Stupid Newbie Questions

I'm sure this is quite obvious to everyone else on the forum, but I was wondering if someone can tell me what OEM and JDM stand for?

I gather from reading other threads that they are parts built to factory specs, but I'd rather ask than not know something. This way can get the lingo down sooner and start asking more important questions.

 

oem -- original equipment from the manufacturer
jdm -- Japanese domestic market, ie, stuff ricers think is superior since it's from Japan.

 

and i bet you can guess what usdm stands for.

 

thanks, any other basics the new guy should know?

 

Edm!!!!

 

I bumped a thread for you, it'll tell you about every abberviation people could think of car wise.

well this is offtopic but its a newbie qeustion and i really want to know...so here it is. If thie present STI engine is 2.5 liter turbo other then the turbo makes it different from a 2.5rs? basically im asking if u add the sti turbo to a 2.5rs wouldnt the engine be same hp as the 2.5rs?

 

no, the only thing that an sti engine shares with a 2.5 rs engine is the 2.5 litre displacement, the sti block is a semi closed deck type and the N/A version (2.5rs, or any N/A 2.5 subaru) has an open deck.

 

o okay just had to ask thnx

 

no prob

 

And the compression ratio would be 10:1 on the NA motor. The NA engine will detonate on stock STI boost pressure.
