well im going to bed now lol ive got school in the morning but you all have really helped. i think ive got a rought idea of what im going to change. could some one list the deffenate changes and the the not major things that ned changing . im taking the mick realy lol. o and another thing the gear box ????

[oli8925]

yep im going to bed too, and southy knows a lot more than me so im gonna leave it to him

night all

[Southy]

Deffinate changes which i would do:
Oil Pump
Big ends and main shells replaced (if the crank isnt marked otherwise regrind is needed)
New simplex timing chain and tensioner or upgrade for a dulex item.
If there is no lip on top of the bore i would get the block glazed buster and fit new rings to your pistons.
New gaskets of course

Things which might be needed:
Rebore the block to next size and buy pistons to suit.
Crank reground with set of shells to match.

Regarding the gearbox there might not be any major problems with it, but i would be tempted to strip the diff out and replace the diff pin for a new one of an uprated item.

And on that note im off to bed up at 7 for work

Budget on £500 for a complete rebuild if you are doing it yourself, first thing is would suggest however is strip the engine completely, bag and lable the nuts and bolts as you take them off..

Get the engine block professionally dipped and cleaned, this should be oil gallery plugs and core plugs out, there's not much point rebuilding an engine with all new parts with the block is still full of old grot and grime....

what is glazed buster???

[Southy]

Its supposed to be glazed busted sorry, basically its a process where you have a quick clean up of the bores with the honing machine if there is very little wear in them for the new piston rings to bed into.

[Jammy]

New pistons (with rings) - £150
Having a block rebored and new cam bearings - £120-140
Mains and big end bearings - £40
New cam followers and pushrods - £60
New oil pump - £20
New water pump - £25
All roller needle bearings (little ones in gearbox) - £25
If you need a new double roller in the gearbox - £55
Gaskets - £15
Shims - £15-30
Oil filter - £10
Air filter - £10-30
Possible carb rebuild kit - £30-70

Worthwhile upgrades:
Central oil pickup - £25
Hardened diff pin - £15


Budget for £500 if you're keeping your pistons and only getting the block honed, budget £700-800 if your getting an overbore. That's just to rebuild a standard engine.

[CharlieBrown]

Just a thought, why dont you just buy a running second hand engine for £100 and fit that? It would get you going for cheaper, unless you are looking to learn about rebuilding an engine.

[oli8925]

id still try to run your current engine without taking it apart first. people find things in barns, not touched for 30 years, stick some petrol in and drive it off. worth a try surely. or do what C.B. said, 998's are generally quite cheap on ebay, and i might be selling mine at some time (possibly soon, possibly not at all). if you want to rebuild an engine you could buy a runner AND take yours apart without the pressure of getting it running and back in in a certain amount of time. lots of possibilities

[sazal]

Ive had my engine rebuilt and bought these:

Clutch kit
Piston rings
2 inlet valves
2 ex. valves
Mains
Thrusts
Head gasket kit
Sump kit
Kelvar bypass hose
plugs
upper and lower balljoint kits
front indicators

And it cost me £270

Also had my head skimmed which cost me about £50

how much are you going ti be sellling you engine for oli ???

[oli8925]

how much are you going ti be sellling you engine for oli ???

god knows. its still a long way from being rebuilt tho, the way my times going at the moment. damned christmas and i need to find out what the gearbox is like. i might well be keeping it tho so dont bank on me selling it. im getting another mini tomorrow but dont know how the engine runs, so if its a bit clapped ill put my rebuilt engine in there as i know it runs sweet already, and rebuild and sell, or just sell the engine currently in this mini...if all that makes sense.

[JoneseyBoy]

lol ok mate. i should be picking my engine up to night but i fink im gunna see how much money i can get hold of because i might do a full rebuild to it because my old man said i can have his little bannger if i dont finish this project in a tear lol. do you think ill get this done in a year. well im going to try im up for the challenge lol

just the engine rebuild? yeah easily do that within a year. if you have the time (and money) you can easily do it in a week. a full mini rebuild can be done in a year too, but obviously the more you have to do the harder it will be to get it done in time, and youll always find more than you bargained for!
