So i have a 05 r53 and want to know what mods to add on to get me hp like a r53 jcw and r56. I currently have 15% pulley, one ball mod, Alta cai and cold spark plugs (jcw). Dont want to go to crazy b/c i live in ca. And smog is strict.
What hp are people getting with what mods? Thanks

 

You're basiclly about there already, the JCW head and exhaust while slightly better aren't much more of an improvement in hp over the extra boost you're getting from using a 15% pulley instead of the 13% JCW pulley.

Add a custom tune and the 380cc JCW injectors to what you have and you will surpass a factory JCW car in hp.

 

I completely agree with BlwnAway. Injectors and tune are a must if you want a significant increase in hp.

I've also got a 2005 MCS with the following mods: Alta CAI, Alta 19% SC pulley, Alta 0% lightened crank pulley, NGK Iridium plugs, MSD ignition, magnecor wires, Alta Intercooler, Milltek full stainless exhaust.

I Dyno'd my car in April and found that with all those mods, I'm only getting 178hp to the wheels. Granted, I do have 130,000 miles on it, but still.......only 15hp increase from stock.

With a tune and some injectors, I foresee 200hp easily. However, am I going to race my car? No. So I don't see spending $1,000 or more to gain 22hp. I like my car where it is right now and enjoy the ***** out of it daily.

 

Like most have said, I think most R53 owners do similar mods for a daily driver:

Pulley
Plugs
Intake
Exhaust
Injectors
Tune

Depending on how much you really want, an RMW cam wouldn't be bad and fairly affordable. But if you want to make sure your car can still be driven without a tune, get some JCW 380cc injectors as mentioned.

Plus you have Jan in the same state as you correct? Get the injectors, hit up RMW and have Jan do his thing... Used JCW's and a tune should run somewhere in the range of 600, but from what I researched, it also fixes things like the small yoyo effect, the delay in the drive by wire, and in some cases, better overall mpg.

 

When you get injectors, and atune YOU MAY ALMOST MATCH A JCW, but the tq curve is very different...
depending on your driving style, you may consider a cam....this will increase higher end hp, but can hurt the lowend a bit...a mild street cam will idle normally...an agressive cam may "lope"...but rememner cam, then tune, and the 380's are imo a bit small for a camed car.
Living in ca, octane in your fuel is limited...so if you pick up a good gp intercooler, it willhelphegate the extra heat from the pulley, and help prevent the computer from pulling timing due to intake temps....

 

Looks like I will be saving for 380 injectors and a tune. Trying to stay away from any big engine changes i.e. Cams/headers b/c of the smog law and the fact that my mini has over 103,000 miles on it. This is my daily driver so dont want to go to crazy.

Another question....
05-06 r53 = 168hp
07-up r56 = 172hp
A difference of less than 5hp!!! Why is the 2gen faster and some compare its speed to a r53 jcw. Just by adding a cai to a r53 should make it faster than a r56, right? I know the 2gen has a 6th gear but that shoild only come in to play at higher speeds. What am i missing here?

 

Maybe Jan will come to the bay area for a tuning party!!

 

People buy hp, but "drive tq".
The place where the hp and tq is delivered is important (rpm's)....and gen1 has 6 gears too!!
Tuning the auto is very hard....and it does slow the car down (the speed of the auto).
You will likely be 10 hp or so less than a JCW of the same year...the 05+ jcws were 210hp.....
talk to jan before you install the injectors....the 380's in my case were the limiting factor...and a tune, as are injectors are all "major" changes as far as emissions...but like the cam, very hard to catch if done right...just like the oem gp intercooler. Oem look...so no flags.

 

I have an 05 MCSa with alot of mods including Jan's tune and 380 injector (I took the 550 out the car run better on 380's) I have 220HP and 194TQ. By the way I live in Calif. and I passed smog.

 

Stock for stock, an R56 will blow away an R53...JCW or not.

Reason is the torque....they have boatloads more. Stock R56 S's sometimes put down 190-200 ft-lbs to the wheels. You need usually head/cam/header/inj/tune to get that amount of torque in a R53. Granted...200 ft-lbs in an R53 is completely different than 200 ft-lbs in an R56. The R56 is all down low, and falls quickly...whereas the R53 is pretty near flat...hence why they keep pulling all the way to the redline.

 

Please give me a list of your mods .

1st & 2nd gen has the same 1/4 mile time?

Or

your telling me a r53 jcw is slower than a stock r56?

None of this makes sense

 

In my experience, yes. Maybe my post was a bit dramatic...it won't "blow it away" but they (stock R56's) are quicker then R53 JCW's. As I explained...they have a bunch more torque

 

if this happens I am in

 

I beg to differ with you. Their performance is rather identical. The R56 just feels faster because of that low end torque:

Motor Trend test results:

2005 MCS: 0-60 in 6.4, 1/4 mile in 14.8 @ 95.2
2007 MCS: 0-60 in 6.4, 1/4 mile in 15.0 @ 91.4

In the real world that's a tie!

Maybe mine was strong then lol (it wasn't actually...) I could always pull away from my friends R53 JCW.

Not really worth the debate though...like my GP better anyways

 

Maybe a tie between two NEW cars....
but the r53 now has 75,000 miles on average.....or more...so things wear....compression drops, sc wears, etc....
i still love my r53...simplely a better drivets car imo. Not trying to start a who is better war, just know they are different.

 

no offense, but your buddy doesnt know how to drive

and, even mathematically, the r56's, stock S models have 40 HP LESS than a JCW. So, having a JCW, i will have to formally Disagree with your statements!

 

Oyyy....sorry for de-railing the OP's thread so much, but I will say this....

Stock R53 JCW's will put out ~180-185whp depending on dyno...with a much lower torque #.

Stock R56 S's will put out ~165-170whp depending on dyno....with some having nearly ~200 ft-lbs to the wheels. The motor's output is underrated from the factory.

So....this brings you to only a 10-20hp difference. Then factor in the huge torque difference, an R56 will get a big jump off the line and by the time the R53's extra few hp take into effect, the R56 is already ahead and the 53 can't catch up, unless you are getting into higher speeds...then yes, HP will win slightly.

Trust me here...I've seen it with my own eyes many times.

 

Wait, you are telling me a r56 whp is 165-170 but it's bhp is 176. That does not sound right. R53 jcw loses 20-25 from bhp but r56 only 5-10?

 

That is what I said isn't it?

Mine was 163whp stock, and it was never a strong one. You have to understand that factory HP numbers are all marketing. The R56's numbers are proved to be underrated from the factory. We are splitting hairs here, I was merely stating my first hand experience between the two cars and why the R56 is generally a little quicker. Torque wins races....horsepower sells cars.

To answer your original question and get the thread back on track, you already have the mods to match the HP of a R53 JCW. If you want more, get a cam, header, and tune.

 

Here's my R53 Works car, just to toss a little data out here...



Cheers,

Thx Charlie

 

Just remember, the more tourqe a car has, the more fun in general it is to drive. That is why a diesel car can be so fun, but have low top speed (mostly due to gearing and the limited rpms of the motor, and low hp)....

Just think about this one...
a typical 80,000 lb tractor trailer truck has a little as 360 hp, but as much as 1500 lb foot lbs of tourqe from a 13 liter motor.......and usually 10 gears to get to 65 mph....heck the first 6 only get the truck to 15 mph!!
Pure hp never tells the whole story till you know about tq. Heck that tq is abalable at just 1100 rpm!! And its will typically never go above 1500 rpm is the driver is any good.
