First of all, thanks to Jrrrrrrr for his control arm DIY writeup found here:

http://www.m3forum.net/m3forum/showthread.php?t=402063

Got to the control arms with the new ball joints and tie rods.







All ball joints out, put in all new ones for only $56.94





Also went and replaced the tie rods which was really easy





And as a last touch I made a secured storage bin for road trips and general storage as without an interior there's nowhere to put things lol simply drilled 4 holes and zip tied it to existing holes in the trunk.





And with that the trunk is packed with oil, coolant, and tools for the road trip to MPact Hoping for the best but again this is its longest trip ever so prepped for anything.

Planning to do an oil change while you are out there?

Lol only if I have to, its been burning a bit of oil lately, and developed a valve cover leak so I'm bringing plenty in case it gets worse. And the black jugs are actually full of coolant.

So finally getting to engine work with a 3.5" Intake and M50 Manifold swap. I did not like the fact that there was no consensus on whether a 3.5" intake and big bore throttle body actually increased power or did anything, with repeated dyno runs from multiple people showing 0-2whp gains. And with the Samco elbow, Porsche MAF, and aftermarket intake running almost $1000 all together I wasn't gonna waste the money if I didn't have to so I made my own for about $80.

Started with a 3.5" exhaust tube, 3.5" is hard to find so I had to order a 4 ft section.


Disassembled the stock MAF and a junk China one I already had lying around. I removed the element from the stock one and cut out the mounting deck from the China one, smoothing it to fit the 3.5" profile.



Cut the hole for the MAF and bolted the deck down with little bolts and some gasket maker to make a seal.







Drilled a hole in this tube for a nipple for the ICV as I didn't want to damage my silicone boot or risk whatever I did falling out of the boot. MIG welded it on and finished the seal with JB Weld. Finished product is a 3.5" MAF for around $45 that doesn't require a retune like the Porsche one. I know the Porsche reads quicker and logs more data, but at $500 with possibly no gains, I'll pass.



Ordered local at Mandrel Bend in Glen Burnie a 3.5" silicone elbow. Would've got black but they were out of stock. Cut to fit and used adaptors to get it to seal with the now relatively tiny throttle body inlet.





Engine noise is definitely more pronounced than before and for only $80 I'm real happy with it. Coupled with my $50 intake makes a full DIY 3.5" intake for only about $20 more than just the premade Samco throttle body boot.





Currently cleaning M50 and awaiting Eric's kit from M50manifold.com

Are you going to tune for the larger MAF housing? People typically upgrade the MAF sensor when going with larger housings. Any concerns about the stock sensor maxing out?

From all my readings on BBTBs, larger MAFs, and intakes, the stock MAF should be OK. I did think about that but for now I'm rolling with it. It ran like absolute crap also refusing to start sometimes at first but after about 5 min the idle smoothed right out. Maybe my imagination but maybe even smoother than stock. I'll get a proper tune when I get my cams in over the winter but for now everything seems fine.

M50 swap done! I don't really feel the loss of low end torque some people did, maybe just a little. Past 4k it definitely feels quicker and the 6-7k range feels like it pulls harder. Eric's kit is solid with good instructions, car fired up and found its smooth idle after about 2-3 starts.





Chokey chokey



Even after getting a bit more tipsy over the course of the day than planned the instructions were still spot on and easy to understand.





That's gonna be it for this build until after H20i in October, driving the car there then pulling the motor out when I get back for the winter. A ring somewhere is shot, if I get on it repeatedly the car comes up missing a quart or 2 of oil. Only replacing what I feel necessary trying to stay in my budget and for future F/I goals.

Parts List:
JE Pistons Stock Compression (re-using OE S52 forged rods)
VAC High Pressure Springs
Riot Racing Regrind Cams
ARP Headstuds
New Crank Bearings
OE Headgasket and various other gaskets
Polished Head Runners

Out of curiosity, what ECU tune is in the car now that lets it rev to 7500?
