Jon, I'd aim for 0.003" or less runout. Searching my memory banks I seem to remember anything greater than that being noticeable under braking.

Hold on Tony.... what were you using the socks for? Or maybe a better question, did you use the socks again after filtering the tainted gas?

Happy birthday man, hope you are having a good one! I'm surprised to hear you're 50, I would have guessed 48 or so.

It's not tiny. Somewhat smaller than a can of chunky soup, but not as small as chicken noodle.

e30 BMW. Good size, cheap, metal case.

Well, I'll let the photos speak for what I've been up to lately... 24' x 16' with 10' ceilings. It's not huge, but it will do for now.

I've also noticed "Too Intense Restorations" carries similar panels. Just working on some interior plans for my own car...

Wow... I fail to see the effect on bumpsteer. Absolutely untrue in my experience; I've had a urethane couple installed in my Z for about 8 years, and daily drove it for 3 of those years. I wouldn't hesitate to do it again as it made significant improvements to steering feel without introducing much in the way of harshness or vibration. For what it's worth, in British Columbia it's not legal to weld steering components like you've done. I am sure they are trying to protect people from themselves with this type of law, but I would also suspect there is an ounce of history and truth behind the reasons for the law. What I take from that is "be damn sure" your welds are good.

Surprised to find this, but take a look: http://qualitycarinterior.com/view-by-car-datsun-240z.html Dash caps, carpet kits, and interior plastic for 240z... In any colour you choose. I hope this helps someone out!

I checked a while ago and MSA wasn't prepared to tell me when they'd have stock, if ever.

I beg to differ! Carb cleaner hurts more!

Sweet!

Is there an option of an RPM pickup that isn't inductive? On the DD machine I used to have we would just use the tach signal wire.

Awesome Terry. Though your car doesn't look much like a Z car anymore, I must say that it is one of the best executions of a custom body that I have ever seen. You have a talent for design!

I think you'll be surprised at the difference a turbo makes to the tone. I respectfully disagree with your last statement. However, I have nothing to prove me right or you wrong at this point. (or vice-versa!)

Fair comments, I guess I need to find some more video/sound clips of L-series turbo headers... anyone have some to share?

Yes I am using them. They took me 1 day to receive after ordering. The car would go as low as I wanted it to, because I installed the perch the sleeve mounts on...

I think I could accomplish the transition from 2.5" to dual 2.25" similar to above but without the cone if I cut the merge portion back far enough and ovalled the tube on the 2.25" end slightly. Does anyone have information on the direct comparison of sound reduction between a 3" straight through muffler with a small diameter case, and the same 2.25" straight through muffler with the same case? If it sounds like a camaro after all this, I'm setting the car on fire. Seriously, that isn't at all what I am trying to accomplish here, see the videos in the first post...

Food grade is super easy to work with because the bends are so darn good, but point taken on wall thickness. I will order material to make this system anyway, so i can spec whatever. Food grade is avaialble in the 0.049" area though. TIG welding and backpurging are a given. John, if the food grade stuff is 304, does it really have a significantly different carbon content than other 304SS? The system will use V-Band connections to make removal/installation a snap. I will look around a little for collectors, but I think i can probably make what I need better and cheaper than the alternatives, while keeping the angles to a minimum. Something like this looks like it would work well from the 2.5" downpipe to the resonator box.

Construction of this system will be entirely food grade stainless steel, similar to this:

I'm going to ask about the ultimate exhaust system, even though the site rules clearly state that there isn't one. I hope I can sneak this thread past the moderators. One of the things that came out of my recent L6 turbo engine build, is that I really don't like the sound of my exhaust. This was once a track only car, and now it's going to get more street duty, so a change needs to be made to quiet it down. At the same time, I am planning on going full stainless and building the last exhaust this car will ever need. Right now the car sounds like a glorified motorboat. (or Subaru) The current exhaust comes out of the turbo into a 2.5" mandrel bent downpipe, transitions to 3" and runs through a 3" round magnaflow (straight through) muffler. I've got about a 6" long tip on the muffler to route gases away from the rear of the car. It's loud, it's raw, it's fine for the car as a race car. Video with current exhaust sound: As a street car, I want to achieve something a little more exotic sounding, as well as quieter. For example: I believe in order to achieve the sound I want, I am going to need to run dual functional tail pipes. I think running a different length to each side will create the harmonized sound I am looking for. In my mind the system plays out like this: 2.5" mandrel bent downpipe off of the turbo Custom SS "Y" from 2.5" to dual 2.25" Dual 2.25" each into a 12" long resonator box in the tranny tunnel One 2.25" pipe exits at the outside face of the box One 2.25" pipe exits 8" into the box, making this path a different length than the other [*]2.25" pipe runs to the back of the car, one exit on each side, each through a muffler. [*]Dual tip exits from each muffler. My rationale is that the staggered exit from the resonator box will allow the same pulse to split and reach the tailpipes at different times, therefore smoothing out the exhaust note to a degree. By running 2 larger mufflers (than the current 1 smallish muffler) I should be able to control the volume a bit better. The dual tips are more for show, but if I can stagger the paths between the muffler and each of it's tips, more smoothness should ensue. Dual 2.25" is effectively larger than the 3" single I have now, and probably easier to package under the car as well. I might be way off base with these assumptions, but I welcome any input those with experience on exhaust tuning or exhaust design may be willing to share.

Wow, that's a lot of time!

#1 for sure.

Update: 1 dead injector = poor idle. Much better now with a new injector installed. Still roughly -15 to -16 in/hg at idle though...

Well congratulations, you did it again.
