Just curious as to how much you would pay for these and what would be the down fall of getting them?

 

these were on ebay and went to the winning bid of $375.... i was gonna buy them but something didn't sit with about the auction. i may have missed out on a good deal.

 

'99 twins just spool a little quicker due to the abraidable seal in them. You can't really run more boost on them or anything, so that price is about right.

 

The biggie is you need to make sure they're the 280hp twins. On the '99-02 cars, you could get either the 265hp version (with the same twins we have) or the 280hp with the upgraded twins. The year of the car doesn't tell you which version. A pic of the compressor housing so you can see the abradable seal is the real way to tell.

correct me if im wrong but these turbos dont make as much power up top as the stock twins are capable of. but they do spool a lot faster. my buddy has these in his car with a large streetport and its maxing out at 327 to the wheels but damn it spools up fast!

 

RE Amemiya put out 380PS with their Touge Monster, and it's running 99 specs. 380PS Should be around 360-375HP or something right? Someone correct me on the PS to HP conversion.

 

correct me if i'm wrong but those are the same as the ones we can get in US, if you're thinking those are 99/efini turbos/280hp version, they're not.

The ones that output 280hp should have turbocharger clamps holding the compressor housing to the cartridge instead of the c-clamp type

 

+1, ditto. check the serial number stamp. [edit: oops, sorry, i see you didn't buy them and you can't check, it's FRAUD, someone got ripped off (or a good deal on stock US turbos)]

 

Whaaat? Dude check your facts. They definitely can handle (a little) higher boost better, and they're $2600 new, so they sell for $1500 - $2000 used, depending on condition. I know, I've sold a few

Heck, you can't even get a good set of US twins for $375. Most low mileage sets I've seen go for $500 - $700...

Seller: "these have a black abrasive coating on them and to my knowledge these were the only turbos that had them. per mazda. and they have n3g1 on them which to my knowledge is the best twins made by mazda."

To my knowledge doesn't n3g1 designate them as being the 280 hp.

 

Maybe turbos bought directly from Hitachi through importers are different from those sourced to Mazda and possibly still have the c-clamp? Just guessing. I was recently shown a car that had the '99s put in it and the builder pointed out the same c-clamp verses bracket thing in addition to the N3G1 stamp. Keep in mind that folks on eBay and here in the forums often post the wrong photo not realizing the differences even though they have the part being advertized.

 

Granted, I know they cost a lot, but I'm not really sure that the price is worth it. I've also been reading (I can't find any threads though, I'll have to look later) that the '99 twins don't hold up to higher boost levels as well as the stock twins do. Again, I'll try to find those threads.

On another note, any pics of that button?

 

Even if that's true, you can't suddenly ignore the market value of something. Granted, it may not be worth much in YOUR eyes, but to tell someone that good condition 99spec twins are worth about $375, that's just plain wrong/false/insert negative word here LOL.

Sure. PM me plz and I'll get on it on Monday or so (I have an exam on Monday, so I'm not really getting back to anyone before then).

Thanks

But that's what he was asking, if you'll look at the title of the thread. "How much are these turbos worth to you." To me, not very much.
