I'm considering a 09 JCW are bigger turbos or other hopups available?

 

There are quite a few threads about this on the first page of the R56 Cooper S sub-forum.

 

One issue that is important to keep in mind.
Turbo's are classed by their size and output.
A Garrett GT2860R and a GT3071R are both midframe turbos.
The 2860 has a different mounting hole pattern the the 3071.
When you look for a turbo replacement make sure it will fit or interchange with the exsisting hardware.

 

You will not need a bigger turbo. Just get a tune and a helix intercooler and the car will kick as-phalt

 

Test drove a 2011 R56 turbo car for the first time, and wasn't all that impressed. It was more refined, but had less MINIness(?) than my 03 R53 JCW .They had a 09 JCW but with summer tires I should have drove but didn't, I'm sure it would have been different than the 2011 (with more MINIness?). But by how much?

 

Why not go bigger? The JCW has better internals for big boost. Someone has to be getting more than 250whp with upgraded turbo....and I am talking real whp.

 

Alta's billet turbo, though sold out, is supposed to put out more power than the JCW's turbo. Question is, how much whp are you trying to end up with? I believe someone has already reached 250 whp with the JCW turbo. Alta's off the shelf stage 1 JCW tune supposedly puts out ~220 whp(according to their dyno graph) on a bone stock fJCW. 250 whp can't be that far away(even without upgrading the turbo)

 

The factory JCW is already running at 19psi versus 13psi for the S...

 

So? Why not run 28psi in JCW?

 

False. The Factory JCW internals for the N14 engine are identical.

 

So MINI was using false advertising saying its upgraded?

 

I believe JCW have 10:1 CR and the normal S has 10.5:1 CR

 

No you are incorrect.

The pistons and rings in the JCW are different from the stock S.

Part number for JCW piston is 11257576973 part number for stock S is 11257566019.

The JCW piston is 10.0 compression, S is 10.5.

ALL other engine parts are the same, rods and bottom end, head, including all valvetrain parts etc.

You should do more research.

 

Sure, just probably not for long...

 

No, the head may look the same but it a slightly different alloy for better strength.

 

Ignitionmodule He quoted facts and you say to more research. Do you have facts to say otherwise?

 

Fact?

 

From the original MINI press release.

On Motoringfile

NOTE: All of the quoted figures are in metric units...

 

hah. thats about EXACTLY what i thought when i did the same thing. test drove a jcw R56, went back to the jcw R53!

 

very neat reading

anyone else notice the Challenge Mini is 1 HP less than the JCW?! lol

 

My guess is what you're experiencing is the difference between a supercharged engine and a turbocharged one. While the BMW folks have done a lot of work to minimize turbo lag, I suspect there is still a bit. Also, the torque curve may have a slightly different shape between the two.

 

Funny, I did the same thing as you but swap the cars. R53 was a friends, and a blast but I found it lacking in comparison overall.

 

i thought the turbo version was "soft". the engine wasnt loud at all, and there was slight turbo lag, not a lot, but it was there. i guess i didnt really care as much for the power curve either; felt too "normalized".

i also feel the R53 interior looks cleaner, more stylish; R56 has too much going on or something. it loses the "cockpit" look.

lastly, that R56 was over $10k more than the R53 i found!

 

He quoted one fact and followed up with hearsay that could easily have been corrected using Google or a forum search.
