So what piston would you run custom one ?

So it looks like the log rod setup and nothin be advantages with no disadvantages. Correct?

Correct

No real advantages until you regularly make power above 9800 and have a turbo that needs to rev. Disadvantages are no off the shelf parts.

Our drag car is still a standard rod 2.0L that runs 10,800 and has a best of 8.34@172mph.

can u run a long rod setup with a 2.3 4g63 block? I guessing you would need some pistons that move the pins up even higher than the standard stroker pistons.

I have been going back and forth on this issue, Talking to a few companys and reading what a lot have to say.

Mellon says 2.0
STM says 2.0lr
Br says 2.0lr
English racing says 2.0

Seems to me that its not going to make bugger all difference and other issues will come into play before the difference in lr to normal will show.
Oil pump failing, oil starving issues, possible altnator issues.

I have read that the L/R dose take some of the sidewall pressure off the block ( Br's forum ) so that has to be good, but i have also read that L/R can harsher on the berrings.

For me i am still undecided and i am very intrested in your build i have put mine on hold for now

I am in the same boat as you. I am also looking at doing the same build.

ive been looking over options for months and im set on going 94mm crank with 153mm rods, this should alow me to use stroker pistons and still have a better r/s (1.627) than a 2.3 but also up displacement to 2.2.

So that 153mm rod you are using is 3mm taller than stock right?
Whats the advantages on running 2.2L?
Let me see if I am right on this. A 88mm crank is a 2.0L, 94mm crank is 2.2L, and a 100mm crank would be a 2.3L? All of these going in a 4g63 block. Does rod length have something to do with his also?

you can run all 3 of those cranks with the standard 150mm rods and then all parts are off the shelf. people change rod lengths to to get a better rod to stroke ratio.

The percent change in R/S ratio from 1.7 -> 1.77 reflects the range at which only the slightest difference can be recorded in a research setting, which means that a human won't notice anything from the driver's seat.

You'll notice in my signature that my 2.0 is a LR. My reasoning at the time (6yrs ago) was simply that because I was having a set of custom Oliver rods and custom pistons made anyway, I may as well take the RS ratio of my choice while leaving sufficient compression height for an effective ring package. This put me into a 156mm rod (1.77 R/S), which gives about 28mm C.H.

Otherwise, it's not really worth going out of one's way or spending more to get there.

really good information in here!

Are you still running this same motor? Wow 6 years. And this is why I want to go back to a 2.0. It will last longer.

Ted B

iTrader: (6)

Affirmative. But then again, mine isn't a daily driver.

FL_SilverEvo8

iTrader: (15)

Thats still good though. You take it out and race it and stuff on and off for 6 years. That is really good I would say. Who built your motor?

im currently on my built motor that i built in 2007, 2.0 28k miles daily driven
