First off it says it is a 4g64 block, so you would need one of them.
Guess I'm too late on my answer.

Yea a 2.3 can be done fairly cheap using factory hard parts. Factory 100m 2.4 crank, factory 1g big rods and stroker pistons, arp hardware. It would make a great street car.
If thats not enough these guys have kits starting at $1500 for the 2.3's.

Screw the stroker kits, they are expensive and unless you plan on making 800whp then I don't think they are needed. For your 6 bolt NT block to work, you will need a 6 bolt 4g64 crank (these are a little hard to find, they didn't make many 6 bolt 4g64 cranks) or a 6 bolt g4cs 2.4 crank. Then a set of factory sized rods, I would recommend going forged. I used Manley rods, and didn't have to grind the main caps down at all or dent the oil pan for the longer stroke. And a set of stroker pistons. These pistons are shorter than factory to accomodate for the longer stroke and same length rods. I picked up my 6 bolt 4g64 crank on the classifieds section for about $150 shipped.

Are you kidding me? A stroker kit completely redefines your torque curve. You'd want a stroker kit if you want to make any amount of horsepower more and still have good bottom end power.

I dont know, 1500 is a seems like a hell of a deal for a forged 2.3 bottom end with coated stroker pistons, race bearings and arp hardware.

$1500 isn't too bad, I guess the difference is dropping more money on a forged crank vs. an oem style crank. But $3200 for a 2.6L stoker kit? That's a little much. I love my stroker. Insta-power. My next build will most likely be a stroked motor too.

2.6 stroker sounds like a hella lot a fun!!!!
With 2.3 you get better low end torque and quicker spool on a bigger turbos. I imagine 2.6 is just more, better and more fun! Talk about smoking tires!

Yep and with a FWD you will go through front tires every 3-6 months.

I got relly excited when I seen 2.6 stroker..Then I got sad when someone mentioned it was the 2.4 kit, not 2.6..

I think its a stroke kit for a 2.4 block Bud92GSX. If you increased the stroke on that block you could reasonably get a 2.6 out of it. It would require a custom crank and rods though. And 2.4 bore stroker pistons. Which is what this kit appears to be, and at that price it better be.

It's a kit to stroke a 2.4L engine to a 2.6L.

IT is a kit to get 2.6..Whats the difference, just the crank and stroke..So instead of using the 2.4 crank you use the kit, and bam 2.6?

Not really. Its $3500. A decent 2.0 will break trannys. What do you think a 2.6 will do?
Theres an old saying by Smokey Yunick, Horsepower sells cars, torque wins races. Well it doesn't apply to DSM's. Our saying is Horsepower wins races, torque just destroys dsm transmissions.
Conversely, I want to build an open light rally car, and the 2.6 would be great for that, but it has way to expensive of parts in it for an n/a motor.

Strokers are great for street cars for more usable power. It all comes down to piston speed and what you building more.
FWD cars stay away from stroker motors
Look at SRT4s spin city with the 2.4 thats all they do

No one builds motors for pistons speeds.
A 4g63 has a shorter deck height, that's why you cannot use it.
It has custom length rods, pistons and a 106mm crankshaft.
Unsure why a fwd would want this you will have no traction and busted transmissions.
There is an evo that uses this kit he road races and does all type of things with it.
It's below the recommended geometry for a performance engine though (under 1.50 rod stroke ratio)
on Mr.Alex - EVO 2.VI TME - 700HK? - zatzy.com
