What's your background for mechanical experience? If you have to have a shop do a lot of the work then, you probably would be better off with a turbo, unless you have a lot of money, either way all motor is a more expensive way dollar for dollar in the higher hp ranges.
Me of course will be all motor for some time, I can't see me putting a turbo on any time soon. Maybe somewhere down the road after the high compression motor is built, and slap a turbo on top of that, but not in the near or forseeable future.
I really like the torque the 2.4L puts out. So hen it comes time t touch the bottom end I'll be investigating this closer and what fabrication and modifications need to be done. Because it is not a straight swap. But eventually I may have a little help with that... If you don't feel that is within your ability then go with a 2.2L stroker from Howell, it drops in the same way your old motor came out.
Any way, keys to small motor hp: -Cams, a must, how big depends on your ability to tune, If you have the funds go with a stand alone fuel amagement and you can have control and get a better idle, trying to fool the stock ECU will only go so far. I have Crowers and love them, crane's are also good. You also want cam can gears so you can tune the cams to your set up. -And to supply air to the motor I suggest quad TB's, I'll be digging into mine over the next months to get everything set up. (do not try this without at least an S-AFC. -Exhaust: Do it all, header (4-1) high flow cat, and 2.5" cat-back -High compression in a key especially when you are running bigger cams with overlap. The overlap takes some compression away which you want them to do when running high compression. I say a good streetable compression ratio is 11.5:1. Going with 10.5:1 is on the safe side and very conservative. 12.5:1 if you have big cams and control over timing, to prevent detonation you might need to pull timing here, just depends on the rest of the set up. -A good ignition set up ihighly recommend, ignition amp, coil pack, and the ability to retard timing. -Good machine shop!!! this is key, deck plate to bore the block, good equipment, ability to get tight tolerances and for the love of God get it balanced. Blueprinting as far as I'm concerned should be a part of any motor build up, duh check all your clearances and make sure they are what you want them at...
And now for the number 1 key to getting this set up to kill: TUNING!!! Know how to tune your fuel system (whichyou will have to upgrade) how to set timing, adjust your cams, to make the car run safe happy and strong. Because if you tune any highly modified car wrong, it will explode. I don't care if it's NA, Turbo or Nitrous. Do it wrong and it will hurt, your pride, your pocketbook and your car.
