I then managed to put the rods and pistons together.   and just using the old bearing I put the piston in and marked where and how much I need to clearance the piston skirts for the oil squirters...

once that was all done I put new rings and bearing in.... lubed her up and put them in for good ..as well as the squirters.

I then did some more measuring and just just using a 1mm (compressed) head gasket with 92mm bore (might be able to find something else). and working off what the internet says the head combustion chamber is(haven't actually measured mine yet)..

that put the compression ratio at 8.622-1 .. so will take what I need off the head to bump that up to 9-1 or 9.5-1.

 

cheers

also dug out some bits and mocked another motor up as my nephew asked me to have a play with a sc14 he bought .. (also something I've been die to play with for years now).

just slapped a alternator bracket on the intake side and put a bolt in to hold the SC .... all ways looks bigger on the motor..

I'm thinking .. mounted on the intake side , fixed vbelt pulley (not sure on size yet). side draft carburetor  and pipe into factory manifold..20220724_133351.jpg.fd8c6a33d54875c9e04b79b670d645b9.jpg

ive got a pretty nice party pulley that came on the crowns sc14 and made like 17psi. since the crown wasnt intercooled it just made heat and no power. 

could go good on this...

is it muilty ribbed (Pk I think) pulley?.

not sure if I'm going to put a fixed V belt pulley on yet..

just need to work out  a decent pulley size..

 

cheers

so some stuff I ordered for my motor has now been lost somewhere in the world ...so I'm a tad over it now..

 

so decided to play around with the supercharger (for my nephew)on a spare motor..
1st thing was to take the inlet side pipe and put it on the outlet side (just slotted some holes and removed a stud for that).
made some basic mounts and plates to be able to weld to.
sorted a location infront of the inlet manifold  and above the dizzy.(will need to go a little higher)..
now the outlet can just go to pipe straight onto the inlet manifold (where carb was). join them with a silicone joiner.
Going to run a side draft on the intake side of the sc14 (actually thinking SU carbs).
found a twin belt crank pulley  from a sierra (timing marks are the same ).
going to run a v belt so on the hunt for a late 80s early 90s sigma/magna aircon pulley..
and will make a tensioner.

as for my motor .. parts I ordered are now lost somewhere....so I'm a tad over it.

cheers

on the nephew's mk5..

I wanted to change the Sc14 pulley to v belt .. just for ease as the crank pulley is also V belt... and it looks more oldschool..I had a pulley the perfect size so I too the sc14 main pulley shaft and the v belt pulley over to a mate.

ha him lathe down the sc14 pulley to 46mm.

received_583162516798101.jpeg.361a11f2c01e696795795bc9ecf25b86.jpegand make the hole in the v belt 28mm.. so that the  v belt pulley can go on from the back and the 46mm on the sc14 would fit into the front of the v belt...... I know what I mean

made them super tight fit ... so had to press them together

still got to remove some of the IL magnet stuff of the sc14 ... but that should work...

and the crank pulley and SC pulley now should see the sc14 hit 10,000rpm when the motor hits 6200rpm.

so my mate mentioned to me this morning to see if I can clean up #3 and #4 chamber and get them I bit closer the #2.

that made me go and check them again and I found out that #2 was 44.3 and not 43.4 (yup I measured them,looked at them ,and wrote them down..... so yes I screwed myself up lol).

so I spent the morning measuring  and die grinding and measuring and grinding  whike trying to go go through anywhere.

but I did get them to
#1 44.2cc
#2 44.3cc
#3 44.1cc
#4 44.1cc

that's about as close as I'm willing to go... the last 2 took some work..

pics in order.
