Default Differences between UK STI & JDM STI

Apart from the Twin Scroll Turbo, what are the main differences between the Blobeye UK STI & JDM STI?

Thinking of getting a JDM model but would like to know what the differences are?

Thanks

Off the top of my head;

1. Clear Indicators.
2. RE070 Tyres.
3. Twin Scroll turbo with more efficient exhaust path.
4. Auto 7 Manual Intercooler waterspray.
5. Electric folding mirrors.
6. Auto/manual DCCD.
7. Red backlit intrument panel which sweeps on start up
8. Flare in passenger footwell (for when you breakdown)
9. Quick rack steering rack.
10. All the suspenion is different. Bushes ARB etc.
11. The JDM Sti weighs 1,440kg vs 1,470kg UK Sti for the 2003 model. I don't know why it is lighter though.

All of the above is comparing JDM STi vs UK STi and not a Spec 'C'

Can't think of anything else.

HTH.

That's about it for differences; if you're talking about the '05 model, both the UK and JDM STI have the same chassis setup and long wheelbase from the Spec C.

Engines are different, JDM cars use Hyperreuetic (sp) pistons which are stronger than the forged ones in the UK cars (150-200% supposedly)
Grooved crank for better oil distribution.
Some more electrical goodies over a UK car.
Shorter 5th and 6th gear ratio, not hectic on the motorway before people start saying it is just gives you more accelleration
Most other bits have been mentioned

Treated crank
Large port cylinder heads
More aggressive Cams
MY05+ have a more free flowing exhaust as std.

I semi-wished i'd of tried a JDM first. But i saw no black ones available anywhere at the time.

The rear wipe would come in handy for up-north though.

Thanks for all the replies!

I had a STI Type R a few years back so I don't mind paying a bit extra for insurance as the car spec does seem to be better.

Well, think I will try and keep my eye's open for a JDM model then better get on the phone to A-Plan as they seem to be quite good.

Do you have to be a certain age for A-Plan to insure you on an import as im 27? I know when I was looking around for me old JDM Type R some places wouldn't insure anyone under the age of 30!!!

Well most of the JDM's seem to be blue which I wouldn't have a problem with, or silver one to be different.
Black looks nice but it's a b4st4rd to clean/keep clean.... currently have a Black Civic Type R and have kinda promised myself not to buy another black car

Black is best

I've promised myself over and over never to get black again.

As soon as I see a car in black and dead clean I have to have it

Do the JDM cars come with the Magnesium Alloys as standard then? They look better than the UK standard wheels, and if thats the case atleast the insurance company's can't charge you extra silly amounts for different wheels

They were a factory option, they are a part of the drivers pack, the only car that had them standard was the spec c.

The drivers pack was the A-DCCD, quick rack steering, BBS alloys and RE070's
On the MY05's i think these came as standard.
