Also, I had to post this too. My town car is close to the exact opposite of my 240. 4500lbs curb weight, with 20 gals of fuel and a passenger it could easily top 5K.

Power everything, auto everything, even friggin automagic rain sensing windshield wipers. This is my DD. Laughing



Kouki, the CF hatch weighs about 5lbs less than the steel unit. Most of the weight is in the window. A lexan unit is a possibility for the future.

Here is a shot of the basics for my interior. I have since done a lot more weight reduction on the easy stuff, like skinning the wiring to remove the stereo cables and removing the panel that holds the jack. IIRC, I lost more than 10lbs total from switching to manual seat belts as well.



Partially removed. This was a real pain to cut out, also note that it is not integral to anything. It is not necessary to retain this unless you are keeping a jack or radio antenna here.

See the spot welds started?



My first real weight reduction. I removed the aesthetic only rear spoiler and saved 7lbs. Very little rust under here, and I capped the holes temporarily with some simple hardware I had laying around. Doesn't leak either.

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

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.


tint the windows dark and people will never look inside. Also i thought the point of a sleeper was to look stock/slow on the outside. If your look slow outside whos really going to care what you have inside. People will just think your some punk kid following trends. Then hand them their ass.

Just said what i said since you were trying put your car on as much of a diet as possible, and thats just one more way.

Don't worry about it, everything on the car is fully thought out. I am doing the absolute best I can with what I have.

Copied from one of my other build logs. I missed a few updates in the sequence.

I realized something earlier today as I was pricing out what it would cost to convert an LS7 to a wet sump oiling system. I am basically trying to build myself a shelby cobra-esque car making it as light and raw as I can using the Nissan body in sort of a wolf in sheep's clothing style. For many different reasons I want this car to stand out as little as possible, so the fact that these 240s are often mistaken for probes and come factory equipped with 140hp works to my advantage.

I have found that in many cases a well laid out plan is the foundation for any good project, so I am assembling a basic blueprint for future progress.

My main criteria so far are:
I would like this car to be under 2500lbs with the V8 engine.
I need this car to be mechanically sound and daily driver reliable - Although it will mainly be a weekend vehicle.
The exhaust must be as quiet as most new production sedans (with the cutout closed, if I use one).
I would like it to look like the LS engine and anything else under the hood is original equipment - No chrome or obviously out of place items.

I am figuring for an area of 6-8k with an LS1, 8-10k with an LS3, and 13-16k with an LS7 installed in my car, fully complete driving down the road. I am still not sure of which one to go with. - I have decided to go with an aluminum 5.3 for now with an LS7 in the works for later.

Each one has it's strengths and weaknesses, but a 7500RPM 427 is a very hard thing to pass up - Even if I have to save my pennies for a few years to buy it.

And of course I have more pictures. This is a Speed Racer license plate frame. I just had to buy this, really I did. I think it's hilarious given my nickname and the way this build is going.

The general idea of what my acc. drive will look like. Add in a 5lb race alternator off to the right side and it's complete. Very simple.



The coil and rail issue.













I've got my coils all in a row. (ducks in a row..)

Notice how clean and blue those wires are? They, along with the spark plugs and coils are just cleaned up factory originals. Why waste money on something that doesn't need to be replaced?

Sweet build. Can you take a picture of the area behind the jack panel you removed? I've always wanted to cut those parts out.

i understand what youre going for. but if youre going through all the trouble i would just take the interior stuff out too. (thats just me) most "ricer" kids gut out there cars anyways to look cool or whatever, most people wouldnt think to much of it. looks like you missed some tar on your wheel wells too! Razz im all or nothing type of guy though. i think once people hear the car running all bets are off anyways. its pretty hard to quiet those big motors down to stealth status.

you could go to a waste spark and remove 4 of your coils. that should be worth a few pounds. jk.

i do love the concept of your build. i am a huge believer in adding simplicity and lightness to my race cars. so keep it going!

77, I will have a picture up for you shortly.

93, I considered going with the fairly uncommon one off set of carbon fiber valve covers for sale on LS1tech right now, and those along with a set of harley davidson's lightweight ignition coils would reduce a measly 3-6lbs for around $1K.

I could take a dremel with a few cut off wheels and a $10 bottle of booze and chop that much weight off of the engine block itself before I passed out, so for the cost it isn't worth it.

I think you should go along with you act to pass it off as a Ford probe by putting the emblems on the car

I don't do stickers though. I briefly considered a few autozone special edition/V8/turbo emblems, but I couldn't do it.

The car is black and dented up in a few places, enough so that it will pass off as an old crappy car either way.

Yeah I am not a fan of stickers either. I just put that out there as maybe ssomething to help throw unsuspecting people off. I'm not a big fan of Ford either

Did I just drop a Benjamin on bolts?! Shocked

Starter motor, clutch, PP, Flywheel, harness, a bunch of bolts, and clutch alignment tool are all on their way. I am still working on finding a trans.

Shameless plug - Check out my FS thread. I need these things out of the way so I can finish up my build. http://wi240sx.omgforum.net/t734-v8-swap-almost-done-have-lots-of-stock-parts-fs-cheap#12690

Any guesses as to what I have total into the build so far? Wink

I just purchased a full F body LS1 T56 pullout on LS1tech. I bought everything from the flywheel to the output shaft.

All I can say is that I hope it works for the cash I just spent. +3K to the build just the last two months alone.

Surprised Thankfully not yet. The aluminum 5.3 itself, after the Acc's on it sold cost me $266.96 out of pocket. Not including the LS1 manifold and other things of course.

The total I have so far, with the car's cost itself, the 5.3, T56, etc, etc. Was $5200 Not including the sale of the old KA parts.
I am somewhere in the high 4K region if I include sold parts.

My uncle offered me a handsome price for it and I started laughing. Couldn't help it, he was offering me 4x what I had just paid for it. Maybe I'll sell it cheap on here once I go LS7.

Sorry, deleted post on accident. A cheap 5.3 would be great for my buddy.

LS3 clutch kit, T56 bellhousing to block bolts, PP to flywheel bolts, and the yukon 5.3 starter have all arrived. I am amazed at how light this starter is, and baffled at how stupidly heavy this pressure plate is. Shocked

F body T56 with all the accessories is on it's way.

The LS3 clutch disc itself is just shy of 5lbs, the flywheel is 25.5lbs, and the pressure plate is 25lbs of beefy but unnecessary steel. No
