Q about DC5R

**skimboynemo** · 25-10-2008 08:18 PM

hi, everyone, i'm a newbee to a DC5R. and jus wondering few question about the modification which i gonna do on my K20A.

1. i got a Apexi air intake kit atm, and is it gonna be better if I replace by a Mugen Air intake kit?

2. what can I do if I meant on bringing more hp under a $2k$ budget?

3. also wondering is there have any specialist or mechanic on tuning DC5R in Adelaide.

thanks for supporting.

u can do wateva the hell you want to it but if u dont get an ecu and tune the mods according to your car then they will all be useless. dont listen to the people who say "man i just threw on a nice header and my car feels way quicker than before" because in reality it makes no difference as the stock ecu cannot recognise the mod. If youre just on a 2k budget spend it on a nice set of coilovers/swaybar/strutbrace. OR save up a bit more than 2K n get a nice header, cat, exhaust, and KPRO.

not true. Bolt ons will increase HP, but only to a limit. To take it pass that limit, obviuosly you will need ECU. Stock ECU has learning curve, but can only learn up to a limit

yeh but that limit isnt very high lol especially with a car thats NA an exhaust will give u wat, 2kw?

intakes, headers, and exhuast, still give fairly good gains. I don't know the exact figures, but some cold air intake alone, have been dyno'd back to back from stock to give around 10kw extra.

get a gruppeM best mod by far mate! start wit that and coilovers..

your right bolt ons do give gains and you can't just say that they're immaterial coz the stock ecu is so dumb nothing will happen.

but an ECU is essential to take full advantage of any modifications

thanks for all kindly and useful advises above, what the hell is KPRO? sori but bit confuse.

stock ecu so dumb? nothing will happen? I don't think so. Honda ECU's from factory and perfectly tuned, and have a learning system that retains memorys, and input signals from different sensors, that all together effeiciently runs the car. obviousley having a after market ECU, you can full advantage of you mods, such as adjusting air fuel ratio's etc. but i wouldn't call the stock ECU dumb.

And its not peak power either......With NA cars that are small in displacement i think the emphasis should be on mid range power and torque production. Get the parts that do that moreso then top end....i mean 9/10 do you drive on a track most days of the week?
