CVD, quick! Where is the cracka-wacka?!?

As long as the turbo/head/cams can support more airflow and be somewhat efficient at the boost/airflow level, then yes it should make more HP. There is possibly more potential with the 2.0 or 2.14 though, just because you can rev them to the moon and another way to get more power out of a turbo is to rev the motor high, if the cams/intake/head can keep making power.

Ok so here's what I've put together for the more newbies like myself and some PLEASE correct me if I am wrong with any of the basic facts:
(Note: I want to first give credit to "v8klla" and 98TSiAWD{from Tuners} for the majority of this information that I am listing below)
To build a 7 bolt 4G64 to bolt into a 2G------
'94-'98 SOHC Galant Block or '94 DOHC Galant GS Block
----To use the SOHC block there are 5 oil passages that need to
be plugged
'94 Galant GS DOHC Cam Sprokets
'94 Galant GS DOHC Head Gasket
'94 Galant GS DOHC Timing Belt
Either 4G63 or 46G4 7 Bolt Timing Belt Tensioner
2G Head or 1G head, using a 1G head will require the same swapping techniques as the typical 1G onto 2G swap
Still use the 4G63 Motor Mounts

Now my question is that I see everyone talking about Wiseco Piston part number bla bla and Joe Blow rods part numbers bla bla for this setup, but is there is there a 100% OEM setup that can be used for the 4G64 setup?
i.e.- crank, rods, pistons.........

2.4L at 8.5k would be equal to a 2.0L at 10.2k or a 2.14 at 9572RPM as far as air flow goes.

Why not 7500? thats not enough for your 2.4?

You can use the 2.4L SOHC 7-bolt out of the Spyder also.

You aren't going to get 20% more flow just because the motor displacement is 20% bigger. You would need a cam, head and intake manifold that could provide the 2.4l motor with the same VE abilities as a 2.0l. A setup that gives a 2.0l motor a VE of 95-100% might not be able to provide a 2.4l with the same kind of efficiencies. Some people think the 2.4l requires a more aggressive cam then what we usually run on the 2.0s. You would definately want a much larger intake plenum volume also.

The new thought is that HKS 272's actually hold a 2.4 back. The Crower 414's are slightly better. Maybe I'll just build a 2.14 and shift at 10,500. :bounce:

Very generally speaking, a bigger bore = more HP and a longer stroke = more torque. These 2.4's are mainly strokers (bore is a tad bigger) so you will get more torque gain than HP gain.

If anyone is into V8's just think of the 302/351W's or 327/350/383's. Build them equal and HP won't be drastically different, but the torque will be.

Bikes are also another good example. Their engines are oversquare. That is the bore size is larger than their stroke. This allows higher HP at higher RPM, but their torque is crap because of the extremely short stroke.

Im cool, I just dont take sarcasm too well... heh. ;)

Its no big deal I just wonder where you can come off saying why do i care at all... I was just asking about how much power the stuff can take, not how high it can rev. But now I know you need all different internals....

Great input guys! Yeah i had been doing a lot of reading latly on the two. I personally had thought that if you had a 6bolt than why would you need a 2.4L but steve/goat cleared that up ("I'm building one because I still want a streetable car, so spool is a concern, running 9's is not". Other good points were tossed around such as it was more of a 2g upgrade which i think it somewhat correct. All in all if i had a 6 bolt i would keep it build it up for high rev.. Or 7bolt of wanted to tried something new etc. I would do the 2.4L. The money issue comes into hand if you ask me... even though some of you are building nice 4g64's for pretty cheap...

Whats the cost of the full engine(4g64) costing everyone, est?

Thanks agian for the info guys, I knew you guys knew your SHIT! :dsmrule:

Ahhh, that is the whole problem. 90% of my jokes are sarcastic. Most of the people on here give each other shit all the time, join in! We don't actually mean everything we say.


Now for some 4g64 content:

Wiseco pistons $400
Eagle rods $325 (both from Elite)
Cam gears $50

I think pretty much everything else that gets replaced, should be replaced on a thorough rebuild anyway (front case, water pump, etc).

What kind of motors are in the dodge avengers? Would those work?

The newer ones have a V6 i belive...

Parts only, about the same as rebuilding a 2.0.

I've had a couple people ask me about building a 2.4 for them, I might be interested in building another 2 at the same time as mine, which might even save a bit on machine work. I'd have to figure out a price though.

*Cough* *Cough* ;)

There are a few using the "SA" version of the pistons (9.5:1) along with lower boost to make an engine with 300 whp @ 6k and 275 tq from 3500-6000 at 13 psi. The 6 bolts come with big rods, so throw the wiseco's on them would be the least I would say to do. The stock pistons are pretty fragile.

HMM! need some DsMers opions. Either i can go with the the 2.4L or i can go with a stock 6bolt... I would be building them both up.. Now i want a 91 cause of the slick looking front... but it lacks the 4 bolt rear. So basicly i could go 6 bolt or 2.4L with a 3 bolt rear... (it would be made into a 4 bolt in time to come)

I think that makes sense it kinda late...

unless you are 100% in tune with your car's drivetrain, you'll want a 4 bolt rear end LONG before a built motor.
You can go with either motor setup..
2.0's like to rev more.
2.4's are torquey usually and should spool a turbo faster.
Both motors have pros and cons, it all depends on your goals.

Goals consist of a high to mid 11 on pump gas :bounce:
