Why not save your money and buy a cooper s?

 

That's a lot of cash to blow on an R50. The early R50 JCWs with the polished head, exhaust and air filter were only 132bhp. You'll be laying out big chunks chasing small gains.

As above... R53 Cooper S, Catback and a pulley will see you near the 200hp mark.

 

You can reach 145hp easily, after that it gets harder. If you keep spending, you will max it out at around 185-190hp. Talking by experience

For exhaust manifold, i highly recomend this for you : http://www.minitorque.com/forum/f229/piper-jcm-4-2-1-exhaust-manifold-99842/

 

Thanks is just i wanted to build one not buy one

Cheaper to convert it to a Cooper S, thats what I've done. Donor car cost me 1100, work about 500. Insurance for it with other modifications is only £450 a year for me.

 

Im just gunna do the same mods but with a cooper s

Were does the cooper s top out power wise .how much can the internals take

With a few basic modifications based on my old car; 17% pulley, GRS intercooler, OBX manifold and catback needed me 220 bhp with the stock airbox. The same car when Ben owned it before me made 280 bhp with the above but with am RMW big valve head, RMW cam and 440c injectors and tune. The R53's internals will take 280 ish without any hassle for years. The R50 wont.

 

Ok i was hoping around the 300 bhp mark as im planning to install a ported and polished head
Highlift cam
Milteck 4-1
Catback
Individual throttle bodys
19% pulley reduction
Intercooler
1000 cc injectors
High pressure fuel pump
And the list goes on

You won't get anywhere near 300 with that set up. 270hp if it's healthy.

Sprintex will make 300+ on that spec with a reduced pulley.. but it's a lot of cash.

 

What would i need then

Dude, you will need to spend about 10 grand all in all. You're only 17-18. Either buy a Cooper S, or drop some nice wheels and coilovers on your R50.

 

Cooper engine wont take anywhere near 200 in stock form. Cooper S engine will make 280 without too much work. For ITB's alone the cost would be 6k as you will need to rebuild the engine and fit a standalone ECU to run them, I know a couple of MINI's that have and the cost was much closer to 15k in the end for the engine and it was more along the lines of 250 bhp but they were build for FIA hillclimbs where the classes didn't allow for supercharging as otherwise they would have stayed S/C'd.

 

Didn't see the ITB bit, LOL.

 

1000 cc injectors would be overkill as well

 

Id have a fuel presure regulator so on the tune it could be put to whatever is needed

You don't even need 1000cc to run double the power you want out of a MINI...

 

It's all talk anyway mate. Loads of threads around like this.

Boring.

 

A thread that has a lot of talk and not a lotta results... Hmmm why does that sound familiar.

OH WAIT!

:lol::lol:

 

Starts to be entertaining. Can't wait to see this build

 

Hmm ITB's and S/C..

 

Jake and guy right now...
