General LSX Automobile Discussion - Free quick and cheap mods inside

Here's a list of a few easily forgot mods
Dragstrip mods (next time your going to the strip try these)
1. Spare tire and jack removal- all together it weighs 37 pounds, WTF GM?
2. Remove back seats (few bolts, easy)
3. 1/4 tank mod- easiest mod, run under 1/4 of gas, with the gas prices, your tank should already be there...
4. !Floormat- sometimes the floormats ride up under the pedal, preventing it being "floored" just leave it at home

Tune up mods (next time you do the tune up)
1. Seafoam or auto-rx, stop putting this one off, your engine needs to be cleaned! Removes sludge and build up, even cleans fuel lines if you do the whole treatment.
2. Synthetic oils- a little more expensive than normal oil, but IMO better. Royal Purple claims its dyno proven to add horsepower. They also have gear oil for the rear diff. might be a good time to change that one too.
3. Indexing plugs- now I haven't tried this, but supposily this helps. Mark the side on which the "open end" of the spark plug faces. Install them as you normally would, except when the plug is hand-tight (that is, you've screwed it in without a ratchet as far as it'll go), use your ratchet to tighten the plug until the open end of the plug, faces the intake side. Hey every little bit helps!
DD mods
1. Free ram air mod- done by removing the plastic from the bottom of the airbox so more air flows into your intake. Just make sure you leave the center "bar" or your filter will not stay in place. http://www.installuniversity.com/install_university/installu_pages/freshman_year/free_ram_air_mod.htm
2. Throttle Body Port and Polish- you will notice this one, this is by far the best mod you can do for the buck. Its free, all you have to do is read a write up and own a dremel. Also make sure you do the TB bump stop mod. This is done by grinding the bump stop on the side of the throttle body, making it actually open up all the way.http://www.ls1tech.com/forums/showthread.php?t=520845&page=2

3. TB bypass- done by removing the hoses that connect to the bottom of your throttle body, and connecing them together. http://www.installuniversity.com/install_university/installu_pages/sophomore_year/tb_bypass.htm
4. Short Throw (for the 98-02 M6 cars) here's a cheap short throw for $25 shipped, I have one and I'd pay much more than that http://www.ws6project.com/user_stor/catalog/product_info.php?cPath=235_79_34&products_id=628&osCsid=90da291227c82597bfa896f49c859b7b

just a liitle quick reference to help :D

I'm doing the seafoam for sure this spring when i get the car back out. Also I've read alot about pulling the air filter at the track helping out, haven't tried it yet myself but maybe another one to add to the dragstrip mods. Just remember to put it back in before you leave!

Wouldn't running seaform on a high mileage car run the risk of causing blockage?!

Thinking about doing a FULL seafoam treatment on my '02 car in the spring. It's got 73k miles.

Just did it on my 99 WS.6, 78k miles. Ive noticed a slightly better response, and I THINK ive gotten a mpg or two out of it.

Sea foamed my 120k mile Z28 and really only got a puff of smoke out of it... dunno, guess my engine wasn't that blocked up.

3. Indexing plugs- now I haven't tried this, but supposily this helps. Mark the side on which the "open end" of the spark plug faces. Install them as you normally would, except when the plug is hand-tight (that is, you've screwed it in without a ratchet as far as it'll go), use your ratchet to tighten the plug until the open end of the plug, faces the intake side.

:suspiciou

oh really........?

hmm i like !floormat, interesting :jest: and for the !fra you also cut the plastic underneath the air tray per www.installuniversity.com

Do a search on Seafoam and read "Choco Taco's" write up its very informative and interesting, I think there are even a couple vids also. I do mine about every other oil change. Oil drains out pitch black!!. $.02

Im thinking about using the seafoam treatment soon. 37 lbs for a jack and spare tire? good lord

but that one time you take out your spare and jack..you'll get a damn flat...been there...f*cking irony

but that one time you take out your spare and jack..you'll get a damn flat...been there...f*cking irony

Aint that the truth..
"Why didnt you have it in there?"
-"cause it weighs 37 lbs for the combo... now please bring them back to me"
Ugh. :bang:

Free mods:
Ram Air- Cut the underneath part of the lower air box out!
TB coolant bypass: Just block it off.
Bump stop: Gring the bump stop on the throttle body so you can get the throttle body to open completely. Use an OHMS meter and jab positive terminal inside the blue wire at teh connector and the black side of the meter at ground. and keep on grinding the bump stop till when you go WOT the ohms meter reads .70. An actual 90* is .71 but you dont want to go to far, bc then you will have idling issues ;).. I went to .69 .. hope that one makes sense. Just a cliff notes version.



lightweight free mods are:
Front/rear bumper supports.
and what you all said.

there ya go. :D.

hmmm i could see sheading weight for bumper supports until i got into a wreck....then what

Wouldn't running seaform on a high mileage car run the risk of causing blockage?!
I say better late than never... how many miles? I've heard that cars with stupid high milage, the gunk in the engine actually holds everything together, lol. Anyone else have any other free mods to add, Im thinking of doing a complete write up on all the free mods and installations

Where do you get seafoam?

At any autoparts store should carry it, or buy it online http://www.seafoamsales.com

If you don't seafoam your car especially higher mile cars your a tard!

I have been using this stuff for years. I just did my 153,000 mile LS1 Formula and it was incredible how much gunk was in my motor/slash lines. Car ran like a top after a good seafoam/seafoam deep creep combo. Also removed the Air/EGR to help.

Indexing plugs does work but isn't really practical for anything that isn't a true race car. On a few of the race cars we've done this on we gain about 1-3hp but when you're deep into the single digits and money is on the line, EVERYTHING counts.

Get some run flat tires....lol

Get some run flat tires....lol

do they make any for performance or for just running from the cops? :jest:

I can't wait to do the seafoam treatment on both cars. Sux I just changed the oil on both this past weekend. And the free mods are on the to-do-list.

No! Don't get run flat tires. Run flats are heavy, that is why they were the first thing to go on the Z06 when it came out.

Drive to the strip with your spare and jack. Remove it at the track, then drive home with it. :D

i drive my t/a about every other day so i keep the tire/jack and emergency kit in the car.....but like kens_ss_4 said, just take it out when ya need to

Fine take it all out and get AAA Plus thats what I did.

Good stuff, thanks :thumb:

get a 2lb compressor, 1 lb for two cans of fix a flat, and get a 1 lb tire plug kit with a set of pliers just in case. 4 pounds to remove 37. most flats are caused by a screw or nail. you pull the fucker, clean the hole, plug it, and air it up. fix a flat is for when you cant find it or inclement weather. then get the tire off when you get a chance to get that shit out of there before it starts eating away at everything. i have had a flat and still didnt use the spare bc i was prepared.

for how big of a PITA that would be, i'd say its not worth the 1-3 hp.

i have thought about doing the seafoam a long time. has anyone heard of anything negative happening to anyones car after doing the seafoam?

the worst i've heard was it restores performance and makes the car run better:D
