we all started out the same

no idea on the ute weight sorry.

haha.. well now i look like a dick..

well i cant remember 100% wat it was i got to work it out again. anyways wats the weight of the 1200 utes?

thanks again for all the replys ppl

CR = compression ratio.

lol cr?
i have been talking bout the
Z18 with sr20 pistons. and standed rods.

i was just going to mention george fury's bluebird...!

as for the CR with the L16 bottom end and SR pistons, i think it would be WAY more than 8.5:1 because the rod is 3.0mm longer meaning the pistons would need flycutting just to bring them back to neutral deck.

if you want to use SR pistons, stick with the original Z bottom end. otherwise you'll need custom pistons - i wasn't sure of your budget when i suggested it.

polish the rods and crank (and nitride them for a bit of strength) and it'll hold just fine.

Just on the weight thing, I think my old CA18DET ute weighed in around 800kg with a bigger diff, brakes etc.

The engineered FJ may have been before they changed the power to weight rules (about 2 years ago?). I had problems getting an FJ20ET Gemini Coupe registered for the same reason but started the project before the rules were changed (and had proof).

The CA is a great engine, easy to work on and makes plenty of power. The biggest advantage of a CA over Z18 is that the number of S13s out there makes parts easy to find and fairly cheap (may actually be cheaper than the Z if you look around).

That said I remember Nizpro making ridiculous amounts of hp from a Z years ago. George Furys bluey cant be forgotten either.

BTW - posted a response up regarding whats involved in the SR20DET conversion on vb.

it will be a drag/street car, i would love a sr but these laws say i cant. even a fj would be nuts.
but anwyays.
i just dont like the ca coz of twin cams and so on. more parts to upgrade.

im not trying to be a tight ass. just i can get parts cheaper. and do work myself so its good. but i dont want no nice seats and so on. its all about all go no show with me

It all depends on what you want to achive with your ute is it just going to be a driver with a bit off power or an all out drag car.If I was on a budget id go a z cause ive had experience with them before and know what there capable off. But in the end if you chasing big power you cant go past a ca or sr.Also I know off a 1200 ute with a fj20 turbo in it in melb engineered so it must be possible

yer i got a z now. and love it. and can get another 3 or 4 of them if i need.

what would u go for z or ca
and why?
i want to keep costs low and repairs down to a less time frame.
e.g head gasket work, and so on

I was going to put a z in mine at the start but had trouble actually finding one that still had the inlet manifold as there popular for transplants onto L series engines.But if you can get one I say go for it even though ive got a ca in mine at least a z not to common
