Is rue you can get 159mm long rods for the 64? If so, which pistons suit them? Would it be ideal having such a small piston? I'd like to where I could get my hands on this combo for my next build

 

156mm is pretty much the longest you want to go.

 

you can get 159mm rods. can also get 162mm rods... but they would require an expensive crank and pistons.

 

Im building a 2.4LR with Manley 156mm rods and Weisco 10.5:1 87mm pistons

 

We typically use off the shelf 156mm rods.

 

Are you trying to build a LR2.4 or just use the 4G64 block and build a different displacement?

at 2.4 156 is the most you really want to go, thats with the pin already moved up 6mm, same as a stroker style 2.3 piston, taking another 3mm off the crown to wristpin area i'd be wary about, if in fact even possible at normal compression ratios.

 

Steel rod only and it gets close with a 10:1.

I used that compression height in my 2.2 (in this case 25.7mm) with R&R and I had to machine the piston a little to make it fit. The JE I used at that time still had 8mm of crown thickness in the 10:1 and according to manufacturers I have talked to since, 6.5mm is the bare minimum. I would think it would mean you'd want a 10.5:1 or 11:1 piston to make it work right and have some peace of mind. In retrospect we'd never build a motor like that again, the 8mm of thickness above the pin on the rod at that compression height didnt work well. A steel rod would have added back what I needed most likely though I dont know the difference in measurement off the top of my head. I will find out though tomorrow.

159 with 10.5 would be ideal on e85, our e85 in australia isn't very stable and as such people are a bit weary of having to be stuck with e85 to get most performance from a high comp engine. at 9:1 it would be under the 6.5 limit wouldnt' it?

 

Agreed.

Yeah the dish would interfere I think. A 9:1 156mm is good to go however

 

You can get 162mm rods if you want to de-stroke the 4g64 bloks and have a super long rod 2.1 revving to 9k plus

Here is a thread from MLR taking about the 2.1 long rod using 162mm rods, 87mm pistons and a 88mm stroke crank on the 4g64 block.

Im look for piston for my 2.4 LR. 156rods. Heard of few people using stroker pistion. Is that the correct way or is there a company that makes LR pistons .

 

What pistons would you use for a 2.4l with 100mm crank and 156mm rod.

 

does anyone have a shelf stock 153mm or 159mm rod?

 

i need the answer as well
