Opinions, lots of opinions.
I do like to build ZVH engines, my opinion is the oil system and the block on the Zetec blacktop is considerably better than the CVH and silvertop. The CVH head once you modify the rocker stud holes is totally reliable at 7500rpm, it also is mechanically strong internally. My findings are just the same as Karls and agree with pretty much everything he says (never met him or even spoke to him
.
Scotts engine is my old engine just freshened up and put on new management, my old box also. Its on standard valves and springs with solid Newman follower and a big cam to suite the GT30/82 turbo.
If Scott was to take the final drive from a Mini Copper S (same box) that would give him a higher top speed as it revs out at 155mph currently.
Also been thinking about Scotts build this winter and would like to take a bit further.
It was running 28psi and that was the traction limit on my old dyno with 4 people on the bonnet and ratchet stapped to the ground (205 40 17). My new single roller Dynojet should not have any issue in getting it wound up more. (fingers crossed)

Dont worry lads im not investing all this money into a car to polish it at shows. My aim is to make everyones car look slow, obviosly thats fighting talk as im sure people will contest that and also have faster cars. This year may be a push to have a competitive car but ill try my hardest. Ran out of cash for a few weeks but going to let the fresh paint have a week or two then get it built. Very few parts needed now. Be good to get them all out at pod

Im the same! keen to get to shows and can't wait to get to pod
will be a mission heading there for me though but worth it i hope! its the constantly never ending list of "little" jobs that slow me down in getting it finished!
something else i was wondering and theres a lot of knowledagable people on this thread so thought id ask,, is it possible for water to leak through the water cooling side of the turbo and down the downpipe? its not running as I'm re-doing some wiring etc but its loosing water and its coming down the exhaust?
cheers
