as above, whats the differance between a small turbo & large turbo bottom end??

thanks in advance

 

Heard the small t blocks are better,not sure why.




Dave.

 

Small turbo have 4 oil spray jets under pistons

 

thought big turbo,4x4's have spray jets too.



Dave.

 

You can see 1 of them in this pic taken from <Nutter>'s post

 

Not 100% sure now.......lol... thought they have a spray bar like the early 1's (been a while since having 1 apart)

Dave go have a look at yours if its still in bits

 

our 3 door (200 blocked) has spray bars, but they look as advanced as Nutters ones.
the reason for asking is that i'll probably start a rebuild the escos soon, & i was thinking rather than bore the old block, it may be worth starting with a new one as new 200 blocks seem to be going at a good price these days, & i'll then have 11 years less rust & heat problems to worry about.

 

I know that Robs old EEC Escort have 4 bolt in spray jets instead of the normal bar

 

Steve@SCC,



Come on Steve, i'm on track next week.

Been built up nopw for a week and getting run in slightly.


All the engines have spray bars,not like nutters though.

they look like they have been machined in as an extra mod.



Dave.

 

Combe???

I'm on track there as well


It was about 4 years ago that I last looked at an EEC block so the memory isn't quite as good as it was.....lol

 

Getting old Steve.


See you on track.



Dave.

 

 

I run the EEC 4 block....the best there is!!!..Oil jets situated under the pistons for cooling.It doesnt run a spray bar like the other blocks.

 

Ah haaaaaa I was right....the memory isn't gone then...lol
