Yes, I know I already have a build/project thread… But it has now taken a new direction.
JVG and I were talking yesterday about our Nissans, and plans with what to do with them. He mentioned competing in Redline’s Time Attack series. At first I was thinking “yea, right… I suck at driving…”
Then I thought positive. Why couldn’t I compete in one of the classes?
So I went to Redline’s website (www.redlinetimeattack.com I believe) and read the rules for the street class. To me, it sounded pretty lenient. Fully built motor and head: OK. Upgraded turbo: OK. Suspension mods galore. The only real limit I saw was the maximum tire width for an AWD car: 255. The car currently has 275mm wide steamrollers on all four corners, so I will be sacrificing some grip, all while putting down more power. I don’t need a roll cage (it is a street car, after all) but I will be using a harness bar w/ Schroth harnesses w/ their anti-submarine 4-points. I will also have a fire extinguisher inside the cabin as well.
As for the motor, there’s still a ton of plans. I just purchased a brand new Full Race turbo manifold w/ a top-mount twin-scroll T4 flange on it, and it’s already coated. The turbo decision is still up in the air.
For fueling, I have a couple of options. The street class limits cars to unleaded fuel only, but I can use methanol injection. Ethanol fueled vehicles are also legal in all classes. Since E85, or E98 offer an overall higher octane rating than the 93 + meth, I may go that route, but I will not have the cooling properties of the meth. So that option is still in the air. Upon inspection of the car, there were many faults with it. First off, the clutch was different from what the previous owner stated. Instead of a Cusco twin plate, it was an Exedy triple. Instead of GReddy 264/272 cams, they’re actually Grex (same as GReddy) 256 cams, which explains the insignificant power gains. So here’s the new planned mod list:
Engine:
Tomei rods
CP pistons, with coated skirts and domes
Ported head
1mm oversize valves possibly
Tomei 270* intake and exhaust Procams
Tomei cam pulleys
Full-Race T4 Manifold (Purchased)
Turbo, undecided
TiAL 44mm wastegates x2
Custom FMIC
Custom intake manifold
1000cc injectors if using E85 or E98
Other miscellaneous things
Drivetrain:
Nismo twin plate coppermix clutch (Purchased)
Nismo slave cylinder (Purchased)
Nismo clutch line (Purchased)
Cryo-treated input shaft (Purchased)
Suspension:
GReddy Type-S coilovers, but may sell and go with a more track oriented setup
Sway bars
Top Secret front strut bar (Purchased)
Some other miscellaneous bars/bits
Wheels, Tires, and Brakes:
Totally unsure so far. Updates will come soon.
I plan on updated this post every week or so over winter, and a few times before then once the car is back complete and driving.
Thanks for looking
