I know of lots of places to buy sleeves, but very few who will install them.

 

with the proper know how..one could do it themselves

 

Actually, I know how to do it, but I don't trust myself to.

 

yea...that would be my case also

 

Isnt the LNF coming with vvt due to the emissions thing?

 

The LNF has VVT and can spray fuel into the exhaust to light-off the cat quicker (one benefit of DI), both reducing emissions.

 

so what about 2.0 liter cars having a perfect square design? all boosted mitsu motors (4g63) nissans sr20det

 

Sooo, if GM were to spend some money upgrading the 2.4l rods and pistons and spend the same amount of money into the 2.4 as they did for the 2.0, the 2.4ls would actually be better correct?

 

 

OMG LMAO

 

Oversquare motors do just as well. Perfectly "square" doesn't net you anything more than just over or just under has.

The 2.4L engine could have been upgraded, sure. Heck, the LSJ and LNF are more similiar to both SRT-4 motors than people would believe, and well, since the new SRT-4 motor is extremely similiar to the new Evo motor, well, there are more similiarities than differences.

 

lol wow this thread is terrible.
LSJ is a destroked version, 86mm bore x 86mm stroke. better for high rpm usage as in drag racing since they rev over 10krpm. you can't really do that with a long stroke motor without creating damaging crankshaft harmonics and all other types of bad crap.
There's more, but I really don't feel like going through it, though a built up 2.4 litre bottom end with an LSJ head probably would make some rediculous power with a turbo setup, too bad the one guy with that setup sold the car, or is

 

It was destroked to increase top end horsepower and lower piston speed for a higher redline and less wear on the engine.

 

To restate things in a different way:

The LSJ was two liters with a short stroke because GM was still unsure on its exact durability and didn't want a lot of warranty claims.

The LS9 is 638 horses for the same reason.
