Exactly how much research have you done?

 

jst sayin i saw a guy who " said " his made 300 with spray so i'm guessin it would be possible on to hit 250 w.o spray lol

budget is key

it can be done

if a 2.0 can do it so a 2.4 should be able to pack more lemme do some research so i can shove it in ur face lol

if not w.o spray... oh well then i'm wrong lol


for example the reg 2.4 such as in the caliber rt has 175hp

if a honda motor with 160 hp can be built to 250 + while na then so can ur 2.4

 

2.4 in our cars stock will put us around 165hp. I'm not paying anything for the complete block & head. Here's everything it takes to make 200whp with a n/a 2.4:
Required Parts
Camshafts: Crane 22 or bigger, or a set of the crower custom grind cams (like 3 sets made?)
Valve Springs: Crane or Crower, Crower preferred.
Retainers: stock is fine, titanium if you want to be fancy.
Valvetrain: PT or 2.7 Rocker Arms, PT Lifters
Exhaust: at least 2.5", 3" is optional, exhaust dump for the track is a good choice or if you want a quiet setup using stock piping.
Intake Manifold: DOHC Intake Manifold can do it.
Header: Longtube Header, at least 21" long primaries, in the area of 27-30" is fairly common.
Intake: Cold air intake of some sort. Iceman, 2.5" piping, 3.0, etc
Throttle Body: at least a ATX 52mm, 60mm+ is preferred.
Cylinder Head: Full Race P&P. Regular DOHC, PT, or SRT-4.
Fuel System: 24 lb injectors with 58 PSI Regulator, or 30 lb'ers with stock 49 PSI Regulator. Adjustable FPR is optional and best choice.
Fuel Pump: Walbro 255 Highly Recommended.
PCM: MPP DOHC PCM at minimum. AFX or MS optional.
Tuning Hardware: S-AFC or Adj. FPR at minimum. MS optional.
Clutch: at least PT Clutch. Stock SRT-4 or stronger is optional.
Pulley: Underdrive Pulley
Cam Gears: Adjustables basically required for tuning. AEM, Fidanza, UR, etc.

Other optional things to do:
Remove the Balance Shafts
Crank-Scraper
Windage Tray/Baffle Kit
Aluminum Flywheel
Decking of the head (0.020-0.045")
Stainless Steel Valves, oversize won't hurt, but might not be much gains.
Aftermarket Box Manifold, etc. (AMM, Blackdog, etc)

Other Information:
The header will need at least 1.75" primaries.
A merge collector is highly recommended, if not required.
