FYI, some where north of 28psi on a 1.5, head studs pull out of the block.

i ran ~35 psi on stock head bolts, and a stock gasket.. 1.5D.. the trans end of the block finally failed, and cracked all to hell.
thats why he is going to put a 1.5 rotating assembly in a 1.6TD block.. (a 1.5TD with strong head bolts/studs)
Do not lower compression,trust me..
If i built some think like this,maybe i use 1.4 na or 1.3 na base engine.Both engine has several benefit against 1.6 or 1.9
You can run less compression without a problem, it will even start decent.
UnderPSI - as I was searching the forum on this topic, I saw your thread about the big valve heads, including a 1.9 head with very big valves. Your Samurai looks bad-to-the-bone. Extremely nice job on that truck. Have you ever run a 1.9 head on a 1.5 displacement engine?

I haven't, don't see the need.
Are you running the big valve 1.6 head in your Samurai?
Are you running the big valve 1.6 head in your Samurai?
what "BIG VALVE" 1.6 head are you talking about? ALL 1.6 heads have the same valves..

I haven't yet, was busy with other projects, ordered my head studs and a low pressure turbo today though.
wait for dyno sheet.. 
the dyno is prolly gonna make me s#!t a buick...
nothing surprises me with you tho, Aki..
Aki - that 1.3 Polo engine looks deadly. It is a shame that we don't have those engines in the USA. I have heard rumors of some people who have imported "Gray Market" VW diesel engines to the US from Europe, but there doesn't seem to be a good source for such services.
I would be happy to give that engine a good home, and send it back when I am done, if you are interested in having your engine compete for a Land Speed Record.
Steve.
