This is true in theory, but still unproven all the EVO's and DSM's are still using built 4G63's, but we will see.

 

you have a PM on the short block

 

you mean Curt Brown using this identical block to run 10.59 on STOCK turbo doesn't prove anything?

I figured that you were looking to rev higher, but you can go to 8k on the 2.4 all day long. how much higher were you looking to rev?

 

Nope, first it's Curt Brown Secondly the head is milled quite nicely increasing compression that's how he made so much power out of a stock turbo. Don't forget Shep trans, Tilton clutch 2900lbs, JUN cams all added up the 4ths improvement too.

For the record I'm not saying anything negative at all it's a great combo it just hasn't been proven in the realm of 9 second cars, yet

 

Yeah dude WTF. You have no idea what you're talking about.

Hey Joey, so this is where i'm confused, just clear this up for me right quick. When i look at the SBR website they have the 2.1L destroked shortblocks as a whole, but it says "4G63 2.1L Destroked Shortblock." Then i go to the destroker kit like what you bought, and it doesn't say what block.. But you purchased it for a 4G64.

So the conclusions that i drew were:

A) They are two completely different destroked blocks potentialy, one is a 4g63 shortblock all ready to go, while the kit is for a 4G64?

B) The destroker kit is interchangable between the two blocks, no big deal, either or works.

or

C) SBR has a typo on their website...?

Also something that throws me off is that i thought for some reason that Curt Brown was rocking the kit that you got, in a 4G63.. not a 4G64... But i guess it is possible that he purchased the whole 4G63 destroked shortblock from SBR. Either way I am pretty positive that he is using a 4G63.

 

I am believe this motor is good to rev 10.5K.

 

I am not aiming for 9 seconds... I want reliable high revving motor. BTW what 2.4's have run 9 seconds since you mentioned it?

 

He said Curt Brown... And in your original post you didn't say anything about a 9 second 1/4 mile pass. All your original post implied that that NOBODY uses anything but a 4g63 in an evo..

 

I think they screwed up on their site.

What makes a long rod work? There are many advantages to stepping up to a long rod motor over stock or certain types of strokers. A longer rod actually reduces rod angle overall so when measured in degrees, less are observed which reduces stress from vertical and horizontal impulses. During the firing portion of the stroke, the angle of longer rod is lessened over the standard length rod. Longer rods result in slower piston speed at the top and bottom of the stroke reducing bearing wear and wrist pin stress throughout the stroke. Nevertheless, lower piston speed at the bottom of the stroke is where forced induction motors benefit the most in that the ports have more time to be crammed full of pressured air over the same port filling time when compared to a standard length rod motor.

 

Yeah it looks like they screwed up to me also, for some reason that link takes me there, but i can't find that same thing when i try and go to it myself. But who cares, what ever.

So are all 2.1L destroked motors 4G64s? I swear Curt Brown said he is running a destroked 4G63? Which i mean is possible because some shop does do a 2.4L stoker on the 4G63..

The only reason i am picking your brain on this is because the 2.1L is my desired block of choice as well, but i am a little confused after searching and reading numerous threads.

 

I didn't say NOBODY uses the 4G64 is was pretty popular in DSM's. I'm just saying the 2.1L is not nearly as common as a built 2.0. Magnus used a 2.1L for a little while, but I don't know what happened to it.

I hope the 2.1L works great for him. He's going to need a TRE or Shep trans to make use of all that RPM though. Shifting at 9K+ can be a ***** with a stock trans.

 

All destroked 2.1L are 4g64.

 

How can you have a destroked 4g63? You need to use 4g64 crank

 

You didn't say NOBODY uses a 4G64 but you DID say, and i quote "but still unproven all the EVO's and DSM's are still using built 4G63's.

Now at the point when you said this i didn't know you were an educated member, so i didn't know at that point if you had ever even heard of a 4G64 before.. But now i see you were using this as a generalization in saying that (correct me if i am wrong) the 4G63 has more potential, and has better proven itself in the 1/4 mile and on the dyno. While the 2.1L is still trying to catch up..

Correct?

Maybe if you said this in your first post "I'm just saying the 2.1L is not nearly as common as a built 2.0. Magnus used a 2.1L for a little while, but I don't know what happened to it." You would have made much more sense. But that is already a gimme anyway, so maybe you shouldn't have posted anything at all.

Anyhow, does a 4G64 crank in a 4G63 make it now a 4G64?
