I purchased my half cut 18 months ago through a WA company called Kinetic Revolution in O'Connor. $2000
I went this way as I was able to see and hear the motor running before I took it away.
They had a CA18-DE in stock also, as well as other half cuts. Im not sure what they have in stock at the moment, when I was looking this was the only CA18DET halfcut I could obtain. The example I purchased had 86000 on the clock and was complete with the exception of the struts.
I would recomend using spring clamps on the stanza springs before undoing the top nut on the strut. Or it flies appart as the stanza springs have alot of compression.
The 1200 springs I was able to compress by hand and got a mate to fit the strut top and nut,
I payed $2000 for a complete half cut here in WA and have done 90% of the install in the back shed.
My advice is what ever figure you come up with times it by 3. Every car I have built has gone over budget. My coupe was suposed to be a $7000 project. Its 80% complete and thus far is a $21 000 car.
I'm not sure where - I have tried here in WA to purchase new chrome trim for the gutters and with no sucess. Original trim is hard to source - post your findings. I would like to find someone who can supply new gutter mouldings. Not the stick on plastic type.
I can't see how the intercooler is an issue. With all the engineering I have gone through on my 1974 1200 coupe, the only issue with the intercooler fitment was that it was "pedestrian friendly"
I feel the standard Nissan cooler is a waste of time. So I had a custom one fabricated, which goes under the front bumper. (600 x 120 x 80)It aint huge but it's more efficient than the standard nissan item. The engineers I spoke to all advised against cutting up the radiator support in any major way.
