Emma Watson and 2 E34's (Low Mount Turbo M50 Project)

[Dj Buttchug]

Intake side done. Not much other progress other than waiting for a self-centering shifter to come in. 5/10 progress on little things.

IAT temps were a little bit high due to my extravagant piping design to put the air intake in the factory location. Several hours of wasted fabrication time. Intake filter is now on the passenger side of the engine bay. Here is the end result after a few hours and some aluminum sheet.

All systems working now for the first time in over a year.

Weekend shenanigans begin with small tasks like this IC mist switch. Fun.

Nice work on the exhaust, I hear you on that drone.... PM sent.

also, throwing stars are the best

[Dj Buttchug]

Finished the exhaust last weekend. Stock resonator and muffler were starting to piss me off. Vibrant ultra quiet resonator to SuperSprint muffler. Tricky to make a good 2 to 1 collector but managed to get it clean. Still need to add one last hanger using the stock locations on the rear subframe and adjust the Vband clamps. Exhaust has nice low tone but still sounds pretty quiet. Hoping it will be nice for daily driving.

Throwing stars finally refinished and on the car. Fitting nicely with stock M5 tire sizes 235s up front and 255s rear. Tinkering around with the offset I am finding that a 5mm spacer up front and 3mm in the rear should be ok. The M systems will fit over the new front brakes without any spacers which is nice however we run into the tire rubbing against the coilovers up front. As of now we have about 5-7mm of clearance so we will see how that favors when driving.

Not much else going on now as I have been waiting for parts to arrive for the shift linkage I am working on. After some further deliberation I have also decided to make some changes to the center exhaust section and remove the stock resonator. Originally, I had planned to keep it to make sure the exhaust stays quiet, and I do not have any drone. I hate drone, especially in a daily driven car. Problem is the stock resonator is so restrictive that I believe it to be causing issues with turbo spool. The turbo will build boost, but it does it slowly and won't make more than 10psi even with the boost controller adjusted. The wastegate spring is 8lbs so I should be able to make 16 psi with the current setup. I ordered a vibrant ultra quite 2.5 in/out resonator and stainless mandrel bends to fabricate a custom mid-section that will fit my SuperSprint muffler. Hoping to get that project going here as soon as parts arrive.

More to come.

Brake update:

A lovely sparkle purple/plum because dj buttchug.







Brembo decals to finish off. Rear calipers are painted to match.

Managed to finally finish the Intercooler mist system this weekend. Here's a few pics of the hardware and install. $16 amazon pump works surprisingly well and has adjustable PSI range from about 70 to 130. Plenty good to operate misters. 9 mist valves installed in my setup. After hours of deliberation on where and how to install these I ended up using stainless wire tie. Zip ties were no good. The wire is strong and holds the valves steady. I may come up with a different idea later but as of now this is decent.






I set it all up on a small momentary switch and integrated it into a knockoff OEM knob for testing. I wanted to be able to turn things on without taking my hands off the controls and having to reach for a random switch location. The switch has great response and its easily reachable with my thumb in normal driving position. Should be pretty slick once I mold and smooth it in. Due to the depth of the switch I may have to bevel the shifter arm out some... Not quite to this point yet but soon.

More bits rolling in. The mail man hates me.

This is some great work. Makes me miss my E34 530iT quite a bit. E34s deserve more love, these days.

Started working on a distilled/alcohol water misting setup for the Intercooler while I am waiting for other parts. Always wanted to do one but never got around to it on my e30. The Volvo cooler is very large (bigger than the radiator) but relatively thin. I have a pump and some hardware on order to do a clean install. There will be a small contact switch integrated into the shift knob for manual control and I may have the Link control this based off boost pressure. I like the idea of manual control without having to move my hands off normal positions to cycle it on. Ill use a momentary switch to mist the intercooler before (or during hard pulls) Here is the Ebay tank for $29 mounted in the trunk for easy access. It should hold about 1.5L. We will see how much I have to refill it. The pump will be mounted further up in the trunk and the feed line will go on the drivers side inside rocker up into the engine bay.

More updates to come.

The best way I found to dial the knock control in is with some "det cans" and the lightest wastegate spring you have (or no spring at all). If you try, you can induce detonation even at moderate load, and tune the thresholds with that. I have done it before by just progressively adding timing in the 90kPa range while right seat tuning but it wasn't a frequent task because it's quite rare that people have knock control set up in their aftermarket ECUs. My plan was to do so with a quarter tank or so of 87 and a bunch of extra advance. My old det can setup with the harbor freight sound amplifier is busted though so I need to make some new ones.

The style 21s are going to look good on your car especially with the brake upgrade. That's something that interests me but I have no budget for it right now since my block is headed out for a bit. I'm glad to hear you ditched the screamer pipe. Yes, they do sound like garbage, and M5Xs do not sound good at all anyway uncorked, especially without equal length headers. Screamer pipes also make it harder to hear detonation so I eventually stopped tuning cars that had them back when I was a tuner.

Agreed. I paid way more than I wanted to for this set of wheels. Insane how expensive they are now compared to 5 years ago. I have been working on the knock control feature in the Link ECU. I do believe I have some slight detonation right around 8-9 psi but my knock control has been turned off. This will be the first time I've tuned an engine with this feature. My ignition table is no where near dialed in yet. Pulling some time away will be the first step once I get trans back in the car... Always something...
