Well, it's been a busy few months, so I haven't made a ton of progress on the Cobra.  My Dad and I did manage to roll it down to the big garage a few weeks ago and I just started work on the brakes.

Here it is sitting in the new garage





I'm installing the ABS from the Mustang into the Cobra, which is going to complicate things quite a bit, but hopefully be worth it.

Here is the pump, I need to find a place to mount it


The factory mount isolates the unit from vibration.  I want to use as much of it as possible




I cut off the horizontal mounting points and welded on a tab to get three bolt holes on roughly the same plane




I decided to mount the unit in the front passenger side of the engine bay.  I made a brace to bolt the mount to.  I will paint the brace and mount gloss black to match the chassis

For most clubs, you should just need the rollbar because it's a convertible.  Depending on the club, you may need some arm restraints if you don't have a hardtop.  You'll want to change all your fluids, including a brake fluid flush (as stated above, DOT4 is the way to go), and make sure the caliper slides are well lubricated.  You could run coolant in your car at all the HPDEs I've ever been to, but everyone has slightly different rules.  When you find a club, just shoot them an email.

Thankfully, Miatas are pretty easy on consumables.  On our LeMons car, we were running the cheapest rear pads with the cheapest rotors all around, only spending some money on front pads - and the brakes tended to last around 50hrs of track time.  At Miata speeds, you really don't need a lot of braking power Smiley  We were running whatever decent decent brake fluid we could get our hands on easily for not too much money (ATE Super Blue/Type 200, Amsoil DOT4, Wilwood EXP600).  We also ran good motor oil (Amsoil Dominator).

This gets me thinking.... I finally decided to spend some money on autocross this year on tires. So I purchased the BFG Rivals, this season so far I estimate I have 30 runs on them. When should I consider shifting them from front to back etc... RWD FRS...

I don't believe the Rivals are directional, right?  If that's the case, I would do like James said and cross rotate them (front left to back right, front right to back left, rear left to front left, rear right to front right) every event.  If you want to do it less frequently, just do it when they start to wear differently.

I'm used to driving a car that only wears the front tires though, so the difference in tire wear after every event is noticeable.

...Know there are a few folks here who may horde some cars...

Pretty sure this is me.  I have a red Miata parts car.  The fender and door are straight, but with faded paint (and a missing mirror).  Come to my house, swap me with your crappy parts and some cash or other item(s) of interest and they can be yours!

This is awesome! Looks like those old CRX's were too cheap. All sold out!


There's one under a tarp in someone's back yard on Huguenot Rd......



I've got one under a trap too if anyone wants a project real cheap like

Even though I know you meant "tarp", "trap" is definitely more appropriate.  This is the kind of trap I always fall for.

where are you located?  i am interested, though not sure i really need a dedicated set of summer tires for my non-autocross car.
57  General / Classifieds / 3.4L Boxster for sale on: May 10, 2015, 06:23:03 PM
Car: 1999 Porsche Boxster w/3.4L and Boxster S parts
Mileage: 75k (body) 87k (motor)
Asking price: $10,000
Contact name: Justin
Email: justin dot loehlein at gmail dot com

Hi all - I'm selling my '99 Boxster that I swapped the 3.4L from a 996 into.  I built the car for my wife after her 996 got totaled last summer, using the motor from that car.  It runs and drives fine around town, but runs lean over 4k rpm at WOT according to my wideband O2 sensor.  The previous owner of the Boxster had it setup for a 3.4, but sold it to me after blowing up two motors.  After much troubleshooting, I suspect the computer does not have the correct tune on it.  I had a local European shop (Perception Motor Werks) look at it and they agreed it's likely the ECU.  Unfortunately, nobody around here tunes these things and I lost all motivation to work on the car since my wife decided she didn't want it.  Anyways, I've got way too many other projects (finishing my garage, Factory Five Cobra, prepping my track day car, restoring my truck, maintaining about 8 more cars), so this one's gotta go.  Details below.

Details of shell
1999 Porsche Boxster
75k miles
Boxster S brakes
Boxster S suspension
Boxster S 3rd radiator
5 speed - shifts great
987 Cayman S exhaust

Donor motor
3.4L from 2000 911
~87k miles
LNE IMS bearing
Motul 8100 X-cess oil since we've had it (~30k miles)
Many new parts while motor was out - AOS, dual mass flywheel, clutch, spark plug tubes, cam seals, water pump, all hoses, belt, power steering lines, etc

I've put ~2k miles on it since completing the swap.  It's fun to drive, but I don't have the time for it.  There are a bunch of door dings, some minor scratches on it, and the passenger corner of the rear bumper is wavy from a small hit in a parking lot.  It'd make an excellent track car once the tune was sorted and wouldn't be too difficult to make it pretty, too!

Here are some photos of the donor motor






And the Boxster (pics from 5/10/15)










You can see the waviness in the rear bumper










You can see a bunch of the door dings and scratches here






The top works great




Interior is clean.  I have the full interior, though the rear carpeting is not in the car to speed up getting to the engine bay








Shoot me an email if you are interested.  I'm happy to answer any questions.

So, I had the last week off of work and my Dad came down to help out on the garage and the car.

We wrapped up the power steering cooler



We also started on the wiring



There is a ton of extra wire that I'll have to clean up



I bent up some pipe to get water to the heater core



It's coming along!



We also put up plywood panels in the workshop portion of the garage and the electrician was able to wrap up his work.  We started moving some stuff down there for storage.  Hopefully this week the aprons get poured and then we can finish spreading stone around the building.



Jeff came over Saturday and gave me a hand welding up this awesome workbench/toolbox using some parts bins that I picked up from a Radio Shack that was closing.  I'm happy with the way that it came out and am making a couple more.
59  General / Autos and Autosport / Re: Factory Five Cobra Build on: March 29, 2015, 05:21:28 PM
Made some more progress.  I pulled the rear end out to get it narrowed 1.5" so that we can keep the ABS.  I also got the motor back in, made the fuel lines, and mounted up a power steering cooler.

PS cooler mounted to some 1" square tube.




The FFR kit comes with an in-tank fuel pickup for an external fuel pump.  I wanted to run an in-tank pump, so I picked up a 320lph pump that came in a pickup with AN fittings welded on.




The fuel supply line is 1/2" and the return is 3/8".  I'm using stainless steel hardline which comes in coils, so I had to straighten them out.




Tube straighteners are ~$300 and basically just some wheels in an adjustable frame.  Folks online have made them, and I had some scrap angle iron laying around, so I ordered some concave wheels and got to work.








The finished product in action.  It works pretty well.  The final result isn't perfectly straight, but I can work with this.






I spent probably a whole day measuring, bending, test-fitting, measuring, removing, bending, test-fitting, etc. over and over again.  I must have removed and installed the lines about 50 times.  I got the 1/2" line finished up first since the 3/8" is a bit easier to work with in case I needed to tweak it to fit next to the 1/2" line.  The end result looks pretty good to me.  I still need to make a few braided hoses to connect the lines to the fuel pump and the pressure regulator, but that should be pretty quick.

The hard lines start at the back of the car.  AN hose will connect them to the fuel pump, running under the panhard rod mount.  I was originally going to run the hard line under the panhard rod mount, but realized that I needed to be able to remove it to get the rear end out.



I used some fancy-pants aluminum clamps to mount the lines to frame.





The lines come through the engine bay on the passenger side footwell.  I mounted the filter there, where it seems like it will be easy to access.  I wish the filter opened up from the other end because then it would have been easier to mount at the rear of the car near the fuel tank where there is plenty of room.




I'll probably wrap up the power steering system next.  Then onto the brakes, which I'll use my tube straightener and bender for again.

And I'm in Mechanicsville, about 10 miles east of RIC airport. I'd be happy to drive the car over there if it ever dries out :-)

Nice, I'll shoot you an email.  Would be good to take a look at your car before I start drilling holes in my Dad's Smiley

Over the past couple weekends, I tackled a couple other projects.  I did manage to run some mig wire along where I'm planning to run the fuel lines.  I tried a couple routes: 1) on the outside of the passenger frame rail and 2) inside the trans tunnel (as recommended by the engine builder!?!?).  I'm definitely going to run the lines on the frame rail, it seems a bunch safer and is not any more complicated.








Once I got that laid out, I pulled the motor back out to put the the steel bellhousing on and attached the transmission, which was way more of a hassle than it should have been because I didn't notice that the clutch alignment tool had a smaller diameter pilot surface than the transmission.  Once I realized why it wasn't lining up, I just used the transmission to line up the clutch.  I also cut some mounting points off the rear of the transmission that interfere with the frame.





61  General / Technical Help / Re: Car scales and corner weight? on: March 05, 2015, 07:41:11 PM
The scale pads are ~2 5/8" tall with a 15"x15" footprint.  I have a set of wood roll-offs for it, but you still need to get the car in place, jack it up, put the roll-offs under the wheels, and position the scales before you can use it.  I like the idea of ramps a lot.  I guess if it was possible to drive over the rear set of ramps and onto the front set, we could crank out a bunch of cars pretty quickly.
62  General / Technical Help / Re: Car scales and corner weight? on: March 04, 2015, 09:12:43 PM
Seems like it would go faster if we just had ramps. Drive your car on, get the weights, get off and go make your adjustments and come back while others are getting their weights. Unless someone has the ability to adjust as it sits, too much time would be spent tweaking and going up and down.

This is a good point.  Maybe someone will build me some ramps Smiley  Hopefully it dries out and warms up soon so I can get the garage wrapped up.
63  General / Autos and Autosport / Re: FSR Summer 2015 Drivers Ed at VIR on: March 04, 2015, 10:15:20 AM
I really want to go, but we're having a family reunion for my Grandmother's birthday that weekend.  I'll have to find another event to go to with you guys!
64  General / Autos and Autosport / Re: Factory Five Cobra Build on: February 27, 2015, 06:00:39 PM
Sweet project. Where you located ?
Ron

I'm out in Powhatan.  You?  I'm actually looking for a point of reference to figure out if I can mount my fuel filter on the firewall.  I think it will depend on how much the body overhangs it, which will determine if the element can be removed from the top when the car is assembled.
65  General / Autos and Autosport / Re: Factory Five Cobra Build on: February 23, 2015, 06:25:26 PM
So, it's been a while.  It's been really cold out and I had a handful of small projects here and there to wrap up, like replacing the coils on my Insight after one died on my way to work.  That's no fun when you don't have garage space.  Thankfully this guy is coming along.  The electric stuff is currently being installed.  After that, I just need to get the final grading done and pour my aprons.  It should be good to go.



We finally got the motor for the Cobra in January, so my Dad made some plans and came down last weekend to get it into the car.  It fits, so now I can start mocking up where to mount all the stuff around it like the fuel pressure regulator, ABS pump, and figure out how I'm going to run the wiring.

The truck driver unloaded the motor onto my trailer in the street and I backed it down the driveway to drag into the garage:


Here it is on the crane:


Then in the car:



We test fitted the headers.  The aluminum part I've got my hand on is the driver's side footbox.  People say it gets really hot and I can see why.  We'll be heat wrapping the headers and I'll be making heat shields for the footboxes.


I had to order some offset dowel pins to position the steel bellhousing correctly, so I'll have to wait for those before I can put the transmission in.  We're also going to use solid motor mounts which we don't have yet, so I'm sure I'll be pulling the motor at least a couple more times.  Thankfully, it's pretty easy when there's no body in the way.
66  General / Open Forum / Re: getting started: minimum requirements? on: February 17, 2015, 05:13:11 AM
Hey there.  Thanks for posting.  I think the banquet may be full, so the club meeting is probably a good place to meet a bunch of folks.  There is one this Thursday, though I'm not sure where.  We usually send out an email ahead of time.  I'd shoot a note to President at vmsc dot org to get added to the email list.

There is a pretty good document on autocross prep in the downloads section.  Look for the document named "Your First Autocross" here.  There is also a link to the SCCA rulebook, though that can be a bit difficult to read through.  The good news is that you don't need a rollbar.  If you do get one, bolt-in is fine.  We also have loaner helmets, though getting your own is a good idea.  If you buy one, make sure to get one that is DOT and SNELL M or SA-rated.

Car-wise, you don't need much to prep.  Make sure your battery is tied down and all your leg nuts are present.  The throttle shouldn't stick and the seat belt needs to work.  Beyond that, there isn't a whole lot of prep required.  When you get to the event, take all the loose stuff out, including your floor mat (so the gas pedal doesn't get caught under it).

When coming to an event, I think the only things I consistently bring are my helmet, a gallon of water and a tire pressure gauge.  There is usually a hot dog vendor at events, so no need to bring food.

What were everybody's numbers?  I think the Insight has a bad coil.  I diagnosed it pretty easily, but no one local carries them, so I've gotta wait until one show up in the mail Sad
68  Events / Other Events / Re: Dyno Day 2015 on: February 04, 2015, 05:50:11 PM
I may or may not be able to attend now.  The Insight has a bad misfire that I need to figure out.  Bad enough that the CEL is flashing.
69  General / Technical Help / Re: Car scales and corner weight? on: January 24, 2015, 03:51:12 PM
Yeah, I'm down to host something in the spring.  I'd guess we could do up to 3 cars pretty easily.  If I get a lift in by then, it'll go oven faster.
70  General / Technical Help / Re: Car scales and corner weight? on: January 22, 2015, 08:31:31 PM
I have scales, but basically zero time in the near future.  I'm happy to donate the scales if someone I know takes responsibility for them.  They're not cheap and they're far from bulletproof - I dropped one and it cost me $250 to replace the sensor.

Alternatively, if we do this in the Spring (April?), I should have some time and the space to host.
71  Events / Other Events / Re: Dyno Day 2015 on: January 13, 2015, 09:07:21 AM
I'll dyno the Insight Smiley

While you're there, you should grind the pointy stubs off those damn rivets in the bumper!  I don't know how many times I've caught my leg on them.
73  General / Autos and Autosport / Re: Factory Five Cobra Build on: January 01, 2015, 04:00:30 PM
Are you willing to fool with it? I have a small Kubota tractor with a backhoe, if that would do any good.

I appreciate the offer.  Let me see what my guy comes back with.  I've got so many projects that I won't mind having someone do this.  I've gotta have over 1/2 acre covered in stone too, so my guess is that it will be really easy with a large piece of equipment.
74  General / Autos and Autosport / Re: Factory Five Cobra Build on: January 01, 2015, 12:19:07 PM
What are you going to grade it with?

$$$.  Someone with the right equipment will be doing it.  My guess is they'll need to dig some ditches to drain the water and let it dry out a bit before coming in with a bulldozer or something.
75  General / Autos and Autosport / Re: Factory Five Cobra Build on: January 01, 2015, 06:12:50 AM
Did you end up hanging the doors yourself?

David

Yeah.  It's a fair bit of work to get the horizontal tracks hung because There is no ceiling, but it's not very complicated to do.
