How about 2.4 crank and rods mated to LNF pistons for a 2.4 DI turbo? Benefits - extra 20% displacement to spool larger turbos
What are the bottom end differences among the LSJ, LNF and LE5 anyways?

I think it will be awhile before we start seeing stuff like this with LNF's (or until people have there cars paid off at least). Took the DSM guys for ever to jump on board for a 2.4 DOHC turbo or 2.3 Stroker mix matching parts between the 2.4 and 2.0 block.

Block
According to the GM website both the 2.0 and the 2.4 use the upgraded Gen 2 block which has extra material cast in it. To bad the 2.4 crank isnt forged. Im talking with Ross on some custom pistons. They want $730 with rings. We carry Ross so I should be able to get them for jobber which is quite a bit less.

Mostly because you have to have both to figure it out . How many of us have a 2.4 complete assembly and a 2.0 just laying around to measure and swap to see what will fit/work? lol.

The problem with adding cubes is that you are still stuck with the same fuel system. Making 600whp on the 2.0 would be no problem if the fuel system was adequate.

that only equates to higher rpm for faster turbo spool up, iv been looking into doing some swapping around( aftermarket stock dimension) parts...unless your looking to make aloooot of power, probably non streetable, its not worth it as a dd...if you figure it out before i have the time and money at the same time, then please post a how to thread w specs lol

i know htta the LSJ and LE5 share main and rod bearing journal sizes, so my guess is all the journals are in the same place.
LSJ/LNF - 3.4 in bore and stroke
LE5 - 3.46 Bore 3.85 Stroke
i dont see why you couldnt bore the LNF out and sleeve the block and buy oversized LE5 pistions. alittle bit of headowrk and a good tune, it could probably put down some power

Remember that the LNF pistons have a completely different design based around the direct injection.

there will never be a stroker kit for the LNF because its already at 16-1 compresson ratio, any more and the direct injection will never work, the cyl pressure will be too high, unless took out the spark plug and coverted it to diesel.
#18
Totally false info here. And you can make a stroker kit with any compression ratio. It's all in the piston and combustion chamber design (volume).

STROKE THAT SHIIIIT!!!!!!
on a more serious note...youd be better off staying/building 2.4, building your bottom end right(forged and balanced), doing some head work(serious stuff not just valve springs), and turboing the livng hell out of it
