The Block!!

Well this is my 1985 Austin Mini metro 99h B88 block.




Horrid Colour. This is the bottom end will remain fairly standard.









If you see anything out the normal let me know please.

This is the new rocker cover.



Thanks

your really going to build a road car engine out of a grasser engine that has been ragged round a field at 8000 RPM for a year?

good so see you have gotten back in the mood
as above, if you are hard for cash then it may get you buy id check the engine out thoroughly
i see you are looking at a front rad what type of front end do you have clubby or round? the golf rads fit nicely in clubbs pics in build log

Why not reuse the block ?
1060 is a +.080 bore and I think the grasstrackers are restricted to +.020 or +.040 so it should be good.

Metric is for people who can't do fractions.

Used to be +60 in NASA autograss

This engine is STD size bores. Ill get pictures of all the bearings and crank today and show you its been looked after amazingly

I have a stack of spare parts for 998's having broke 3 engines up now

its more cranks and rods and rods bolts that are issues in autograss and ministox due to revs they suffer...l

This is state of the crank and bearings. In my eyes alot better than the 850 i torn down last year

Pistons

Piston


Con Rod Big End



Crank




Crank Tail


To be fair i've seen alot worse and these parts are pretty damn good and Ill refresh all the bolts in it aswell

Thanks

I would get that crank looked at, as a minimum the journals want a polish.

id recommend a crack test as there is no point building a motor with a bad crank and like said if its been thrashed on the grass it has had a hard life!

I will get it checked properly have it balanced. It is covered in gt85 atm too keep it for rusting also I have 2 998 cranks any ways.

I'll talk to fast Carl when its ready for that stage

Good NEWS!

It never made it into there Grass track car, it was the other engine he had for sale. this one came out a old metro.

Yo! :)
I don't think you actually need a turbo oil pump.
IIRC I read an 'ordinairy' oil pump is commonly used which would save you quite some cash.

Please have others confirm this as it is quite an important part of the engine!

Dazed and Confused....

For 20-30 quid id fit one anyday

Most people just keep a std oil pump. I personally bought the better one just because I would rather fit one.

Been thinking of dropping Boost from the build now..

been looking into 7 port heads.

Still wanting to do Injection aswell but really researching into it all at the moment nothing in concrete as of yet.

Got offered a MG metro short block today for £50 needs a rebuild worth doing over a tuned small bore?

worth keeping as stock if nothing else.

i already have 3 998's some bits of a 850, might aswell get it tbh at that price i props could sell the cam for that

Been a while since I have updated on here but I've started to weld the car now. But now I've hit a bit of an issue...




Do I weld door step in first or do the Floor and Inner sill first?

Id tack them all in at same time to get them all lined up where they should be

More cutting on its way then rear subframe mount at the same time too then?
