I started the day off realizing how much crap is in the back of my 240. I had two 10" sealed box woofers that i built, and the full spare tire/jack stuff. I decided to put her on a diet, i removed the carpet, all the spare tire stuff, one of the 10s. Estimated weightloss, 75 pounds. I felt that difference quite immediatly. With such a low power motor and a generally light car, removing 75 pounds results in considerable power increases, as well as handling. So with a single 26 pound 10 and an amp in the back, she's much lighter and the sound is still top notch. Then i decided to have fun with my Intake. I removed the whole bottom half of the factory airbox, i set it on my table of junk removed from my 240. This is where it gets pricey, i bought a 7 dollar new air filter, and caulked it onto the top half of the airbox. Results: The entire air filter is exposed to the air, is fully sealed, and is brand new. I assume its breathing a little easier. But the cool part is, w/o the complex bottom airbox on you can really hear the intake past 3k. It just sounds awesome when im flooring it now. Power is up due to the weightloss and new filter. It rained TONS tonight, and i stupidly drove my car very hard, hard enough to put it into a few drifts with 225s. It was good times, and when i got back i felt the airfilter, it was still on and bone dry, even though its fully exposed to the engine bay and i was driving at the top of 3rd and 4th in some massive rain. Its been a day where me and the 240 bonded just a little more. I love my car.

[krazy skwerel]

If it is unintentional then it's not drifting. I bet 225's look good on the car. I really don't think I've seen anything more than 205's that I can think of right now.

[dareo]

I wasnt trying to drift the corners, but i thought its fully possible that i might swing the back end out. Cornering at speed, modulating the throttle in 2nd, no clutched drift attempts. I love the look of my 225 series Sumitomo HTR+, and the wet performance is surreal. 225/16s on an S13 gives a real beefy tire look, as opposed to a 205/17 or 18. I can literally slam my brakes in the pouring rain and either not skid at all, or skid very little. Some dork in a camaro-esque car was all revving on me at a light..either he was just revving to be a dumb and not wanting to race me at all, or he had no holeshot in the rain. I hook up immediatly after a 3k clutch dump and effortlessly beat him to the speedlimit, (45mph) i strictly cut street races off at the speed limit, or a little over if its a nice dry road. He had to have been racing me because after i let off, he comes passing by, speeding pretty good.

[Hellion240sx]

so how are you gonna take it off??? when it comes time to change it?

[krazy skwerel]

I love wide tires. They give a car such a good feel and look.

[dareo]

It may just be my mind at 2:30 am, but take what off? Change what? I dont understand

[krazy skwerel]

I think he means the air filter.

[dareo]

Oh duh i just got it. The airfilter. I figure a filter is good for at least 10-20k miles and by then i'l be running CA18DET. If not i can scrape the caulk off and put a new filter in.

[groundhogday1976]

You could just take your inner fender out and remove the intake resonator if you want the cool noise at WOT. Then you won't have to worry about caulking your filter on. It might not be as loud though.

[BuudWeizErr]

Most people just cut a huge hole in the bottom of the air box and then bolt it back together, so that the bottom of the box holds the filter in place, but I guess your way works too, hehe.

[Bubba1]

I'd put the carpet and spare tire/jack back. 75lbs less will result in less than .1 seconds improvement over a 1/4 mile. We're talking a barely detectable difference. Also bear in mind drifting is hard on tires, so you're increasing the likelihood of having a tire problem. So you'll regret not having that spare and jack if and when a tire problem happens. Plus the interior's gonna look like s*** without the carpet. IMHO.

[dareo]

its just the cargo bay's carpet. And its fully concealed unless the hatch is open. I still have the rear tray in my car. After my weight reduction, the car has a very noticeable difference in how it drives, the rear even looks about half an inch higher. I need a good suspension.

[Bubba1]

If you take a performance driving course, you'll quickly learn thatyour 240sx's motor is in more need of improvement than your suspension. 240 stock suspensions are much better than you think. But If your car's rear raises significantly after removing the spare tire, chances are you have a rear suspension problem and should have it looked at.

[dareo]

My suspension, compared to my friends 240, is awesome. But it still probably sucks. It seems to ride pretty nice, i wasted my friend on this sorta bumpy two laner we did yesterday, he just couldnt keep his rear end in check at speed.

I like to think my motor is okay and sorta powerful, but i know its really not. But i like to think it is, at least untill im hearing the blowoff valve.

Thats cool..

But I dont have anything in the rear , including the rear seats or speakers of any kind.. hehe

Just a quick suggestion, if you wanna drift it is much easier to drift with 195 tires instead of 225. But then again 225 will hold you on the road more, But thats just me im a drift maniac.

[midwestdrifter]

im not trying to be a jerk, but i have a hard time believing you lost 75lbs from the spare, carpet, and a sub. maybe you should weight the spare.

[4felix20]

my sub and box alone weigh almost 50lbs. add a spare and a jack to that, i see 75lbs EASILY. i've been riding without my subs lately...

[midwestdrifter]

wow i never knew that subs wieghed that much. thanks for the info.

[krazy skwerel]

That damn 3/4 inch particle board is some heavey stuff. Even the 1/2" is bad.

[dareo]

My subwoofers are JBL GTO 10", they have a pretty good sized magnet and handle 1000 watts. But i built the boxes myself, thus they are almost overbuilt. 3/4" MDF glued and screwed with plenty of sealant on all edges, plus carpet and a grill=26 pounds each.Anybody know how much the rear seat weighs? Its crossed my mind many times to remove it.

[huckedup16]

Backseat is prolly only like 15 lbs

[AZhitman]

Sounds like fun, dareo - I say more power to ya!!!

p.s. If you think 225's look good on a 240, you should see one with 245/50/16's!!!

[dareo]

245/50/16 is way too big for an S13. I would love to see it done. Good luck fitting that up front with any kind of suspension mod

[sixxdeuce]

I have some of those sumitomo hrt+'s on my car now in a 245/40/17 size. They dont feel quite as solid as the kumho's and Hankook's I have used before like the sidewall is not as stiff. I think I will play with the tire pressure a little, they are fairly low at around 35-38 psi which seemed perfect for the other tires ive had but I think these are rated at 51 psi max where the others were 44psi, so maybe they are ment to run a little higher. The main reason I bought them was so I could rotate side to side since they are non-directional.

[dareo]

They may not be the best gripping dry tire, but they are impressive in the wet. I can slam my brakes, fully slam them, in any kind of rain without skidding. My brakes are stock and work normal. Car just dives a little and stops. I have to really push it to throw the rear end out. 225 series is a lot of rubber for a stock KA. I'm going to live with random snowings here in Utah, usually theres not more than 5 a year. It rains, and wet weather and powerful RWD is just a hassle. So i went for Ultra high performance all season. The HTRs do a great job, and i think there about the cheapest tire in its class on Tire Rack.

Mine were mounted with 33 PSI, i upped that to 37 and they grip more. I haven't tried higher numbers yet, but hey looks like i've got something to do tomorrow.
