not sure how many of you guys are into the japanese domestic market (JDM) but i found this good site. its got a bunch of JDM motors for really cheap with good feedback... click here

they've got just about everything from type r motors to twin turbo VG30s... the motor in 350Zs and G35s. just check out the link.

VG30DETTs were in the old 300ZXs, not the 350Z/G35. Those are 3.5L, something like VQ35DE or something of that sort.

Edit: I like how the Qs are shapped in this font.
 
Personally I don't see the point of importing an engine from Japan when you could just take the money and build up the existing motor.
 
It makes a lot of sense when dealing with a heavily used engine, which may not stand up to the pressure of modification.

I may be wrong on this, but what I've been told is that in Japan, law states that cars must have their engines replaced at the approximate equivelant of 30,000 miles. (Maybe it's 50,000 km?) The removed engines can not be resold in Japan. So, it makes a lot of sense to replace your old engine with a low-mileage JDM one when planning to do performance work.

Additionally, many cars were released in the US with inferior engines. The most common example is the 240SX, which was released with a 155hp KA24DE (or even the SOHC KA24E in early models), which was originally developed as a truck engine. The Japanese Silvia came with the SR20DET, a turbocharged engine that, in addition to having 205HP stock, was substantially lighter, and yet, more durable, than the KA24DE.
 
Id like to see the law that states one must change their engine every 30k miles. Also japans emissions are lower so thats one reason you see powerful engines there and not here. CA = land of stupid laws.
 
It seemed a bit dubious to me, as well. But I heard it from a source who usually knows what he's taking about.

I'm going to go ask someone who lives in Japan and see what they say about it.

However, JDM engines are also low mileage for another reason. Japanese cars are simply used less. Not only is most intercity travel accomplished by rail, but gas prices are extremely high.
 
Why buy JDM motors? Cos even used ones are better than a lot of the engines that foreign markets are lumped with. In particular and almost exclusively, I'm talkin 'bout performance engines.

For instance, RB engines are popular for drag cars, but aren't sold overseas or even in Japan as new.

In any case, we just import the whole car here to Australia. Being a RHD market means our imports are often 'grey' and quick, from Japan.

Not that anyone would bother importing a new DC5 Integra R though, just old SR20DET Nissans, and anything with an RB and 32, 33 or 34 in its name. Some Toyotas too.

Yeah, JDM engines are good.
 
Well, since JDM engines are importable to the US, I would rather have the whole front clip, for setup purposes. That site isn't that good, I have a list of engine retailers, if you need some, just say so.

By the way, I checked into that "law". As I had suspected, it was BS.

Could you post where you found this information........ cuz I have been under that impression. Every JDM engine site seems to have it advertised and every JDM seems to have 30-35k miles.

My understanding was that they either had to replace the motor at 35k or be taxed heavily. And this was due to the fact that they are extremely strict with emissions over there. I dont believe many people in Japan get to drive as much as we do here in the states because of clogged roadways, high gas prices, and limited parking.
 
I asked DriftXtreem on the Drifting.com forums. DriftXtreem is a company in japan that sponsors, in one way or another, almost 75% of the competitors in D1.

The forum member of the same name works for DX in japan, and is directly involved, at a relatively high level up the command chain, with modifying and working on the D1 and show cars the company puts out.

He's always the guy to ask when any questions about the way things are done in Japan come up.
 
OK, here are the replies I got:

miniflex - "it's not true....people also used to say they never did oil changes also....it's just something someone made up....

...but their smog inspections are more hardcore than california's smog nazi's!!"

So DriftXtreem says:
not even close. Yes we have smog but 30000 mile engines are a pipe dream it was a nice lie to sell s loads of them in the states. I have cars with over 70k and they are all perfectly leagal and smog compliant. As for the oil changes yes there are some fools that dont change there oils as they should but most Japanese are pretty anal about there cars and chainge the oils often.
