I'm not too sure whether this belongs here or the tech section, but anyway, here goes.

I have a 5-spd 2000 Accord coupe, pretty much stock except for suspension and I have a new exhaust sytem on the way. However, what can be done to increase torque and power without going to FI or a H22 swap?

I've read about a H23 header swap by PirateMcFred, but as he posted, that was more an experiment than a project. Is there a sure way to do that? or else what else can be done to bring out more from the F23 while staying within a reasonable price bracket?

 

NOS, seriously.

 

I'll keep that in mind, but frankly I'll rather stay completely NA.

 

what's your price limits ? before we boost'd the 02 accord auto it was pulling really nice with some dc sport headers (ceramic) and full exhaust ...(magnaflow) - custom pulleys -
give us something to work with here... how much money do you want to spend on a setup?
That exhaust that is on the way is it a full exhaust system ? cat back ?

 

lose about 500 lbs. and you will notice how much torque the f23 really has

 

I've got a full exhaust system, DC sport headers, Apexi exhaust, and a hi flow OBX cat. How much gain do you think that will get me btw? I havent installed them yet.

I'm looking at something I can upgrade in stages. For now, my budget would be $1k I suppose.

 

i would find a Vtec controller, your exhaust should give u a little more power at least u will be able to hear it. u could get an intake manifold and throtle body but ur better off just saving the cash and doing the H22 swap u can pick up a motor for about 1000 bucks and u can use the tranny u have now just get a clutch, flywheel, exhaust header, and an ECU ive done the whole swap in my 97 for about 1800 bucks if u can do the work youself

true, F23's have more torque, **** stock, than an integra type R


get some good bolt-ons and lose some weight (driver weight too) and it will be all good

x2.

Do you have F23 A1, A4 or A5?

Seriously... $1,000 is not much of anything to spend if you are trying to get real horsepower. Remember - NA builds are always the expensive way to go. If you can install cams yourself - they will be less money for SOHC than DOHC since you only have one camshaft. Again, if you can do work yourself - you might be able to bump the compression ratio with new pistons.

Also - check out http://www.phearable.net
if you can get away with it in your state (smog) convert to obd1, get a chipped ecu, hondata and get it dyno tuned! i.e. adjust fuel maps, ignition timing, cam timing if you are able, change vtec crossover for best power curve.

All this could get you some real horsepower... and not just that "bolt-on feeling." Again, if you can do engine work yourself, it'll probably run you about $1200 plus the tune.

 

Mine's an A1.

Are there high compression pistons, performance cam shafts etc available on the market for the F23A1? Or do I have to get custom fabricated ones?

 

Sounds like you have the basic bolt-ons covered.

WebCams offers cam regrinds designed by BisiMotorsports. If you're staying NA, you might go for the stage 2 regrind, but you'd benefit the most after tuning it. A chipped p28 from phearable.net, OBDI conversion harness from boomslang.us, Crome, and a good tuner with a 'good-buddy' discount should put you around your $1,000 mark, with very nice yeilds. However, if you forsee going boosted in the future, the stage 2 regrind has too much overlap, and will result in boost leak.

Also, I'd pm Bisimoto and see if you'll need to upgrade your valve train for the stage 2. I can't recall whether or not it's required.

Hope this helps.

ive also heard of a couple people using rsx-s pistons and making some impressive results. im definitely going to try it on my next build

I covered this in a thread a year or more ago. It's possible but there are a couple things to look out for as well.

 

thanks you guys for all the advice. I'll think over it. I'm not going to do anything to the car after the exhaust switch, due to a pretty packed schedule, but I'll probably do something over the winter

 

good info fellas!
