Looking for all the help I can get.

[G_MAC1313]

Hello All,
I just returned from a three year deployment in Japan. It's great to be home. While in Japan, I owned my first turbo car, a 1989 Nissan Skyline GT-R. It was a great car but it's not American. Now that I am home I like the power of the Turbo Cars. You guessed it. I bought an 86 GN with 60K on the clock. I pulled the motor out and had her rebuilt with a laundry list of goodies, complete with ported and polished heads and intake, 60lb injectors, whalbro buel pump, 70mm throttle body, Cam, studded block, Steel head gaskets, Fuel pressure regulator, race built 200-4R, 3600 stall, carbon fiber drive shaft(had I know the cost of that I may not have it right now), front mount intercoller, waste gate, GReddy electronic boost controller, test pipe, and a Turbonetics T-62 Turbo with 3" down pipe. I am probably leaving a few items off the list. I dropped the motor and tranny in and and now I am having a bit of trouble with a few components. I was hoping someone can help me out or poin tme in the right direction. I need the vacuum lines and a diagram of how they route, Turbo/radiator hoses(a noticed a couple of little S-shaped hoses?), the piece that plugs in the the front passenger side valve cover. and the cover for the speedo gear. Any help will be greatly appreciated. I am looking forward to getting her back on the road.

Thanks from Oceanside, CA

Put a post in the parts wanted section on these boards for the items you need. Someone on these boards ALWAYS has what you are looking for.

Im sure somebody else will chime in with a diagram for you.

Welcome aboard!

This is the vacuum diagram from GNTTYPE.org. That website is the bible for information for these cars.
They are 2 S-hoses on the GN. One goes from the front of the intake to the water pump. This is the tighter S hose. The other goes from the metal heater line, bolted on the passenger side of the intake, to the water pump. This one looks more like a straightened out S. Not sure what you need on turbo hoses. There are 3 of them and self explanatory. Turbo to intercooler, Intercooler to Up pipe and Up pipe to throttlebody. Hope that helps

I think he might be talking about the hose that goes from the front of the pass valve cover to the inlet of the turbo. Some of our vendors sell a rubber plug for the inlet and a small air filter for the valve cover to help stop oil vapors from getting into the turbo. check spring cleaning on turbo buick.org.

Lovin' this site.

This site is great! The responses are very helpful and super fast. Thanks to all for the help. I am off work for the rest of the year and I am going to try and get her onthe road before the first. Any useful input is appreciated.

My engine builder says that I should fire up the motor run it for 10-15 minutes @ only 1500 RPM then let her cool completely and repeat. After that he says she is ready to run all out. Any thoughts on that procedure? I always break the cam in with a 20 minute run at 2000-2500 RPM.

Was a roller cam installed?

 

[G_MAC1313]

Hello All,
If anyone has detailed pictures of their engine compartment, could you send me some close up shots. I can model my install after a known working one. The turbo/heater hoses and the vacuum lines would be great. I am determined to have her on the road before 1JAN08. I think I can do it with a bit of help.

Thanks in advance for any help I can get. A picture speaks a thousand words!

Yes it is a hydraulic roller cam

Welcome...
Wow its a small world. I also purchased my 87 GN when I came back from a 3 year tour in Japan and also had a Skyline (not the GTR) R32 GTS-t with a built motor and trans and all (JCI was always FUN).

Roller cams dont really have a break in like the flat tappet. Sounds like you were describing a flat tappet break in.

 

[87GNSteve]

Yes it is a hydraulic roller cam

OK then you dont need to do the 20 minute 2000 2500 RPM break in procedure thats only for flat tappet cams
Do it like your builder said.

Hope these help a little...

Thanks

Thanks for all the feedback. Those pictures helped a lot. She is on the road and running well. She is not the monster I expected but still faster than the average car on the street.

Thanks to all,

It may not be a monster now, but it can be. Save some dough and start buying some upgrades... you wont be dissappointed. In stock form they arent exactly tuned very well either.

Do what I did, invest in a MAFT PRO ($400)(or a FAST system ($1200 if you got the $$$)
and get a innovative LC1 Wideband O2 setup to go with it ($200). This way you can tune the heck out of it. Tuning is everything for performance and to make sure you dont blow a headgasket or worse!

Hope you have a scanmaster to at least monitor knock an O2millvolts. At least get that if you dont have the coin for a wideband yet.

I have never owned a turbo vehicle until I got to Japan. This is all new to me so I thank you for the suggestions. Just last week I was running her pretty hard and KILLED a spark plug! Now I am leary about running the damn thing all out at WOT. I guess the chip didn't help that much. I will look into the Fast module but the guy I was talking to, was trying to get me for 25 hundy. Do you have any suggestions on where to get this stuff?
Thanks again,

Yep, They get in used FAST system sometimes and they wont rip you off and give you junk either. $2500 is nuts.

Make sure for the time being you montor knock... do you have a scanmaster?
I wouldnt be without one, even if you are going to get a fast system, its just nice to have something basic with some data to read on the fly. Especially
O2 millvolts and knock!

Once you got her all tuned up, then get a Razors alky kit and turn up the boost. I havent found anyone who did that upgrade that was dissappointed with the results!

Did you blow the spark plug clean out? Happened to me not long ago. Spark plug wire was just dangling there with ceramic spark plug in it. The metal part of the plug was still threaded into the head. I replaced all of the plugs and found another one that was lose and ready to blow out. They were Autolight plugs. I wasn't even beating on it when it happened.

 

[SPOOLFOOL2]

What exactly happend to the spark plug? Your scaring me. Need more info. What's the car doing. Is it rich, lean, are you getting knock? Any codes? Does your dad own a brewery? Is the fuel psi going up one lbs for every lbs of boost? "ALL" these questions will help us to help you.:biggrin:

Hope to see ya at the pizza cruz.
