Description:
Hi everyone,
I'm parting out a 1999+ 13B shortblock I kept as a backup motor. It was idled, and a compression test done but the car was never driven. Cold compression was between 116/120 psi on all 6 faces using a rotary compression tester. Compression would increase once the motor is broken in. The car was sold and the shortblock is no longer needed. As the block has no miles, break in rules were followed, and the engine was only idled .. never revved.
Front Cover, oil pump, chain drive assembly, counterweight, bearings all NEW $750 for all
Would prefer to sell together, at a $100 discount rather than separately, if possible.(Cover $395 + Oil Pump $235 + Chain + sprocket + worm gear $145, counterweight + bearing$75 =$850)
Front Iron $600
Intermediate center iron $700
Rear.iron $600
Rear.stationary gear + bearing $525
N3G1-10-E1Y
Front stationary gear+bearing $525
N3G1-10-E0Y .. or both stationary gears/bearings for $995
e shaft. $1100
2 Rotors.+ Rotor Apex/corner/side seals/springs $1950 + $40 priority shipping As side seals are fitted to these rotors, i would prefer selling them with rotors, if possible.
2 Rotors.without new side seals + springs $1600 + $40 priority shipping
Rotor Housings $1400
Waterpump + housing/coolant tower $285
Front pulley/timing ring $325
Mazda OEM soft seal kit $400
These parts are all exactly as pulled.
The rotors look new aside from slight bathtup discoloration. The e-shaft looks new with no grooves on journals.The housings look new, with flawless runways.
Irons show wear along side seal paths, but it's not measurable wear as iron milling marks will confirm. Rotor seals (other than end seals) are labeled for the rotor and position they were pulled from.
Domestic shipping rates quoted when you PM your ZIP. Please add 3% PP fee if not selecting "family + friends" payment option.
Pics of Intermediate center iron will be added later.
