No. They're different.

 

Ive heard different. But i want a positive answer if they are different or not.

 

They are definitely different.. you cannot take a 9 block and put an 8 head..

 

I know the heads are different lol im not that dumb. My question is, is the BOTTEM end the same?

 

again if the 8 head doesnt work on the 9 bottom then the 9 bottom is different.. I dont recall the difference but i had a 9 bottom and verified it would not work with an 8 head.. so that would mean they are different.. if the 8 and 9 bottom were the same then the 8 head wouldwork on it..

 

9 bottom end has extra oil channels for one thing for extra cooling which mates with the head so the above statement makes sense.

 

I knew it was something with oiling.. The crank is the same as far as i know..

 

the 8-9 blocks are different. But an 8 block can be turned into a 9 block with a skilled machine man. DTM has done this on a couple of occasion... I don't know the specifics but you'd have to contact them if you were looking to do this.

 

There is almost NO difference with the construction of the nine block in comparison to the 8 block. ONLY ONE difference....The nine has a large eye bolt orifice to provide constant volume and pressure to the MIVEC system. It can either be capped and used on an 8 head or an 8 block can be tapped and used for the nine head. Extremely simple. We built the first 2.4 MIVEC EVO 9 this way.

 

This is completely incorrect.

 

^hahaha

 

I have been looking on both motor and from what I have understand, they are the same. The only difference is that the 9 block have hole to supplied oil to the head(mivec), so if a 8 head is going to this 9 block you should seal this hole and that's it.

 

They are not the same blocks but a VIII head WILL bolt on to a IX block, we have an Evo VIII with a IX block and a VIII head. I dont think any special work was done for the swap.

 

Thanks for chiming in. I dont believe the things i hear from some idiots on here that say things theyre not positive about then everybody goes by that and give other people false info. Which is why i was waiting on someone who was positive.
