Sooooo, ive been drivin the GN
-
Managed to get the GN together far enough on Sunday night to go for a spin. At this point, its running, with lights, but no hood, and a huge hole in the firewall where the A/C was. This is good for watching for potential fires and such during intial driving. Also i have no charge pipe on the turbo at this time, just doing some N/A tuning for drivability and trans setup.
After checking over what i thought was everything, i went out of town a ways, about 25mph or so. Moral of the story, always double check your lug nuts kids. so as my drivers side rear tire cruises its way onto the drum, i hoped it wouldnt leave the wheelwell in a fireball of fury, while gripping onto my quarter panel in the process. It did not, I was grateful.
Result? 4 bent wheel studs and a chewed up inner wheel, not bad for a first time out.
Monday, get 5 new wheelstuds and open nuts. Order new front springs, cause i dont like driving the mullett wagon any longer. Install studs, drive to the rents house in the country. Enter old mans garage, notice small drops ofbrake fluid on the floor, discover that both the vacuum booster AND master cyl i scrounged form the junk yard for free, are bad. order new manual master cyl. Do some tuning out in the country for a bit, Jason shows up in the 300z. We line em up, he gets a length on me out of the hole, i gain steadily and put about 2 lengths on. a while later and about 4 fuel trim updates in the comuter, i put about 3 lengths on him, all while shifting at only 5400, N/A, this thing is gonna be fun.
Tuesday, get tach to read correctly, do some more little shit, adjusting hoses and whatnot, check everything over for safeties sake, figure out why trans is shfting irregularly and acting all in all, retarded. Switch VSS sensors around, cured. cruise some more. Go out to the Rents again, make a quick 1/4 mile blast. Scanner is showing about 105-110 trap speed, thats nice, car has about 1000rpm of top end that can be adjusted into the shifts. Oh, and that round spinny thing to hook up.
Wed, pick up new front springs and Master Cyl. Install front springs, rear sway bar, hook up front sway bar, and install shocks. Car once again kicks ass. Nice stance, and corners better than i could have dreamed. This thing would leave my GTO in the dust on a curvy road. Without the Drag Radials on the back of course.
Today, make aluminum plate for huge hole in firewall, install. Install hood. Car is much much quieter now, i like that. still plenty loud with just 1 4" race bullet on the downpipe. Cruise some more, starts to sprinkle, go back to shop. Clean, paint and install wipers and associated linkage. Rub all the overspray off the windows with laquer thinner, this helps in a big way. Go back out, about 12 midnight, adjust headlights to somewhat acceptible level. Almost take to the ditch after drifting an entire corner at 50mph on the way in. Gotta remember to get some normal tires on the back of this thing soon.
Friday, I hope to make a charge pipe for this thing today, get some acceptable tuning done this weekend on it, in prep for Test and Tune next weekend. That way it can look fast while it sits in the grass. Install master cyl and ditch that big ass vaccuum booster, i love properly set up manual brakes. Hope to have some vid up by sunday night, and some good pics. These cars never cease to amaze me with how sinister they look at dusk.BTW, i wieghed it, no hood but full tank of gas, 3380#, not bad

So there's no charge pipe on the turbo eh? But the turbo is on the car...Correct me If I'm wrong here, but wouldnt that cause your turbo to overboost and overall shit itself if you are getting on it...there's no pressure for it to build if it's just spinning in air freely...maybe I'm totally off on this?
anyway, nice to see its comin along!

NO...... a turbo is an input / output device
there is no way to overspin the turbo without the turbo feeding the engine
as i am doing the same thing now... till tommorrow

i assure you, its not affecting it in any way. that thing is very big, and without pumping air into itelf (being hooked up) it wont reach max impeller speed. Also, with a Thumper, very large frame turbo, that is of no concern for the most part, |this thing has like a 1\2" turbine shaft. (maybe not that big, but its freakin big.)

so when you gonna make a post bout your car?...and i beg you please tune it unlike last year! lol...10's? crosses fingers

So the turbo is not actually connected to the engine, ie: not having exhaust going through the turbine side?
Sounds like a exciting adventure and a lot of little bugs getting worked out. Should be interesting when it's ready and tuned.

I am thinking he is spinning the turbo, however he is not letting the boost go anywhere but to the atmosphere.
