im doing this project in my car im new with minis i would like to know a good programable ecu for my r53

 

Stock, and drop one of the 2 boost devices.

 

Stock ecu????? And what u mean by taking one of the two devices ??

 

He means stick with the stock ECU, and only run one boost device IE: Supercharger or Turbo.

The stock ECU can be competely cracked open with ByteTroniK FA so that you can tune it yourself.

 

Sow how much can i get off a supercharger?? Can i get at least 300 hp?? Or u recommend me to go turbo instead ??

 

Btw thanks for the info raze i didnt know about that byte tronik

 

I think he means, yes stock ECU and choose one of the options out there for tuning that ECU, and from your title you're talking about twin charging, and while yes it's been done in order to do it right you have to invest about the same amount of money and probably considerably more time into getting it right as opposed to just doing a much simpler turbo only conversion, which will give you better yeild if you want it to. (twincharging will have an inevitable hp limitation simply due to the configuration of the system that turbo only won't)

Basiclly pick a hp goal and that will give you a direction.

 

For the Simplest HP gain outhere that will net you the most HP i would go with a custom single turbo build. Superchargers will net alot of HP but i have seen more high HP turbo builds then the later. not saything that they are not out there, there is just more HP with a well build turbo setup.

 

SO TURBO IS WHAT IS IS THEN I KNOW I NEED A TURBO MANIFOLD BUT IF I TAKE THE SUPER CHARGER OUT IM GOING TO NEED A CUSTOM TRHOTTLE BODY right????

 

cross posting

 

At this time on avg. 300whp is your dividing line S/C / Turbo, to do a turbo set up right You'll first have to get into the motor simply because of boost levels, then your talking about, manifold, fmic, and custom exhaust & piping, it's all available but be ready to drop $15,000 or so by the time your finished.

 

with 15,000 ill buy another mini cooper wtf??? if is like that im gonna sell it and go back to subarus lol

 

What are you trying to do with the car? The few people that i have seen do a turbo conversion spent a lot of money doing it and the results were nothing major. We don't have the luxury of a 2.5 liter engine like Subaru has so to get those numbers you will have to pay.

 

like i said before all i want is 300 to 320 hp i cant be that hard with a turbo system and a good dyno tunning

 

Check over at minitorque.com but I have to agree with BlwnAway, you are looking to dump some serious money to get it done, especially a conversion. It will all be custom.

The guys at MT have pulled some great numbers with an R53 and can give you great no BS advice before you start dropping cash. Most have been down this road already.

 

thanks for the help ill check what they say

 

I guess we are talking a r53? What year?
Just for a reality check, what have you done so far?

 

when you say all you want is 300 horse

thats some serious money still to double this cars power

well over 5 grand

 

i got the money man that no problem i just trying to figure out whats the best option

 

Just throw a Sprintex on and some supporting mods/tuning. That will net you some good power and it's alot easier. Then if that's not enough for you, you could always take it further. I could be wrong here but I feel that you are under estimating what 300 HP will feel like in a MINI. Even just in the low 200's feels very quick in our cars.

 

I'd wait on Sprintex until they figure out why it is popping engines.

 

You could also go the Rotrex route. That would be good for 300HP, mostly on the top end just like doing turbo, but without the lag.

There are options to get the power you want, you just need to make some desisions. Any way you go though, it's going to be way more expensive than making 300HP with a Subie.

 

Alright you've got me there.

 

where can u buy that rotrex at??? i cant find it

 

i either wanna go twin charged or turbo i heard that sprintex doesnt make alot of difference
