Thread: Timing belt/water pump kits on ebay

  1. #1

    Default Timing belt/water pump kits on ebay

    These kits are selling for around $100-115 shipped. Are these worth buying?
    1990 White NA - SOLD
    1994 Black NA - SOLD
    2006 Red NC - GT with limited slip, HIDs, all OEM.

    Good question. That's on my off-season to do list. I haven't seen the listings but I'd very suspicious of something priced that cheap. What's the catch?

    The kit I am looking at says most of the parts are made in Japan by GSM, but I do not know how good they are. I started looking at ebay for these parts because I saw a post on miata.net that said some people had these kits and were happy with them. Any input from others would be appreciated.

    What is the savings vs. OEM parts?

    I seem to recall a thread on the pointy board a while back that generally praised the ebay Timing belt/water pump kits as being an acceptable substitute to OEM and a good price. Then again, it could have been a dream. My dreams have been pretty vivid lately.

    I just talked to Trussville Mazda's parts dept. and they said they will not sell the OEM remanufactured water pumps for 90-93 because they are a piece of junk. I will probably buy the ebay kit with the new water pump.

    What's all included?

    If it's just a TB and WP then no... if it includes the thermostat, thermostat gasket, idler pulley, and tensioner pulley then yes.

    Bonus points if it includes the valve cover gasket or CAS o-ring.

    There are a lot of different ones out there at different prices that contain different things. I was considering this one for a refrest of my 1.8 donor engine. It includes:
    • One New GMB Water Pump (Made In Japan)
    • Two Water Pump Gaskets
    • One Water Pump Mounting Washer
    • One Timing Belt
    • One GMB Timing Belt Tensioner (Made In Japan)
    • One GMB Timing Belt Idler (Made In Japan)
    • One Front Crankshaft Seal
    • Two Camshaft Seals
    • One Valve Cover Gasket Set
    Not bad for $120 shipped.

    That is a smoking deal!
    The idlers alone are $100 oem.
    I hope the smokin is not your car!

    I like OEM from Trussville, and have only had one throw out bearing that wasn't up to snuff.
    If there is a problem, you can call Marshall.

    I have not started the project because I thought about selling my car. Now, my wife wants me to keep the car for awhile so i will start putting some more $$ into it. I have been driving it daily to work.
