The V8 in action http://www.youtube.com/watch?v=vp5Eaf8xOgM
Well the engine hasn't lasted too long and the result is this..
July 28th the engine died.
Back onto jack stands...
once the head was lifted off this was the poor sight that was to be seen.
The block... the sleeve has been pulled down (through the seat and oil squirters and onto the crank
And the piston.....
so a new engine was purchased..
This time a M52b28
August 18th
A customer of the place im doing the work at was having a S50B30 conversion done and had not received a lot of the crucial parts one being the entire EWS set up.
His engine was also down on compression on cylinders 3 and 6. So after a couple of beers the decision was made to swap engines.
So on the 21st i removed the S50 out of the customers E30 and put it on a engine stand and bolted the supercharger up to it..
I then started pulling the S50 down and installed the M52b28 into the customers car
S50 pulled down
Found this damage to the bore on cylinder 3
the spacers that go in between the throttle bodies and the head
And now i also have the headers that Matt at the workshop modified for the customer. Im not 100% sure what i going to do with these yet.
Yesterday i took the block up to the machinist to check what size pistons to order. He will be bore the block, be checking the eccentricity of the crank mounting, shave the block mounting surface, finish the cranks conrod mounting surface's and the cranks mounting surfaces. The head is also going to be reconditioned.
I will be ordering the internal parts as soon as he lets me know what size pistons to order.

Did you get any dyno charts of your 2.5?
Yeah this one will be documented.
I have had the copy "RG" wheels for 4-5 years (just sold my genuine set last week)... best bet would be to buy a set of genuine alpinas from either Germany or the UK. A nice set of 16X7 and 16X8 make the car handle really well

Just a small update. been busy with work
got my engine back a fair while ago. cleaned it all up, sanded the outside and painted it.
installed the crank, pistons and rods..
mmmmm coated bearings for the rods and mains
block finished
Just waiting on 3 boxs with all brand new genuine parts to complete the base build of the engine. then i can assemble the rest of the engine over Christmas

So with all my boxs of parts it all down to building the rest of the damn thing.
Here is the new oil pump that has to be converted to 5 series pick up. (s50 is the longer arm)
new crank nose swapped over and all new timing chain and oil pump chain guides and the oil pump installed
Found out the old oil pressure relief valve was full of silicon so would have not worked.. so installed the new one
timing case goes on
pistons 1 & 6 are moved to top dead center ready for head install. I am using a VAC motorsport multi layered steel gasket

bit of a picture update
this is the o-ring kit you get... a pain to find the right o-ring as they all seem almost the same size..
putting the water pipes together
Picked up another exhaust cam sprocket from parramata prestige
got them machined with the hardening taken off and slotted holes put in.
trial install
exhaust cam put in so that the valve clearances can be checked which seem to be a fair way out. Then shims will need to be swapped or new ones bought
Does anyone know the specs for a S50B30 valve clearance?

Inlet and exhaust clearances are the same for the s50 b30 which are 0.28-0.33mm. ( cold ).
sooo ive started heading in a different direction again as the supercharger is going to be dificult to fit where i would like it to go. so i have choosen to go turbo. Meaning my supercharger will be up for sale.
i have orded my shims finally as this has been a great pain the the backside but i am still waiting for them to arrive. so in the meantime i have thrown the engine in to test fit it.
turbo purchased
I decided to mount it low as there seems to be more advantages than disadvantages for me.
going to have to make a new engine arm so the dump pipe can fit.
a picture of what it would look up top.

what the hell happened to the M50 to have that happen?!?!
love s50's, awesome project!
why not just stay N/A? the stock s50 isn't exactly slow

Bad tune by the person that tuned it.....
Because i bought a new m52 to bolt everything back up to but a customers car was missing all the ews for the S50 so he asked if i wanted to swap engines. I said yes and became the new owner of the S50. Then i was going to rebuild it and use the supercharger because i all ready had it and i was going to replicate what was used on the tauber built car but with twice the amount of boost.
Now i have decided that instead of running the supercharger down the bottom on the exhaust side i may as well just run a turbo.

Nice project mate, I remember reading it a while back but it's fair moving on now, good luck with the S50 turbo build, I hope you get this one tuned right so you don't have to do this all over again

So after spending some time away from the project i decided to go back to NA and had to rebuild the engine again with forged CP stock compression pistons. I have run out of time and motivation to turbo or supercharge this car. Plus we are running out of tracks to go on in this part of australia and the prices are only going up.
had to put in a locating dowel for the magnet to pick up the cam angle
underside of the plugs
there are also plugs for the rear cam sensor pick up holes
reinforcement bar for the front
ready to leave to go to the exhaust shop. first time its hit the ground in 2 years...
exhaust work
now back at home to finish off
