Get yourself a set of 7-bolt Eagle rods to match your Wiseco pistons and call it a day.
FYI, OEM Rod Length is 150mm.
Fixed ^^^ for you.
You are correct in saying that the 420a is found in the 2g NT, (and also Neons, Sebrings yada yada yada, and the 4G64 is found in the 2g GS Spyder 2.4L using the same 7-bolt 4G63 150mm rods too.
The 147mm rod is Tomei's sick attempt at making a 2.3L stroker out of a 4G63 using the 100mm crank, 147mm rods, and pistons with the wrist pin moved up only 3mm.
Tomei 147mm Forged H-Beam Connecting Rods Mitsubishi EVO VII VIII IX 4G63 03-07
This ends up being a rod/stroke ratio of 1.47 and using a heavier piston too.
Who the hell is talking about 420a's...
He mentioned he was rebuilding his 7-bolt, and he is a 2g GSX, so I assumed he meant 4G63.
FYI, 420a's use a rod length of 5.472" or 139mm.
Not trying to pick you apart BogusSVO just clearing up some information.
Thanks again for setting it all stright!
