more from the description...

Hi, and thank you for visiting my auction/sale. My name is Brian, and i have been a Master Automobile Technician for 22 years. The last 4 of those as a Master Trained Watchmaker.

I have been a huge fan of Toyota's all my life even before I could first drive. Back in 1986 my friend down the street, who was 14 years old at the time, called me on the telephone and said, "Hey, you got to ride down to my house and see what my dad just bought." So, i do. As I ride my bike up his parents 450 foot black topped driveway, the second bay garage door opens, and parked inside is a 6 month old Silver, 1985 Toyota Supra Mk2 5 speed with grey cloth. Wow! That is the coolest Toyota I have ever seen. Exotic car like in a sense to a 15 year old who's parents drove 60hp beetles. I knew right then that I was going to own one of those someday.

Fast forward to now. I have always built fast cars, and never bought them. My extensive automotive, and watchmaker skill sets have allowed me to be creative in building from scratch, motor swapped cars. For 15 years, i focused mainly on the 82-85 generation Toyota Celica, and Supra's working with the 7mgte, 22RTE and 1JZgte Turbo engines. My philosophy has been that drivabilty and reliability always take presidence over having max, head gasket blowing power. Always using the stock computers limits.

That is until one day, my friend stops over at my garage and says he was interested in building a 5.0 Ford V8 powered Mazda Miata. He says that a kit can be bought to do it.
My reply was that if I was going to put a V8 in Miata, it would be one from a Toyota. He says that "nobody makes a kit for that swap". My reply is... "We will make one"
__________________________________________________________________________________________________

This White Lexus V8 Miata (Car #2) (Serial #JM1NA3518M1210691) is my finest period correct swap, and without a doubt, the hardest and most complex I have ever done. Only 2 of these cars have ever been built in the United States to this high standard, and emissions legality.
The first was a British racing green prototype (Car #1), which is in a collection in California now, and mine pictured here for sale, which is car number 2.

It took over 2 and a half years, working about 16 hours a week to complete.
(I documented/logged 1,663 hours) @ $50 hr (my shop rate) = (Alot of $ )

I hired 2 proffesional welders and an exhaust pro of 15 years to make the exhaust. Which is a work of art in itself. One of the welders I needed was a pro at stick, and one to work with chromoly.
Myself, and 2 other guys designed a crossmember idea using the original, and built it around the engine using steel and chromoly tubing. Its also designed for ease of service of the engine, and the use of the Miatas rack and pinion steering.

Everything from the complete integration of the wiring (*Using OEM Miata to OEM Lexus plugs for the harness*) and full diagnostics (Check Engine/ Trans Codes), to the design of the catalyst systems, A/C and cooling system all had to be thought out, and carefully done. Even the Lexus fuel pump, as well as the Lexus fuel computer is used. No loud Walboro fuel pump whine behind your seat in this car. The Lexus fuel computer monitors voltage, and adjusts according to engine load and demand. Its mounted in the trunk as well as a sealed Optima Red Top high amp battery.

I'm a very type A person, so details such as quality, look of originality, and emission legality were vital with this build for me. Even down to the use of the OEM Lexus "V8" emblems that match the font on the cylinder head plug covers. One on the dash, and one on the right rear above the 2 1/2 stainless tail pipe.

Everything works, looks like a factory built sleeper inside and out. Uses a Borla XRS muffler that is quiet and refined. It drives like a Lexus V8 powered Mazda Miata, which is hard to describe. Its very fast, shifts buttery smooth and will chirp gears in ECT power mode.

The engine is a 1992 Lexus SC 400 displacing 4 litres, 32 Valves, 6 bolt mains, all aluminum construction and using a factory high rise crossflow intake. Makes 250 Hp/260 lbs of torque and is 100% stock in this car.

It uses the stock Lexus 4 speed automatic with ECT, and Lexus engine computer mounted in the Mazda's same stock computer location. It employs a later 97 Miata (open 4.10 rear.... safer for street use, so it wont spin you in a circle),axle set, and Miata powerplant frame. Driveshaft is an OEM Toyota 4WD Hilux/Miata that is custom made and balanced to 93 MPH by (The Driveshaft Shop in SC)

My car uses a California compliant Catalytic Converter for use in Pennsylvania. "All" of the Lexus emission controls operate the Mazda's full factory smog equipment. Its all intact and working....not there for looks.

Upgraded front brakes (Metal Masters) and front springs (300lbs)(Street car only). All 4 struts are new, and a precision alignment has been done. Car is fully serviced and needs nothing at this time. It's drivability is so stock and smooth, you could use it everyday. It never overheats or runs hot, and I have personally tested and driven it 10,000 real world miles. I use the A/C when its hot outside, even with the top down.

The Lexus SC400 curbed at 3800 lbs using 3.30 gears. The Mazda after the swap with the Lexus V8....2600 lbs with a full tank and 4.10's......no cheating.

This car is garage kept all year round, and I have showed it many times, including twice as Carlisle Import and Kit nationals. Many different types of car people were blown away everytime time they saw it, at any show. My Miata is an excellent alternative to domestic V8 swaps in these cars, where max power, racing and track use was not the main focus.

Car gets 20-23 MPG and only runs on premium gas. 10-1 compression is stock for this V8 from the Lexus factory. I spent $4000 just on the engine restoration and rebuild alone using only Lexus OEM parts. The engine had 92K miles on it when I pulled it from a complete 1992 doner SC400.

The car itself is clean and rust free. Paint is shiny. It has small dents on the body that are hard to notice on white, and could be removed by a paintless dent pro. The largest on the driverside door. I am not a body guy, only nuts and bolts.

It originally "is" an automatic car. "Original Miata shifter with neutral and shift lock out is working".

Top is 2 years old and has never been folded down with the window not being unzipped. The parade boot is brand new and used twice. Tires are like new.

***Note****The roll bar is not real. If you would want to take this off the street and race it, the bar wont save your life. Street use looks, not race.

Why the sale?
I'm getting ready to retire from the automobile repair industry. I want to become self employed as full time watchmaker to service, restore and repair Rolex and other high grade chronograph watches.

What you will get if you win this auction/sale.........

(1) The car.
(2) The original set of daisy wheels. (4)
(3) A very rare 1986 Toyota W-58 Turbo 2wd 5 speed truck trans with 88k miles on it I personally tested, and know is excellent. If you would want to convert this car to a stick, it can be done. All the parts can be bought easily for a stick swap if you wanted too.

****See disclamer at the bottom of this auction for (#3) Above****

(4) A complete factory stock engine crossmember
(5) A spare set of nice 97 Miata axles and 4.10 diff

Any questions or photos needed, please ask. If you want my home phone number to talk personaly about the car, I encourage it, and will provide it to you.
If you do decide to view the car in person by appointment and want to drive it, you must show me a valid drivers licence, and have money. No "joy drivers" with this particular car. Serious inquire only. (Reserve will not be disclosed)

Watchmaking tools,benches, equipment or fine mechanical watches such as...
Rolex 50th green bezel, Zenith Espada (original), Omega mechanical chronographs, Movado Astronic's and 1000 foot depth tested mechanical divers would only be considered for partial trades plus cash.

Paypal, or cash in person is the only form of payment. ( $500 dollar non refundable deposit required at the auction or sale end within 48 business day hours from the time of sale.

No warranty is expressed or implied. Car is sold as is.

Notary services available on site of cars location to assist you in the purchase, and title transfer. Clean title on hand.

These details can be worked out on the phone if you are from out of state, and want to ship the car to your location. I will easily work with you via phone, and have a 100% positive feed back on ebay selling my personal cars of the past years.

*I noticed that there was a flag concerning the odometer mileage that I was un aware of untill listing. Back on September 8 2005, New Jersey DOT messed up the mileage during testing.
I can assure you that the odometer in this car has not been tapered with, and that was a simple mistake made on their part.*

Again..... any questions....... please inquire to get my home phone number.

_____________________________________________________________________________________________________

Yes guys, some of you made it clear...... What?........ "Automatic?"

"How could you go through all that and not make it stick!" Sorry for being an auto sinner, as I was a purist at one time...BUT....

"The Truth Is".........I spent my whole life in the auto repair industry and.........

(1) It was made an automatic for one main reason. "Emissions". Changing this to a stick will void its Emissions status. This drivetrain was Emissions certified for the automatic only in the United States.

(2) If your not power mad........its 250 HP. It does not need more "Juice". Power was not the main focus with this swap.

If you need more power, then the Chevy engine is the way to go. No doubt!

The stock parts hold up better with an auto......"No driveline shock"

***Its why my car does not need all the re enforcement frame ties, huge rear, axles and so on.***

(3) ***The EPA in this country does not care how much more fun it would be to row gears***

Its purpose and design was street use and Emissons legality only.

********Check your Smog laws in your state before bidding.********** If you or your inspector has any questions, please email me or contact me by phone.


Regards, Brian

But it's an auto tranny. Since he is an expert at swapping the 1jz-gte, I wonder why he didn't choose that route.

I'd rather go with Flyin Miata's LS3 swap:

Yeah, totally ruins this otherwise very cool swap. A Miata with an automatic is pointless.

Automatic Miatas make the baby Jesus cry. Even cool ones like this.

An all aluminum LS1, LS2, LS3 is a much better engine to swap into one of these IMO. They're a lot lighter and more compact(not to mention a lot more power than a 1992 spec 1uzfe) I'm suprised he was able to get that broad shouldered, 4 valve DOCH beast to fit between the shock towers.
