13's for 2500.00

[daveyboy]

I got to thinking the other day about this up coming racing season and the budjet that I have and came up with this: A 13 second pass for 2500 bucks. The subject for this exsperment is my 05 Mazda 3 with a 2.0. The car is very close to stock. Only mods are a customized air box, Grounded Throttle body and rear "dog bone" Mount.

I have a Nitrous kit already sitting in the garage Waiting to be installed. so I plan on using that.
Other plans to get me there:
Drag radials and wheels
Assorted Nitrous installation assesories
Header
Custom built exhaust(have welder and know how to use it)
Lentech Valve body and some syntetic transmission fluid (for reliability)
Wide band O2
Piggy back ecu
Remove AC belt, but leave compressor
Possible weight reduction, although i would like to keep the car looking good
Possible other mods involve porting the throttle body and thinning the shaft mainly for throttle response, but with out some sort of fuel management I am not sure if that will work
Issues that I will have
There is no tune available for the car yet, with none being planned as far as I know. So in order to adust A/F I would have to get a piggy back controller.
If everything goes according to plan I should have this accomplished by the end of the racing season this year. I will be heading to the strip in april to get a base line to see what I have to work with.

So now all I need is your input. Let me know what you think

No experience with the Mazda 3 but have you thought of any head work (i.e. port and polish, port matching, valve work, etc). You might need more than a piggy back to extract all the power that the motor has to offer.

 

[daveyboy]

I have Actually and will be using that as a back up. I have a 2.3 L head off of a focus I will use if I can. still researching it though.
I really dont think I have vvt. but dont know what to look for Solenoid ect any body know, or have a helpful pic?

What do you mean more than a piggy back

1. Learn to weld
2. Learn to weld
3. Build turbo manifold
4. Apply boost
5. Find a friend with a dyno
6. Tune tune tune (AEM FIC is pretty damn good for $400)
7. Build wheelie bars to keep front end down
8. Buy used drag slicks off someone at the track
9. Run 13s
10. Buy new clutch
11. Buy new axles

Nice list! How ever... Scratch 1 and 2 off the list already. Dont have to worry bout 10 and 11, cause I have an automatic. Well 10 any way. Not gonna give in and go turbo just yet. Gonna stick with my nitrous plan. I do have a turbo in my garage so if it comes down to it I might. But I also have a head that I am porting and that will go on before the turbo. Oh and 7 not happening. at the most I would put air bags in the rear coils to keep it from squating.
I have been looking into the AEM FIC and It looks pretty good. I have also heard (dont remember where) that they dont work with the mazda 3's cause they cant interpret the cam and/or crank signals. So I am still researching my FIC options. Thanks for your input (drinks)

Oh good- if you have fabrication skills already, you can cut about 1/2 the cost out of a turbo setup by bulding all your own support hardware. Since you have an automatic, I don't know how much the transmission will take- but you might want to look at weight reduction as your primary speed adder since you don't want to boost just yet.

 

[daveyboy]

probably have to take a couple seats out just to make the time(need to vacumn some crayons up anyways) but I am going to try with out it first. I am thinking that nitrous is my primary speed adder, should work just fine. Plan on upgrading the transmission with a lentech valve body, transmission cooler and some synthetic fluid. I think I should be alright.

 

[phunky.buddha]

What kind/brand of nitrous kit is it? Just make sure you have enough fueling to back it up. If you're worried about driveline shock, maybe you could set it up so the nitrous feeds in gradually as the revs go up? Or the torque converter could just soak it up...

Weight reduction and juice is probably enough to hit 13.99. Just remember that 60 pounds is about equivalent to 10 horsepower.

 

[daveyboy]

It is an NOS cheater system. Good to 250 hp on a V-8, gonna use a "edelbrock E2 nozzle and get some jets for it. I talked to NOS already and they told me that jetting sizes wont change even with the bigger solenoids. so I am good there. I have thought about a progressive controler but I am not 100 percent sure how I want to control it. One of the FIC units that I am looking into it has a built in nitrous contoller

 

[phunky.buddha]

Oh cool. Well, sounds like you have everything tied down already! Can't wait to see pics and timeslips.

 

[daveyboy]

Looks like I am abondoning this project as I have traded the car in. Had a few issues with it that I didnt want to deal with. Its all good got me an 06 mustang GT.

 

[SoCalMP5]

Bummer! This would have been interesting. Are you gonna play with the GT at all?

 

[daveyboy]

Yeah its too bad. I would of liked to do this. But I think im better off. Some times you get a car that just doesnt want to work right, I think the previous owners of the mazda didnt take care of it. However if some one wanted to do this project on their own I would be more than willing to do the work (they buy parts) I even have a rear mount that I would be willing to donate for the project.
As for the GT The first thing is a upper control arm, bushing looks pretty hamered. Then a set of tires and a driveshaft saftey loop. after thst a tune and some intake and exhaust pieces and maybe even nitrous....looking for 12's with no bottle. Should be easy since it is a high 13 to low 14 second car already.

 

[phunky.buddha]

12s on a Mustang GT is cake.

 

[daveyboy]

MMMM cake
