Acura RSX Forum : “What's your goal with your RSX?”

Mine is my daily driver. Got the best deal for the best car in best condition. XD


basically, modify the airbox, exhaust and header from a Type R and a Hondata reflash.


I suggest to everyone get a reflash or kpro.

Daily driver with flair. A drop of about 1.5, pedals, CAI, shorty header exhaust, polyurethane motor mounts/bushings and a reflash. Add a stock trunk lid spoiler (not the Type R the factory RSX spoiler) Maybe a rear sway/strut and some JDM visors (are they visors?) on the doors.

Currently have cai, skunk2 exhaust... Im aiming for a stupidly fast sleeper rsx-s. Putting in kpro, bcrh, sways, and dropping it this summer so got some time before i start a peakboost build. But lookin for 400-500hp range eh who knows.

It'll be my DD till i pick up a cheap bike somewhere.

400-500?? What, you planning to toss out the KA20 and put in a Skyline engine or something>?>? XD

lol no need for an rb26... Ill go either peakboost build with gt30 or gt35 turbo.. or possibly stg2 full race kit eh not sure as of now. but yeah those arent extreme numbers..

^lololz they extreme for an RSX!

XD

that depends on what engine he has. if he has an 02-03 then he has the k20a2 and no those arent extreme at all actually very easily accomplished with a slight amount of money and a little time. if he has an 04-06 then he has the k20a3 and for that engine it would be more difficult but still not that hard to accomplish  just have to do a more exstensive build.

Umm mate - the RSX Type S has the K20A2 engine, the Base RSX has the K20A3. I think you refer to the K20Z1 on the Type S  from 2005 onwards.

And honestly, its very difficult to F.I. any Honda to those sort of numbers without spending like a mother. He would need a larger displacement - H22 or my personal fav. the K24A2.

An yeah im tlkn bout the k20a2.. and no not really. Your basic kit will spit numbers around 280-290? so no need for a swap.

Lololz, 280-290?? Even for bhp thats a faint strech... most likley dream numbers. The Type S and R, yes thats a strong possibility, but not on the base.

And swaps are not just about getting the big numbers... since we can never utilise high levels of boost without strengthen the tranny or replacing nearly all the internals, a larger engine would be a better choice for high power upgrades as far as getting things to work efficently. But I don't recommend it if you just want to boost, it will do the job in the end. The best reason to do a swap would be to avoid the induction route.

Didn't say the base could? I said basic kit as it your starter turbo kits. And the capabilities range 300-450+whp without a swap but yes many other parts other then the larger turbos for those numbers. And why would you want to avoid it? I personally preferred s/c but the power differences are incredible. Also those aren't dream numbers, talk to many of the turbo thread members. Their dyno sheets will prove otherwise.

A swap may make for more n/a bhp but FI & s/c actually increase engine efficiency by roughly 13%+

Well, im more of a practical guy... dont force induct a car which isn't meant to be forced. Honda's arent. XD

Dyno sheets are unreliable, they just good to show what kinda increase, gimmie 4 near consistent graphs then you have a good result. And it never really translate to on road performance.

I didn't think forced induction with make the engine 13% more efficent. But for hell sure it would make the engine heaps more unreliable and kill its longetivity. XD

With a good tune and the right maintenance, as well the correct mods to make the engine well equipped to handle the boost, it shouldn't destroy the life of the car. And for not being meant to turbo some ep3's sure put up some good #'s.

With enough boost and high enough octane fuel, you can make some good numbers with a lawnmower motor.  Doesn't make it reliable or practical in any stretch of the imagination.

And correct mods would be valve train upgrades and bottom end... in which case it really ain't the motor Honda built.   The motor is designed for 14.7 psi atmosphere... It don't take a whole lot of boost pressure to go way beyond what the motor was intended for.

Too each his own but that'll take a good deal of time and money...

I mean look at the basic numbers
------------
it's 11:1 stock on ~100 (R+M/2) the highest sustainable I've seen without pitting occurring on an engine is 14.2:1...  At 5 psi boost you're damaging the engine... well assuming you get the charge cool, so we'll say 7 psi in more real-life example.  And trust me at this point engine life is cut back severely... so if you maintain efficiency (Good luck boosting and keep a N/A's efficiency numbers) you can peak the motor at 295 horsepower (based on a 201 hp stock (which I believe is flywheel correct?).  But then again you'd be driving on 100 octane with 4,000 in the motor and you'd be lucky to get 75,000 out of it before a rebuild... And if your BOV sticks and you get a decent surge your engine could grenade...
----------

So it's possible, not necessarily practical but possible...  But then the cross over point for most these kits isn't till 5,500 RPM or higher (even on the charts the manufacturers give out)...  So if you want to keep your car strung upto 6000 RPM then it may be a good idea for you...

I'm laughing my ass of looking at some of these dyno charts kit manufacturers are showing...  When you see these numbers mate, look at who is giving them to you.

IMO
K20A2
Great engine

Turbo
Great power adder

K20A2+Turbo
An exercise in wasting money.  Unless the car is meant for a 1/4 mile life... Personally, I look at this as a track car/Sporty daily driver and should have better torque at the lower side of the mid range.

But that's my bias.

k pro ...... thank u for bringing that up talk about changing your car completely

k20 NOT ka20...someone doesnt know their motors

welll ive got a 2004 rsx coupe 5spd. I got a lot of plans for her within the next 5 years. I currently have the stock k20a3 motor in it with vtec and a nice intake on it. its all emptied out under the hood.
But...my plans are to fully gut  the interior for a nice black with red insert leather throughout. the carpet and ceiling would be covered in black. and id change out my short shifter for a stage 2 or stage 3 6spd clutch, which means id need a new tranny as well so as well as changing out the tranny for a 6spd...ill be taking out the whole motor, cleaning it, and selling it, so i can get an rsx type s motor and ill get rid of the intake and change it with a nice turbo.As well as changing up all my wiring and my sound system, with a custom built casing for the subs and amps in my trunk. (done by me) oooh and my exhaust needs to be changed, its just alil too loud for me, something quiet but ballsy is what im looking for, probably a magnaflow. Gotta fix my suspension to a more sport orientated one, as well as minor details for weight and the chassis. Minor details will be fixed throughout the whole project of this car. Im just really going over the basics and looking at prices for now.
My goal is to have a beautiful car that will push 450 to 500 horse power. with everything from under the hood to the interior and exterior of the car being touched by my hands, no bs mechanics to do all the work for me. This is a plan for the next 5 years. So when I am done paying it off itll be nice as fuck. :)

If you have any suggestions please let me know, Im still working on the details of the motor, whether or not i really wanna switch it.

400-500 arent extreme boost numbers. there was one in superstreet on a peakboost kit boosting 16 psi making 646whp. thats on stock internals. its definitely do-able but as far as reliability you'll be lucky if the motor lasts two years after that if you stay with stock internals

yeah i know 400 to 500 isnt much when throwing on a turbo...quite low if u think of it. but the fear i have IS blowing my engine. thats why i dont wanna add too much boost and i just wreck 3500 bucks. i am only playing around with the idea so far, but id def change everything within the engine so it can hold the turbo. I DO NOT know everything about cars, but i know enough ... especially for a chick lol.

keepin my 06 type s a k20z1 sleeper, just going to push it as far as i can all motor hoping to break into high 12's by the time im done/completely satisified. want to keep the outside mostly stock besides a mugen lip kit. I just want people to think it's stock with just an exhaust so they're sure they're shit on me but there in for a suprise. so far ive got Megan Racing headers with cat delete, Injen MR SRI, HKS HI-Power exhaust and a CT-Engineering (Comptech) Short Shift Kit with Strut King metal bushings. Planning on Skunk2 Cams, Skunk2 Valve Springs, JE Pistons, Brian Crower I Beam connecting rods

that wasnt to you lol
