Howe Racing was a nice find! Prices look pretty reasonable, too. Had you used their stuff before?

spare tire well

If that spare tire well is not rusted, I bet someone would want it to cut and replace one with holes in it...

I almost ask him about that but already have a wheel well to replace mine that has a couple holes in it.
But I bet someone else might buy it.

We finally got the cams degreed in today, got most of the valves adj. Ran out of shims for the size I needed so a few will have to be done later . for the most part the engine is done .

I went ahead and stuck it back in the car to finish up mock up of the drive train, Now I can route the cooling system , find a radiator , start plumbing the oil cooler, and fuel line

A long day with a bit of progress. First we pulled the engine back out ( its going to be out and in a dozen or so more times before it's totally done ) with all the exhaust studs I just couldn't get the headers on in the car, so out the engine came , installed the headers , and jacked the whole thing to a wicked angle to clear the headers while we stuck it back in . took the opportunity to mock up a e28 M5 radiator , and shave the rest of the brackets out of the engine bay .

001.JPG


fully shaved engine bay , note missing stock e9 radiator bracket

002.JPG


headers installed, and modified euro s38 b38 air horns installed ,, note the severe angle we had to tilt the engine to slide it in

005.JPG


how many monkeys does it take to slide an engine in ? hahaha

015.JPG


sitting back in place , nice view of modded euro air horns

016.JPG


view of headers tight fit

017.JPG


got a junk e28 M5 radiator to use for mock up, Ill be getting an aluminum version of this , had to cut out the stock mounts , and drill some holes to mount the different style Radiator , next Ill need to start routing the coolant hoses .

008.JPG


before we started on the cage we cut out the sunroof Frame , when the cage was complete Frank welded the sunroof back in place , Today We filled in the gap where the sunroof seal was with epoxy . when it goes to the body shop they will skim it with filler and no one will know it ever had a roof !

002.JPG


Im not a fan of the stock shifter assemblies , I like a solid mounted deal . however I find some of the sperical bearing ones are just tooo notchy . so I cut out the cup of an aluminum shifter tower ( as seen above) and had it welded to a plate that I shape and mount solidly to the body for a very nice precise shift , , the rod is been cut to size and I use a Z3 shift rod , Ill probably use a different knob .

013.JPG



Ill have few more things to finish that project up but mocked up for now and feels great !

Looking great B.

I did a similar thing. I put the head back on the M5 and should have dropped the headers down next to the block and then they could be pulled up and mounted. Now I have to remove the studs and still not sure the headers will make it back in:x May require some loose engine mounts and serious tilting.

Are those the plastic air horns from the B38. Are the M88 euro horns different than S38?

My Wizard radiator is out right now. Is that what you're getting?
You can borrow mine if you want to check a fit?

This next entry will make some of you collectors upset , and faint of heart ! We hacked up a perfectly good set of doors . One to make room for the roll cage bars , and two to get rid of the weight . Don't know how many of you have had the doors off , let me tell you, the Damn things are heavy . with out glass l and window motor/ regulator assembly they weigh about 48 pounds ! My friend Ken took the scapel and liposuctioned them down to about 20 pounds , thus saving 56 pounds ! He cut the frames down to basicly the door skins, cut out the safety bar, used a hole saw to cut some holes in structurally needed pieces , then did a beautiful jog gutting the hinges .

Just for interest, approx. weights:

A frame + glass - 3.75kg
Door internals (elec windows) - 8kg
Door main window glass - 4.5kg
Carcass minus outer skin - 8.25kg (not CSL with aluminium inner panel)
Steel outer skin - 5.75kg

approx. total 31kg - excludes sound deadening on inside and hinges

aluminium door skin approx. 2kg
4x steel door hinges approx. 5kg
4x aluminium door hinges approx. 1.75kg

Admire the effort. Aluminium skins?

I found that you could place a £/$ per kg value on weight...the aluminium bonnet and bootlid in particular did not fair well. Aluminium hinges and door skins were coming in at about £60-70 per kg saved.

I have an aluminium bootlid but also stripped the steel bootlid to the frame and will cover with an aluminium

Bootlid outer skin - approx. 8.25kg, frame 6.75kg. You could save maybe 3kg out of the bootlid with aluminium skin and a few additional holes - unless you are going GRP?

Amazing degree of detail (and work)! I like the "Polaris Coupe" in the background too! Glad this is all on one thread, will make it much easier to follow and use for a reference. Thanks!

To lose the weight and keep the original metal for some other day, have a look at http://mrglasscars.com - BMW - Section 6.

I've always wondered what his components are like 'cause if you went the full replacement route at race weight it would add up to 319lbs saved for $3000. Then you could sell the real metal parts for.... I don't really know but it probably wouldn't cover what it would cost to make it look "right"

Still.....

Funny you mention that < I actually have Mr. Glasscars hood and deck lid . There not bad , they will require a bit of tweeking to get right , But I will say he was very easy to deal with , very quick , etc, etc . The doors wouldn't have worked , the driver side bars pretude preety far out into the door so I cut away .

custom decklid with intergrated " lip spoiler"

race weight hood

note the two year layer of dirt , I dragged them out of the attic to photo for you guys today .

we also got some more stuff done before she goes to the body shop, the window net got installed , we used rodends on the rods like the pro cars do, so that the net goes up and down easier . the fuel cell frame got put in, a huge deal ! we got the dash mounted , and I made the oil lines mounted the cooler and remote oil filter , it was big day

you may remember a few weeks ago I cut out the trunk , and now it has a frame for the fuel cell

Any of you guys who have raced cars know what a pain latching the window net is , fumbling around with the damn thing trying to make grid can be stressful . So this is one thing I wanted to make work better, so I stole an idea from the "pro's" .Ken and I put rod ends on the end of the rods going though the net and attached them to the b pilar tube . then welded a safety belt latch in the a pilar corner and in conjunction with the bearings allows super easy movement of the whole thing !

a nice touch to keep the strap in place
