creating a 964 turbo from a NA 964...
So I am looking forward to a new project that sounds like it should provide a fantastic result.
I am thinking of turbocharging my 964 which has a newly rebuilt stock 3.6 liter engine. The engine is stock except for ARP rod bolts and AASCO titanium retainers. To create a 3.6 turbocharged engine, what parts do I need? Pistons I assume are different, connecting rods, heads, intake, exhaust - and how about the motronic electronics? Is it just easier to find a used 3.6 Turbo engine? Do these come up for sale often? And for how much? Thanks

You'd be better off finding a Turbo......

Well, I don't want a 964 turbo chassis... I just want the engine

Hey Garrett,
You might consider supercharging. TPC makes a bolt on kit.

stay away from superchargers...
your 3.6 NA Motor is a much better base to start from for a turbo upgrade then the CIS equipped factory turbo 3.3/3.6 motors. You already have twin plugged heads with excellent flow, very nice intake manifold, motronics, etc... You have two choices, go with a bolt on low preassure kit and lave the internals alone or take ot back apart again to install lower compression pistons and beef up your rod bolts. Either way you will need new exhaust work, intercooler and it's plumbing, proper fuel and reprogramming of your motoronic DME. Todd over @ Protomotive does alot of these types of conversions, I would also talk to Chris Carroll @ Turbo Kraft. Do your research and decide what you want so you don't waste money. |

Hey Guys, thanks for the info. Supercharging isn't what I want for this particular car (a track car), since superchargers are great down low but lose it up high, whereas turbo just keeps going!!! Wooo hoo!!!
I'll have to check over with Todd and Chris, but I am sure the kit prices are really expensive - getting the used parts is fine with me... that's why I wanted to put together the parts to see what's necessary. Is reprogramming of the DME as simple as a chip reinstallation? Seems like it should be as long as the boost is controlled mechanically... |
