could one swap a 02-04 cooper s trans with longer gears onto a 07+ cooper s.

longer gears = stay in boost longer
longer gears = potentialy better mpg (maybe)

less wheel spin
especially since im gonna try and get some 15x7
with 205/50/15's

this would be a great thing to have!

but is it possible

 

Quaife do a gear kit for the Getrag manual 6 speed, found in the 2007 + Cooper S, here is the link.

i believe this is opposite of what he wants, thats a close ratio gear box for track use.

besides i have driven dog box's on the street in subarus and its a major PITA.

its not worth the hassle or the money, back on topic i have no clue if those 2 transmissions will match up but its a cool idea for sure.

so i wonder if i can hybrid it???

i know when i did my gsr with type r swap
the type r trans was so short!
i was at like 3800-3900 at 80 on the freeway:/
so i ended up swap the regualr gsr 4th gear and ls 5th gear and got down to 2750 at around the same speed with only those 2 changed...worked wonders...


so i wonder if we can do the same here?
ill be running 15x7 (205/50/15 on my R56)

i wonder if those 2 swaps can be done?
the trans is coming out of my car for a fx400 and mini madness flywheel. and os giken 100% locking LSD

i just wonder if i can get longer gears to stay in boost longer and because ill be running 15's?

anyone if you have any knowledge plz help

 

also im reading that the 07+ getrag was weaker than the 02's?

everyone i see say the 02s are indestructible

would i be able to throw a 02 getrag 6 speed manual on the R56 engine?

i want longer gears for daily driving and to stay on boost longer...
also wouldnt mind a mpg bump lol

 

alright guys
this is what ive come up with as a comparison...with http://www.fatboyraceworks.com/gears/

BUT the nicect thing is you can compare on a graph with http://www.fatboyraceworks.com/gears/
how long each gear is...it shows you how line up with each other and all check it out very useful in my mind...
now if they are swapable is the next thing!
seems like the 02-04 cooper s transmission is what i want lol..
anyone know if its swapable?

 

Before you go any further, where do you get 7300 RPM redline from!

 

tuned

lol
made it more practicle because i wont be keep the stock redline once its tuned...
from what i was seeing theres more power to be had with the right mods past 6900!

i guess i could of gone like 7100rpm
but i see from posts alot of people tune to 7300.

 

Oh dear you seem to be confusing the tuning of the R56 N14/B16 engine with the R53 W11 engine, the two are worlds apart!
Would you care to share with us, your planned mods for your engine?

 

ya actually i did get the 7300 redline off the r53 lol
wrong move i guess?

and heres a mod list..


M7 aerogel heat shield
M7 ram2 hood scoop
M7 under strut system
M7 oil catch can
Helix FMIC
OS GIKEN sure lock LSD
Spec stage 2+ clutch
Mini Madness 14.5lb flywheel (i want the M7 flywheel but cant find it????)
Alta boost tubes (red for hot & blue for cold)
Alta 22mm rear sway bar
Alsta boost port adapter
Alta PSRS
Alta sway bar endlinks (front & rear)
Alta rear control arms (2 sets upper and lower)
Alta power pack #1 (Catback Exhaust, Cold air intake and Boost Gauge with Pod)
Alta PWI-2 meth injection (91 octane in cali:/ GAYY...so for weekends when i run hard...i can do it be safe lol)
Braille 15lb battery (how much does the stock battery weigh?)
BSH lower motor mount
Megan Racing coilover w/ adjustable camber plates
TCE Wilwood plus 1 brake kit (11.75" rotors, kits fit 15" wheels)
OBX downpipe
Riss Racing 02 simulator

RMW or Mynes tune
possibly a mildly built head when iget the quote on it today
and if i can get some feed back id like to run a 35-50 shot once in a while...


heres the thread i started trying to get some info on the R56

https://www.northamericanmotoring.co...-it-worth.html

 

Who maybe doing a cylinder head for you? and have you thought about the turbo too?
Nitrous is safe, if installed correctly! Have you been watching fast and furious by any chance?

 

no sir i cant stand it lol...ever since those movies came out everyone thinks there fast. (with a fart can and some stickers)

cayon racing came to me at 13.

i had a 94 integra gsr at 18 with a type r swap built by bubba at do-it-dyno...(recently stolen thats why i got a mini)
and i did some auto-x with it i just didnt like it! no one to race with just competing against the clock.

with canyon runs you get the thrill of having other cars with you in the same tight corners and then the fact of know theres a 100 foot drop just a few feet away...
its an adrenaline rush to me....and its done usually friday/saturday nights
my weeks are spent at school and work.:/

now a turbo swap is something id perfer not to do. until i have my car build for a while with full bolt ons and meth injection and maybe nos...


and the head would be build by thumper and he just got back to me on the price
$1600 for what i want! which is a decent price


ps: street racing isnt my thing lol...but come on every know and then everyones raced someone.

cayon racing is my hobby we dont street race through it lol we drive at our limits. no moneys involved just some friends looking for a good time...hopefully if my cars build i can take it out to the dragon next time everyone goes out there!


and ya i know if nos is installed corectly its safe my thing is like every car has its limits....
i know nos likes higher compression while boost doesnt!
so how i was thinking was the R56 has like 10:1 maybe a little more
for nos its good but would there be any bad side affects of doing it a fewtimes a week?
on a 50 shot i think id be alright but then again ive never had a turbo car so im lost?

and bubba at do-it-dyno would do the nitrous...he had me running a 125 shot safely on that type r swap and i sprayed like 5 or more times a week lol...a couple times from a dig!

 

I'm sure Thumper will do a good head for you, his work on the R53 heads has shown good results and should be just as good on the R56 head. Are you having larger valves and cams too?

 

right now just a mildly built head
inconel exhaust valves (cheap insurance if i spray)
black nitride coated intake valves
5 angel valve job

its basicly a TPR-2 head with standard sized valves
might go a little bigger on the exhaust side

cam is undecided i wanna find one like the NS1 cam just something mild.
i dont want to lose my mpg cause i drive like 250-300 miles a week sometimes more
to work and school
well the mods i have im sure id lose some
the head might gain me +1 or 2
if i run meth injection that might help a little and staying off boost is my plans...


and heres something to think about
since our stock turbo spools super quick and falls off up top.
couldnt i get a bigger cam with more up top power since the turbo takes care of the low end?

 

Generally Gen1 and Gen2 parts are in NO WAY interchangeable....the motors, etc are just so different....the GEN2 is no way an evolution of gen1...but a total clean sheet re-desgin, with the same shape.
When thinking of mods..it is best to forget all about your r53 readings, and start over. Since the torque is so different+at different rpm's....I doubt you would be happy with a r53 tranny in a r56...if you would have been happy...then the desginers would have kept using it....But on a serious note someone might start cutting r56 gears..helix has done some straight gears for a r53..kinda loud I think, but fast...PM them and ask if they have anything planed for gen2!

Imported from MINI Sport in England, one of the leading racing preparation shops, this king gear and pair of pinions loweres the final drive ratio of the Getrag 6 speed gearbox. It uses straight cut gears so the car is a little louder with that race-car whine. The result is very impressive on pre 2005 cars: the acceleration is ferocious, especially in the lowered gear. We installed this kit in a well-modified 2003 and the car is without a doubt the quickest non turbo car we have driven. The limiting factor is traction, not power. For more details on installation, and gear ratios, please call the shop.

They do lower the ratio..you want more acceleration right? If you want to go the other way...taller (only really do-able if you get more torque, but it will slow you down...not what most folks want...) I'm sure it can be done...but just change you tire size a bit...you will get the same result...but the speedo will not reflect it...

 

Your cylinder head build sounds good from the point of view of further future mods, many people think that when it comes to valve and port size, BIGGER is best, well on a turbo engine, this is just not true, you must remember the basic principal of exhaust gas velocity (speed) get this wrong, and the exhaust gases will expand too much allowing cool down and subsequently loose velocity (speed)
Having too large an intake port can have a similar effect on loses, large ports need more time to fill, and can result in turbo lag too!

As far as I am aware there is only the Schrick camshafts out there for the R56 N14/B16 engine.

A BIG camshaft/s is also thought by many to be the best, but in a turbo situation, BIG lift and overlap are not the best, IF you are looking for good throttle response and no or little turbo lag! however you will get good power increase at the very high end of the rev range, with BIG lift and overlap, however you will also suffer from very poor throttle response at the lower end of the rev range! Having this arrangement can also lead to compressor surge due to the exhaust gas velocity (speed).

 

i know the R53 and R56 parts arent interchangeable....
but gear wise they r both getrag trans lol
so i figured it be a possibility

i swaped the 4th gear out of a integra GSR and the 5th out of a integra LS into a type r trans

all have different trans lol and it worked great so i thought on the same concept
seems its a no go though
and im dead set on 15x7 205/50/15's shed quite a bit of weight and im into 15's i have no idea why but i think it looks good!


Razc:
i understand what your saying.
i figured it owuld be better to get maybe .5mm oversized at the most on the exhaust to help get the gases out and run a little cooler possibly?
and stand sized intakes (of course i dnt know much on heads so...)


and the other thing about cams is
with a quick spool turbo that falls off up top what should i do?
i was thinking maybe a cam with more power up top

so id have all the low end power from the turbo and more top end cause the cam? would the concept work?

also im looking at downpipes right now....what size should i go with
2.5" right
i figured a 3" alta downpipe would cause slower spool because how big it is?
im gonna have the alta 3" catback but no sure on the downpipe?

 

.5mm oversize exhaust valves, is there room for this increase? More importantly what are you going to gain from this size increase! with the stock turbo......nothing you will feel or see on the dyno, the exhaust valves are already at there optimum size of 26mm for the given cylinder displacement of 399.5cc
Have a look at the profiles of the Schrick camshafts, and with your cylinder head man (Thumper) discuss your needs against driveability! or read my post again.
With the stock turbo all you need is 2.5 inch (63.5mm) diameter, as 3 inch is way too BIG, remember exhaust gas velocity (expansion) cool exhaust gas = slow velocity (speed)!

 

alright ill post again if i got any more details
