I would go for option #1. You can later change/tailor the values of the fuses for the alternator or starter circuit. I think your fuse for the alternator is a bit high. I would try a 200amp fuse. This style of fuse is fairly new and not readily available yet at some retail stores. I would...

I have no idea why the bottom bung on the surge tank would be a 10AN size. I could see a high horsepower build possibly requiring a 8AN bung.

HCF Autosports (a vendor on here) created an aftermarket paddle shift system for the graziano gear box. If I recall correctly it was around $12000. Thread 'HCF Graziano Sequential conversion kit' https://www.gt40s.com/threads/hcf-graziano-sequential-conversion-kit.53101/

It may be very difficult and expensive to acquire the manual conversion parts however. They are in high demand and the wrecking/salvage yards know this.

I think the Bosch pump is intended to be the high pressure pump and the Walbro as the low pressure pump. In the past there was a bit of controversy/discussion over the Walbro pump. It only needs to be a low pressure pump and RCR was shipping out high pressure pumps. There is no regulator control...

The low pressure fuel filters job is to protect the fuel pumps from contaminants in the tank. Therefore it should be located before the LP pump. Here is how I would run the fuel system……..

I’d be interested in 2 of the air cups if someone wanted to buy the setup with only 2 cups.

I made a set off driving lights/brackets and trim rings for a GT-R. The goal was to replicate the look of the original car. The nose on the car is lacking a bit of style so these help jazz it up a bit. The trim ring mounts from the front of the bucket and the bracket/light mounts to the rear. I...

For just a little bit more money you could find a low mileage take out LS9 engine. It uses titanium connecting rods and titanium intake valves. The piston oil squirters help with detonation. In stock trim it puts out 630hp at the crank and with a simple pulley change it jumps to 680hp. Only...

You can remove the anodizing with Easy Off oven cleaner. I would carefully mask off the other sections of the injector with aluminum tape first.

Be careful with the DOT approval. It’s a grey area. The only thing about it being DOT is the buckle system. If your State doesn’t allow a 4/5/6 point harness on the road then the fact that type of buckle is approved is pointless. If your state allows those types of seat belts then definitely...

Welcome Zachary. I’m a current owner of a SL-C that lives in Manitoba, Canada. Feel free to pm me with any questions.

In a standard production car the roof structure is designed to crush. A 3 point belt is better matched for this. A 5/6 point belt is really designed for a roll cage. In most parts of Canada a 4/5/6 point seat belt is illegal for a street registered vehicle. I’m sure in some of the strictest...

Are 2lb residual brake valves really needed with our cars even when the reservoirs are generally mounted slightly higher than the brake calipers? I know the general consensus is if the master cylinders are lower than the calipers then it becomes necessary but isn’t that assuming the master...

A small triangular shaped file may be enough to clean up the offending threads. Zooming in on the picture…….the lower fitting looks like it needs cleaned up slightly near the end (between the first & second thread).

Work continues on the LS9 engine/ Graziano transaxle test stand build. I’m almost finished the 4 gallon fuel tank that holds twin pumps from a CTS-V. The pumps are PWM controlled from a CTS-V fuel pump controller. Those same type of components will be installed in the future GT-R fuel tank if I...

Here are a few pictures from my build log that others may find useful. Bill Phillips was the first to come up with the locking external Miata door handle modification. Cam has a video of its operation on his build log. I used the same design on my build. The first picture shows my design. The...

Here is a disassembled view of the hinge. My pen is pointing to the plate that was tapped with 7/16“ threads. The nut is used to lock the bolt in place.

My design uses a polished stainless 7/16” ARP bolt for the hinge. It uses a replaceable pressed in bushing on the swivelling section. One bronze washer is located on either side of the swivelling section to control side loading.

I made my own set of front hood hinges based off pictures I saw of the other styles builders came up with. I had to make mine stronger due to the fact I’m required to have some kind of front crash bar to pass inspection in my Province. Mine will not have any holes cut in the main plates.Thsee...
