First mods for my 97 Cobra

Got a 97 a month back. Wondering what some of my first mods should be. It's all stock now. I know I want to put 4.10s on it. What else should I do. Not wanting to do anything to expensive right now. Keeping it under 1500$ all together for now.

When I get the gears, what is the best route to fix the speedometer error. So I can't get the correct mph

Tplanck,

Here's a link, just call and they'll hook you up. It's about a 20 min job with a manual transmission. Good luck!

This goes back a number of years and different configurations on my 97 Cobra and if I remember right I did the exhaust system. Remember that you have 4 cats, 2 on each side and even deleting two can help alot. At the time there were very few people making equal length headers so I went with the FRPP shorty headers, Bassani cats and x pipe and left the stock mufflers. On the dyno the shorty headers made almost no difference until you got above 5500rpm showing the factory cast headers weren't all that bad.
I did a lot to the rear suspension, Steeda lower control arms, and Maximum Motorsports relocation brackets and panhard bar. I also did Eibach Sportlines and 17" Cobra R OE wheels with Comp TA's.
I took the 3.23's out and put in 3.73's...........unless you are planning to put a supercharger/blower on the motor or change the trans to a HD Tremec 6 speed I would only recommend going with 3.73's. The motor just doesn't have enough HP/TQ stock to pull much speed above 120mph in 5th............found this out the hard way while racing the Silver States Classic.
$1500 is a pretty slim budget to do very much.
What are your plans for the car....DD....Weekend Toy.....Drag Race.....Track???
Only have a few pictures of the 97 in my pictures as that was over 18 years ago.
The car was I think around 265HP ATRW stock and when I finished the N/A part is almost 310HP ATRW..............

It is my DD. I'm only 19 so I don't have a great amount of extra cash to dump into right now. I have read that a lot of people that had put in 3.73s wished that they would have went with the 4.10s. And the people with 4.10s were happy with them and glad they didn't put in 3.73s

Do the math and see what kind of RPM you would be running at 70/75mph with 3.73's and 4.10's. With my 3.73's I could pull down 26mph at 70mph....if gas mileage is of no concern go with 4.10's.........gears don't make a car faster although it feels like it is.
I'd like to see some pictures of the car and how many miles it has on it before suggesting a direction although it's your car and your money..........what direction do you want to head in.
I think the very first mod I did was to lower it and put on the original OE Cobra R wheels...17x9" with 24mm offset for the front and 17x9 with 35mm offset for the rear....these would clear the 13" brakes......back then we didn't have as many choices as you do now. I know I was waiting for the aftermarket to come out with 17x10" rear wheels.............never got any though.

Also the drivers side seat started to wear and it was also replaced under warranty. After putting the Kenny Bell supercharger and trying to get 12lbs boost I broke the motor, then built one with better rods and pistons.....both are weak areas of this motor if you pound on them hard enough and with 100k+ on the odometer I would go out and start racing with it.............looks like a nice car.
I would do gears...........it's your choice........and depending on how much you have left I'd work on the exhaust and getting rid the four cats and going with a system that only has two. Or you could keep the 3.23's and get a nice set of wheels and tires and lower the car..............your choice.

Thanks for the advice. I'm don't mind the rims on it now, probably just going to do performance mods on it little by little. It's a fun little car to cruise in with the top down. Thanks

For $1500? 4.10s, mid pipe/catback and a tuner. Not really too much power wise that needs to get done to a 4V besides the minor bolt ons. Even the stock manifolds really don't need to be replaced unless you don't have anything else to do and are keeping it NA.

You should definitely do a full tune up on it first obviously. 4V Cobras can have issues with the secondary intake ports and IMRCs getting clogged up as well. A seafoaming can't hurt in this regard.

When you get some more money, work on the suspenson/chassis. Stock 04-down suspension is... well it sucks. But the good news is the aftermarket is here for you.

Where exactly should I insert the sea foam? I know you can put it in the gas tank, but I think you can put it somewhere else for issues like that?

Take my word for it, as I owned a 97 Cobra...........3.73's are plenty deep enough for the street. You will break the tires loose in first and second gear just about perfectly with this gearset, and still pull well after that without running crazy revs on the highway.
Secondly --- you will LOVE a shift kit, and it makes shifting almost like racking a gun. I am trying to remember the brand I had in my Cobra, but am not coming up with it. The shifter was spring loaded for the 2nd to 3rd shift, so all you had to do was go forward, and there was no danger of missing that shift.
The shift knob was as solid as a rock, and did not move at all when it was in gear. It absolutely spoiled me for any other manual I've ever driven.

It's been some time since I owned it but I believe it has an H pipe which is stock. Each side has 2 catalytic converters. I put on a Bassani header back system which only had 1 catalytic converter per side.
We did many dyno pulls with the car in various stages of mods and the the X and H pipe made no more HP....changing to the Bassani with only 1 catalytic converter did make a few more HP and the X pipe was just louder....I don't care for loud exhaust.
As was mentioned earlier, putting headers on the Cobra is just a waste of good money as there is no HP gain over stock until you get above 5000rpm.

Yeah I didn't plan on putting headers on. They are pricey and it doesn't seem like a good bang for my buck right now.

You guys have any thoughts on a CAI for these cars. They are all pretty pricey 250$ and up on AM. Are they even worth picking up?

That's reasonable for that mod. The cai for the newer cars are between 350-450. I mean you could always get your cobra the absolute best and buy a $80 one of eBay. In all honestly of your going to put stuff on your car especially something as important as a filter spend the money and get something good don't cheap out. You can also looked for used parts.

They are really a looks only mod. I'd spend the money elsewhere.

Yeah I think they are the most over rate mod. The stock one can't be that bad.

It has a stock "H" pipe.
It has SIX catalytic converters.
MODS:
-MGW short throw shifter
-4:10 or higher ratio gears
-Air/Oil separator for PCV system is a MUST.
-Exhaust system with stock headers or Bassani mid length headers, swap out 6 cats for 2 hi-flow cats, ect..
-Properly chosen lowering springs and accessories.
*~Once you have the bigger items ironed out, you can address the cooling needs and other odds and ends that need attention after 20 years,

Never have seen a 96/97 or 98 Cobra with "6" catalytic converters.........my 97 came from the factory with 2 per side.........that equals 4 last time I counted....unless you are talking about the resonators......
