Daniel,
I hadn't planned on using water injection, my plan was to fit a chunky
intercooler maybe with one of those water sprays from Autospeed. In my
opinion, I prefer intercooling over water injection because I am forgetful
and hate to think what would happen to my motor if I depended on it to ward
detonation off, had forgotten to refill the water tank and nailed it to blow
a rex or V8 away
There's some good reading in '21st Century Performance' about boost pressure
and pumped systems.
>From what I can gather water injection is generally used over intercooling
only when it's impractical (ie too expensive, not enough space for i/c, suck
thru turbo)
Anyway thats just my observations, if anybody else has anything to add I'd
be glad to hear it :)
- Tom

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

Subject: 1600 engine 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.
