01 Cobra vs 03/04 differences

[SCtobe]

I've got a chance to pick up an absolutely mint 01 Cobra... and I intend on putting a KB on it.

But before I proceed i'm looking to find out the differences aside from the stock Eaton blower between the 01 Cobra / Terminators... Are the stock internals the same? What are the 01 rated for? What setup's are you guys running and what power are you making?:read:

feed back is appreciated!!!

(Also this car is a Teksid block)

Besides the obvious body differences I believe the lower end of a terminator is quite a bit different, crank, rods, pistons, etc..... I think the 01 Cobra is the same as an 03/04 Mach 1.

 

[SCtobe]

do you know if the rods / pistons are forged?

99-01 cobras DO NOT have forged rods or pistons while the 03/04 Cobras do. 01 cobras have a "weaker" IRS with 28 spline diff while 03/04's have a 31 spline. 03/04 Machs share the SAME heads and cams as 03/04 Cobras. All the Machs came with a solid axle. There are MANY more differences to list.

99 Cobras have 28 Splines. the 2001 DID get 31 spline axles

OP, please read the stickies and all at the top.

oops i stand corrected.

The car im looking @ has 31 spile...and correct me if i'm wrong but if the axles are 31 spline so is the diff..... lol

 

[olgreydog7]

yes but the 01's have a 28 spline diff.

That would be a square peg in a round hole dude oke:

Yes, you are correct. If this is going to be a driver, get the 03. The car will be down alot to rebuild the shortblock and then put on the blower. But, if you have more time than money, get the 01. It will be cheaper to build than to buy an 03. The 03 also has a T-56 6 speed with an aluminum flywheel while the 01 has a 3650 5 speed and steel flywheel. Plus, the IRS has a beefier crossmember under the diff on the 03. The 03 has Bilstein shocks/struts. Those are the main mechanical differences.

i honestly think the exterior quality of the 01s is better than the terminators... my 01s paint was very smooth hardly any texture... and i know it was never wet sanded or repainted, other than the parts i put on it... but my 04 and many others i have seen have a ton of orange peel on them. Its not a big deal just what i noticed

 

[01trublue cobra]

01 is 31 Spline. OP please use the search button this has been discussed a million times.

 

[SCtobe]

sorry didn't realize until a minute ago what OP meant (original poster) I assume and had no idea wtf a sticky was lol. Tons of info in there though I appreciate it.

 

[01SVTSnake]

yes but the 01's have a 28 spline diff.

How does a 28 spline differential house a 31 spline axle :dw:

 

[SCtobe]

lol!! it doesn't

Quality Control was at an elevated level for the 01 model year Cobra do to some mistakes on the 99. I notice the same with the paint on my silver 01. Super smooth hardly any orange peel and 130,000miles on it.
