What classifies a car as an LSJ or an LE5 in the lists? Here are some examples. How would you put them in the list?


2.4L short block with LSJ head in a SS/SC car running an auto trans with and aftermarket ecu.

2.4L short block with LSJ head in a SS/NA car running an auto trans with the factory ecu.

 

to me a true le5 bottom/top would classify it as an le5. anything with a different top and bottom is a hybrid in my opinion and should be labeled as so.

 

That was my thought... however we'd need a "hybrid dyno section" with roughly one person in it lol.

 

Putting LS3 heads on your LQ4 doesn't suddenly make it an LS3. Food for thought.

 

If gen 1 block, regardless of displacement with LSJ head it is an LSJ

 

Ahh ****.. I came into this thread thinking you dynoed the tvs 1900

 

this haha

 

I don't think pulling the entire engine harness to run the LSJ head on a 2.4L LE5 would be worth the hassle, but that's just me.

Hell I'd call a supercharged LE5 a stroker LSJ lol.

 

These would both be in the 2.4 section.

 

So we classify by the block or the displacement then?

 

I would say by block and displacement

 

So what is my gen3 2.4 block with a 2.0 crank and rods and 2.4 Pistons and a LNF head classified as?

 

A 2.1l
