If the 2.5L was a direct swap, that would be sick.

Why wouldn't it be? You can get a 25 in a Mazda 3.

I made 164.6whp and 136wtq on my 2.0. Bolt ons are "Ebay IM" F2 header and exhaust with Fswerks CAI. I rev. up to 7200 with stock internals. I have 168,00 mile on the motor and no issues. I know this thread is a couple of days old but thought you might want to see some actual dyno numbers. My tune is from Redline performance here in NC. Hope this helps.

Just think what a set of cams could do for you?

But as soon as you go bigger turbo and add cams torque isn't as high, 420whp 380wtq. Rpms got pushed up bc of the slightly bigger cams which is a result in torque loss, you can also lose low end torque by switching intake manifolds as well.

And as for you to say 2.3 turbo could make more power, till you hit a certain amount of hp or big enough turbo then the 2.0 will make more due to it being able to rev higher and also bigger strong since the piston pin isn't moved up on the piston. And yes I have seen this happen when stroking a motor where the piston pin was too high on a motor with a turbo.
I'm not sure if he understands that horsepower is just a function of torque. If torque is constant then the only way to get more HP is to rev higher. If torque is not constant but large at the beginning and tapers off then the HP will raise and plateau. If the torque starts low and then jumps at the upper ranges then you have no HP at all until the torque jump which at that point becomes ridiculous.

I imagine the second SRT example was due to the cams having more overlap. A small turbo will spool quickly and run out of breath. A large one will take forever to spool and then become a monster.

An ideal NA motor has a flat torque curve which will yield a perfectly diagonal HP curve up to redline, i.e. a rotory.

Interesting debate but how much have we helped the OP?

Forced induction isnt outa the picture but i dnt wana go over 8psi. So im looking for ideas i wana get a build sheet done n get at it. Stock trans okay i have a 5 speed also axle options exhaust i dnt wana have an overly loud car but i would like a nice hey here i am but not holy s what was that lol. Intake manifolds heads cams looking for direction

Add a set of cams, fwerk's header w/ Fwerk's stealth system, cossie intake or do a sheet metal intake, CFM's TB, of course a 91-93 octane tune w/ rear o2 senser & egr delete. For more mods= forged pistons/ rods/ ranger crank & SS 1 piece valve's. Add a Torsen & CFM's tubular control arm's to help get the power down.
They you go!

Hey HAPPYHANDS, have you ever run that setup at the track? How is it on the street? Lose the low end with the IM? Any suggestions?

Only quarter and eigth and mile. In the 1/4 it did 15.1 at 93. In the standing mile it does 130mph. I get 31mpg. That's city and hwy. I live in the mountains. Got 34mpg when I visited fl. I lost 13wtq I've I remember right. And gained 14whp . The car got faster in the standing mile. I gained 3 more mph.
