Dude we can do this in my garage for free! I do mechanical work all the time. Now that I have the house I have the garage fully equiped to do small projects to full engine builds. I am always building Jet ski engines and wrenching on my own vehicles.
Just let me know when you wanna do it!..
Edit: I should have fixed the Nismo’s coolant leak before putting it away for winter storage. I hate paying other’s to do work on my own car. Everytime a shop does something, I usually end up redoing it myself. When I had my rear end & gears done I had them do my hose kit. Instead of taking the time and removing the bottom shield to access the hose they cut corners and tried to do it from the side and never got the clamp on straight. So now I have to get under my slammed Z to try and fix it myself! Arrr SHOPS no matter how good of a Rep they have, they will eventually just violate your trust.
