Hey guys I joined the forum this morning. I've been plugging away at this project for a few years off and on.

I've been meaning to start documenting some of the build anyway so I figure this might make it feel like I'm making progress lol.

I'm curious, why the floor pan mod?

Most of what was removed in the first picture was a strange mixture of rust fiberglass and undercoating. In other words the stock floor and sides were rotted. When I rebuilt the floor I went straight inboard from the pinch weld to the trans tunnel.

 

I'm not sure if I'll ever do it at this point but the thought at the time was raising the floor would allow room for underbody aero and diffuser. This thought process also influenced the odd rather high placement of the fuel tank.

 

I don't have a good pic that shows it but everything (lines exhaust etc) is packaged in the tunnel above the frame rails and trans cross member. If I ever do want to go back and make aero parts I should have a good starting point.

Gonna be lazy and copy my FB post:

 

Today was awesome. Finally got the Datsun on the dyno and it did everything I hoped it would. Double D Tuning was super helpful and patient while we chased issues for the first half of the day. Ashley (Fiance) was a super star running around for parts and keeping me sane. I wouldn't want anyone else by my side.❤️❤️
I wanted to keep it conservative on pump so we stopped at 400. On E85 the goal was 500. It did it on the first clean pull after we had two people sitting in the back to prevent wheel spin, but fuel pressure was dropping. Luckily Adil (friend at the shop) had a drop in 525lph pump. We did one more pull again with two dudes in the back and it wheel spun to 527 with solid fuel pressure.
I'm on cloud 9. This is a long time coming for me and the car did exactly what I hoped it would 😎
Also...does anyone have a level so I can measure them torque curves?
