Can't you use a free flow aftermarket cat back for SPEC?Quote:

You are open to do anything with the exhaust providing the pipe isn't over 2.25 inches in diameter and it must follow the stock pipe locations.
I didn't measure the pipe diameter but it definately doesn't follow stock pipe routes and there's a spare tire up under the car.
I'm going the TCB route so I'm looking for stock exhaust right now. I'm not looking to spend a couple hundred here and a couple hundred there as that adds up to a ton of money. Right now I'm needing to get the car basically back to stock form and running without going too far into debt.
Once that happens I can then look at my options. But for right now, I'm needing to spend the $ wisely as the biggest expenses, the roll cage, seat/steering wheel/harness, hardtop, and the suspension kit are still needing to be done.

I cut the above posts out of another one, since this subject looked like it could stand on it's own!
Thank you please drive thru!
Can I ask what may seem to be a stupid question...
CM, why didn't you just keep the last NA you had that was running and make that into the SPEC? I know it's too late now, but it seems really counterproductive... especially seeing that the original NA you had had some body damage already.
Just asking...
The exhaust is allowed to end past the rear subframe, so just cut that puppy off and throw the spare tire away. You don't even need a muffler, as long as it passes sound check, which it should. If you still think you need an exhaust, I have several donners that you can pick from....
Merv :drive:
Thanks Merv,
I'd like to take you up on that offer! This way I'd still be able to drive it on the street... ;)
Don't want to trailer it when it can pull a small AutoX type of trailer.
I'm on the other side of the world from you. but you're welcome to come on out. I've got a '90 and '91 parts car and a few others. I'm sure we can make something work. Actually, my '92 SM-2-B is on the lift so we could pull that one the easiest. It's probably in the best shape, too. I have a birthday this weekend, and I know Shelley has something up her sleeve, so I have no idea what my schedule is....... :sunny:
Merv
Thanks Merv,
Name the time & I'm there!
I'm on vacation until the 31st... Grandma is here now picking up the kiddo so my schedule is about to be WIDE open (except for 8am-9:30am tomorrow morning) until Sunday.
Raymond
I will see if Shelley can give us a window of opportunity, then you can :drive: to Springtown!
All I need is an address via PM and my girlfriend (talking GPS unit) will tell me how to get there. :DQuote:

I feel your pain trying to create a streetable race car, but once the cage goes in you are a health hazard to yourself in that car without a helmet.
Frankly, the typical SPEC tire budget is more than my car.
PM'ed ya.........
I doubt you are going to want to drive it on the street with the hefty front springs, especially if you have a race seat. It's almost as bad as driving an old fire truck, from NJ to TX, with an EMPTY water tank!
Merv :drive:
Do you take your girlfriend (talking gps unit) to the movies? Don't people around you get irritated? Makes life cheaper though at dinners and other dates. I like the idea of having a volume control on your girlfriend!Quote:

hey, a good exhaust is the Sawyer unit, I believe Ara at Alara racing is the seller now, it is pricey though.
I also know a cagebuilder locally that does awesome work and can make you a good deal. pm me for that.
Screamin'Screw, I only want it streetable to drive back & forth to events. I don't feel like trailering everything. That means I'll need to keep enough on the car to pass inspection, like the cat, eBrake, etc...
I have a friend that races an M3 out at MSR and he drives his back & forth to the track. It beats trailering everything. I know it won't be as light as other cars. I'm looking to have something that I can gain experience with on the track as well as AutoX. I also just want to build one. I've never done something like this before and thought it would be a lot of work and a lot of fun.
Merv, doubt it would be much more bone jarring than my B&T that I used to have. I had the KYB AGX shocks set on 4 on the front and 5 on the rear... (or was it the other way around) but it will not be a daily driver.
And BigD, This is the only girlfriend that I can get away with, other than Meg Ryan who is on the approved list. ;) Merv should be careful! Twisting some things makes the volume suddenly go WAY up.
It was a B**** tonight, but the head & block have been scraped clean and the shop vac kept things out of the oil & coolant passages. The head is on the car and properly torqued. The intake is also now on the car. It's just being held on by the 3 studs. I need to go get bolts! Every kind of fastener under the sun is in a box that came with the car... everything EXCEPT those dang bolts. I'm willing to bet the dealership doesn't stock 'em too.
I've been replacing some gaskets, o-rings, seals, hoses, and caps as I go. I think I made 4 trips to AutoZone and three to O'Reilly tonight to get miscellaneous parts and tools. I think I have every tool now needed for external engine work other than a timing light.
Once the intake/exhaust is done I get to do the timing belt & crank seal. URG. This is stretching out to take more time than I thought. I may not get it done before my vacation is up!
RJ
Does anyone know if the 1.6L 323 SOHC engine uses the same camshaft as the Miata?
My neighbor's son blew his engine and I'm hoping I can scavenge some parts. He said it made a pop sound and died... "oil everywhere" and I'm hoping that meant a blown head gasket or the oil filter loosened up and blew off and not a rod through the side of the block. I guess it depends on how LOUD that "pop" was.
RJ
The answer to that would be no. The SOHC cam controls both the intake and exhaust valves. The DOHC cams control either the intake or exhaust, but not both. :geek:Quote:

Well, the intake manifold bolts are missing... so another parts order has been placed. Also the hose fromt he back side of the water pump to the pipe over on the side of the engine bay has a 3" split in it. NO WONDER the car overheated! I found that after removing the header.
Got new studs put in the exhaust manifold and had some cracks welded in it. Had to order a gasket from Mazda for it - the muffler shop didn't have one to fit it.
Hopefully I can get those parts by tomorrow. If I can then I'll spend the day finishing up the assembly of the engine and then start on the crazy TB/WP replacement. Once that's done then I'm ready to start it up!
RJ
Well? Is it running?Quote:

Need to install: motor mounts, intake assembly, exhaust manifold & down pipe and do the timing belt/water pump/etc...
I did get the intake bolts and some misc bolts I needed... but I did end up ordering a few more small pieces that will be in Wednesday.
Titus, do you have the bolts to hold the heat shield to the exhaust manifold? If not, I'll have to find/order some of those too. I also need to bring the header by for ya.
Raymond
Do I have them? I am sure I do.Quote:

Having driven a Spec Miata on the street I can assure you it isn't AT ALL comfortable. It was more bone jarring and uncomfortable than my dropped Miata with the KYBs set on 8.
That owner did drive it down a couple of times to TWS but eventually left it down there until he could get a trailer and tow vehicle.
I have a stock exhaust off my 93'. I'm closer than Merv. I'd maybe be interested in trading you. My dad did the spare relocation, and it's given him lots of room to pack my mom's stuff.
:scratch: All of Shannon's spec Miatas have a bullet style muffler going straight out the back....which is a little off-centre of the bumbers middle.Quote:

Pulling the exhaust off of Speedie Jr. for you was the catalyst I needed to get me started on the transformation. Sunday evening I began tearing "Jr." apart. All the rear suspension/subframe/ and misc other stuff has been removed. Interior is 2/3 removed, and we are about $5 richer from all the change we found. Not only that but we have almost ten gallons of gas from the tank, and a new oil filter that was hiding in the trunk! Once I see how much damage, if any, is above the fuel tank, I will know how much of the rear I need to replace. I suspect I will be making the cut just behind the seats and replace everything behind the doors. Should know tonight!
Since JR is such a low mileage car(69k), I think I will leave the engine/tranny untouched for awhile, as it will take me awhile to get back up to speed. No sense building a "good" engine 'till I need it....... As this will be a part time project, I suspect it will be July 'till we make it to the Ranch for our maiden voyage. Perhaps we'll have a party :drive:
HAHAHAHAHAHAHA!
I'm sitting waiting (im)patiently on yet more parts to arrive...
I still need to install motor mounts, coolant hose, exhaust manifold & down pipe, intake, and do the TB/WP job. Haven't had time to work on it the past 3 days with the rain & family stuff goin' on. Hopefully I can get some of that done this week.
I'm wondering how and what to paint the car with. If it wasn't so dang heavy, I'd be tempted to paint it with reflective paint :D That'd be friggin' wild in a night race. I still have some hail dings on the hood to fix as well as some fixing to a couple of areas where the PO didn't sand it down to well before I'm ready to paint.
I guess Earl Schieb or one of those other cheap places will work for paint.
Anyone have templates or sources for vinyl graphics? I'm going to shop around for pricing on them and see what I can come up with. I'm also going to check with a former co-worker to see if he still has his vinyl plotter.
Anyone have any NA turnsignals they'd want to sell? I'm missing both up front and need those.
And Merv, I'd be up for a party! The next couple of weeks are going to be scarce for time with business travel happening... If I can squeeze out a weekend day somewhere in there I can come help ya work on JR.
RJ
Mmmm party at the the Ranch. Or a working tech. day to help Merv reach his target, and we can drool over the eclectic collection or "stuff".
Dropped the fuel tank, and to my surprise I only need to replace the trunk portion, from the right edge of the well to the left fender, just behind the gas cap! The rear frame rails have pulled in slightly, but I can push them back out, with my trusty little hydraulic tool (Harbor Freight) once I cut out the crunched trunk floor. Nothing structural has been hurt.....whoopie :)
Merv, that's sweet! You can use the clip you cut out. :D
