I was wondering if anyone had any good modifications for their 240. I own a 93 240sx se model, and am planning on installing a new intake... Are there any other minimal mods i can do to slightly improve performance? and how much would it cost? Any replies would be appreciated.

Check nopi.com

Doing a cat-back exhaust, or simply replacing parts of your current exhaust will help. You can buy a header, bigger pipes, a higher flowing cat, and a better muffler. Nopi offers two pacesetter headers. One costs more, and is simply ceramic coated. Don't buy this. Buy the cheap one and wrap it in thermal wrap. You'll save some $$$ with the same effect as the ceramic coating.

There are plenty of other easy modifications. Lightened flywheel and pulleys, for one. Changing your ignition can be surprisingly helpful. New ditributer, rotor, and cap. These are also offered at nopi.

Replacing your cam(s?) will help too. Unfortunately, they will simply "transfer" performance. You can better your acceleration, but with a slight top-speed decrease. I don't think nopi has these, though.

Are you interested in bettering suspension, as well?

Braking! You can totally do this yourself. Should be relatively cheap too. All you need are the parts, and none of them should cost much.

Dennis, who just joined has an NSX, silver and black. I don't think he will modify it though. I want to modify my Rio. :D

Why not modify it? He should get some of the AZ parts and contact Comptech...I repeat...contact Comptech.

Does anyone know if there is any way to retrofit new 3-point seatbelts into the S13 hatchback body? Yes, those 'mouse-belts' were popular then, but they are ANNOYING now.

I've put S14 seat belts into my S13.

If you want to do it, be prepared to lose the panels by the back seat.

Best way is to get S13 seat belts out of a CDM model S13, and also purchase the accompanying rear interior trim pieces.

The S14 seat belts bolt straight into the S13, in part due to the two cars having the same thread pitch on the seat belt bolts. Be sure to use loctite so that the bolts can not come lose.

Weight savings 100+lbs with the Up graded cams should add like mabey a solid 15Hp advantage

so you do the physics total hp advantage is going to be 25hp

Very nice. Why is your username 'dieselpower'?

ok, my girlfriend has a 240SX 92 i know nothing about them, i drive american cars =) but im willing to take the time to make sure theres just one less stock car on the road...plus i love her =) ok she wants her car to go faster, i heard you guys talking about replacing panels and shxt to reduce weight, trust me, your cars dont need to lose weight, or atleast it shouldnt be a high priority, about a 100pounds knock off .01 or .1 seconds offa 1/4mile. im not so familiar with the engine set up either, could you put an open element in there? and also exhaust, theres some pacesetter turbo whatever monza thing for about 150, and some pace headers for 150, you can also get a exhaust dump for a V4 for like 60$$ at exhaustcutouts.com might be 50$ im not sure, but it gives a nice gain. well heres what im planning on aproaching her with, tell me what you guys think.
cat back exhaust,
heads
improved air intake, manifold a maybe,
maybe change the cams
not going to tell her to get an exhaust dump, a 240sx should never sound louder than a camaro....lol...well ok, could someone tell me what they think, and what companies supply this stuff? any help is appreciated, i only know where to get stuff for GMs thanks

As far as weight savings go, lightening of the powertrain would be quite helpful (albeit expensive) allowing quicker response. I knew a guy with a 240 with only aftermarket intake, headers and cat-back exhaust and it made a decent seat-of-your-pants improvement, unlike some Hondas where the cheap bolt-ons make little difference.

ok, to the drivetrain is understandable, but paneling, carpeting consoles, that stuff should stay in unless its a strip only car.

yeah, what he said. don't be takin away comfort and convenience.

Yeah, no kidding. People should leave in the interior panels especially. The vinyl, plastic, etc. is designed to aid in safety; you wouldn't want to get skinned by an exposed sharp metal edge.

i do...

he he .:bloated: :buck :huh: :silly: :toothless :ylsuper

you want performance?? fine...here are the primary things that you will need (and for those of you who said he should get plexiglass windows??? HE IS NOT A PRO DRAG RACER!!!)
anyways here we go (all mods are for NON-turbo and MANUAL TRANSMISSION only):
KA24DE is a DOHC there for
- replace both cams to aftermarket..lightened...
- nismO short shifter
- lightened flywheel
- carbon-fiber drive train
- nismo strut/tower/sway bars
- injen intake with HKS aftermarket O2 sensor and hi-flow B filter (those big round filters that are primarily seen on 3z's or rx-7's..yes they work on 240's)
- any aftermarket pressure plate
- rims not exceeding 17"...anything higher will slow your car down..
- I suggest the lightest rims you can find (therefore do not get CHROME)
- koni adjustables..lighter...good for pick up...
- eibach spring works will complete the suspension
- port-polish
- DC headers
- I suggest GReddy extreme exhaust
- sleeving your block
- performance spark plugs
- wider silicone hoses for ignition wires
- MSD ignition
- aftermarket intake manifold (i believe HKS or BLITZ makes one..i forget)
- if you don't mind going without air condition..replace fan belt and place electric fan (relieves tension on belt)
- boreing out your pistons...new rods
- and most importantly...performance clutch..if you're not a pro at stick..get an 8 puck...it'll make a BIG difference on a launch

:eek: What? Honda aftermarket parts! DC headers?

With the parts you mentioned:

- sleeving your block
- performance spark plugs
- wider silicone hoses for ignition wires
- MSD ignition

...won't do jack without forced induction or higher compression plus an upgraded fuel system (injectors, pump, controller).

- injen intake with HKS aftermarket O2 sensor and hi-flow B filter (those big round filters that are primarily seen on 3z's or rx-7's..yes they work on 240's)

...you mean, HKS VPC. (lol, the part about the filter made me laugh--all filters work on all cars with the proper adapter).

And don't forget a ROM chip upgrade to finish it off.

HEY I WAS WONDERING WHAT IS AN EXHAUST DUMP???
PLEASE LET ME KNOW
THANK YOU:devil:
EDGARDO:evillaugh

that a 5 spd model?

I would get a better clutch so she can drop it off the line harder, I assume she wants to be able to beat the hondas more. For more street applications certain things are better then others to modify first.
You can always start with the intake,
Buy larger diameter Throttle body and Mass Air Flow meter.
Buy a cold air intake system with cold air induction
anything to let more air avaible to the engine.

Now you have more air comming in focus on getting it ou in more volumes. I wouldn't nessecarily buy a header first off, spend it on a nice catback exaust system and test pipe to replace the catyalitic converter if your able to in your state.

Theres some mods to stay away from too that are just a waiste of money and fabled myths. I see a lot of people buy high tech ignition systems with bigger wires and better plugs. Fact of the matter though if your engine is pretty much stock you don't have to mess with all that. Folks go buy nice expensive MSD ignition boxes etc... for nothing. Also if its pretty much stock hp(which I consider with the current mods I have listed so far) Bigger fuel injectors, fuel rails, fuel lines, and bigger fuel pump would also be a waiste of money almost and be good to stay away from for awhile.

If you might get a stage 1 clutch or something a bit better then the stock clutch might as well put in a lighter flywheel at the same time, also underdrive pulleys are nice too if you can put those on yourself.

:shocked:

Well, an exhaust dump is a simple metal split pipe piece which attaches to your regular exhaust system before the muffler. Once installed you can control whether you are using your muffler, or using a direct straight-pipe. This control comes from the placement of a cover plate over the straight release port. A few manufacturers sell exhaust system kits with this feature included, eliminating the necessity of integrating another metal piece into your pipelines.

Here is a photo of one example:

I have to definately concur with the idea of a decent performance clutch. However, I don't think I can totally agree with larger diameter throttle bodies and such. I know they are great mods with underrated value, but a 240SX deserves much more. If you can afford to get a top-of-the-line exhaust system + intake system + throttle body + MAF sensor (even from another car), you might as well start off with a decently priced SR20DET (about 2 grand assuming it is installed by someone you know or yourself). Starting off with the platform you want is a good idea as it will save you money in the long run. Of course to have all the flow control done plus a turbocharger later will yield great results overall, but besure you start of on the right foot and don't waste money (i.e. don't buy an expensive AEM Intake or CAI system if you are going to get a whistler; just buy the filter, since all the pretty mandrel bent piping won't do you any good after you get a turbine.

he didn't mention dropping in a sr20, he wanted to know a few mods to get some power on his girlfriends car. Opening up your air intake and exaust is a great starting point for your car, any piece you can get with more diameter is usually good. MAF, TB's, Cone filters, intake piping... Catback exaust, get rid of the cat if you are able to that robs you off some top end power, and gives your car a bit more growl if you want it, then Id get some headers if I had a NA car. Underdrive pulleys, cam gears, and a better chip are a few easy starting points to do things on your car to get some power without being too radical, most of those parts are bolt on and easily done if you have some knowledge and tools. Try to stay away from parts where you will have to modify things, I try to get bolt on parts that are designed specifically for my car, might be a bit more expensive that route but you will save a lot of frustration installing it and in the future if you change other things that involve that part..

Oh I wasn't aiming my suggestions at any specific person, just commenting out loud in general. The guy with the girlfriend hasn't responded in about 9 months, so I figured I might as well respond to whatever you all have to say. And I still have to stick with the idea that it would be better to find a cheap DIY deal on an SR20 than buy a series of expensive bolt-on kits. You say that you would "try to get bolt on parts that are designed specifically for my car", but that statement as innocent as it may sound gives off an essence of irony, in that the KA24DE isn't even designed specifically for the 240SX.
