Don't worry about heads/cam if you're trying to beat a 14 second GTP.

Get 3.73's and long tubes.

For his KR problem, has your bro ziptied all of this dipsticks or anything else that can cause false KR to something stable? I know the tranny dipstick kinda shakes and the oil dipstick can vibrate on the exhaust manifold. Another thing about the 97's (my GTP was a '97) was that the ABS system pulls timing. So at the track, I would pull both ABS fuses in the glove box out. The brakes still work, but disable ABS entirely. Yet another thing would be to put in a little 5ohm resistor into the IAT sensor. It will fool the computer into thinking it's 5*(depending on where you live, this might not matter. Here in AZ it helped me out.) and give you more fuel to help fight detonation. And last but not least, if he hasn't done it, swap to a 180 drilled t-stat or a 160* stat, flush out the radiator put in water and 2 bottles of water wetter. All these things got me down from 8* KR to ZERO KR in 120* AZ summer temps.

I'm not big on stall knowledge, but 3K is the minimum stall you should look into. And 3.73s would be a great step up from your 2.73s. You should easily drop .5 in the 1/4 just by adding gears.
Yeah he also put in like a gallon n a half of racing 110 n that took care of it al though it fu$% his O2 but o well so he knos the kr is real the data logger also confirmed that. ive never heard of pullin the abs but ill say simtin to him i think he found a deal on sum SLP headers w/ a down pip includued so i think thats the rout he is gona take on that

honestly.. do headers, then gears,then a stall. and have it tuned. im not sure if this is out of your budget but of you do those mods he wont be able to touch you.

if your on a tighter budget.. id say go with a tune and stickier tires if traction is a problem. also dont rule out weight reduction its free afterall, take out smog, ac, front sway bar... that will see an easy 75lbs off the front end and itll make a nice difference.

try 3.73 and a 3200 stall IMO (some say 3.73 with a 2800 stall i felt it was to low.)

At a minimum...3.73s. When I switch from 2.73s to 3.73s...felt an instant "umph" from a roll that wasn't there before. I did upgrade the converter just a tad...2200 or so.

Then the rest is good stuff..higher stall, headers, etc.

I like this advice the best, but still wouldn't do that steep of a gear if the engine is stock. I'd be more prone to 3.42's.
