hey guys!
im wanting to go all out on my evo 8 here in the next couple of months and was wanting to do something a little different from the usual 2.0, 2.2, and 2.3 evos.
i was wondering How you guys think the 2.4L 4g63 performs copared to the 2.0 and 2.3?

I was also wondering what shops would you guys recommend for me to send my block off to if i do decide to go with the 2.4L?

 

I dont know if a 2.4l 4g63 is possible. Most people use a4g64 block out of specfic mitsu's (certain year Galants and Eclipses).

I could be mistaken.

 

The only way to get a 2.4 4G63 is with the the BC 102 or 106 stroker crank. I do not recommend either in a 4G63 as the R/s ratio gets poorer than a 2.3L

 

yeah i think ive read the same thing some where on the forums

 

thanks for the info.
what would you recomend as far as a 2.3L john? best place to get the block built, and would you recomend it over the 2.2 or 2.0?
im looking for a great 600+ street car

 

We build motors so of course I'm gonna say buy from us. On the 2.3 vs 2.2 debate it really depends on how you are gonna make the 600whp, pumpgas, racegas, E85? Do you drag race? Lots of specific things determine what is the best fit. I like the 2.2 since it is a little larger but still revs reliably to 9500 provided there is enough turbo to justify doing so.

 

Why dont u just buy a 2.4 block and build a 2.4 and sell ur 63?? 2.4 blocks are abundant and cheap. Just my 2¢. Ive built 2 in the past year and there just as simple

 

And thats the 4g64 block you're talkin about??

 

Long rod 2.4L is the best of every world. High RPM capability, tons of torque down low, and constant power every where across the rev range. Because of those qualities all packed into one motor, it has made every other build combination nearly obsolete.

And definitely go with the guys at English Racing if you want friendly, knowledgable service and top notch, second to none skill when it comes to anything to do with 4G63's and 4G64's. I sent my motor all the way across the US to them for a rebuild and when it needs another tear down in the future, it'll be going out to them again.

 

Cylinder wear will increase with the larger angle due to the bigger stroke. Rpm limit to keep the forces in check prolly 6500...

Somewhere on the EvoM site there is a thread with a link to a white paper describing what the forces are and the expected issues from 2.0 2.0 long rod, 2.2, 2.3 and finally 2.4. Rev limits are also discussed along with longevity as compared to stock motor

 

Yes its a 4G64. and about the LR version. My old 2.4 was long rod and honestly i dont feel its that much of a difference then a reg 2.4 but usually LR u will have to get pistons custom made, unless manley now has the on the shelf ones. My new regular 2.4 revs to 8k+ so with the extra torque and still keeping 4th during the 1/4 i see no point in going LR. I know they say less wall slapping but i couldnt justify the need. Just my 2¢

 

There are now Wiseco HD2 pistons available off the shelf and I do believe Manley has pistons as well. It's not really a matter of opinion as to whether LR is better than standard or not, it's fact that it's a better R/S ratio goes to the long rod motor and thats that.

So even if you only want/need to rev to 8,000, a long rod motor will do it with less stress on the internals than a standard rod motor will. High rev capability if needed, better r/s ratio for happy internals, and torque for ever. Win/win.

 

I wouldn't go that far. The 2.4LR is a good motor and lots of people are happy with it, but it's not the end-all option for our platform. Lots of people run 2.0L, 2.3L, or 2.2L for a reason.

 

Significantly less vibration compared to a standard rod. Where a 150mm rod motor always feels like the balance shaft is out of phase a 156mm motor is really closer to a 2.0L

I understand and agree.

But

I would say for a street car its pretty hard to beat, its better than a 2.3 in almost every facet, spools faster than a 2.2L and definitely kills the 2.0L in everything but redline. For a drag car it really depends on a few other options. The right gearing or tire height a 2.4 would work wonders as a drag motor also.

 

Well, I would go that far

But like I said, for all around performance that can do all of what the above mentioned motors will combined, you'll get more versatility out of a 2.4 period. Who wouldnt want torque and revs?
