Tom, are you planning to use water injection on
your setup. I assume not because your engine is already injected so you
only need to intercool it. A few reputable people and a some really good
books that I have read have told me that water injection is just a bandaid
measure to cover up a really poor intercooling system.
Thoughts/suggestions?

The easiest would be a suck-thru L20b turbo, the turbo bits
would probably
cost probably $750-$1000 (custom exhaust manifold, turbo,
tubing from turbo
to stock intake manifold, carby to suck thru), then you'd
have to find a
good stock L20b. Remember that the L20b was never sold
with a turbo so it
may take the shop some fiddling to get it right.
The Z18 would be around
$1300 for the motor inc ECU etc. The Z18 uses
EFI, so you need to upgrade
your fuel system to suit (~$400). Both
are a pretty easy fit into a 1600,
you need your L16 sump for the L20b, and
your L16 sump with some mods for
the Z18. Most good shops will have
done plenty of L20b/Z18 swaps since
they're both very popular.
For
both swaps you need a good exhaust good brakes etc. For the Z18
you
will probably need an engineering certificate, maybe for the L20b
too
depending on how tough the authorities are in your area!
Check
out the file I attached which was compiled by Terry Rudd from this
list,
it's got a comprehensive run down of costs.
As to which one is faster,
assuming you chose a sensible size for the turbo,
the L20b will probably
have stronger torque than the stock Z18 down low in
the rev range due to
its longer stroke, but the Z18 will probably rev
better. I
doubt either would be much faster than the other, but the Z18
definately
has more potential since you can intercool it, wind the wick up
and use
aftermarket engine management. If you want to wind the boost up
on
the L20b you should probably rebuild the motor with lower
compression
(costly) and use water injection. That's the benefit you
get for the extra
cost of the Z18.
It all depends on just how fast
you want to go!
Which city are you in? Perhaps some listers can
recommend some good
workshops in your area

conversions
i own a datsun 1600 and i am looking to put either a
L20T or a Z18T. which
one would give me the best performance all round but
mainly from standing
start.Also does anyone know how much it would cost for
the whole conversion.
(none of the work done by myself).Any other
suggestions welcome. I have
about $4000 to $4500 to spend all up. some how
i dont think it is
enough.
