2.0 vs. 2.3/2.4

[Jordan Y.]

Which do you prefer? As I see it, they each have their pros and cons.

2.0 has the ability to rev higher, and the lower torque output puts less stress on the drivetrain. Conversely, higher rpm shifts put more stress on the drivetrain, and higher rpm usually means shorter engine life, just as a general rule.

2.3/2.4 makes more torque, and more power in octane-limited applications. Lower rpm is more street friendly, though I don't think wear is significantly decreased over a 2.0 at the practical limit for each, say 9500 for the 2.0 and ~8000 for the 2.3/2.4.

My preference- a 2.3/2.4 would be nice for a dedicated street car, but either can work well for a track/weekend car. I prefer a 2.0 for a track car as a personal preference, with a few little perks like gearing working out through the traps.

All my cars have been 2.0's and all of the cars ive worked on/been around except for one(Jerry built it,the owner didnt break it in correctly).I say 2.0 for a larger turbo application since the revs will help and 2.3,2.4 for a awd application since you can actually benefit from the torque down low rather than spin.

[Ender.]

The extra displacement of a 2.3/4 might help offset slightly the lag of spooling a larger turbo, where as in a 2.0 you would want a higher revving engine to draw out the powerband.

The usually theory is the more RPMs, the more power. Ive always thought stroker motors were pretty interesting and would be pretty nice in a street application with the availability of more low end torque.


Again it always comes down to the goals that you want out of the car. The 2.0 has been proven time and time again but a 2.3/4 could always make for a well rounded daily driven car, when done right of course.

2.0's have been proven time and time again, look at all the fastest 4G's Shepherd, Rau, etc. 2.0 .

Yeah but whats the car going to be used for? These guys here are strictly race, If you want to make good power and still have street driveablity I would prefer 2.3/4 over 2.0. But then again im awd, fwd guys I dont know unless you get a limted slip and some nice tires torque is real nice. :D :D

[Rdline1]

a lot of the faster cars around here are going to 2.4 motors. for a street car that extra displacement can help spool these monster turbos at reasonable rpms and make the same ridiculous power that the 2.0's can.

i have only personally built 383 stroker chevy motors.

but is it true. you can use a crank out of a 2.4 mitsu motor and slid it into a 2.0 4g63? what fitting is necessary?? what power can that crank handle???

also, whats all this about the flywheel or something else blowing apart on the strokers?

[boosteddsm]

I havent heard anything about flywheel problems. But I know that you can use the 2.4 crank and the 2.0 rods but you have to get custom pistons from wiseco.

Yes, you get a crank from a 2.4 4G64 or Hyundai G4CS and use it in a 2.0 block. You need special stroker pistons that move the wrist pin up, and you might need to clearance the block a bit to fit the rods, depending on what rods you use. The power handling of the crank is high, but I don't have have a specific number. Above 600 hp, for sure.

why reinvent the wheel? just get a 4g64 block.

Stock flywheels will blow apart, they get cracks in them and under power explode. It has happened millions of times, thats why they make scattershields and aluminum flywheels.


Wheres Ian when you need him. This has turned into a huge thing before, but I will always stick with the high rev 2.0. They are 4 cly motors, its not like theyve ever experienced neck snapping torque numbers, so why make a compromise to have some torque in a street car. Besides having to wait for more time and research to be put on 2.3 and 2.4s to be able to catch up to what 2.0 has and already done.

I think he's banned.

I know hes banned. Its was meant as an expression.
