Another thing I plan on doing is going to specialist components and picking up their plug and play ecu kit and also their 50mm SPI throttle body kit, just so that I won't be restricted by the rover MEMS system, which Sprocket has got 100bhp out of but anything more will require a standalone.

Let me know how you get one, I've thought about doing the same as mine is definitely restricted by the MEMS.

50mm won't suit your application and SC will deter you from having it.

45 or 50mm, depends when I phone them up and what they recommend because I do plan on adding a turbo to the car down the line, when i'm no longer a somewhat broke uni student lol.

You'll need to talk to them as it'll depend on the rest of your engine spec. Too large a throttle body and its detrimental to power.

ahh I see, i wouldn't be spending that much money without a good chat beforehand anyway so we're all good.

Hi,
 
My Mayfair's engine has been rebuilt and rebored to 1293cc, had a stage 4 head, kent 274 cam and an LCB/RC40 exhaust system and K+N air filter.  Now has 53bhp at the wheels.  Still has the spi system.  Its built for reliability, could get way more power with a carb but the rolling road guy (Southam mini centre) commented on what a strong and well balanced engine it is.  I'd suggest going for the exhaust and an air filter to give an instant boost and it will sound nicer too.

Hi! Thank you for your reply :) youve certainly had some work then, bet it drives lovely, if you dont mind me asking, is it expensive the work youve have had done? 53bhp doesn't sound a lot does it but in a mini bet it pulls! Wheres a good place to get an exhaust system? I have a k&n air filter :)

 

Thats at the wheels, its 70 ish at the flywheel.  In total it came to under £2k which was fully built which I know is a bargain, the garage that did it isn't around anymore.  I supplied the head from a guy I found on ebay who builds them in his spare time but even with that, I got it within the £2k.  Id recommend minispares, my whole system is RC40 including the Playmini style stainless backbox.

 

 

wow thats a good price!! you got lucky there
