anyone make a jcw spec I believe 11.4 % pully so I can remain in stock class?

My car is an 05 and I can convert to jcw pully/airbox/injectors/tune/diff/suspension.

A full jcw supercharger is "ok" too or if any rebuild services out there can rebuild mine and put on a jcw pully that would work better I think

also looking for jcw clutch type diff, and injectors & airbox


No I cannot run a 15 % pulley, it would place me in d-modified and I do not want to go up to that class where you can do full 250hp race builds

 

The "JCW" also had a lightly CNC ported head....so if you want to compete with real JCW cars....

 

not sure that's worth it to me right now, the heads are not cheap

 

I know....car will likely be more fun on the road with a pulley...
But most every aftermarket pulley is going to be held on with bolts with a collar style arrangement.....OEMs are heat set....so not sure if the car would pass technical inspection with a JCW pulley.
I remember hearing a few getting sold early on....so they might be around ....
But just tossing on the sc pulley, tune, intake, and exaust will not get you JCW performance...not exactly anyway...the head had the exaust ports ONLY if I recall CNC ported....but it made a difference....
Since the "vendors " here order their parts from a few makers, they might be able to get you a pulley on a semi custom basis ...
First place I would check with is Cravenspeed....they sell their own in-house made stuff themselves AND to other popular vendors ....so they would do it in house....heck they MIGHT have the CNC program already mapped....

 

Personally it sounds like you're going to spend a lot more money on JCW parts than you're going to get out of them. You can go aftermarket for all of that and make better power, cheaper.

And yes, I understand you don't want to fall into D-mod, but a slightly modded MINI will hold its own with cars twice its power just in its handling. There is also the question of; are you out there to be #1, or have fun?

To my knowledge nobody makes a JCW size aftermarket pulley.

 

@mega72, you may want to PM the OP from this thread to see if his pulley comes off clean or not.

you need to do a full conversion to be legal. also, the car has to be an 06

 

No 2005 had port JCW option I just bought a JCW engine swapping top soon

I think they had JCW suspension port option and 05 had factory LSD oprion

 

Yup, my early '05 (build 11/04) came with ported head, injectors, exhaust for the JCW Pkg and LSD & Springs for the Sport Pkg.
But that changed later in the year and they basically merged the packages, and I think added the brake upgrade option also.

 

was yours port installed? Any docs showing that? if you post it, it should be a sticky in the autocross forums

 

LSD wasn't a factory option (2TA) until January 2005.

JCW Package (Tuning Kit, Sport Brakes, LSD) wasn't a factory option (3AL) until November 2005.

Enter last 7 of VIN in Decoder to confirm.

 

rules allow factory OR port for the model year not by build date either

 

So dealer installed is not allowed?

 

for SCCA the model year + option available from factory OR port is good to go

for the early mini's they did not have a port option for jcw suspension or the engine package

 

My JCW package was dealer installed, with documentation, the LSD and Sport Springs (which my dealer called the "Sport" package) were from the factory.

 

dealer installed is not good enough, but if anyone got a port installed for the model year than you are good to go

I thought there were some port installed 05 JCW's but I might be mistaken, local club said all facelifts could upgrade, meaning 05-06

 

Hmm, wonder why dealer installed isn't good enough, the package was a factory option, but the factory hadn't upgraded the engines for the early production runs, therefore the packages were sent to the dealer to be installed prior to customer delivery.
At least that's the way mine was done.
If you like, I can check my bill of sale and order form (I think I still have them both) and see what the exact wording is.

 

weird scca rules, but I thought there were some port installed 05's and that makes all the 05's ok to have jcw engine kit

it's really dumb because the JCWs are all in the same class as the S now, very unfair to the early r53's

 

Absolutely, considering the injector and tuning upgrade post '04

 

if you guys have documentation this was port installed and you want to run your pre '06s converted to JCW legally in DS (or even STX) you need to submit it to the SCCA - right now, it's only '06s that are allowed. Until you do that, it doesn't matter.


Dealer installed is never allowed, unless it was legally port installed that model year, and the dealer happened to do it (same as any other shop installing port installed parts)

 

Sport Suspension Plus was standard on US MSC models. Supposedly LSD wasn't available until January 2005. What's the last 7 of VIN for your car?

 

TF81466, listed on the window sticker as a $1350.00 option for me.

 

Sorry but your car wasn't built with a LSD (option 2TA). Sport Package options are highlighted in yellow:

 

Then my bad, guess somehow the dealer did it then, I sure thought I remembered that the only thing they did was the JCW package upgrade. But maybe that's all I remembered because of having to wait on delivery for the package to arrive and be installed. Seems weird that an LSD would be a dealer add on but again, maybe like the JCW package, they just weren't ready for them at the factory that early in the model run. Probably won't matter for the OP's issues though.
And all that matters to me is that it's there....lol

 

Are you sure you have LSD? Seems like that would be very pricey to install later.
