4G64 Block/94mm Crank/162mm Rod/4G63 Stroker Piston
Ok I am looking to build something different over the course of the next year and depending on how it goes swap this shortblock into my street/drag 2G next winter. Or is someone is very interested sell it maybe.
A long story short I wrongly ordered and had a 94mm Eagle forged crank balanced last summer. Since it was unpackaged and balanced obviously it was not returnable so it has been sitting in my basement gathering dust since then since it is an oddball crank I had no luck selling it. For this reason I decided that I would do what makes everyone not interesed in this crank, build an oddball engine combination and see how it works or sell it once it is a complete shortblock.
As the title states I want to start with a 4G64 block (6mm higher deck height than 4G63) utilize my Eagle 94mm crank with a 162mm rod and a stroker piston (28.7mm c/d) to top it off. This combination will result in a ~2.2l destroker with a rod ratio is 1.72. I believe that the increased rod ratio over the standard 2.4l rod ratio of 1.5 will allow for a very happy shortblock with minimal reduced torque and spool time. Also having reduced the rod angle should reduce the cylinder sidewall wear or bore ovaling hopefully increasing engine life.
On the street I obviously will not be revving this to 10k RPM but on the strip I want to rev higher than my standard 2.3l stroker allows me. The powerband of my T3 HX40 in the top end had not peaked by 8000RPM so even getting another 1000-1500RPM would increase top end and useable power without having to increase timing or boost
Some things I want to discuss is the parts combination which are all up in the air besides the block and crank. Things to discuss are aluminum vs. steel rods, piston brands and compression ratio and rev limit.
I have lots more to add but am running out of time for tonight and would like start getting your opinions.
