A good old fashioned service does wonders ....... oil and filter change ( 20/50 oil ) plugs points , condensor , set of leads , check/adjust valve clearances and a tune up.
After that the only way to go is a Minspares stage 1 kit . Will need a tune up at Geralds after that .
Then a decent head .
Then a cam etc etc .
Minis have been tuned in this order for years and years .
If you got the head already it doesnt really matter , still do the other stuff . Read up on rockers tho , there are pros and cons .
Read what keith Calver and AC Dodd think .
AC is a really friendly chap and will tell you whats what in plain english . He has been down to a club meet in the past , very very clever chap .

Whats your budget and what application? Most normal tweaks starts from £400 and sensibly ends well into four figures...  And then brakes and suspension will need attention to meet the requirements to handle a faster car. I assume you have a 1275cc. This is the cheapest form of 'power' from a mini. If you have a 998 and want more, change the engine if you want value for money. I love thrashing my 'stage 1' 998 with 55bhp but I could of spent the same on a more powerful 1275 for 65bhp! The next level of tuning is a service and high maintenance of your car. Thats everything in good order. Fuel, ignition, valve seats. Everything you can do from a Haynes manual. Budget £100. Don't knock this, taking your head off, cleaning and lapping in your valves, refit with a new gasket, perfect ignition and fueling will improve the performance back to factory performance. That should be 55 to 65 bhp on a 1275. Next from that... is a stage one tuning kit from minispares £200. Not the cheapest but by reputation and results, the better for your cash. After any modification to the engine from standard, should be a tuning session. Gerald Dale in Ninfield is closest and a budget option. If your willing to pay more and travel further, ML Motor sport with the Guru AC Dodd in Kent would be my recommendation. £150 + travel. That will get most 1275's up to 75 BHP (Ponies of pulling power defined as Brake Horse Power). That should give you a very reliable and 'powerful' mini. You may easily spend £600 just to get to this stage. So after that for every pound you spend you get less of a return for power. So many options, head, cam shaft, carb, capacity increase (1293,1340,1380,1430 etc) turbo and super chargers. The full works would setup you back £9000 for 200bhp. But a sensible 100bhp 1380cc with a stage 3 head and sw5 camshaft is within reach of £3500 with some DIY. So what first, get a health check. Book in to Gerald Dale for a rolling road run and diagnostic check but not tuning unless you want to spend a full £120. (mention your from EDMC for a discount). Define that you want to know what is 'wrong' or lacking in your engine. Then you can decide to save for a new engine or pursue tweaking your current. Don't splash out of heads and rockers off ebay just yet. Assume only crap is sold on ebay. Those items if going for cheap will be worn and performance less than the same money throw at your car for a new distributor or carb rebuild. Sorry its a war and peace post, but this subject fills libraries at motor mecca and what I've said only covers the mini 'basics'. So what are your thoughts? |

Basically its what I have got and done to the mark 1. Spoke to AC and Gerald Got stage 1 kit , bigger valve head and MED cam . The head and cam are nothing wild or expensive its just built on a 1340cc block instead of a 1275 one . Still got a standard gearbox , although with a AC Dodd recommended diff ratio and uprated diff pin . |

right i think i write it down as it was alot to take in right, you told me you had 998cc, stage one kit, you have it set up at geralds not so long ago but it still too low for you and lugs on hills. your gearbox is good and has disc brakes. few option like the ones above. keep your engine or swap for a bigger one, if you keep you engine 1.as dave said,a good service will be the first thing, get the parts at shows if you can they are normal cheaper 2. a decent head stage 2/3, dont rush a buy any old head as you dont know what its like, look in to it first shop around, to buy a 998 stage 3 head will be about £300-£400 for a decent one, you can get budget ones cheaper 3, a set of 1.5 rockers, they say on a 998 it like putting a cam in, with out having to strip the engine down www.minispares.com/Product.aspx?ty=pb&pid=34870&title=ROCKER%20ASSEMBLY%201.5%20HI%20LI... ( dont do a cam and a set of rockers on a 998 as it gives it too much lift) other that that, rebuild and rebore etc, to do it right £1000+ if you go for a bigger engine best option is a 1275 A plus or one that has been bored, be carefull people do sell alot of crap, claim it has more power,etc. best to see it running and test drive it before you buy if you can prices can vary, depends what its had done to it and how many miles its done, do you throw more money into your 998 or do an engine change.  ?? the choice is yours!!!!!!!!!!!!! |
