Hi . Im planning on building up slightly crazy NA package for my 1200 ute. anyone here built up thier CA to that spec?

What cams you gonna run?

Don't dick around Chris.
A mate of mine swapped out his wild A12 for a ca18de. He was bitterly disapointed with the result. With the extra weight, it was slower around Ruapuna than with the A series. He went to a CA18DET very shortly afterwards, with much better results. If you are are going to add that extra weight, why not go the Whole hog?

Yeah, If you're going CA..... You may as well go the DET.
If you're dead set on a N/A, why not go SR20?

The weight made that much difference?
A12 = 87kg, worked motor I guess 90hp
CA18DE = 113kg, stock 130hp

Maybe it wasn't weight, could it possibly have been that the front suspension needed some adjustment to account for this extra weight? It is about 25kg of extra weight roughly over the front wheels.

I think the extra weight would make a bigger differance to handlingrather than straight line performance.

Granted the extra weight would change the handling characteristics of the car, but could it alter the corner speed so greatly - this extra 25kg - to make it a tragedy to drive?

And couldn't this change in weight over the front wheels be accounted for with stiffer springs and matched shocks?

I would expect a quicker lap at Sandown with a CA18DE under the hood as compared with a hot A12.....

The CA18DE would at least represent a 40% increase in power. for 25kg more weight...

The DE is a torquey beast. I had a CA18DE in my 1200 Sedan for 3 years in the mid 90s. It used to rip seconds with 5 people in the car, felt very strong. A complete difference to the stock A14 that was in it beforehand.

I think lightening the flywheel would free up a lot of acceleration. The stock flywheel is designed for a car almost twice the weight.

The car I was refering to had 910 front struts, with avenger stationwagon rear coils. He had also built adjustable everything for it. It was a VERY smart handler around the corners, but the A12 gave away too much on the straight.

Er...there goes the suspension theory then.

The extra 25kg made that much difference?

I am considering a CA18DE installation (once I decide I'm rich enough and insane enough to try)

I thought the extra power for very little weight would make a much finer car.

Anyone else opted for non turbo CA18DE and found it to be a ball tearer?
