Im about to build a NA 2.4 to drop in a 1gn coupe shell, What should I do to the block if anything? I plan on going with Eagle H beam rods, 12.1 forged pistons, crane 22's, fully ported head, long tube, Indy intake and 60 mm tb ,,UDP, fidanza light flywheel, A/FX race pcm, and a r/t 3.92 tranny...Is this a decent combo?

thats a good combo.. dont forgot to get adjustable cam gears to tune those crane 22's..

in my opinion N/A is the way 2 go

maybe try a itb setup with it and go mega squrit to tune it right.... also use 24ld injectors.... you would get some hella power with that setup combined with this i mentioned.

Thanks guys, speaking of tuning, how hard is it to tune the megasquirt? Also the cam gear adjusting, Is that something that needs to be done on a dyno? How do I know where to adjust them? The "tuning" is what scares me the most. I know there will be alot of it to do to make this work and its something new to me. I guess I will have lots of questions in the future...Hope I dont get too annoying...Thanks again..

With #22 cam's you are going to want to upgrade springs,retainers,and another thing get a valve job,maybe bigger valves...

i'd probably lean with a pt trans as opposed to an rt trans. driving hard i killed first gen trannies alot wheni still drove mine onthe street.

I would probably stay away from the fidanza flywheel and go with a spec or a competition personally, but again, thats me. I have a bad taste whenit comes to fidanza, too many broken cam gears and flywheels for my taste

As far as your direct question as to what to do to the block, crank scraper for sure, I dont recall what 2.4 pans moroso has available, but i'm pretty sure they do have one, that would be a wise investment as well.

12:1 with 22s, not a good combo. Need more cam (bad choice with a PCM) or less compression.
