Daniel,
Personally I like the Z18ET for its simplicity and ready availability of
parts at bargain basement prices. CA's are great as well but the parts
costs are murder by comparison to an Z engine!

Subject: Z-18et vs CA-18det conversion

List,
I have recently accumulated enough funds to get out of my gas guzzling twin
45mm hotted up L series (I'm going to miss that induction noise and exhaust
note!). Here's my deliema, do I go for a Z-18 or a CA-18?
My reasons for the Z-18. FAR LESS hassles fitting to the existing cross
member, no need for new sway bars etc and I reckon a little more suited to
the car as far as weight goes. Since the block is basically an L series, I
would have far less troubles rebuilding it since I have a bit of experience
with the internals of these engines. CHEAPER! Plus my gearboxes I already
have lying around would fit up to it.
Reasons for the CA-18. Newer, not an import engine, so parts would be
easier to get (I think, correct me if I'm wrong), more power from standard
and double overhead cam.
Whichever I get wont be going in the car for a while. I plan to tear it
down and rebuild it from the ground up. My plans are to get all the rods,
cranks and pistons balanced. Rods and crank toughened up ie crank polished
and nitrided. Either a set of forgies or high quality cast (that might
create some contreversy). Block fully prepped and probably O-ringed. Plan
to also get the flywheel lightened and balanced with a stonger clutch.
Don't want to do too much to the head except maybe a valve job with bigger
valves and a mild port job. A big cam would be nice since I love hearing
my engine scream at over 7400rpm so I would love to keep this in my new
engine, but what do people think? Also keeping the STANDARD compression
ratio.
Outside the engine I want to probably put some bigger injectors in and
build a custom exhaust system to the turbo and a 2.75 or 3 inch dump pipe
off the turbo. I will probably keep my current 2.25 inch system from the
extractors back as its the biggest that the guys at the shop could fit
through the rear crossmember. The turbo will stay standard at the moment
but will have a solenoid control bleed switch on it. The intercooler will
also be upgraded and front mounted but wont be huge, I want one that would
look pretty stock if the 1600's came out with a turbo intercooled engine.
Anyway really sorry about the length but just wanted to give you guys an
idea of what my plans are to do. Whichever engine I choose will be built
slowly and over a period of about 6-9 months as extra funds become
available before the actual transplant occurs.
Any feed back would be hugely appreciated.
