Sounds to me like something is a little off. Check your pipes, make sure all clamps are tight, get a gauge if you don't already haver one to moniter boost. What type of gas are you running, 91or 93. How many miles on your car? Is your clutch slipping, that could cause alot of problems. Stock you should be in the 13's. No offense but that is the worst time I have ever seen. Hopefully we can help you figure this out. What do other Evo's in your area run?

By the way a 2.1 60 is not so good. You cut a 1.8 and you will knock roughly 6 tenths off your quarter. Every tenth down low is about 2/10's up top. Also alot of guys lose a good bit of time in the 1-2 shift as that is the hardest shift to do fast when you race. Pretty sure I could drive your car to around a 14.0-14.2 but still there seems to be something up

- i am running 92 octane
- 3500 miles
- clutch seems to hold , i get good 60 foot times (less than 2 seconds) so i dont think the clutch would give out when i am driving the rest of the distance
- i have seen other evos in my area run in the low 14s to high 13s stock @ 96 mph. this track is a little slow compared to the mainland
thanks for any help

I would strongly suggest taking your car to a DD dyno and getting some good information before taking any action to modify your car. Many of these slower EVOs suffer from some kind of knock or something that the ECU "thinks" is knock. In these cars, the ECU pulls timing like crazy to "protect" the engine and the car will never be really fast until this situation is corrected.
When you take your car to the dyno or at least find a way to do some good data logging, you'll see what the engine is doing. Only then can you begin to take corrective action. Likely as not, you'll have to either spend lots of bucks chasing down and correcting the issue or spending more bucks for nothing by modifying the car to try to get more power.
IMHO, based on expensive "education", I'd suggest you run like the wind form any tuner who promises to modify your car into high performance before determinig and correcting whatever is causing the low performance now. I'd particularly be wary of any mail order "miracle cure". Also, bolt-ons will be a waste of money too since they cannot correct the timing pull issue. You can also consider taking the car to the dealer after you have proof of unusual performance such as timing pulled and request they either take the car back or correct it. You sure as hell wont be able to do that if you modify the car first.

.664 - reaction
1.990 - 60 foot
9.142 - 1/8 mile et
75.16 - 1/8 mile time
14.633 - 1/4 et
89.46 - 1/4 mph
its like my 3 and especially 4th gear dont have the power to reach the 95 plus mph? is their some kind of fuel cut out at this speed? some restrictor? something wrong with the ecu to die at higher mph? something is not right with my top mph speed- cant figure why i am not reaching at least 95mph!

what would you think if i replaced the timing belt or some adjustable cam gears?

My mistake for not paying attention to where you are from, Hawaii has got to be up there with the slowest drag strips in the country. Not just EVOs, but times there are just pathetic. You point this out when you said all other EVOs (stock) were running high 13s to low 14s, and yeah that's about average for island. the second thing is your driving, it needs to improve, the way you launch and shift need to improve. Better driving will not only improve your times but also your trap speed. Combine slow track, with inexperience driving and what do you get, a 14.6-14.8 EVO...
