I would strongly advise you NOT to make a purchase based on prices you've found on google.
I can say that I've heard bad things about osaka and a couple other Montreal based companies.
Check out JHOT.. a NICO sponsor with a very good reputation and outstanding prices.

Another place that I recommend is JapaneseStarMotors out of Albany, NY. They have great prices and offer free shipping. In fact they have a RB25det M/T motorset for $2000 (shipped) at the moment on their website.. http://www.japanesestarmotor.c...ID=46
If you are looking for outstanding service and helpful owner.. Check with Luis at DragDriftAutox out of Washington State. I bought my engine from him and I was and continue to be very impressed.

Read the sticky threads again and make a wise choice based on good research.. Nothing bothers me more than hearing about some poor guy buying a junk engine or getting ripped off completely.
