I have an 87 GN motor I transplanted into my 91 Firebird. I pulled it out of storage about a month ago. It has been in storage for over a year now. Initially, the car ran fine at idle and on the road. It was only recently when I took it out that I noticed the idle was rougher sounding than...

Where does everyone go for a dyno tune on their GN? Need to get a dyno tune done on mine. Thanks.

I'm trying to track down an issue with my alternator. I checked the voltage on the alternator while it's running and it's 11.88 volts roughly. So something is obviously not running right. When I check the exciter wire on the alternator while it's running, I am only seeing around 2 volts...

Part store owners or auto part extraordinaire. Looking to see if this part is ever sold separate on an alternator. It's basically the bracket that bolts the alternator to the accessories bracket. I'm guessing the motor twisting from over time cracked it. Do I have to buy a whole...

Have a choice of swapping transmissions. Wondering what the pros and cons of each of these would be for a low 11 high 10 second GN would be. The rear is a Dana 60 w/ 3:55 gears.

Who are some of the best out there? Nothing extreme. I have a 500rwhp car that I'm considering switch from my 700r4 to a 200r4 and looking for a good builder. Opinions / personal experience appreciated. Thanks.

Thinking about swapping transmissions and going with a 200r4 instead. My question is the size. Are they a lot smaller then the 700r4? If so, I imagine I'm going to have to change my torque arm and recut my driveshaft. Any recommendations for torque arms? I have a spohn in there right now...

Is it common (if the downpipe is semi close to this area) for these to warp and cause oil leaks? Because mine runs down from the front of my motor (pass side under the A-arm) and we replaced the gasket and it's still leaking. Should I just replace the whole thing? It might be warped enough...

Some videos from the other night. Good races. Thanks to the camera man for video taping / racing and the drivers for coming out. :) YouTube - ams tuned evo vs turbo firebird YouTube - rx7 vs turbo bird 2nd race with the RX7, he wanted the hit. The bird raced this 415hp civic also but he...

I use the smaller overflow unit from alkycontrol. Recently I've noticed that the more back to back runs I make, the more the little reservoir fills up. Even popped its top once. It's never done this before. Any ideas on what would cause this? Temps when driving around are 178-182...

Just got back from racing this Audi S4 with Twin RS6's an some other work done to it. Sucker pulls hard up top! I was impressed! I let out about 18 seconds in after he started passing on me. The road we were on was not the greatest with a hill right that came up. Great race and an...

I had gotten some blacktop tar stuck to my rear tires last night. Couldn't get it off with a towel and water. So we headed out to a concrete road with 2Liter Mt. Dew bottles filled with water to try and burn them off. Only good video we got. We recorded more but I keep getting a "bad file"...
