Any reason you went with urethane for the lcabs over installing e31 monoball lowers?

Like these? : http://cgi.ebay.com/ebaymotors/ws/eBayI ... K:MEWAX:IT

I've had the Grunts sitting in a box for a few years after having purchased them on eBay for $35 shipped. Had them posted here in a FS thread for a month with no interest. If they fall apart I'll go with spherical bearings in the LCA's.

That's terrible! It would be my worse nightmare to get a major build completed only to have the motor fail in <500 miles.
Mike, from the pictures it looks like they did a good job on yours, restrictors appear to be correct size (.109 and change). If you want to purchase a cheap dial bore gauge and a 3 to 4 micrometer I will walk you through the measuring process.

Paul

...continued from Todd's thread regarding issues with his freshly built motor at less than 500 miles likely caused by improperly bored cylinders:

Would the cheap measuring tools at Harbor Freight work? Looked around at the local auto parts store and didn't find anything that seemed like it would be any more accurate than my Blue Point digital calipers. I measured the bore diameter and came up with 92.35 mm. The spec sheet with the pistons calls for 92.5 mm. I'll be taking the motor back to the machine shop for balancing of the rotating assembly. Should I have the bores opened some more? Note I only measured the bores at the tops and not throughout the bore. eBay perhaps?

Calipers are not the right tool for the job. You should grab the bore gauge as suggested.

Motor painted BMW Motorsport Warm Red:

Cool colour.

My block is painted red.

Corner Carver · Post by **Corner Carver** » Apr 11, 2011 10:52 PM

I like it!

Actually, I am surprised how much I do like it

The red really brings out the nuances of the block, much more than black does

Thanks Mike...... now there is a red block in my future

Murfinator, I like that red block!

Which paint did you use on it?

Which paint did you use on it?

I did some research into the Pantone/RAL colors which correspond most closely with the BMW Motorsport colors. Warm Red is the Pantone color which is the closest match. My local finishing shop has my notes with the actual numbers. I purchased two pint cans of Rennsport ROT (stock # 107409) by Uno. Since they mixed it for me I cannot return the second pint can that I have no need for. The local machine shop who frequently paint engine blocks recommended this brand for its excellent heat and oil resistance. I mixed it with the recommended proportions of reducer and hardener and sprayed it through an air gun. Two medium coats provided excellent coverage with only a couple sags due to the uneven surface. Overall I'm pleased with the result.

If you're interested in the extra pint of paint let me know.

Dynaliner installed to replace the crumbling sound deadening material on the firewall.
Heater valve rebuilt
Dogleg 'Sport' transmission resealed, surface corrosion removed, filled with Redline MTL, hardware replaced, new crossmember powdercoated, IE urethane mount and AutoSolutions SSK installed
E34 M5 3.8 guibo and new/longer hardware (search Duke's old posts for reasoning)
BMP brass clutch pivot pin installed
New reverse switch
UUC steel braided slave to master cylinder hose
New direction with the intake: no more restrictive B35 cork. Paul B. sourced a nice S38B36 throttle assembly and made some adapter plates for mounting to the B35 head he's putting the finishing touches on (all new valvetrain, custom cam, etc).
Picked up an S38B35 air accumulator to use as a mock up for a custom aluminum air accumulator to more efficiently plumb in the output from the TCD S3 water-air intercooler
Ceramic coating on all heat shields (+ NOS Hartge passenger shock pillar to firewall brake line heat shield), exhaust (3" TCD) and oil pan
TIG'd an AN -10 bung on the oil pan for turbo oil return line
Landed an authentic Hartge handbrake handle
Received a black suede shift boot with Motorsport stitching from Shift Style to match the seats and steering wheel
New trunk gasket
Removed one-piece hood liner and foam
Installed BMP 3-piece hood liner
Sold the M-Systems wheels to a good home in SD
Deal fell through on the BBS 16's
Went with a nice set of Hartge Design C 17" wheels found here on the board (since first seeing them August 2009 in Monterey on RonP's stunning H5S which took first to my second in the concours, I've been in love with them. The decision was a no-brainer since the car was already sporting Hartge plasticware: airdam, side skirts and rear valance)..in the process of being refinished.

There's probably more, but rest assured I haven't lost interest in the project. Thanks for the interest. Pics soon...

Very interesting. I was looking into doing almost the same to my 86 528e but using the block of a 98 528i paired to the 88 heads before boosting it. I'll post pictures of my car which already went through several upgrades from M5 kit,suspensions, swaybars, brakes. It just need to go fast

I'm aching for an update!

Murfinator · Post by **Murfinator** » Jul 02, 2011 4:05 PM

Haven't taken many pics lately but they are forthcoming. Paul still has the head and throttle assembly. Every time we speak he describes more work he's done tinkering to make it perform better. If he keeps it another year I'll be able to launch the space shuttle with that sucker.

Debating whether to sell the 17" Hartge Design C wheels I've begun refinishing and replacing them with the 18" Design C's Luke is selling on the board. I'm actually liking the look of the 18's less and for the cost of shipping from Poland it may not be worth the trouble.

I've been in contract with Jon A. regarding brake setups. I'll be removing and selling the 750 calipers, vented rotors and stainless lines. Replacing them will be Alcon calipers and 12# motorsport rotors mounted to his custom aluminum rotor hats. The entire setup will be about half the weight of my current setup with great performance. Looking forward to diving deeper into those corners.

I've assembled the oil level sensor (new) and replaced all the hardware with new.
New hardware for the block: bolts, studs, gaskets, water pump and the aforementioned items such as MM oil pump.

I've been laying sod as well as building and shooting a couple of custom rifles lately so the bulk of my time has been spent in other endeavors. However, progress is being made and I am enjoying the journey.

Dogleg: cleaned, fresh fluids, new hardware, AutoSolutions SSK, new sheetmetal console and rubber, new E34 M5 guibo and hardware, Racing Dynamics shift knob to go with the pedals.

Started smoothing out a few dings on the oil pan and ended up with this: new oil level sensor and hardware, magnetic drain plug, TIG'd -10 AN fitting for turbo oil return and ceramic coating (same as exhaust and heat shields). Capped the M106 drain on the block and opted for a lower entry point. It's angled back for a straighter shot from the turbo.

Current status of the car:

My wife is refinishing some antique chairs.

Where there is a Dremel there is a way: good-bye stock airbox and coil bracket.

I'm going to miss the stock airbox and coil bracket.

Not me, but I can ship them to you FedEx Ground.

I don't care for most of what came stock.

itsbrokeagain: The remaining pint of engine paint sold a while ago.

The dogleg is pretty weak. You will kill the layshaft bearing in short order.

The oil return fitting should be 90 degrees.

Why, so it has a sharper bend to make on its way back into the oil pan? The dogleg is weak because if I drop the clutch at 6k from a stop then I could twist the input shaft off (if I can find a clutch that will hold and be tractable)?

Please back up your statements. I'm open to suggestions. Thanks
