As long as it'll make 3/4 of your power, I'll be ecstatic.
Funny...when I pulled it apart it had stock pistons in it...albeit hadn't run in 4 years...and obviously never ran with this combo because the pistons were flopping around in the cylinders, but...yeah. Could make a box of chocolates joke here...it was enough that my machinist was like WTF?!? Oddly enough, it cleaned up with a light hone...he even said the block was freshly decked and checked out perfect. Its like someone gave up half way through.

Good choice bud!
did you get the stroker turbo tuff Manley rods?
they’re a straight bean design to allow block clearance for the 2.3L application, and they’re a touch lighter than the normal 150mm TT rods.
Manley part# 14400-4
also, please take the Eagle crank to an excellent machine shop and have the machinist inspect it thoroughly!
And have them balance your rotating assembly to a gnat’s azz too!

You dont want that on a 2.0 block anyways. That pushes the wrist pin up into the oil scraper ring. Even 6mm higherer starts to get into that ring. 3mm keeps clear.

4G63 deck height is 229mm
1/2 of 94mm stroke is 47mm
rods 159mm
229-159-47=23
Pistons with a comp height of 23mm <<— no bueno.
throw that into a 4G64 and the comp height can move up 6mm to 29mm which is what is ran in a 2.3L stroker in a 4G63.
If doing a 4g64, it's easier to just use a shelf rod that is 156mm in length, and one of the (what seems like many now) pistons with the appropriate pin height. I recall ~2yrs ago no one made that pin height. Very cool there are shelf offerings for it now. Its the same pin height for 150/94 4g63 and 156/94 4g64. I built a 156/94 4g64 (I did use ER custom Wiseco pistons though), and IIRC Dallas did as well but with a shelf Manley piston.

How did you like the 156/94 4G64 combo?
I’m torn between the 2.2L 156/94 4G64 or the LR2.4L 156/100.

I like it a lot. Still breaking in the fresh drivetrain, but it has very good off boost torque. I'm not a fan of the 100mm crank simply for reliability concerns.

I also know of a few 6-bolt 100mm cranks that cracked buy they were high power dsm 6-bolt dsms.
I have a 4G69 crank that I may build, but I’m going to have it fully inspected and hardness tested before I commit to my build.
MAP’s 1000+ whp drag RX-7 runs an oem 100mm stroke crank 6-bolt crank and I’ve never heard of any reliability issues, but then again I haven’t heard anything about it in a very long time.
Yeah, the 100mm Manley forged and billet cranks crack.

I doubt he was gonna build a 4G63 with a 94mm stroke crankshaft and 159mm rods.

1/2 of 94mm stroke is 47mm
rods 159mm

I recently purchased a 100mm billet manley crank and fyi they changed the #4 oiling port it is no longer angled I feel pretty good about it.
