My 79 Mazda 323, Powered by a Series 3 RX7 12a Engine. see the startup after 3 goes http://youtube.com/watch?v=-unlJ3XUWh4 And this is what I want it to end up like http://www.youtube.com/watch?v=wQqUt1_NDRE On a weigh bridge it came out to 780kg or 1700 pounds approx Mechanically the car doesn't have much left from the stock 323, the Tailshaft and diff is the only original parts left which has handled pretty good so far with almost 3x the original power been put through it. The clutch is a heavy duty unit and is connected to a RX4 4 speed gearbox wich is awesome but the ratios are a bit short to be ran on the highway. Moving to the engine, The stock 1.4 donk has been replaced with a Series 3 12a with the stock Nikki Carby and K&N filter. It is putting out 91rwkw @ 6100rpm The RPM was so low as the carby was running out off puff and was actualy losing power. Replacing the fuel pump and Putting through some Carby cleaner solution The power now starts to drop off at 7300rpm, so I'm confident of cracking 100rwkw (160hp) after a tune. Only engine mods are a DBR gilmer drive, Rx4 radiator, Ser II oil cooler (mounted behind number plate) a Alloy coolant catch can and a Rotorsport Engine Crossmember Exhaust is 2 1/4 mandrel bent system with a single muffler and no resonator, it's loud The interior is in pretty good order, it has Series 5 RX-7 Convertable seats which have speakers in the headrest A simple sony tapedeck and a 6 stacker controls the music, and JBL 6.5 inch coaxials in the doors, the stereo isnt connected at the moment as 1) you cant hear it over the exhaust 2) the speakers were so dodgy mounted to the doortrims they would rattle and shake all the time and generally sounded shithouse. Some custom MDF doortrims with embossing and map pockets is on the cards. Brakes and suspension were also upgraded to pass engineering laws, Volvo 4 piston Calipers and VH Commodore disc up front and stock rear drums with 626 heatsinks on the rear. Suspension is left stock up back which isn't too bad but the front has been replaced with Series 2 RX-7 struts and coils with an aftermarket Coilover conversion to make them height adjustable. Wheels are Performance Brand 14 x 6 with peice of shit Madison tyres on the back and Dunlop's on the front.
