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...

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...

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...

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.

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 have an 87 GN and have dumped quite a bit into it just bringing it up to decent looking shape but now I need some mechanical and electrical work done that my normal mechanic doesn't have the abilities to perform. I could also use some help with the body such as wind noise from T-tops and...
