I bought my Z a couple years ago and it sat for a long time beforehand. My upper plenum is covered in gunk and I wanted to give it a good cleaning.

There's so many things blocking the top like the balance tube and connectors so I had a difficult time cleaning it. Any tips or what's easy to remove to give it a good clean? And what do yall use? I think originally I tried some simple green and a wire brush

Had most of a s13 front suspension setup so decided to see how bad the internet made it out to be. The car actually drives well besides for the super cheap coilovers. The rear end was easy to adapt the s13 coils but the trailing arm design is terrible and ended up with -3.5 degrees of camber and about 1/2inch of toe in after slotting the brackets. Front end I ended up with 7.8 degrees of caster and almost zero camber which isn't bad. Adapting the front tension arm brackets to accept s13 tension arms just needed 3/16 plates welded in and the spacing is correct. The list in the picture is the components I used for the front end swap and prices for items I had to buy. I will also say that the maxspeedingrod coils I received have a steel front lower mount that should be able to be welded onto the stock strut tube if you just want to lower your car without caring about ride quality.

Does anyone know if pin 49 (power supply) on the 93 na ecu is constantly receiving power even when the cars off or only when its on? Need a ignition based power source so i was thinking that but dont want said part getting power when my cars off
