I have a gen7 accord (04), 2.4l ivtec, was wanting to know if its possible to attain the 210hp that is comming out of the acura with the same basic engine??? honda 2.4l-160hp//acura2.4l-210hp..... maybe intake, exhaust, cams?? not sure. I've been trying to get info on this for quite a while, but noone locally seems to know anything about it. ...And yes I'm new here, sorry if i posted this wrong..... thanks in advance for any help.....

 

If youre talking about the RSX-S, that's your first problem right there.

The Accord has a K24, which stands for 2.4 liters.

The RSX has a K20, which stands for 2.0 liters.

The difference in power is due to the design. The RSX is meant to be a higher revving sporty motor. I assume to make more power it has more aggressive cams and a higher compression. The Accord, since it's a beast, needs the extra displacement to make good torque. The low end torque is what makes the Accord move.

What i've seen recently is another LS/VTEC of the future:

Swapping an RSX-S head onto a K24 block. I'd look into that, but if youre really interested in making power, Hondata offers the K-Pro, and since the K series responds so well to mods, some basic mods and then Hondata tuning could gain an extra 12 or so hp out of your mods

 

the acura i mean is the TSX i believe, it has a 2.4 and looks the same from the outside.

 

its a different head. it has iVtec on both cams, as opposed to the accord hear, which works on only 1 cam

 

From a review of the TSX:

The powertrain links Honda's 2.4 liter DOHC four cylinder with a six speed manual transmission (five speed automatic optional). The motor is based on the U.S. spec Accord, tweaked for this application with higher compression ratio (10.5:1), a better breathing exhaust system and Honda's i-VTEC variable valve timing and lift. So massaged, the engine produces 200 horsepower @ 6,800 rpm, 166 lb. ft. of torque @ 4,500 rpm.

Here's the Accord:

In-Line 4
Displacement (cc) 2354
Bore x Stroke (mm) 87.0 x 99.0
Horsepower @ rpm (SAE net) 160@5500
Torque (lb.-ft.@rpm) 161@4500
Compression Ratio 9.7:1
Valve Train 16-Valve DOHC i-VTEC

So basically to differentiate, teh Acura has more luxury feel wiht more power so there's a 'high end' option that's out of hte Accord's reach.

 

sounds like too much to do to play with the head. any idea where i can find about that hp gain for the accd then? does air intake and exhst do much?

 

Intake, exhaust, cams and cam gears tuned with Hondata should yield some very good results

This is with K20 motors:

If you look, tuning is the key. After the cams and head job on the K20, tuning alone netted 6-10 hp throughout the powerband

 

I believe from what I have read that the K series will also have greater output by putting higher octane gas in it. I know for sure that the V6 output goes from 240 to about 265 when you use 93 versus 87 octane. (see dyno runs at v6accord.com)

Why not put some headers and lift the intake from the acura engine?

 

nitrous, :D that'll help you alot. plus, its fun to make power with the flick of a switch.

but yeah, accordselux has it right on the money on the difference.

 

thanks for the info. , i'll look into the nos. , i've heard zex makes a safe kit.....

 

The problem is it's illegal for street use (you'll be in deep **** if you're caught) and it costs money to refill every time.

The best would be to do some bolt ons and tune, or swap over the entire engine. Any internal modifications will do wonders as well after tuning. You could spend 600 on a proper nitrous kit and gain 40hp at the wheels at the push of a button and have to pay each time to refill it or you could get an intake, exhaust, and hondata for about the same price and gain maybe 10-15 hp at the wheels at all times. Cam gears and regrinds would cost about 400 and net a little more at the wheels consistently, i'd say 4-5.

It's up to you if you want short bursts of a lot or a little at all times,

You could also get a turbo kit, they'd run around 2500

 

now you've peaked my interest... i've looked for a turbo , but cant seem to find one anywhere!!!!!anywhere!!!!!....also where would i look for the intake,exhst,hondata etc. like i said i'm really new at this..thanks

 

Turbo kits aren't really in existence. You can get a Honda Element manifold (ask to buy the manifold seperately) from turbo-kits.com (or have a shop make one for you) and then get a REPUTABLE shop to do the rest. You'll need piping, intercooler, blow off valve, wastegate, turbo, injectors, various oil and vaccuum lines, new fuel pump, tuning, etc. But it should come out to around 2500 when all is said and done. I know it sounds difficult but if there's a reputable shop in your area (believe me, I got scammed out of 1800 on a turbo setup, go with the best) they will know pretty much exactly what you need.

The other things are pretty easy to come by. If you plan on turbo, dont bother with an intake, but if you'll stay bolt on, just get the cheapest eBay cold air or short ram. Then buy a K&N filter to replace the one it comes with, and put it in. It'll be pretty much teh same performance out of any brand name air intake for 1/3 the cost.

Exhaust can be had from Apex'i (the World Sport is very quiet), Magnaflow (all stainless steel and good sounding), Comptech, DC sports, and GReddy. Look into honda-tech.com sponsors, they offer a lower price for us, and you support the site.

 

thanks again, very much...i'll start doing my homework...wweeeeee

 

Oh **** something quick before you do anything, your car an auto or manual?

I dont know the strength of the new auto trannies, but I'm assuming it wont handle too much. Youd have problems with high numbers added on. So youd have to run low boost or less than 50 shot of nitrous and it would prolong its life.

 

real cars have manny tranny's....

 

Then youre good. You can feel free to double its horsepower

Better watch out though, a lot of the old muscle cars have auto trannys and they'll rip you a new one
