Air conditioning in a 240sx with an LS1 swap. The complete post.
The most frequent questions I get are about my air conditioning setup. I’ve had it working for almost a year and have finally put everything together in one big post. Most everything else about these swaps is now taken care of with swap kits. The air conditioning is a bit harder due to the fittings…Read More
LS1 Crank Pulley Installation Tool
I made a tool for installing the LS1 crank pulley. Lots of people use long bolts or all thread with a couple washers. I made a complete tool that includes a thrust bearing and full face washer to push the pulley on. It went on super easy. I have created a full print of the…Read More
Hooking up the power steering lines backwards. Don’t do it.
So the power steering lines on the back of the rack, don’t hook them up backwards. I was hooking these up with the car just barely jacked up and I apparently switched them.Read More

Turn One Power Steering Restrictor Fitting
I just installed a new Turn One power steering restrictor fitting in my stock LS1 pump. This fitting brings the LS1 pump back down to the pressure of the stock Nissan unit. I can’t say enough about how happy I am with this part. Best $35 I’ve spent on this car in a long time.…Read More
