Hello Rx7 Boutique,
Having watched this item on yahoo auctions, i recognised the photos immediately as the same kit you have posted for sale.
http://page6.auctions.yahoo.co.jp/jp/auction/f148652001
Some of the details in your post caught my attention, could I ask you a couple of questions about the kit please?
1. As the auction finished at approx midday yesterday (australian time) have you recieved the kit already, or is it in transit still? I would love to know of any postal service who works that fast.
2. If you have not recieve the parts yet or even seen it in person, can you be sure that there is no shaft play or damage to any part of the turbo kit, as you have stated?
3. I carried out a google translation of the original yahoo listing myself and there was no mention of approximate mileage on the turbo. The above post by another member indicates that he communicated with the previous seller in japan to ask the same question. Could you please share with us how you determined the number of approx 4800 miles use on this turbo kit?
Having examined the original photos closely, and noting the significant amount of rust buildup on the steel turbo core, i would personally describe the item condition as "well used" rather than almost new which your figure would suggest.
While we at fdrx7.com appreciated your effort in providing a steady stream of low mileage aftermarket part, we expect all vendors to provide the most accurate and honest descriptions they can.
