2.0, 2.3 or 2.4

Need help deciding on what to do. I have the parts to build any one of those motors minus the pistons b/c I havent decided on which one to do. I have a G4CS block and crank, both in excellent shape. Machine shop said the crank doesnt even need to be touched. Also have a 6 bolt 2.0 block and crank in excellent condition. My major mods are:

Crower Rods(Ross pistons, when i choose the motor.)
Victory Performance Manifold
JMfab smim
AEM Ems
t3 35r .82
272's
FP Springs/retainers
Precision fmic
pte 1000's
etc.

The only part about the stroker I worry about is what I've read about people breaking cranks. I dont want to spend all the money building a stroker and then break the crank. Im mainly going to stay on pump gas, unless at the track. My goals are mid-high 7's in the 1/8 on pump gas and 18-20 psi, and low 7's-high 6's on big boost. I like the idea of revving the 2.0 to the moon, but then again I like the torque the 2.4 offers as well. Right now Im kind of leaning towards 2.0 unless other wise convinced.

I would go 2.3. A torque monster on the street and very streetable.

You can even go with the 2.1 which is a 2.4 block with a 2.0 crank. This will give you a little more displacement and torque and still be able to rev high. However you will have to go with different rods and pistons. (Awaiting Dan's smartass reply)

2.3. I have one on a small turbo and love it.

I would go with the 2.3. I am currently building a 2.3 myself after months of research. If you decide to go qith a 2.4, then you have to locate another tb cover to fit the taller deck of the 2.4 and another set of cam gears. Everything else will work from the 2.0 and the cams gears will too, they will just be 1/2 tooth off.

Oh yeah, I have AEM cam gears too.

Oh yeah, I have AEM cam gears too.

The 2.0 and 2.4dohc gears are slightly different. The taller deck of the 2.4 requires a longer timing belt which in turn slightly changed the timing marks. The aem will work fine, you will just have to adjust them to compensate for the change.

i was a bit worried about the breaking crank things. I used a super low mileage 2.4 crank and had it polished only. I also am keeping my rpm limit to 7500 street and 8000 very occasional track use.
If the crank dies then likely use an forged eagle they have one now for pretty reasonable and might put in an eagle if ever pull the engine out of there again.

I do know quite a few people running 2.4s that have had no problems at all .
The 2.4 is great for spooling up big turbos faster, mellowing down crazier cams and giving better off boost performance an area where the 2.0 really sucks bad.

I love my 2.4 currently.
