Hi peeps
Straight to it
How strong, reliable, good is a bored out 2.0 close deck block, bored out to 2.5?
Cheers

 

As far as I know people only bore out a 2ltr to 2.2. If you want 2.5 you are better off getting a 2.5 short motor.

I was looking into it before but funds wouldn't allow it comfortably. I'm sure someone with more experience in this field will be along shortly.

 

lots of history of that; the liners are prone to dropping before they mature...have a read of Dynamics thread for deatils. I have a destroked sleeved 2.5 CDB based on a 2.0 and its currently being rebuilt because of just that reason.

2.1 stroker would be a safer and more cost effective option most likely. If you really want a 2.5 then have a look at Frayz or Daz's threads, they both used pinned EJ257s.

 

Cheers chaps
Had been told that a 2L block not strong enough to withstand boring for 2.5 without other strengthening measures.

How good is the 2.1 stroker, strong enough to run 450 allday?
Any 1 running, reliable?

Cheers peeps

 

Isn't the JDM 2.0 capable of running 450BHP as it is??

 

Pretty much mate yes, Barring injectors,turbo and possible intercooler upgrade.

 

depends which 2.0 JDM motor

2.1s have run inexcess of 600bhp with the right supporting mods...

 

Newage STi JDM 2.0

 

As above, As the OP only wanted 450, The newage JDM block will cope with that, Why bother going to the expense of a 2.1 stroker if you only want 450 is what i would be asking myself,

Also it all depends on what useage the car gets, Track/Drag/Daily driver, These are the things you need to think about before spending any cash. Personaly i`d get the 2.5 off my list straight away, 2.35 would be the ideal choice but cost is a big deciding factor here, 2.1 is the next best thing but still going to cost a bit to get right.

 

Thanks
My engine has problem wiv the rings so running on borrowe time at the min.
I do agree what you are saying about the jdm, only thing, it's the gamble of getting a good motor.
I'm running a MD321T(not my choice, put on by previous owner) so was thinking of the 2.1 to I get the extra gases to help spool that bit quicker.
Thanks for the advise.
Anymore advise much appreciated.
Thanks

 

His original post asked about using a 2.0 CDB and increasing the capacity to a 2.5...that is far more expensive than stroking a 2.0 to 2.1 hence my comment, he only mentioned his goals in a later post
