2-24-2012

just bought a new 12g295 head that is fully ported and polished, with unleaded valve seats so im going to use that instead of the head i got which needs loads of work,
then when thats done im reboring to 998 +40, putting the cam in and a x pin diff and centre oil pick up, then thats it until i can afford the manifold and MJ :)


3-1-2012

the head has come and was packed amazingly :L
http://www.theminiforum.co.uk/forums/topic/217370-how-a-parcel-should-be-packed/page__pid__2393709#entry2393709

the head its red but i will be painting it yellow to match the 998 engine and no one will be any the wiser :ph34r:


mmm ported and polished mmm :wub:


3-3-2012

right so the engine for now is going to be a
Fully strip down and rebuild so i know it will take the turbo and be running to the best of its ability, becuase nbow it is very rough and down on power :(


28/36 Weber Carb
RC40 1.75" Exhaust
LCB Manifold
Stage 3 12G295 Head
998+40 Making it a 1030cc
MG Metro Cam
X Pin Diff
Centre Oil Pickup

so hope fully that will give a nice 60 Bhp that will keep me happyfor know as i think the engine currently has like 34 or something low :L

so when i strip it down is there anything i should replace?
i will buy a full new gasket set
cam followers

not sure about the rest :/
new cam timing things, duplex?
any help would be amazing :)


3-10-2012

its my first time taking an engine out so im glad my mate knows what he is doing,

just 3 more things need doing before i have every thing together,

put new jets and things in the carb,
get the maifold welded,
buy air filter for the carb :D

the machine shop is gonna bore it and get the pistons, crank bearings and flywheel lightend, all i got to do is clean the engine down strip it, fit all the bits and then re fit :D


5-4-2012

Had an hour on it earlier before it got dark,
Got the bonnet and grill off,
All the radiator undone and the manifold bolts off,
Carb ready to come off,
Most of the water drained,
Got pics if you want them :)


5-6-2012

Cleaned all the engine off today, now it looks alot better, but it's still dirty I think I'll do the worse parts when it's stripped so I can move it around easily,
Also got the head off and had a good feel of the bores and they had some lovely lips on them :L

Forgot my camera so crappy quality phone pics will have to do,
I will upload them after :)


5-7-2012

i only knew that because i rang them up and asked if theve had a look at it yet, think they would of kept me waiting otherwise grrr


5-28-2012

im actually thinking someone hates me and doesnt want me to get this done,
i just had a call saying they recived the piston today only for it to be the wrong one :sneaky:
it was a standard 998 piston not +60
so he said he got in touch with the company and they are sending one out today and it should be there tomorrow :(

6-12-2012

did a bit on the car today,
i have an anoying knocking coming from the back end, think it was where the shocks go into the arches so i took them out and the rubbers look fine so i just tightned it as much as i could,
and i sorted out the shocks as the ride was very hard, the back shocks were set at 4 above softest and the front was like 2 from the hardest OPPS
so i set it to one click above soft on the back and 0 on the front :D
so it should be a bit softer :L


6-16-2012

ive got my second wind on turboing this again :L,
i got my passion for turbo back and i want it now!!
so the plan is getting the engine back in,
going to see my friend and talk about everything i need to do it,
get a megajolt,
get the rest of the bits i need and then do it!


6-19-2012

but it was making a loud rubbing noise from the the timing chain area,
i fitted a duplex timing chain but didnt know i had to modify the bloody cover,
so i had to drain all the new anti freeze i put in take the radiator out, lift the engine take all the pullys off, ruin a gasket just to do it :(

it started straight away after 2 weeks of standing, thought the battery would be dead.
back to driving it now :D


also i have annihilated my passenger side hub nut :L

ive always had trouble with my wheel bearings coming loose but today they properly went,
brake pedal went all the way to the floor :L
so i have to do that now and im changing the hub too because the bearings spin in side that


8-1-2012

the first choke is perfecr but when the second comes in it splutters and jolts so thats out, will just use the single choke for now and get him to change that when i go to the rr :)


9-12-2012

ive also ordered new front tires because i take roundabouts a bit to fast and have scrubed the sides off my tires well before they were due too,
after they have been fitted and ive had the rr i will get some camber set up on the wheels :)

8-4-2014

The turbo looks amazing!!!!!!

Looks brand new!


8-8-2014

Car is all done!!


Just needs an mot now


8-9-2014

just had my insurance quote for all the mods


anyone like to take a guys what the price was?


8-11-2014

had the turbo back and this happend when i offered it up to the manifold

 

 

 

but to be fair it was really easy to turn because it hadnt been through a heat cycle to it turned by hand with a bit of force.
also the centre needed turning but it was a case of just undo the bolts moving it and doing them back up

EASYYYY

 

 

spent all day working on it Friday got it all finsh and couldnt get an mot done over the weekend, NIGHTMARE

so my next day off is friday so that will be when its done

this is how it looks now

 

 

cant wait to get it out of the garage to get some decent pics and drive it of course!!

and the garage needs a proper good clean as its covered in rubbish haha


9-5-2014

The car is ready to be tried out again :L

Tried another oil drain design and hopefully it will be ok this time haha

Feels like I've been here a million times lol

Wish me luck guys:D


9-6-2014

Went up just now and got it running,

Doesn't seem to be any oil leaks,
Drove it down the drive and back up and it didn't leak, all the others have started leaking well before that so that's very good!!

I don't want to risk driving it about because it has no tax or mot,

But I'm gonna book it in for Monday and hopefully it passes!!

I'll upload the vid in a bit



9-8-2014

Booked the car in for the mot

Thought I'd get it all ready to go, got it up to temp extra,

No leaks

Drove it a bit further and sometimes it didn't want to rev,

Parked it up an let it idle and the oil started coming,
Put it up on some ramps and yep once again oil dripping from the turbo:(

Rang midland turbo and they are having another look at it, if it's fine I'm going to fit a scavenger pump and not have to worry about bad oil drain problems :)


9-11-2014

all back together and seams to be running well :)

 

oil pressure is a bit high i think, its at

 

60psi cold

40-45psi at hot

60psi when revved

 

no leaks yet



9-12-2014

OMG I DROVE IT


OH MY GODDDDD

SUCH BOOST

AND TURBO FLUTTER MMMMMMMMMMMMMMMMMMMM

 

MUCH TORQUE STEER


12-20-2014

im back from uni

went up the garage to try and find out what the oil problem is caused by

i got it running and at about 1500-2000rpm to check the blowby,
i didnt get it completly up to temp had it halfway up to temp and the oil pressure was 60 psi, i checked how much crank pressure there was by taking the rocker cap off and held my hand over it and it was like someone was blowing on my hand decently hard.

im guessing it shouldnt be like that?


12-29-2014

just done the compression test:(

DRY

1: 130

2: 140
3: 135
4: 130
