As per title.

Will a '97 WRX Engine be CDB or semi closed?

... and will the crank be cross drilled and tuftrided?

Thanks

 

The block will be open deck.

 

So are there 3 types... CDB, Semi and Open?

 

Sure is...

 

Classics had cdb's on the early wrx's (and sti), open after that, new age have open on wrx and semi closed on sti's, no classic has a nitrided/cross drilled crank, those are only on the JDM twin scroll cars which were 2003 onwards.

Yes on classics there are only 2 types, open & closed. Thats if im right? Newage Sti have SCD.

 

Tony mate, when you say "early" classics... how early are you talking?

Mines a pre-facelift '97

 

pre 96.

 

Nice one, thanks for all the replies guys

 

sorry to jump in here but what will my block be are you saying it will be a CDB

I have the last of the V2 on a N plate WRX

thanks

 

Probably not unless its an RA, seemed to be the K and L plate 93/94 WRX's that had CDB.

 

Whats the difference like? Is one better than the other?

 

Its a stronger block, shame the internals are chocolate (but you wouldnt notice how strong the block is unless your running 500+ bhp).

Tony

 

Which one is the stronger block? Closed or open?

 

Closed

 

There are actually 4 types out there:
CDB with bore squirters.
Open Deck with bore squirters ( not many of these left out there now).
Open Deck.
Semi Closed Deck

I'd of not believed that until I split an ODB recently and low and behold it had squirters.

 

how much oil do these squirtes consume?

 

You can also get a CDB without squirters, as found on the 22b.
