What's the difference between the 97 and 98 2valve

[Carlos I Munoz Montoya]

I want to find out why the 98 2 valve makes a bit more power than the 97 2 valve. Do they have different computer/tune, or intake system or ??. Let me know please.

I can promise you both racing side by side, neither would out do the other.

Ight. I'm just trying to figure out what I can swap out from the 98 to my 97 to get the extra bit of hp after all the mods ive done.

The specs I saw showed only 10 hp (215 to 225) hp difference and same 285 ft. lbs torque. What I saw on Wikipedia was that the slight HP increase was due to updated PCM calibration and a modified fuel system. Probably not worth the hassle.

98 has a bastardized return style fuel system. Fuel regulator is built into the fuel rail. It is a one off year. The rest is programming. Get a tune for your car and do a pi intake swap. It is the best gain for the buck.

You could gain 10+ horsepower easily by doing PI cam and intake swap.

Great looking car by the way

Yea, get a PI intake and do a tune, and gears. That's where you'll see your biggest "Bang for buck" stuff

I have 4.10 gears install kit from ford performance but every shop around my town in Napa, CA are charging me 900$ for the install.

Seems a bit steep

Look for a 4x4 shop. They'll probably be cheaper and they usually do a ton of gear swaps.

I'll look around for 4x4 shop see if theres one close by

Do you have a recommendation for the tune? Canned tune or Dyno? I just did the swap and can attest it's a very nice power add.

a dyno tune will almost always be better then canned. There are some great tuners out there that can do it right via email, and there are also some crappy tuners on dynos but in most cases its hard to argue that having real time data while doing it(assuming the tuner knows what they are doing) isn't better. Do some searches and see if your local tuners have good/bad reps. If they do good work I would pay the premium for the dyno. If there are no good tuners close then I could fall back on a good email tune.

I used to work for Teksid Aluminum back in the '90's at the Dickson, TN foundry. Only difference was the exhaust ports were tweaked slightly as well as the factory tune. I did some work with CAD and the Dimensional Lab. The mathematical layouts were different on the '98 casting. No real biggie.........

My 98 gt with an automatic transmission was week
I added a automatic shift kit street or strip and added 3.73 gear , next was the cats removed and put in a off road x pipe , that helped out quit a bit. this is for
only cars with auto trans.
