Hi guys,I would like to know if I can drop a Japan engine into my USA FD,and if I
can just bolt it in and go?
Any help would be much appreciated,Thanks!

 

The engine is the same. The wireing harness is a bit diffrent.

 

My car is an Australian spec but has a jap engine in it... boy is it good

 

from where are you gettin your engine ... i mean i need one too

 

You guys thinking of JDM motors need to read this carefully:

Make sure you get a compression check done on the motor.

These jdm motor warehouses like to sell **** motors that once installed reveal that they have a cracked apex seal or even worse bad coolant seals. They also can have rusted out internals from sitting for months with coolant in them. In my opinion, trying to save a dollar in the beginning of the project ends up costing loads more later more often than not.

The surefire way to get a quality engine in your car? If yours is trashed, purchase a reman motor from mazda. If you want it ported, have it taken apart, ported, clearanced, and built. All of the remans I take apart benefit from being re-clearanced.

 

Rich really has apoint here. Most these engines pulled out of the wrecked cars are in sad shape, and the seller really doesnt care becouse they are making money on it. If you do get on you should have it tore down and inspected in stead of just slapping it in and seeing if it runs.

 

JDM engines should be considered useful for parts, and you should be prepared to rebuild it. ANY long block motor you get should be totally broken down and have all the components inspected - just dropping an unknown motor into a car whole is foolish, IMHO.

That said, some of the better JDM engine sellers will give you a compression test for that motor. But, it's still pot luck.

And, the core motors themselves are identical - there's nothing fancy or better with the JDM motors.

JDM motors dont have all the emissions equipment so you wont pass visuals at the smog station, right?

 

Lmao, Get a grip, the japanes are a very honorable people.
Only judge if you know.

 

Pfft :\

 

Wizer words IMO

 

^He's bascially saying the same thing as goodfellas...dont get one expecting to drop it right in and have it run perfect for xxx,xxx miles, itll PROBABLY be in sad shape in some way and should be rebuilt and inspected.
PS:And just like every other race/ethnicity theirs plenty of dishonest people

 

it still might be smart to pull it apart if you can...japan has a lot of rain and very humid summers, so its easy for parts to rust. and sometimes parts sit there for a year or two.

and compression testing before you buy a used motor is just common sense.

for the price of a motor/front clip, vs the price of a basic rebuild, id rather just get a rebuild and have the piece of mind. just my $.02

 

Once again wize words.
But not judgmental.

Hate the way ppl think they are better just cause they are patriotic or self richious.

Iknow i know shuddap.

 

Are you for real? You obviously know two things about this subject---jack and ****. I've seen it with my own eyes, many times. The motors could be from Botswana for all I care. If you have nothing of any value to post, maybe you should stop yourself from hitting the 'reply' button. Thanks .

 

From my experience you'd be wise to rebuild it no question.

Jspec engines are a crap shoot at best. Good luck

 

Wow, I would like to Thank everybody! The community on this site is
second to none!!
Yeah,my first plan was to get the job done right,and was to get a rebuild done by
Rotary Power with 3mm apex seals and street port,but then I started thinking that
I could just throw a used engine in and build up the other one for single turbo duties.

So I guess I may go factory reman now,I've just heard people call them the 15k engines.

 

I've taken apart many brand new remans to port them, and they are almost always in very good condition, with many new or lightly used parts. As long as you have a reputable place porting and building the motor for you, there's no reason it can't last a long time
