs with driver.
Improve Cd to .27 or better.
Lean burn with A/F at 30:1 freeway and I don't have to have any emissions other than a PCV valve
Fuel: pump92 for the street, GEM 47 for the track and waste solvent when I'm broke.
My wife and I will be doing a YouTube on the build starting next month.

Interesting read on Motor Trend back in 2007.
Car Aerodynamics - A2 Wind Tunnel - Wind Camp Tech Theory
https://www.motortrend.com/how-to/car-aerodynamics/
In the picture part of the write up.
https://www.motortrend.com/how-to/ca...f-f637f485b165
Just adding the grill block and front air dam the Cd went from 0.497 to 0.337.
Amazing!!! Then adding the rear spoiler that mimics the HRM SPL Camaro dropped it to 0.292.
https://www.motortrend.com/how-to/ca...f-32e73ab5a2b2
The HRM SPL Camaro tested at 0.201 Cd.
There is hope for my Camaro after all.

This is a pic of my front mount air to air inter-cooler. This is the last cooler before the intake there is also an air to water cooler that cools the first stage.
I am working on building the hot air system today that will be used for FE. Going to use the by-pass valve to by-pass both intercooler's that will be able to have air temps around 250*F.

So, did you have a spare engine and just wanted to try it on something else? How do you expect it to fare on something with a noticeably different drivetrain layout?

Thank you for the interest.
Yes, this is a different engine (one of three) with higher compression. I wanted to try a higher compression engine 10:1 compared to the Talon's 8:1. The head is different also, made some changes to the fuel delivery in the intake port runners. The Camaro will have a removable front end that my wife and I can easily remove by ourselves. This will make it easy to test cams single valve swirl low lift lifters etc.
I think the FE will be way better than the Talon just based on it having a
RWD vs AWD. The aero should also be a lot better. The gearing will be better for FE too. After going through my data logs I think the Camaro should be able to get around 70MPG Freeway with the FE Cams?
Here is a pic of the Intake and a few different HP turbo's. This intake has a dual rail so I can run two different sets of injectors. I want to run a small set 390cc/min on the primary's so I can run higher rail pressure for better atomization to improve FE.

Seems quite promising to say the least. And it does seem to be an easier testbed to keep looking for improvements on the long run, as it seems like there are much more aftermarket rear-end ratio options than what could be expected regarding the Mitsubishi transaxle and rear differential.
On a sidenote, what has led you to fit a Mitsubishi engine to a Camaro? Was it just based on your previous experience with that engine and willing to try it on another testbed or any other motivation? Well, maybe some info about the bolting pattern would be of interest to the off-road folks who often adapt some "unexpected" engine and transmission setups (which seems to be the case of a Mitsubishi engine backed by a GM transmission) to their rigs.
