Audio Tuning! Setting my gains!

So my sub blew AGAIN. It’s the third one in 3 years. So I analyzed every area of my system and I figured out instead of giving it about 300 Watts I was pushing closer to 450 to the sub and over time it just blew the voice coils. So I ordered another Alpine Type R subwoofer and before I installed it I meticulously set the gains again. In case you’re u are not familiar setting the gains will allow you to adjust the amplifier input voltage to match the head units output voltage. If this isn’t done correctly you can distort the amps input stage and the amplify the distorted signal which can send some bad stuff to the speakers not to mention just plain sound bad. The problem I had was I set the test tones with an iPhone that may have had a set output level. I then got a new iPhone and a new output adapter that had a variable output. I set the gains at about 3/4 the output volume on the phone. That’s great as long as I don’t run the iphone output hotter than 75% of the max volume. Which I’m sure there were times it was maxed out. This was sending 25% more voltage to the inputs of the amp and them amplified...poof. Speaker blown.

So my solution was to set the gains at 100% volume level from the phone. I used a test tone app to deliver pure test tones at certain frequencies. I connected a digital multimeter to the amp output and measured the AC voltage. I then turned on loudness as well as the bass up to a +3 on the eq. This is my normal listening setting. I also turned the sub channel up to 10 when before my gain was set when it was on 7. I used these settings to adjust the voltage to send out 300 Watts on those settings. The speaker is rated at 350 Watts RMS and 1000 Watts peak. I also set the front speakers gain at those settings to put out 85 watts. That’s what the amp is rated at even though the speakers can handle 125.

Settings for setting the gains for the mids and tweeters

The results are amazing. I thought it sounded good before but now it’s cleaner and clearer. The low end isn’t muddy like before it’s very defined and punchy. The highs are clear and bright. I actually had to fade the fronts out a bit because they were too bright and it wasn’t balanced. Once I got the balance right it was like butter. Smoooth!


Out With The 4…And In With The 5!!! 5 Speed Swap Underway!

So while driving home from work in traffic, I went to downshift from 4th gear to 3rd and to my shock, the shifter wouldn't budge! The transmission was stuck in 4th gear! Stopped the car and after a lot of effort I got the car into reverse then finally got into 1st. Went through the gears and again when I got to 4th, it got stuck. Luckily I was close to home so I limped the rest of the way on 3 forward gears. Yup this 4 speed has given up. So....

Time for that 5 speed install!

My philosophy on building a restomod is, "Drive it like you stole it and if something breaks, upgrade it!"

Years ago my buddy Le Tran was selling an E21 5 speed out of his personal 2002. I bought it so I could have a good Getrag 245 for that transmission swap. I have also been putting parts together for this job. I had the transmission support bracket, a shortened driveshaft, guibo, clutch slave cylinder and 5 speed speedo cable.

Part 1. Prep and Getting the car to Vintage BMW Racing in Long Beach.

I have been planning on Ken Blasko to do the swap and since this was unexpected I had to wait a few days for him to get a free lift in the shop. He needed access to the transmission tunnel so that meant removing the center console and removing the carpet on the transmission tunnel. Once the center console was gone it was time to clean up the rats nest of wires that are behind the center console.

Wiring Mess going to Center Console


It came time to deliver the car. Kens shop is about 30 miles from me. Should I risk it with 3 forward gears and reverse? What if something else goes? I played it safe. Called AAA for a tow. Since I gave the platinum package or whatever that is I get free towing up to 250 miles. So I loaded up the car with a 5 speed we in the trunk and a driveshaft and various bits in the car and had a flatbed tow it to Long Beach.

Part 2: The delivery

2002 en route to Vintage BMW Racing in Long Beach, Ca.

The trip was uneventful and I followed the tow truck in the Audi. What stood out is that this tow truck driver was able to get the car in and off the truck with zero scraping and without additional boards or ramps even for it being so low. When Ken got it he immediately rolled it onto the lift and began inspecting the parts as well as the car. Transmission was first. While I trust Le, it's been sitting for over 5 years and I think it was sitting a few years before I got it. He examined the input and output shafts and was pleased with them. Initial signs are good on this box! Driveshaft. That also checked out very good. He's gonna replace the center support bearing and have it balanced. Seemed the u joints were in pretty good shape. It's also the exact size needed for a 5 speed conversion. Nice again. The car looked good. The diff is spitting out fluid but we knew that. A rebuilt 3.64 LSD is waiting for me at Le's shop, 2002 Garagewerks. I could use a front wheel bearing and the drivers side motor mount support looks like it's starting develop a hairline crack.  Other than those things, the car is in GREAT shape!!!  Oh and looking at the stance while it was on the flatbed, the front ride height is PERFECT!!


Ride Height Solved? Maybe!!

I have been thinking of building a set of coil over for essentially is 1/2". I wanted the front of the car 1/2" lower. The problem is when I had the front lower something sounded horrible under the front end and it felt like something was grinding. When I lowered the car I used Ireland Engineering Stage 2 springs which lower the car a good amount. I wanted a little bit more so I cut 1/2 coil off the front springs and got a pretty good look but functionally it wasn't good because of the grinding and rubbing. So I put the spacers back on top of the struts and raised it about 1/2" and the ride was great. I asked a number of 02 gurus why there was the grinding noise and they were baffled. Since the spacer is essentially raising the body, it's not really changing the suspension geometry that much and there shouldn't be such a drastic difference. Well that was 6 Year’s ago and now before I do the coil overs, I thought I would try to remove the space and see what was grinding. Well I removed the spacer and guess what...NO GRINDING!!!!!! So I now think I have gotten the car to a ride height I am happy with visually as well as functionally. Whats the difference? Well the wheel and tire combo. When I lowered the car initially I was using 14" BBS wheels from an E30 BMW. They were VERY close to rubbing on the inside and some people need spacers on the front to run them so maybe they were the culprit as now I am running 15" BBS wheels and I am using spacers to push them out exactly where I want them which is as far out as possible, but within the fender. This has probably given me some extra clearance between the tire and the strut.


Gauge Cluster Update

Updated my gauge cluster and wow what a HUGE difference! I was at the SoCal Vintage BMW car show and ran across Bavarian Restoration. They are up north in Richmond but made the trip down south and had a display gauge cluster that they restored. It looked great! It had red needles, the wood grain was removed and the gauge surround area was painted a flat black and the area around the gauges were painted silver and chrome trim rings were inserted as well. They polished the glass and replaced the standard lighting with red LEDs. They also repaired the odometer gears so for the first time since I have owned the car I now have odometer and trip odometer! The results are pretty amazing and are a night and day difference. Here are some pics...


My Tijuana Paintjob: 1 Year Paint Update

Just an update on the car paint  wow it's been just about a year since I got the car back from paint in Tijuana.  I'm very happy with the results still.  Is it perfect?  No, but to get a better paint job probably would have cost 4 times as much.  My only REAL complaint is the headliner and they have agreed to redo that.  It's just coming undone in one corner.  


Here are some pics of the car I just snapped.  Nothing special.


Cracked Header Fixed!

So I took the car to Ken at Vintage BMW racing to look at the header and help me diagnose it. We determined it was the number 4 cylinder tube near mounting plate. So on my next day off I removed the header and took it to the muffler shop that’s been doing the work on the car lately OC Muffler I Costa Mesa.

Here is the crack.

Once it was welded and patched the header went back in a hell of a lot easier than it came out and wham! No more noise!! Excellent result! Cost me about $50 for the repair including a new exhaust manifold gasket.  This is a temporary fix though.  The plan will be to replace the header.  This will probably be the Ireland Engineering Alpina style header which is about $500 plus install and any pipe work that may need to be done by the muffler shop.

Old Car Woes

Nothing new here just part of owning a 41 year old car. It’s just that when it rains it pours lol.

So first I have a rather bad ticking and rattling sound coming from the engine bay. Turns out the sound is a cracked header. So we will see if the answer is to repair or replace.

Then I am experiencing a lot of groans and moans from the transmission. Yup bearings are pretty worn. Replaced the fluid with redline MT90 and it smoothed the shifting considerably but it’s still quite noisy.

Lastly in addition to the transmission noise my leaky diff is making a lot of noise as well. I have topped it off with diff fluid and it got quieter but it’s still leaking and will need to be swapped out.

So time to get some of these things fixed!!


New Gallery…15″ BBS on Fjord Blue BMW 2002

Had the chance to pull out the Nikon D700 and shoot a few pics of the car instead of the normal iPhone pics I normally post.  In addition to this being the first real pics of the car with the new BBS wheels installed, I also did a quick detail with a new product I'm trying out which is the Mothers Quick Detail spray.  I'm VERY impressed with this product.  More on that in another update .  Enjoy the pics!



BBS Rims Installed!!!

Flord Blue BMW 2002 with 15" BBS Rims

Woohoo!!!!  This is a great day.  The loooong project BBS is complete!  The wheels are installed on the car and look great!!  What a process. The one thing that I can say is that I have never seen another 2002 with this wheel on it.  Very custom, yet very classy.  I started the process by finding a great condition set of Mazda RX7 mk II BBS wheels and had them re drilled, lips polished, centers painted, and rare blue BBS center caps ordered from Germany. Then I had longer wheel studs installed, found a bad hub and axle in the process then measured for spacers and decided on 17mm on the rear and 9mm on the front. With the longer wheel studs on the rear the center caps didn't fit, so I had to grind down the plastic around the locking mechanism and that gave me just enough space for the cap to fit.

Rear hub with 17mm spacer on the longer wheel studs.

Front hub with 9mm spacer installed.

Initial impressions.  Feels smooth!  The ONLY thing is the car has lost a bit of oomph.  I think this is due to the smaller overall diameter.  It's not huge, but I noticed.  The car is definitely more responsive and more chuckable. The lighter weight wheels can be felt.  When I get new tires I will go with either 195/55/15 or 205/50/15 to be closer to the stock rolling diameter.  In the meantime, I'm enjoying the look and feel!!  As a kid, I wanted a 2002 with BBS rims. Now I have one!!


April 2017….New list of things to complete! #goals

1976 BMW 2002 in Fjord Blue Bbs

1976 BMW 2002 in Fjord Blue


Things are moving along on the car! The motor rebuild has made driving the car a blast. I am driving around like a menace and I love it!!

Last year I had 3 major things on my list and tons of minor things. The major things were:

  1. Paint and bodywork
  2. Bottom end motor rebuild
  3. 5 speed upgrade

I’m happy to say that numbers 1 and 2 have been completed! Now I have a new list of things to get done in no particular order.

  1. Headliner repair:
    The shop in Mexico replaced the headliner when the paint was done. It was coming unglued in a few spots. I will either take it back to Mexico and have it fixed or get some upholstery contact cement and fix it myself. Leaning toward the latter option.
  2. Front End alignment:
    The front tires are wearing unevenly.  Before I install the new wheels I wanna get an alignment.
  3. Rear wheel studs:
    This will allow me to put spacers on for the 15″ BBS rims. Which brings us to number 3…
  4. BBS 15″ install!
    This has been a 2 year process! Redrill, polished lips, painted centers. Lightweight, 11 pounds a wheel!
  5. Ireland front spoiler:
    I had this painted with the car. It’s just gotta be installed. I have been waiting for the BBS wheels to be installed to do this. I feel the polished lips on the BBS will be a better match to go with the spoiler.
  6. Chrome belt line trim:
    I have the chrome trim in a roll and it’s ready to be installed.
  7. Sunroof Seals:
    I have the rear sunroof seal, just need the front seal and then need to install them.
  8. Re-seat the rear window:
    The rear window needs to be reseated.  Just bought a factory BMW seal to replace the URO seal that popped out.
  9. Bumper rechrome:
    Because the paint came out so good, the bumpers now show their flaws. Having them rechromed will go a loooong way in the overall appearance of the car.
  10. Coco floor mats, pedal pads:
    This literally will finish off the interior. I’m torn over the color of Coco mats to get but I already have the new pedal pads. Just need to put them on. I have a new drivers side floor carpet section so that will be new as well.
  11. Carb adjustment or dual carb install:
    I’m gonna set the float level and see if that fixes the flat spot. If not maybe install a larger fuel needle. If that doesn’t solve the problem maybe it’s time to put those DCOE 40s that are on the shelf.
  12. Engine bay and wiring clean up:
    A lot of wires and ugly stuff in the engine bay. a good engine steam clean as well as cleaning up the wiring and removing extra wires from the smog equipment. The plan is to get the engine bay to match the outside of the car.
  13. Gauge Cluster rebuild:
    My needles shake and my odometer and trip meter do not work. I also want to possibly do a custom color around the gauges where the factory faux wood grain is. I also want to use yellow LEDs for the lights to match the Nakamich radio and VDO gauges.
  14. Custom painted Valve Cover:
    I bought a custom painted valve cover many years ago.  Now it’s starting to show its age. If I clean up the engine bay then the valve cover should be be either repainted or my original one should be painted.  I’m thinking a metallic silver with the BMW M color stripes.
  15. 123/Tune distributor swap:
    I got an advance unit of the Bluetooth distributor. It works amazingly well except when it’s hot it loses the ability to change curves. They say it’s a firmware update that needs to happen to fix that. The problem is I have to remove it and send it back to the Netherlands. I hate to do it because it runs so good!!  I will have to bite the bullet and put my Tii distributor back in and send it back.
  16. Front Bumper Alignment
    I need to get the bumper perfectly aligned.  Its not quite perfect now.  I have 2 options. 1. Try and lower the center section, or 2. Raise the attachment points on the bumper ends.  I may do this after the spoiler is installed just in case that interferes with the bumper end attachment points.

Phew!  Thats a huge list!  lol. Actually the majority of those things are in process and won’t take long to complete.  Stay tuned!!!
