Best guess, how much weight would I loose if I stripped the rear seats, carpet and sunshade? I would probably recarpet and I don't want to remove the sound deadener. I also plan to relocate the battery to the back and remove the spare tire.

OK, I answered most of my own question. Here is what I have so far:

Spare tire = 35lbs
Top cover and tool bag = 8lbs
Jack = 6lbs
Rear carpet = 10lbs
Sound Mat = 9lbs
Seat Back w\Cargo Cover = 20lbs
Cut off bumber struts = 2.75lbs each x 4 = 11lbs
Seat bottem = 6lbs
Replace stock exaust system with 2 1\2" performance system = 30lbs
951 radiator and slim fan net savings = 4lbs
Hybred GT headlight conversion = 15lbs

Total = 154lbs

Plus I lost 2 more pounds by replacing my leaky fuel pump with a Ford unit and replacing my hatch "prop stick" with a length of PVC! Grand total of 156 pounds!!

I had my car weighed a couple weeks ago and it was 2560 lbs so now it is 2404 lbs or 2387.5 without the sunroof!

Data point: Sunroof = 16.5lbs

I still need to figure out how to remove the lower half of the rear seat. It just seems to be glued in. Is this true? Do I just "RIP" it out? I cant find any spring or frame work that might be attached with clips or latches.

I'm going to re carpet the back to make it look half descent so this will add back 5-10 lbs plus I still need to mount up my 14 lb intercooler plus all the related plumbing.

Todd

Edit: I've decide to keep a running tab on weight reduction here as I find things. I'll keep editing this post to make life eisier for anyone who wants a list.

the lower part is glued in and has a bunch of metal clips along the top edge, under the top section. It really only ways maybe ~1 lb, which is about what anything that goes in its place to cover the whole would way so there isn't too much reason to even bother with it. Plus, people could almost still sit in it if need be.

OK, I went ahead and pulled it. It actually weighs 6.5lbs. I can't imagine anyone sitting back there especially without seatbelts!

Alxch1n15, the pump fits most all Ford trucks and vans from 1987-95 or so. They are tuff as nails. I have only replaced 2 in y career compared to hundreds of intank units. Used units should be cheap. You can look for new. I suspect you can find one for less than $100. They are also more quiet than the OE Bosch unit. It isn't a direct bolt in though. I had already modified mine to rid myself of a leaking fuel accumelator so mine just used a barbed outlet. The inlet is smaller than the bosch but easy enough to adapt as there is little pressure at that point. Also remeber my setup is for EFI but I do run more than 65lbs of pressure on my system. These pumps will deadhead 100+ lbs. That is as high as my gauge goes.

That's awsome news about the fuel pump.The mods should put it in the Tech. section for future referencing.

Wow, did all of that really weigh out that much? I'm really surprised. Especially the rear lower seat - it's all foam after all!

Are you using a bathroom scale? Have a 10lb sack of potatoes lying around to calibrate it?

hello endwrench i have seen a replacment rear window in fibreglass in a german mag not sure if it was home made or possible to buy it looked good and would save a rake of weight .It only has a small up-right window so keeps the inside cooler on sunny days. chris

Well at GTRacing.com i know they got a hatch that is real light, so you might think about that.

A little late getting back to the subject but just to make clear I use a produce scale that has always been spot on for weighing postage items.

I know what you mean about the lower seat! I couldn't believe it either.

Found a little more. I did the "Euro Bumper" thing so I went a head and cut the rear of the struts off all 4 struts after collapsing and welding them. 2 3\4lbs each for a grand total of 11lbs. Plus the car looks better

Do you mean the factory CIS system or are you rating the pumps deadhead pressure? I don't know either but it seems, IIRC, the stock CIS system operates at something a little less than 100psi? Not sure.

If the CIS operates at 160psi and is capable of supporting 300+ HP then I am sure the Ford pump would not keep up. The Ford pump is capable of supporting 400+ HP at 60psi though.

I took out the sound deadening material, Euro front and rear bumper no trim, rear seat etc out, door panels out, no air, gutted the sun roof also, For the glass on the back panel I did make them out of Fiberglass but never put them in[ use existing glass for template], no cat, no rugs, roll bar in, radio out, may take out the heater when I move to FL., also the rear spare tire cubbie,

I have some euro bumpers avail if anyone is interested.
