Free HP, most everyone knows this but whatever Options

[SlowCelica94]

I'm pretty bored at work. But for you new guys who want some free horsepower, here's a few tricks to going faster. These mods aren't specify for celicas, but any car. Pay attention to if your can is OBOI or OBOII. It changes by year on 6gc's.

~Lighten Interior - When going to the track, for best times and less weight of course, take out trash. If you want to strip a small amount of time here are some things that can be done to take off weight........
1.)Take out seats
2.)Take out floormats
3.)Take out spare and tools(you can wait till you get to track for this)
4.)Be sure you have taken out subs/amps.
5.)Take out trunk carpeting and back seat.
6.)Remove Headliner and overhead power accessories...etc. Weight saved from your top center of gravity is the best weight saved.
CAUTION: Weight reduction can and most likely will move you from a stock class in an Auto-X competition.

~Adjust Tire Pressure
If you find yourself getting a lot of wheels spin on hard high rpm launches try this. Take your tire pressure (probably around 30+) and take it down anywhere from 5-the least you are allowed to run in the given tires. This will provide more bite on cars that need it.

~Free Intake Mod.
-To Remove your Air Intake Resonator....Most are found in the inner fender wall off your front fender. Locate your intake and find out where the filter is. Look to see if connected to a pipe that goes off to either in wheel well or wraps around front of car like a horn.(not the pipe that goes towards engine. When you take out either of these, it will allow more air to come into your intake and if it is taking it from your fender, it will be cooler more dense air. This will allow better combustion and a slight increase in power and more ricer noise. If you install a K&N or other "Drop in" filter at the same time, you will notice an increase in power.

~Parking brake mod for the rally drivers
For better rally driving if you use your parking brake, try this. If you have a normal handle parking brake, push in button and drill a hole across the shaft through the button. Then while depressed, stick a cotter pin through that hole. This will allow you to pull up on the e-brake and create a slide when you need to rotate the rear around. (Not recommended for on road use)

~Slight Ram air
Take dryer hose and run a tube from your intake hole/cone to a free spot in your grill or front of car and have air ram into your intake. It creates about 2-3 psi at 45+ mph.(if done correctly)

~Throttle Coolant Bypass
Very common trick with domestic cars. Take the hose running from the radiator to your intake throttle body and disconnect it and bypass it. The hose on the other side should be connected with a coupler. This will allow your car to run without your TB heating up and causing warm intake air.

~Another Ram Air Mod
This trick has proven to be helpful at the track many times. In many cars you can find the stock airbox/filter location to be right behind a headlight fixture. If you take that headlight fixture out and leave the filter exposed to the incoming air, you will gain a lot more cold air and air to the filter. This has been proven to take time off your E.T. at the strip.

~Throttle Cable Adjustment
There is a lot of slack in the cable that opens and closes your throttle body. This is great for traffic and daily driving. To relieve the slack, you should get a set of wrenches and see the adjustment to the cable where the two nuts are. Well loosen the nuts in the appropriate direction to reduce the slack. Start your car up and check the idle. If everything is good, then go and check for throttle response increase.

~Gut Cat on Pre-OBDII Car
The less exhaust restriction, the better. Unbolt your cat from your header(s) and the rest of your exhaust. Proceed to knock the entire contents out with a screwdriver, a drill or whatever you can find that will work.

~Exhaust Removal
Unbolt your exhaust at your header, or behind your cat. If you want ultimate convenience for replacement, try just unbolting the rear most portion, often referred to as the axle-back portion. This mod will allow for more flow of the exhaust. Top end breathing and power will be gained while some low rpm torque may be moved.

If you break something, I'm not responsible. But if you're careful, you'll be fine.

How easy is it to take out the back seats in our celicas?

[Supersprynt]

Its easy, the bottom portion pops out, the rears you need to unbolt from the hinges, 2 bolts a piece. The top pieces need to be removed before the bottom.

so I was planning on dropping the muffler anyways, it's pretty rusted out and I was just going to leave the cat on. (plus kansas doesn't care much about emissions and all that yet unless it's ungodly loud)

recommendatinos? when i get back from mexico i'm going to bust the bolts off and pull the muffler i think

a few more things for free or almost free that i didnt know -

1. barf before you race
2. eat alot and take a huge crap
3. get rid of all of the heavy air in your tires.

Just kidding

Didn't you just make a post about looking for mods like these? Yeah.....hilarious

i was reading that article.. what does those coolent lines in the throttle body do?

[darksecret]

Sometimes the weight savings isn't the best route, one of the reasons my Sierra ran so quick for a truck was because I stripped a lot of the interior, I shaved 650 lbs. by taking out the spare tire and holding rack, jack and case, rear seat, body panels, tailgate, stereo equipment, most of the dash, and passenger seat. If I had switched to a race seat for the driver and welded in a custom dash I would have shaved another hundred pounds but I sold it and got the Celica. It still weighed 4,650 when I got finished but I was running mid to high 14's in the quarter and high 9's in the eigth, I ran with a few mid 90's Z28's and ate Mustangs up (non supercharged Cobra and slower). Point behind all this is that when I would take my truck to the races it was a chore, I had no stereo, no cup holder for my drinks, and it was pretty noisy, the only reason I had an arm rest was because I had captains chairs with them built in. Consider shaving weight but keep it functional so if you plan to carry people in the car leave the seats and if you will drive it more than to the race leave the sound dampening material and body panels in place your ears will thank you after some time, plus after a few months you'll look at the inside of your car and be like why did I do this.

Yeah, driving a stripped car sucks. I drove my car to a meet with no carpet, lots of missing panels, no stereo, one seat, and it was crazy loud. The car sure sounded quiet when I got everything put back together though.

no takers on this question?

[Bigmeanbulldog55]

I would also like to know what exactly these lines do. It makes sence to me that they are there to help cool it, but if taking them off actually makes it cooler, then it doesn't make sence. I love this topic by the way. Keep them coming.

I have one, but it doesn't always work. If you unplug the o2 sencer on the exhaust manifold, it will sometimes trick your engine into thinking that it's running lean and make it dump more fuel in. It could also make it think it's running rich and cut down on fuel though, so it's a 50/50 shot.

[rocky2006]

actually i read that the coolant lines are warm. they go to the intake manifold to heat up the manifold so there are no ice crystals or anything of that matter forming in there. if they do form, there is erratic idling i think. the coolant lines going through the intake manifold in every season except winter is pointless. it is only heating up the manifold more and therefore heating up the air passing through it, which we all know is bad for performance. ill try to find where i got this info from as im trying to pull it all off the top of my head.

EDIT: found it, but its on a mazda6 website. let me know if it's irrelavent to the celica.

I also took a look today and couldn't tell exactly which two lines to connect. Can anyone take a picture and help us out?
