2003 Cobra mods

Nov 30, 2004 10 Replies

I'm looking for suggestions on where to start with increasing performance from my '03 Cobra convert. (new purchase used car). Some cost effective ideas I've seen are:



upper pulleys Mac exhaust cold air kit performance chip and tune throtle body NOS


-Pat


A smaller (2.8") supercharger pulley and a Hypertech programmer seems to be a pretty good bang for the buck.

Pulley info and how it installs: $75-80

puller costs more than the pulley! Hypertech programmer: $350

A couple things about the programmer...it's not for the automatic Cobra and has it's best results from a basically stock setup..I've heard that larger throttle body and MAF might not produce better numbers with the programmer. Do your homework...talk to the manufacturers.

Hava goodun.

Automatic Cobra? I don't think there is such a thing is there?

I was just going by what I saw on the site...It specified manual only..so I did the unthinkable and assumed there might be another option. Live and learn.

Well that's one thing less to be concerned about.

Automatic????

No, this is a 6-speed man. Where did "automatic" come from?

Thinking of following:

CAI X-Pipe w/cat back throttle body w/plennun

3.0 upper, 4# lower, idler pulleys Diablesport chip and tune

-Pat

I'll do that...thanks for the enlightenment...oh wait, someone already pointed that out and I already acquiesced to that fact.

"Intake Plenum" I believe.

-- A happy kid behind the wheel of a 98 Mustang GT Cold air intake FRPP 3.73 gears Steeda Tri-Ax Shifter Full Boar turbo mufflers Hi-speed fan switch

255/60R-15 rear tires Subframe connectors

Only those so modified to be. None ever came from the factory with a slushbox. I have heard of people putting automatics behind them though - probably *much* easier in the '93-95 cars before the EEC-V took hold...

Not sure why you'd want one, but to each their own.

heres my .02 and in order:

- catback

- air intake

- weld in subframes (vert)

- pulley/tune (or if youve got the $$, twin screw blower upgrade)

- etc, etc...

you will def need some tires for the power if you like to drop the clutch.

i have owned an 03 and an 04, and gained almost 60 std hp from airbox and catback alone on the 03 (havent dynoed the 04)
