Have anyone de stroke a 4G64 to a 2.2 or a 2.3 LT? I am looking for the ultimate HP and torque and reliability! I have seen the 2.2 build on this forum, but I was just wondering if I should go to a 2.3 LT or go with the tried and proven 2.2 LT long rod set up. The plan set up is 96 mm crank, 86 mm bore, 10.0:1 C.R, and 160 mm rods (Rod ratio 1.66). The car is a full time road race car. It has in it now a 4G63 stroked to 2.3 LT. My thought here is, by using the 4G64 block with the 100 mm crank and a 156 mm rod, a R.S of 1.56:1. The road ratio will be better than what I have now in the 4G63. Which will make a pretty rev happy motor, wider power band, less piston to cylinder wall loading and better volumetric efficiency. What do you guys think? Your input will be greatly appreciated!

The long rod 4g64 is a great motor and many people build them including AMS and Magnus motorsports. It is the best combo to use if going over 2.0L but it is a little more work and a lot more $$.

 

Sorry guy for the mistake in my 2.3 LT calculations. What I meant was, have anyone build a 2.3 LT 100 mm stroke with a 156 mm rod with the 4G64 block and how well it held up? The road race circuits we have down this side are very tight; we don`t have sweeping corners and long straights like you guys have in North America. I need the torque advantage of a 2.3 LT.

 

Guyanas track is real tight thats for sure.
