I will warn you first, they take no prisoners on this site, I've been flamed so many times I'm on Burger King's menu

right here's some pic's and the story so far

I bought the bottom end off a guy on vvoc, he had replaced the head gasket and fitted a brand new timing chain, but the very next day realised the head was cracked, so he decided to go z20let

The timing chain cover has the oil pump built in, I've already stripped and inspected the oil pump, no damage, a few small marks but that's to be expected (any gouges means replacement), so that was reassembled

then the brand new timing chain was removed, this will get re-used

next the water pump/ balancer shaft chain was removed, this was the original chain.

next the bolts were removed from the chain cogs

then the cogs and balancer shafts were removed

here's the 2kg each balancer shafts

Vocky have you seen this site they list racing balancer shafts in us though.

a good site, I will be using this cheaper method, unless I opt for an electric water pump

I cut the ends off the balancer shafts to create idle wheels for the water pump timing chain

I will get the ends of the new idle shafts cleaned up on a lathe

the rear bearing of the balancer shaft needs the oil feed blanking off, this is done by fitting collets - thus blocking off the flow

I have removed the thermostat housing, water pipe and water pump

these are quite heavy and could be replaced with a Davies Craig '110' electric pump

Ure a bad influence on me vocky...think i'll have to go find myself an engine now...

 

[vocky]

the old balancer shaft ends have been cleaned up on a lathe and now become the idler gear shafts

 

[vocky]

this is what the new idlers look like assembled

 

[vocky]

took the sump off next

then removed the pistons

the pistons

finished stripping the block tonight, the crank weighs more than the block

Was that matt bankiers engine.....if it is i got the TB and inlet mani off him...

yes it was

 

[vocky]

here's the block, cradle and crank

 

[Daz]

Well we can safly say its stripped down now...

 

[vocky]

next step is to spend money

eagle rods, lightened flywheel and lightened crank pulley

then get the crank balanced with the flywheel and crank pulley attached

then I need to decide whether it's going to be a turbo, sc or na bottom end what..

every last nut and bolt rofl..

you done any more with this Neil or is your new project taking up all your time?

it's on the back burner

my vx was a split second decision to buy and I wasn't expecting to get one till next year, so this thread will be a bit quiet

but I will be finishing it off next year

 

[Andy]

yeah thats what i thought
