Welll its not your build Duke. Looks like its coming along beautifully OP.

The fuel rail is a custom piece from Imagineering nearly identical to the the ones in Lucifer's Hammer though I'll only be running a single rail with 65# injectors: 91 octane street / 111 track. Ken and Moose were sharp enough to foresee issues I'd have with E85. Shouldn't need it anyhow.

Duke: I had considered taking Paul up on his offer to build a custom fuel cell but didn't feel like waiting ~3 years for it to be finished.

Decided to put the MIG to use and build a custom baffle to go with the recently released Aeromotive A1000 stealth mount pump option. The baffle box extends through the bottom of the stock fuel tank ~1/4" with the pickup and integral 100 micron filter centered in the low spot in the center/rear of the tank. Note the -6 AN return where the lift pump ports once were.

Also didn't want to give up trunk space that will be needed for luggage during road trips. That was also the justification for the sub enclosure under the rear seat and the amplifiers mounted to the trunk bulkhead, keep the trunk useful.

Roth USA HD pedal bracket reinforcement went in as easy as pie. The bracket had already been reinforced prior to 5-speed swap several years ago via a few weld beads along the weak areas.
I don't believe I'll have a problem now. Kudos to David Pepin for engineering a simple yet elegant solution to this malady in our cars.

B35 cylinder head -> B36 ITB adapter plates installed.

B36 ITB trumpets installed.

S38B35 E28 accumulator fitted with 4-ply silicone reducers.
Each reducer was trimmed 14mm on the throttle side to bring the trumpets further inside the accumulator, creating a smooth transition from the accumulator walls to each trumpet mouth.

Real nice work.

Are you making these adaptors by your self, if so can I buy from you.
I have S38B36 runners going on to an 3453cc M90.

Build update:

GOLDEN MONKEY ALERT...GOLDEN MONKEY ALERT...GOLDEN MONKEY ALERT!!!

Currently resting safely atop the motor.

Been looking for one of these babies for years. Why Hartge? Because of all the other Hartge crap on the car. I really couldn't care less that it's not an 'original' Hartge car. It's mine and I like it.

-Engine management system - MS perhaps? No way. My local tuning shop, Turbo Lab, happens to be AEM certified. Took a look through the AEM literature regarding their new Infinity EMS. Impressive to say the least: http://www.aemelectronics.com/engine-ma ... d9823hsod5

-Modify S38/B35 air accumulator: in work plugging several hose ports I won't be needing (VC vent, etc..). Trying to figure out what color to powder coat this thing. May go the Korman route of white with ///M stripes on the top like Ken's LH build. It just looks NICE.

-Flywheel/clutch - Spec stage 3+ on the shelf waiting for the engine to be installed

-Finish building center console gauge pod with: boost, AFR and EGT or intake charge temp gauges. If I go with the AEM EMS I'll use their new multi-gauge setup with three gauges daisychained and able to monitor 19 channels simultaneously: http://www.aemelectronics.com/gauges-26 ... -gauge-33/

-Front calipers/rotors - Alcon 4-piston with 12# 348 x 30mm Alcon rotors attached with the custom lightweight T-6061 aluminum and anodized black rotor hats purchased from Jon. This BBK has been in various stages of production at UUC since January.

-High flow fuel pump installed in tank with larger diameter lines. Pump installed and tank fitted. Had to drop it 1.5" and still have a clearance issue with the 90deg fitting on the top of the pump. Also need to reassess the muffler since the top is now resting on the heatshield which attaches to the side of the fuel tank. Will likely go with a smaller diameter, round vs. oval muffler. Turbo cars already have the 'spinning' muffler so although its a 3" straight-thru exhaust the noise shouldn't been too obnoxious with a smaller muffler. -8 feed & -6 braided PTFE lines ran from engine bay to fuel tank.

-Mount Aeromotive 40 micron fuel filter & fuel pump controller: in work

-Swap electric seat center console with manual: DONE

-Weld in 524 battery tray - using TD washer tank: DONE and washer lines rerouted. Using an E34 pump, brass fittings and new lines. The location, which is a bit higher and forward of the drivers front wheel is not ideal but I already have a second battery in the right-rear M5 OE location which feeds the audio system. Corner balancing found this arrangement to be suitable. Going to have to get tricky with the charge piping...

-Assemble Hartge Design C 17 x 8.5 & 17 x 9.5 wheels: DONE. All wheels assembled and new Continental Extreme Contact DW's mounted: 225-45's and 275-40's. The rear M-Tech flares may need to go and more extreme fender rolling performed. If needed I have a grinder and MIG if we need to go there. They will fit. I will need all that rubber and more.

-Larger aluminum radiator: Griffin - http://www.griffinrad.com/

-A>A intercooler: removed OE oil cooler to make space. Will likely go with a remote mount oil filter and custom cooler mounted elsewhere. Nice filter head, newish hoses ($$) and heat exchanger up for sale.

-Fabricate tubular top-mount exhaust manifold: watching Otis' E30 build updates. Most likely will use the same flange, 321 stainless 1 3/8" ID primaries, dual wastegates, divided T4 flange to .7 to .8 split exhaust housing (tuning will tell).

-Determine proper size of turbo: received some good input here from owners/builder of similarly equipped cars. Looking at either a GT4088R or 6765 (aka T04Z or T67). "63 trim" compressor wheel. 67mm inducer, 84mm exducer.

-B36 ITB's: installed Moose's linkage fix. Very nice. Disassembled and sourced all hardware not NLA. Polished & clearcoated throttle housings. Lots of masking. Removed unneeded vacuum ports and welded smooth.

-Alternator Swap: current 140a E32/4 alternator vent hose doesn't fit with the S38 accumulator/plenum. Looking at a rebuilt 150a unit. The existing 140a alternator will be up for sale.

-Looking for M5 injector harness loom tray. I believe it's part of the engine wiring harness. Can't find a diagram or part number for the housing itself: aluminum tray for wires/plugs and plastic housing cover. Any leads would be greatly appreciated.

Dude. Your just being a tease without pics of the valve cover on the engine.

Did they give you a price on that Infinity EMS?

I know. It really completes the look of the motor perfectly. Want to get the ITB's cleaned up before posting pics. Ideally I'd have the exhaust manifold and turbo on there too...but not yet.

M. Holtmeier wrote:Did they give you a price on that Infinity EMS?

A couple of AEM's release video's mention a price of <$2,000 + options (custom harness, tuning extras, etc..). Their website has not been updated yet with specific pricing. The cost is roughly equivalent to Electromotive's Tec-3R and Haltech's Platinum 2000. Between the options, support and dependability I'm more than willing to pay in the neighborhood of this amount. Besides, my time is valuable and I'm certainly a novice when it comes to tuning so the balance sheet will likely remain in the black vs. building my own MS setup. Judging from all the builds I've seen using MS I don't have a warm&fuzzy that system will meet my needs or even work properly without a significant investment of my time and others (dyno time=$$$$). I really don't need the frustration.

I remember the first photo of the red block, and now looking at it engine, I'm drooling! fantastic!

Mike,

Nice valve cover! That is going to look sweet on your motor.

Murfinator · Post by **Murfinator** » Jul 29, 2012 6:46 PM

A few quick shots last night after partial refurbishment of the throttles: Dremel & wire brush, Alumablast and high-temp clear with new hardware.
The plenum is in work and the alternator found a new home (sold). Other options being explored.

Please pardon the image quality.

So what are you doing about the t-stat?

Murfinator · Post by **Murfinator** » Jul 30, 2012 1:12 AM

mooseheadm5 wrote:So what are you doing about the t-stat?

More modification since the rear port contacts the #1 TB.

Post by **mooseheadm5** » Jul 30, 2012 1:34 PM

I knew that was going to be an issue, but I haven't ever seen what anyone has done about it. Have you had someone address this yet or no? Just curious.

This is the tray for the injectors harnes, you can use the one from a m30b34/35 as they will fit 100%

Nice uppdate

I believe you're confusing the B35 injector harness for the M5. The B34 didn't have a piece of this nature, only wrapped wires and plugs. Below is a photo depicting a B35 harness cover which is noticeably larger than the M5 piece pictured above (~3x wider). Note the ITB throttle linkage had to be reversed to the bottom from the top since it would contact the B35 harness cover if left in its original position. Notice the accelerator bowden cable mount bent 90 degrees down.

Also note the t-stat assembly which has been modified for use of a B34/35 cylinder head with the ITB's.

That reminds me. I need to go to the shed tonight and see if I have that cover for you.

Yes please. Any help sourcing these parts (fuel injector harness tray & cover) would be greatly appreciated.

Post by **mooseheadm5** » Aug 01, 2012 10:01 PM

Just searched the shed. Only one of the two harnesses I could find in my storage area had the cover on it. If the one on my car has it (I honestly can't remember) then we'll talk about this one. You want just the cover or the whole harness? I'm concerned about breaking the thing taking it off.
