Only place to down pack this motor build is er hand down if not, your looking for possible failures with these other builders..I myself ,love the old school 2.0 with 10.1 pistons and a good ported head.There's need for all that tq on the street to shred gears in the tranny and t. case.

 

Finally, some else here that really knows what he is talking about; I absolutely agree with you.

I still believe that is better a 2.0L for high performance street aplications; instead that the very risky 2.4L.

 

I would take 2.4 over 2.0 any day. What is risky about it? I guess having an inexperienced builder build it without knowing any clearances just slapping parts together and hoping it works

 

lol

 

the 2.0L is actually better for drag race motor,more rpm=more mph.if i wanted an all out drag motor i would stick with 2.0L or 2.1L,in fact the 2.1L is actually superior in every aspect imo.

but for the street the 2.4L is best,there is no replacement...


i actually am hoping someone starts having success with the 2.6 4G64 as i would love the extra 30% displacement with a 3586 or a 6262 on the street,man it would be a beast and all you would need is about 7500-8000rpm for a nice wide powerband with gobs of torque.

check out DCR with his 2.6L SRT4 motors,that guys builds some bada** motors and no EVO can come close to his SRT4.i think he's in the 7's at 190mph and putting down 1800whp,all on a 2.6L motor.too bad he's not an EVO guy.

Mason, I'm on the exact same page. I asked about the 2.6L awhile back. Unfortunately the only company that makes the kit is Brian Crower. If someone put together a 'long rod' version of the kit I think it would function quite well.

The current kit reaches ridiculous piston speeds at like 6K rpms so it's useless for a high RPM application, but would have a FAT powerband on the street.

 

it would be a profitable project for someone if they could build them consistently.i think BC had several failures early on in the production,and i wouldn't try one.but i might try one from a different builder.

when i first bought my EVO,and i was reading on the net about motors and stuff,i came across that 2.6L by DCR i figured the SRT4 motor would be a direct fit to the EVO and i was pumped.i called DCR with credit card in hand to buy that stroker and he said it's completely different.it was depressing.i guess the 2.4L will have to do for now.

 

Oh, it would definitely be a profitable project.

I don't know much about the SRT-4 blocks. What do the bore size and deck height look like compared to the 4g64 block? I wonder what mm crank and rods he uses in those motors. I couldn't seem to find it anywhere.

The crank in the BC kit is far too big and, from what I've read, gives it a terrible R/S ratio and thus a ton of rod angularity as well.

If someone developed a kit with a 104mm crank with 152mm rods, that would allow you to use the same size piston that's in a LR 2.4l and a 2.3l, and you'd have a 2.5l if you're bores were 87.5mm.

That would give you a R/S of 1.46 compared to the LR 2.4l's R/S of 1.56 (I think).

I wonder if it would be efficient to build a custom piston with the wrist pin moved up even more than the LR2.4l piston.

I could be so far off here it's not even funny, but I would love to build a higher displacement motor if it's possible.

 

There are plenty of people including myself who have success with the 2.4L. My friend has the same build as my butt he has a CNC ported head and gsc2 cams. He will be shooting for around 800 in a few weeks.

Why do shops use the 2.4L blocks to make a 2.1L out of them? Is it not for more RPM, better R/S ratio and being able to handle more power due to the 2.4L blocks being stronger?

 

+1

 

you guys are arguing with someone who doesn't own a Evo.

Not worth it.

If 2.4's were time bombs there wouldn't be an abundance of Evo owners using them.

 

How many owners of these 2.4L beasts out there can you count? A thousand? I don't think so. Maybe 300hundreds, not even 500hundreds for sure. (I mean only counts those who have the 2.4L *high performance built only* - I am not talking stock* engine actually working, and turning on, and using in their engine bay to the date), not at the garage floor or blown in pieces).???



Note: Currently I don't own an EVO, but I will own a 2012 or 2013 EVO X GSR this winter; so when I owned it, it will be newer and more worth it, than yours. Thanks. Also what really is not worth it, is that Fuji Heavy Industries that you also drive.

 

You have no ****ing idea how many ****ing people own a ****ing 2.4L holy **** stop trying to prove your ****ing point. Keep driving your ****ing 300hp lancer around and quit worrying about other people.

When I posted a reply, it takes to me some minutes to make some correction to it, don't quoted me so fast, because then the replied will remain with less info. Read my reply again, I know millions of 2.4L are out there, but I am talking about how many are being used for high performance built, and that are actually working, not blown, or at the garage floor getting rusted. I am not that idiot, so stop you making so much hate, I have freedom of posting, since my comments don't ofense anyone, but you only have to use ****** words; you just better ignore me then, because you are not forced to read my posts. Thanks a lot. God bless you man.

 

about 18k miles on my 2.4 here. no issues.
