Superlight S13 - No 56K!

I straightened my hood some and grabbed a hammer and a tin snips and attacked the bracing on the under side. I also used my dremel to chop off a non-essential part of my throttle body. The end result is that my hood now closes and latches with the V8 underneath. The locals will be none the wiser.

I received my mishimoto radiator in the mail too. It will be relocated to a forward leaning spot inside of my bumper once I figure out what I am doing with my header panel and my headlights.

I also found and installed my valley cover and found that my stock throttle cable is the perfect length and fits the GM TB like it was factory. Beautiful.

You guys love pictures, right? I sure hope so because I have plenty.

Open. Love the two tone racing hood. :p



Closed. You can hardly see the dent I had to make.



This would have plenty of room like this. I am relocating the radiator either way though.







B-E-A-utiful.

GREAT SUCCESS!

Also those mounts look pretty beefy I like.

I am honestly counting the ounces I am shedding from the car. Not one single thing avoids scrutiny for possible weight reduction. Not my serpentine setup, not my brakes, not the steering wheel, etc, etc. It still has to appear like a stock economy car though, and be safe to drive.

I am now thinking around 2300lbs ready to run with the V8 is entirely doable. In a car hopefully as quiet as a new camry.

I also have a tough 1/16'' T6 aluminum 90 degree L channel in the mail from McMaster-Carr to replace my header panel/radiator support with. I will also be deleting my pop up motors and going solid mount for the lights, as well as running some sort of stealth hood pins to save some weight from the latch setup.

2 questions-

1) What headers are you using?

2) How do you plan on making the exhaust quiet?
I wanted mine quiet too, but couldn't see a way to do it with space requirements.

The headers are a custom made set from a shop in Texas. I believe they are 1-5/8 tubing with a 3'' collector flange. They are fairly well made pieces.

To keep it quiet is going to require some creativity. I was originally thinking of having one or two resonators in line, as well as a baffled OE style muffler, which is tricky to find in 3-3.5'' piping. I am searching through high-po V8 stock setups as well like the G8's and 'vette.

I think I may end up going from 3.5'' piping through a resonator and back into my Walker 2.5'' muffler. I know that this will keep everything quiet, yet on a V8 the loss could easily be 15+ HP.

Finding a good flowing lightweight 3'' muffler not designed to be loud in some way is like finding unicorn poop in a pot of gold.

Do they have a name?

Are you running a Y into a single? I have 2.5 dual all the way back.

thats cuz your the unicorn shit(unique and awsome)

Couldn't you use (like you were saying) a stock G8 or GTO Muffler, and maybe do an electronic exhaust cut-out on the exhaust. and then add an additional muffler/resonator? then it's quiet when you want and has one hell of a bark when you want to awaking the cops.

I dunno about the shops name. From what I gather they were a one off set for a drift car.

I will probably run a Y into a single to keep weight and complexity down. If I can work it in I will run an electric cutout wired to my now defunct headlight open switch. (Popup delete) Putter..putter...putter...

At this point I still need ~4K further invested into the car before it's driveable. And that's with used parts wherever possible.

MADRE DE DIOS

Yesterday I purchased a standalone LS1/T56 harness to be made for my setup, mainly just to reduce any possible issues down the line. One less thing for murphy to jump into.

Also, did I post this before?



Kidding! I bought that vortech for my town car and found it won't work so I mocked it up on the 240 for fun.

I also have my cooling system condensed down as simple as I can and still have it work with a relocated radiator. Confusing, eh?



Note, the pic isn't mine. I borrowed it off of pirate4x4.com.

Relocated to where?

Leaning forwards, inside of the bumper. I have a picture saved somewhere of the setup I am thinking of.

My header panel is so tweaked that it will have to be chopped up to fix, and I can save some weight in the process.

Ok, when you said relocated, I had visions of a roof or rear mounted rad.

why kidding? put that shit on there haha

Nah, too much extra weight. If I were to need more power than I am building for, an LS3 or LS7 is the only thing I would have my eyes set on.

I think you guys have hardly grasped the surface of how detailed the weight savings are on this car. I could only really explain it fully in person.

I have this setup on order (Since august of 11'....). Currently waiting for the rotor hats and caliper brackets to arrive. With the 2 piece rotors and Wilwood 4 pot superlights it should be around 30 pounds lighter than a Z32 setup up front, and perform much better. Yeah, I have about 1K into my front brakes alone.

if your being such a weight whore, why bother with having any interior? Just make a tin kit dash with the basic gauges, throw a seat in, gut the doors (rivet lexan in for windows), throw away the fake radio bs(extra "grams"), and start carving the floor out of the rear for a 5-10 gal fuel cell. Seems like its a lot of bolt on weight savings where you could really lighten the entire car up with more effort.

Just my $.02 so dont be mad

Either way keep up the work

exactly^ counting grams in other places is pointless if you have all that garbage still.

It isn't pointless. It's in the car to be looked at by people like you to say, "this isn't a race car, it has full interior", and then have him hand you your ass. You're welcome.

This is being built as a sleeper so I agree with Jim on this one. Correct me if I'm wrong speed_demon

Looking real good bro... Cant wait to see the final product

Exactly. It has to retain some semblance of looking, at least at first glance, like a basic every day commuter or economy car. It has to fly under the radar.

I am also looking into lighter O.E style seats, as well as replacing the trunk floor with a large sandwich core piece of carbon fiber. In doing so the car still has to be reliable and drivable, as well as pass any track's safety inspections.

I will also be tinting the rear windows some to keep the back seat hard to see. I am thinking I will just lay down some cloth on anything that would look out of place at first. If it starts to look like crap then I will just put the old interior back in, it weighs less than 15 pounds total including the back seat anyway.

There are trade offs with everything on the car, with most of them being high cost or usability of a light weight item. Take the lexan windows for instance, I would save about 5 pounds per window, and they would scratch and need replacing every season if I wanted to run them on the street. I will make my own light weight carbon fiber hood and save 25+ pounds and still retain full functionality of everything else. I am shooting for under 8 pounds for the hood.

Also, for anyone curious I made a post detailing the cost to weight savings for common aftermarket 240 parts. It shows you where a specific or similar part lies in relation to another. Funny how wheels came out the worst, and the battery the best $ to lb. - http://www.nissanroadracing.com/showthread.php?t=2880

Anybody want me to copy that over to here?

I believe thats what hes going for... This thing is gonn haul ass
