DISCLAIMER: BEFORE the comments even start, this is a THOROUGHLY researched project. The 4.9L is more than capable of handling the amount of boost that I will be using during this project. The 4.9L engine HAS been successfully turbocharged before, so this is not stepping into unknown territory. I have already taken care of fuel management considerations and don't need any outside input / concerns / complaints. Thank you for your support
Initially for my turbo project, I was going to use a turbocharger from a GM 6.5L Diesel engine, since it spooled up slowly enough to not increase the already massive low end torque of the 4.9L engine. However, after careful consideration, I've decided to go with a smaller turbo and kick up the torque a notch more. I will be using a Mitsubishi TEO4H Turbocharger (shown above), which I will be limiting to a maximum of 5-7 lbs of boost
This particular unit has received extensive internal polishing by a friend at a local performance shop, whom deals with turbochargers on a daily basis (Thanks Lee !!). This should eliminate some of the exhaust restrictions found in the TEO4H Turbocharger
The brass tees for the oil lines to the turbo have already been installed. The Cadillac 4.9L engine already runs engine oil to an external cooler, so plumbing the turbocharger into the system will be a piece of cake
At $10.99 a can, this special ceramic based paint manufactured especially for turbochargers does the trick
A little electrical tape protects the internals during the paint process
For anyone wondering where the hell to stuff a turbo in an already cramped engine compartment, take away the OEM Cadillac Air Filter Box and you have plenty of room
Any questions !?!?
Closer inspection reveals a change in the turbocharger since the last photos were taken. Notice it yet ?
I have "re-clocked" the turbo housing to match the location of where I want the outlet to be placed
Re-clocking the turbo was done by removing the band clamp and using a hacksaw to remove the "key" between the the turbo halves
In order to ensure accurate timing under boost conditions, the MSD 6A Ignition Controlller will be used
To Retard the timing under boost, the MSD 8762 Boost Timing Master will be used. This particular version works ONLY with MSD Ignition Controllers
This is my custom wiring diagram for integrating the MSD Controller and Ignition Retard Box into the Cadillac's HEI Ignition System.
SECOND DISCLAIMER: Although MSD does indeed offer the MSD 6 BTM, I have my OWN reasons for running a seperate MSD 6 Controller and MSD Ignition Retard Box. I am WELL aware that the 6 BTM is available.
