build a cobra engine for boost set up??

03stangGT · 03-25-2004, 07:06 AM

I'm considering buying and engine to play with... here is the idea. My buddy who does the work on my car (as well as his 11 sec cobra) has a friend with a 1996 cobra motor he is selling. he can get me the complete motor for $1k the motor has 70k miles and runs mint! Would it be a waste of time for me to pick up that motor, install manley forged rods/pistons, and bearing kit, with low comp pistons? I'd like to build the motor for a blower or turbo application. This would all be going in a 2003 GT. I would like to keep my GT motor stock and keep it as a back up. I wanted to build a 4v because of a few things... I like a motor that rev's! and the cobra motor does compaired to my GT. Also it seems as though you get more HP from boost as compaired to a GT. Soo would this be a total waste of my time? Is there a better way to do this? keep in mind I'm not going to touch my GT motor, and I want to build a 4v, and not spend $5k. ANY opinions would be great....thanks in advance!

ps...the stock crank in the cobras are forged arent they? wouldnt wanna have to spend another $1k on that

That sounds like a good deal. How much power do you plan on making? That will determine if internal mods are needed.

Well as far as power, my wish has alllwaayyyss been to have a turbo set up. but if I get impatient in my saving efforts I will most likely go with a novi s/c. because it is about 2k cheaper! and I would still be happy with that! I would like to be atleasttttt close if not a little more than 400hp to the wheels, because I would like to keep is as driveable as possible. The whole idea of me installing the forged rods/pistons, and having the block bored slightly is to start over with a fresh engine (or close to it). and also SHOULD be totally reliable that way. because I love this car and want to be able to drive it as often as I choose. I've got a question though...if this does not come with all the wireing from the cobra, where could I get all that? how much would it run me? thanks guys...also can you see any problems I may encounter?

You can pick up the wiring harness on ebay fairly cheap. I will be using a TEC3 engine managment system from Elecrotmotive for my 4v. It replaces all the factroy electrinics and allows you to run a supercharger without an FMU or a burned chip and will increase drivablilty and overall performance. Its only a few hundred more then a stock EEC and wiring with a burned chip and dyno tuning.
