So we got onto the engine and a valve had gotten stuck and ground down a lobe on the cam shaft Found a new block with Pistons and cam shaft. What would I gain boring it out 30 over? Original was bored 30 over. Would the gains be worth the cost? What else should I consider? Don't want to break...

After reading your replies I am thinking it would be prudent to pick up the car and do some more research before opting for a rebuild. I believe a second opinion is a good idea. I have a line on a TB mechanic who also owns an 87 GN in the area. I believe that will be my next course of action.

I am in the Tulsa, Ok area. The fuel system replacement consisted of higher psi injectors and fuel pump because since it has 60mm Garrett turbo it was running very lean on the dyno. This has been an "issue" car since I bought it. Previous owners have done numerous "work arounds" instead of...

So my turbo mechanic went to put my GN on the dyno after changing out fuel system and found valve sticking so he recommends a motor rebuild since we will have the heads off anyway. I need tips on what to go back with. This will be for the street with an occasional run down the strip so I want...

when I purchased my 87 GN w/ T-Tops, it had rear air bags and air shocks. I have since had the front and rear coils replaced and new air shocks installed trying to clean up the ride. I have also had the back seat brace and GNX rear end brace installed as well as the front brace. I hope this...

This summer I noticed my 87 GN water temp would go up 20-30 degrees at a stop light with the AC on. Would continue to climb if allowed to. I haven't let it set long enough to see if it tops out. Once it hits 220-230 I make sure I get moving. Installed new single fan but still gets hot fast...

So I have been working on bringing my 87 GN back to life after years of being modded and maintained on a tight budget by previous owners. I have been working on the the interior and exterior and now getting to the drivetrain. I have had this car for a few years and don't know any of the mods...

My power master brakes had issues and I had zero brakes so after installing a new acumulator and still having issues I had vacuum brakes installed. That way at least if there are problems I will have something. I mean I had zero brakes when the powermaster went out. I would have had better luck...

Thanks for the advice, I am looking for other turbo owners in the Tulsa area as well as recommended restoration shops. I actually bought the rattle kit from you and had it installed but the window is still loose and I was told I needed the rails. Maybe I picked the wrong installer? If you look...

i need some advice on how to tighten up my door windows I have a lot of air leaks at the back top corner as well as where the door window meets the T-top corners I had all rubber replaced but the windows in the doors are so loose they just don't put enough pressure against the rubber. Does...

Im located in Tulsa, OK and would love to find someone in this area that could work on and educate me on this car but so far I have had no luck so any help would be appreciated.

All good comments As I have said in previous posts, I have no mechanical knowledge beyond basic vehicle maintenance. I have to rely on others to tell me what this car needs and up to this point I haven't had much luck. My current mechanic seems to know his stuff but his main forte is Japanese...

What is an Alky kit and what does it do? Sorry to sound so ignorant but I only have the love for the car, not the knowledge

Does anyone know where I can get replacement door trim? I bought the adhesive style but realized this rivets on which means mine doesn't work and I can't just take it off without leaving holes. I looked at what I thought was most of the sites but no luck.

Thx for the replies They did replace the bushings as well as instal the brace mentioned in the first comment as well as the back seat brace. I hope to find out next week how it rides. I also get to find out how many HP this thing will have too. First attempt was stopped due to lean condition...

I will tell the mechanic of your comments Thx to all for the input

I think it is to atmospherE

Here is another question for you. My newly acquired 87 GN has been in the shop for a month now getting much needed attention and one of the things the mechanic installed is a blow off valve. He indicated that this was really needed so I said go ahead. He mainly works on Japanese turbo's such as...

So, I have an 87 GN with T-tops and going down the road is like floating in rough seas. I am having the brace behind the seat installed but what else can I do? I read somewhere about a bolt on frame brace that runs from the front wheel well to the rear wheel well. Is this what is needed or will...

I am in the Tulsa area and looking for other TB owners. I have only seen one other GN in the wild except at car shows in this area and would really be interested in talking to other TB owners. I am not mechanically inclined but have always been in love with the GN since I was in highschool and...
