BackMy Car PicsKIA

When I first got my car I thought it was as 350 4-barrel TBI, since then I learned that the guy I bought it from was not telling the truth about the engine. The engine is a 305 2-barrel TBI engine. It is rated at 170HP at 4000rpms and 255FT/LBS at 2400rpms. The car easily smoked it's tires dead stock but really had very little pull for a V-8, so I decided to mod it.
The first mods I did were a flowmaster muffler, hypertech chip and K&N air filter, which seem to be VERY typical mods. The results were better throttle response, and the ability to rev to 4500rpms. I ran it at the track at a scorching (being sarcastic) 16.2 at 84mph. I was disappointed in it's performance.
The next mods I did were a shift kit and Nitrous kit from NOS.I told the tranny shop to install the stage 2 version, but they installed the stage 1 instead. It still made a noticeable difference in the car's performance. The car would not catch a 2nd very often but once in a while it did. With the Nitrous it would probably catch a second. I say probably because even from 30mph rolls as soon as I would hit the button the tire just lit up.
It was about a year before I did my next mod, which was a 3.42 ring and pinion from Richmond and a SLP posi unit. This made a big difference in the feel of my car, now the car would catch at 10mph roll blast of the NOS kit and not light up in smoke like before. I also got a harwood cowl induction hood a little while later but only because of an accident with my original making it unusable. The car ran a 14.4 at 97.5mph at the track with a bad O2 sensor, I feel the car had very low 14 second possibly even a 13.99 capability since of the Nitrous it was only running high 16's. After I changed the O2 sensor the car felt like new.
It was over a year before I did my next mod which was a pair of headers and 3" cat and cat-back. This was the most PITA mod but well worth it. The exhaust was now much more aggressive than just the muffler. I recommend this mod even for just the sound it's worth it. I gained a little low end and a good amount of midrange torque. I G-teched the car after and it ran 0-60 in 7.2 seconds and 1/4 mile in high 15's (at a corrected for G-Tech) 86mph. *90mph indicated.
After the exhaust was flowing good I decided to free up the intake by performing the Ultimate TBI mods in the Thirdgen.org tech section. I also did the resister mod, open air element and pulley at the same time. This made a really big difference in midrange and top end. The car now ran 0-60 in 6.7 seconds and 15.3's at 90mph. *93-94mph indicated. The car now felt very strong.
The next mod I did was a Holley Projection intake manifold and 670cfm TBI unit from Holley. This made very little difference and the car got worse mileage, so I ordered a custom chip from Ed Wright at fast chips. After the chip the car got it's mileage back but didn't perform much better, althoughit did have more topend beause of the intake and TBI unit. It now went 0-60 in 6.47 seconds (best time) and ran a G-tech 1/4 mile of 15.05's at 91mph. *95mph indicated.

I decided to go for 14's N/A with my stock cammed, stock compresion, stock stall converter, full weight (except for the fiberglass hood) 305-2V. I swapped out the cylinder heads for a set of World Products Torquer 305 cylinder heads. This wasn't too hard but took a while to do. After I put it together the car wouldn't run worth a ****. I accidently had adjusted the valve while the key I got from Autozone to check engine codes was still in. I had it towed to a local shop and they charged over $200. It runs about as good as it used to in winter but this is in summer heat. So, as soon as winter comes around I expect low 6's 0-60mph and high 14's at 92-93mph. Although I have a 204-214, .420 .442, 112LSA grind flat tappet cam sitting on my shelf just itching to go in as soon as I acquire another means of transportation to be able to afford the downtime, hehe. The stock cam sucks *** at 179-194, well under .400 lift along with a 115' LSA. As soon as I get that cam in and get my chip reburned, it's time to start messing with some automatic LT-1's Z28's and auto 4.6GT's.

*Indicates the mph actually registered on the G-tech Pro itself. Due to this device giving an instant mph VS. an average mph, like at the track, it is anywhere from 2-4mph higher. The ET is usually with half a tenth and 0-60 is as acurate as you can get.
