hi guys !
i am considering about buyin a GP on these days but i have some questions on my mind... i have lots of modifcations on my R53 like alta pulleys (%17sc, %2 crank and altanator), alta top mount intercooler, alta cold air intake kit an hamann headers and one ball exhaust system. I love my car and i can only sell it for a GP !!!
I would like to ask you, what are the differences in the engine of GP. I know ECU is re-mapped and a bigger intercooler is sleeping under the hood... and what else ???
if i will buy a gp, can i modify it ? can i use a smaller pulley for example ? or can i use my alta intercooler and air intake on GP..
how far can we go on the GP ??

Thanks a lot

Can.

 

You have a Hamann header?

I would gladly take that off your hands

 

Sacrilege! Don't buy a limited edition MINI just to spoil its rare integrity!

Yes, you can mod a GP in exactly the same way you can modify any other R53. The question is whether you should!

 

why you said so ?

 

I wouldn't mind modifying a GP, it's not as if their are that hard to come by in anycase. Do what ever makes you happy! Good luck!

 

Oh, I totally understand that each GP owner is free to do as they please with their MINI... and I don't pretend that there's any "law" or other control against modding it...

It's just a personal perspective. I believe that truly limited edition cars (and 2,000 worldwide certainly counts, IMO), regardless of brand or model, shouldn't be modified. It just takes away some of that "specialness", that's all.

Personally, if someone is that serious about modding an R53, why not just buy a no-option base R53, strip everything they can off of it, then mod the heck out of it? They'd be starting from at least a $10,000 savings over buying a GP, and that pays for a lot of stuff!

 

I paid sticker for mine

 

Your's has a few mods, but you have to keep the stock parts for down the road. May be worth some cash year's from now.

 

That's not what I meant at all. Totally understand what you mean. I'm just saying, a GP is a lot easier to come by than most "limited edition" cars. So that wouldn't be the most of my worries at this point, perhaps 5-10 years down the line it will have far better collectors value in stock form.

I would do the same of what you mentioned as well. Get a standard R53 and strip it out so it can be basically on par with a GP spec-wise. Would work out a lot cheaper as well.

 

I say go for it! The car was designed for purpose and why not enjoy it, life is to short to not drive what you want!

 

One more vote for keeping the GP stock.

 

Hey Jonnie

Stop it. You seemed to like my mods.

 

What are the differences between S and GP
ECU+Exhaust System+CAI and bigger intercooler.. these are differences that i know,is there any other thing that i miss ??

 

Lower aero kit, brakes, rear wing, no rear seats, no rear wiper and on and on.

 

Well, bear in mind that the exhaust and CAI of the GP are 100% identical to the regular 1st gen JCW tuning kit. They are not "unique" to the GP.

Unique to the GP (beyond an R53 JCW)... I hope I don't miss any:

• Larger intercooler
• Special GP-specific ECU tune (218bhp, up from 207bhp of regular JCW), with 7,000 rpm redline
• R107 wheels (lightest OEM 18" wheel that MINI makes... also lighter than all of the OEM 17" wheels)
• Aluminum rear control arms (note: the R56 has them too)
• Unique aero kit
• Thunder Blue paint
• Carbon Fiber rear spoiler, integrated into unique rear deck (no rear wiper, brake light relocated into lower window)
• Various GP badging (including unique production number on roof and on dash plaque)
• Cargo bar in rear interior (note: does not provide any structural integrity)
• Instrument gauges in anthracite
• GP-specific seats (not in USA versions)
• Sound deadening removed (weight reduction)
• Rear seats removed (weight reduction)
• Rear speakers removed (weight reduction)

Hmmm... did I miss anything, GP owners? I probably did...

 

thanx for the info
i am not interested with exterior differences so much, they are easy to see from outside too
the important thing for me is the engine i think this car will be a monster with some special touchs like pulley, headers, larger intercooler and maybe a coil pack
doesnt it ?

 

I'm pretty sure you missed the rear strut...

But if you do buy a GP Cosmicboy and want to part with your wing, I call first dibs and will pay good money for it.

 

Huh?If not this ^^^, what else were you referring to? The GP has the exact same rear strut brace as a regular R53. Did you mean the bar across the back on the interior? OK, I missed that... but it doesn't offer any structural rigidity, so I don't think it counts as a rear strut anything.

 

Oh my friend got a hold of one of them and he said it was a rear strut bar.. he might be mistaken. I just know a few of my friend have put a bar right there in their Integras and such.


that bar behind the seats is what i'm referring to.

 

i heard that the supercharger pulley used in GP is %14.6 or %15 smaller than sotck r53.. is that right ? if it is, there is no need to use supercharger pulley..

 

Slap on a 17% :D

 

No it is the same as a regular JCW = 11.XX% (depending on who does the measuring )

 

Some of my friends have problems with GP, has anybody lived an exhaust problem or a shaft problem ??? They also said that sometimes engine check light came on and they had to go to the service for turning it off... :(
do you have an idead about these problems guys ?

 

The GP uses the JCW exhaust. I have not seen any posts on problems with the GP's JCW exhaust. I am not sure what they might be referring to as a shaft problem. I do not know of any problem with any shafts on the GP or Minis in general. The only problems I have had with my GP is a leaking thermostat housing and leaking engine mount. Both were fixed under warranty. Both of these problems are common to all Mini Copper S.

 

That bar does not provide any structural integrity, so it does not qualify as a rear strut bar. It is just a luggage bar, and I believe the clip on it is intended for a baby seat or something (yes, I know... seems strange to put a baby seat in a GP. I might be wrong, but I do recall hearing about that's what the clip was for).
