D i still have not had the time to find out about the bore spacing.I did google ''bore spacing uno turbo' --some interesting bits on the Xweb forum and 2or 3 write ups under that.I was wondering where you got 1900cc from and then i read that build on Xweb.I see those pistons run from 80 - 87mm [never took note] I see they say the spacing is all standard [whatever that is]D if you read that xweb build you'll see its a mix of parts.In the UK they also had a 1800 or 2l with round lights at the back like a gtr.Will try and get the info.I've got lots on my mind now with my son in the UK and all the crap going on there. I told him to stay away from the public places if possible but no he takes his children to a play area.I tell him to buy jap cars and what does he do --- he buys VW jetta,audi quattro,and they all gave him crap --only good car was a honda.Oh yeah now he's got even bigger crap BMW.Damn where will it end. I'll still look for the spacing.

kids will be kids, while the oldies go for simple reliable datsuns :)

I was in New Zealand in 1985 when French agents bombed a Greenpeace boat
and pretended it was terrorists and fanatics as media termed back then
Was pretty scary as I and dad had just come back from being out at sea
and the incident occurred an hour later after cruising past the famous
ship called the Rainbow Warrior.

Now its top secret agents causing false flags everywhere to keep the public
in fear of an evil that is instigated by the same industry that thrives on
exponential weapons sales and government spending in the image of our safety.
watch Ripple Effect 2 for further interesting Government cover ups and the
unlawful imprisonment of the film maker for 150+ days on no legal grounds.
7/7 and 9/11 had the same training exercises setup where in 7/7 the bombers
are still alive and well yet people still believe BBC propaganda when the
evidence is right there in their faces. A compelling view

Either way its safer out in our datsuns or tinkering in our garages :)

will get the head spacing soon from someone who sells the heads new

L20b Z18et Z20 and NA20 = 95.2mm
SR20De = 97mm
unfortunately UNO head is 94mm
but SR20 block can be offset sleeved
go from 10mm to 14mm head studs as
the Uno is 12mm already very strong.


back to the Na20 roller rocker head for me
a shame as I love the UNO head, its so compact.
