Between the SDM or JDM both have advantages and disadvantages.

WRX.

The SDM wrx does not put out the power that the JDM does out of the box. The JDM WRX (which you really dont seem to see much of since the 02 model) comes with AVCS on the heads and a such better spool and HP. The SDM however come with a better gear ratio and brake setup.

The SDM also has no speed cut, and a speedo up to 260 I think. JDM cuts at 187.

The JDM runs 1psi more boost than the SDM, buy hey you can tune that.

SDM interior has a more sporty finish than the JDM.

SDM WRXs are more available on the local RORO market.

STI.

Both are the same except for the speed cut and dash. The SDM runs less aggressive igntion maps, AVCS maps, Boost Maps and might put out the same power but a takes a while to get there. The JDM is a lot more aggressive. Remember that can be tuned as well.

If its a matter of interior I would choose the one with better safety and power.

^^The SDM STi's, as with the JDM STi's from '04 on....get the twin scroll turbo AFAIK. The only 04+ STi that doesn't carry the twin scroll setup is the USDM car, which is EJ25 powered.

And WRX's don't have twin scroll turbos in any market around the world.

So.....I'm not sure what ImprezaDriver is talking about. Rolling Eyes

In terms of the WRX, the JDM is the more powerful option, because of primarily AVCS and different ignition mapping (to give 19 more hp on 98 RON octane). Other than that, the turbo setups, suspension etc are bascially the same. My only grouse with the JDM setup is that it's intended for 98 RON octane, which means that you WILL have to tune for local gas. The SDM's require 95 RON minimum, and from my experience with logs on twoSD cars (mine being one of them), they run pretty well out of the box on pump gas.

For the STi....the stock JDM Sti puts out 280 hp, with the SDM (04+) putting out something like 265. Few differences between the cars, other than emission controls, and the JDM carries more aggressive head work (bigger ports) and ignition maps.

Knight1, its not usual that I contradict your statements, but am I to understand that because the SDM is almost the same as the EDM or USDM, and the JDM is almost its own market that JDM customers will get worries out of ordering out of the US. That isnt true. Subarus are lucky that the USDM market accomodates ALL parts, both USDM and JDM. So nobody has any worries. The AVCS solenoids for example can be ordered out of the US as they have cars with it (same part number)

Not all parts you can get out of the US would be the same LHD vs RHD, but SDM, JDM, USDM and EDM part numbers are constant across the board. OEM parts are easily available and if the US supplier doesnt have he will take the order and have it shipped from JAPAN.

Many locals are dependant on the USDM market due to ease of shipping. From my experience getting parts out of JAPAN works out better, faster, and cheaper. The problem is the language barrier and the time difference.

Now Dion, if both are peanut eyes, both has their advantages and disadvantages. So arguments can be either way. The SDM comes with no speedcut and compatiable with our emissions and its newer. The JDM comes with AVCS (that magical power adder).

I would suggest go back to basic. Look for the one with better mileage, condition, mods (if any already bolted on) and get a mechanic to check out the rest.

the SDM has the lowest mileage, is in good condition...i had really like the JDM but d ting is one of the front seats black and the other one is blue Confused

pallie, the seats is nutting. We telling u that the JDM is better because we have experience with it. doh make a mistake that everyone is making. get the better machine. Someone will always be willing to trade, or u can just dye the seats if it pleases u.[yes the upholstery zips off for cleaning]

you can also get the seat by gobin in bamboo, or order it in.

they replaced the seat with a sti recaro

the 05 wrx is blue i will post a pic of both a lil later for u all 2 see exactly wat is going on

Knight1 · Posted: Sun Jun 15, 2008 7:57 pm Post subject:

^^Ah....STi Recaro. That's weird. Maybe the original seat was busted up?

Definitely gotta see these pics!

As a side note.....for those who may be interested......the 05+ WRX's (JDM and UK) carry a variation to the inverted strut suspension from the STi's of that model year. Better handling, stiffer, beefier...whatever you wanna call it. The older WRX's carry standard struts.

this is the 2005 SDM WRX 5k cheaper than the JDM

This is the JDM

this is the pic with the seat (notice the difference in both seats)

which would u choose?

Knight1 · Posted: Mon Jun 16, 2008 5:37 am Post subject:

They6're both RORO or are they local used?

If the White one (JDM) looks like that in real.....and is good condition, I'd be hard pressed not to buy that.

That thing has gauges already....and look at the rims. Those are Ltd. Edition rims off the WRX UK 300...made by Rays Engineering (same folks who make VOLK) for Subaru/STi.

Cool

NOw on the other hand, the white one may have been repainted. The bumper's been changed (or at least the side splitters have been changed) to STi spec. The scoop's been changed to the STi spec...and look at the portion between the side mirrors and the windows. That's white...when normally it should be black (look at the blue car and you'll see what I'm saying).
