Hi, All

I'm fairly new to dsm engines and just had a few questions. I'm basically looking for a spare block for my 9. I'm going to get a stroker kit, but I don't want to pull my engine until I have a finished stroked short block to replace it. So my questions are...

What are the generations of the 4g63 and which ones are compatible with a mivec head?

Where can I locate said block either new (other then the dealer) or used?

I hope I didn't irritate any one but I didn't find anything useful with the search.

Thanks for looking!

 

the only block that will work with a mivec head is a block from a mivec head engine

 

Thanks for responding! The dealer told me something different, that the head could be changed throughout the last generation of engines. Some I have talked to have mentioned taping oil ports. And I am familiar with the first gen with the tranny on the right side of the engine. So I'm aware that a 1st gen won't work.

Do you know why the mivec head won't work on say an evo VIII block. I have bean building import race engines for about 12 years so you won't confuse me. Thanks Again!

 

if en evo VIII block would work, would an evo V one work?

if so, I have an evo V block for sale

 

I wish I knew I'll try and find out. How much are you wanting and what year is it?

 

its from a 98 evo V gsr. if the VIII bottomr end will work, then the V will too.

 

at one point i knew someone who had a whole ix engine sitting around...i wont mention names in public. pm me if interested, and ill let you know who it was

 

an evo 5 is prettty much the same bottom motor as the evo 8 mabye the waterpump and some other minor things are different.

saorland please pm me someinfo on the evo 9 motor im also lookig for a evo 9 engine harness

 

The later 4Gxx engines have additional oil drain holes relative to the early blocks, I am not sure what year that changed for the evo specifically though.

 

Now I'm really confused so mivec on the evo only controls timing and not duration?

Then it's very possible the blocks are the same. If that's the case then all these 2nd gen parts I see all over will work.

 

I think the mivec system works on the cam gear itself and advances timing that way if you are going to use an evo 5 6 7 block the water pump is different and you will have to get one to suit. Why not ditch the mivec altogether

 

JAPSPEC4G63, I'm looking for a 4g63 block.

ix block does indeed have different oil cooling setup over the viii so ix engine only would be safe

 

where are u at?

 

supposedly the evo v and vi blocks have larger cooling passages than the vii viii nad ix blocks
