87 na vs. 06 solstice
Ok last summer my bosse sold me his 87 rx7, it's all stock except for the bonez cold air intake i just got (going in tomorrow or sunday).... so we were at a red light the other night just by chance and he smoked me...he said i could get a rematch anytime I wanted. So my question is what do i need to upgrade to beat him next time. keep in mind his solstice is 177hp and is perty much all fiber glass, so it weighs a lot less then my rx7. Please help. I wanna put his mid life crisses on ice it would be so funny at work.

Get a good start and shift as quickly and smoothly as possible. I always shift around 6600 RPM whn I'm getting on it. Take out stuff you don't need anyway not just for one little race. Take out all the unused speakers, amps, AAS motors, foam above gas tank, rear wiper/motor, wiper fluid tanks etc etc... Also take the advantage of having less gas in your tank. If you run with 3 gallons of gas as opposed to 16 gallons you'll be save about 70-80 pounds.

13 gallons of gas weighs about 100lbs. 
20lbs. <---> 1HP (S4 FC only, varies by car weight/power)
A lighter flywheel can equal up to ~200lbs. (400lbs.? I don't know exact value, and it varies) in 1st gear. As the gear gets higher it becomes a lot less.
Stock weight for the Solstice is 2900lbs. I don't know what all that fiberglass would save but probably no more than 150-300lbs. So looks like you need 180HP or so.
Don't just get catback. A performance cat is important. Make sure your cold air intake is really cold air: it must be sealed off from the air under the hood and open to outside air. The cold intake should yield 6-7HP.
That's a pretty blue. Take good care of it.

The Bonez kit isn't a cold air kit.
Weight reduction (ac/ps/jack/spare/random bolts/removal of sound deadening material, and so on, Bonez test pipe/COrksport
cat-back, true cai, and a SAFC with a tune. Best bang for the $1000 buck and only if you have done preventative maintence ahead of time.
I still don't think you'll beat him myself, but maybe he'll miss a shift
. Keep in mind your car is 20 years older and the engine may be pretty tired.

^ same here....nearly 5 grand invested...see sig, plus i have a Lightweight flywheel and street/strip clutch going in.
BUT i have a feeling my N/A is more responsive than most TII (i could be wrong) which makes it hella lot of fun...
I still have to do the intake side of my car and port/polishing of the intake mani's. then maybe i can break like 160whp? ha!

I still and suprised about how much mroe aerodynamic drag the solstice has over the FC... CD of .44 for the solstice vs .31 for the FC. And an aero dit knocks it down to .28 for the FC.
.44 is seriously pathetic for a newer car, especially since they should have run it through cfd analysis before they produced it.
