2.4L Engine Build
Hey guys. The 2.4l build is underway and I just wanted to share a little bit about where I am at. I will keep updating the thread as I continue. So far I have picked the motor and pulled the head off. Within the next few days I hope to have the head ported and the valves lapped, then moving on to the internals.
On top of the current M62 setup, I am installing:
JE 9.0 Forged Pistons
ZZP Forged Rods
ZZP 2.4l(F23) Stage 2 Clutch
80# Injectors
2.7" pulley
and a few other things...
Quick FYI, I dynoed 257whp with a 3.1" pulley a while back. My goal after the build is to approach 350whp with the m62 on e85 and a solid 300+whp on 93.
After about 8 hours this is where I am at:

She'll either make power like mad, or you'll have a grenade with the pin pulled out on your hands, keep us posted on the buildup. We await the dyno printouts with baited breath.
So you lowered the C/R for the blower... I'm following along..
very interesting experiment.
You may need to upgrade transmission and cooling system, as well as brakes.

sounds interesting I have been running the roots style blowers for a while on my drag street car
With the whp you posted I think you would be around a 13.60 with the old build and low 12's with the new build on e85
Of course that's with good traction etc
Have you ever considered seeing what it runs either 1/8 the mile or 1/4 mile
Also how much did you have invested in putting the blower on originally .
Sounds like a great sleeper

I did go to the track with it a while back probably~230ish whp and did 15.1 @ 95. I hope to be around 13 flat as that is what many of the quicker SS models are running. I originally spent around $2300 for the kit.

Updated the original post with more pictures.
Progress update: I am hoping to have the exhaust side of the head port finished tomorrow as well as the cylinder honed/deglazed and the new rods and pistons installed.
Picking up new rod bearings tomorrow and also ordering a set of valve seals.
Check out the difference in a forged 900whp tested rod(ZZP) vs the stock rods which gm suggests replacing at 250whp. The JE pistons are supposed to be good to 1000whp...so I am good there too lol. The beefy parts are also a 100g lighter per cylinder than the stockers and good for a lot more. The JE ringlands are 1.7 mm thicker than the stock pistons as well.
