Well my question is whats the advantages and disadvantages of the 2.4 stroker kit over the 2.3. Is there really any gain from the 2.4. TIA for all info, i would really like to see replys from people that have either one.

 

Ask TedB

 

The 2.4 liter strokers use the 2.4 liter 4g64 block and a 100mm crank. The block has a 6mm taller deck height which allows longer rods for better rod/stroke ratio(safer high revs). The 2.4 block also has a bigger bore. It does not however have oil squirters like the 2.3

The 2.3 is bassically a 2.0 block with the 100mm crank from a 2.4 block. Its actually a 2.25 or so.

The 2.4 definately has its advantages, RnR racing does most of them. Call them for more info.

 

thats good info so thank you. Does anyone know what disadvantages there are to the 2.4 besides not having the oil squirters? If that is a disadvantage?

 

yes

Not trying to hijack the thread, but do you have to get the 2.0l stock block bored out for a 2.3 stroker kit?

 

The 2l block with a 100mm crank should be a 2.37.

You don't need squirters with forged pistons. Some people actually remove them and weld the holes shut.

 

The rod ratio on a 2.3 is EXACTLY the same as the 2.4.

 

It isn't 2.37 heres the math...

8.5 cm bore x 10 cm stroke

V of a cylinder = (Pi x r x r) x H

3.14159*4.25*4.25 = 56.75 roughly

56.75*10 = 567.45

567.45*4 cylinders = 2269.8(roughly)

so 2.27 liter we'll say.

 

How can it be the same? You'd have to have taller pistons. I'd like to know where your getting your information. With a 100mm crank on both but a 6mm taller deck height, you must have a longer rod. Unless the pistons have a taller compression height(which i cant see why they would but maybe i'm wrong) there woul dhave to be a better rod/stroke ratio.

 

2.4 = 100mm crank, 150mm rods, piston pin set at stock location

2.3 = 100mm crank, 150mm rods, piston pin moved up towards the top of the piston/deck (6mm).

The length of the rod doesn't increase, just the location of the pin in the piston.

In order to have a better rod ratio, the rod length has to increase which it doesn't.

What you could do is build a long rod 2.4= 100mm crank, 156mm rods, and piston pin moved up towards the top of the piston/deck (6mm), which would give you a better rod ratio if you wanted it.

 

ahhhhh, ok. I didn't know the stock 2.4s had taller pistons. That makes sense now.

 

Bump. I think I know the answer, just wanted to be sure.

 

Akido,

See my sig.
I have a 2.4 block with 2.4 steel crank with brand new Wiseco pistons for sale.
All block machine work will be done. Just buy rods and put it together.
