I’m putting an engine back together and was setting the preload on the lifters. I have Harland sharp rockers and I found a couple of the adjusters difficult to turn, so I backed them out and found the adjusting screw has broken on a couple of the arms. I see on Harland sharp’s website that I can...

You can see most of my upgrades in my signature. Anyway, when I ordered the new intercooler from Jason, I let him know what mods I have done and even with all my upgrades, I am still running a stock intercooler with a duttweiller neck. Well Jason told me to expect an increase of 70-100 HP just...

I have a transmission built by art carr that I got from them 18 years ago. It has held up really well, still shifts great, have done fluid and filter changes more often than I need. Anyway, last year I put a powerlogger onto my ECM and started tuning, but noticed that the logger is showing 3rd...

Very nice setup. I have a quick question though. There are two longer wires coming off the TR6 harness. I know that the orange wire is for the two step trigger, but what is the longer black wire for? It does not say in the directions. I'm sure some others know. Thanks Matt

well, now I just had to change things. I just installed the GN1 4 inch mafless pipe because I really like how the air filter is out of the way of the AC lines. I also moved the LS1 maf to the up pipe. Where I had great BLM's before, I now have low BLM's (115) so now because the maf is...

I was thinking during the Woodward dream cruise week leading up to Saturday event. I know that we have a group that meets on Woodward across from the moose preserve. I was looking and saw that they need a minimum of 30 people to reserve a visit to the GM Heritage center and it's only 10 dollars...

i did not know I had a problem until I decided to go to the track for fun. Well, my gn smokes, but only on full throttle and held for three to four seconds, then it just smokes until I let off. Does not smoke at idle, or driving, it does not smoke under full boost if done for less than four...

Well, the list so far is pte 66 turbo, dutweiller neck on stock ic, built 200r4 with a 3200 stall, razors alky, 60 lb injectors, walbro fuel pump with Hotwire, ls1 maf with translator, extended chip, all necessary gauges and scanmaster. The bottom end is built with a stroker crank but the top...

My wife and I are pondering purchasing another Buick GN. We already own a 1986, but a good friend of ours is moving and wants to sell his 1986 GN. I've known this car for a lot of years, it is in beautiful shape and is completely stock. It has 27,000 miles on it. Nothing done except maintenance...

My wife and I have gone to Woodward Dream cruise for the last several years, but we were thinking of participating in Flints B2B. We don't care for the cut throat style of obtaining a spot for the day and don't care for paying a huge amount of money for a spot. How is Back to the Bricks? I'm...

I just put in the new engine. All new bottom end, stroker kit, bored .040, forged Pistons, etc. also have precision 6462 turbo, alky kit, ls1 maf with translated, extender chip, remote oil filter with line going to turbo, 3300 rpm stall converter with lockup, 200 r4 with good internals. I have...

I'm located in the Kalamazoo Michigan area. Thank you!

Well, I thought that maybe the stock bottom end would hold up until winter, but apparently not. Was driving and went to pass a vehicle and stood on it and poof, all the sudden a dead cylinder and lots of smoke. Smoke is being pushed out of the breather, so along with a dead miss, I assume a...

well, having a little trouble tuning. Pops at wot and sometimes part throttle. New plugs r42s, good wires, coil, etc. have used the translator to richen and lean fuel. Scan master recall shows around 780-820mv sometimes no kr, and sometimes it might show 45 degrees kr. No exhaust leaks. Just...

Hello, just got the GN out and running well, but I still have the stock DP and elbow on it. Small puck does not cover the ported wastegate hole very well. So just thought I would put this out and see if I get any hits. Would love to find one this weekend if possible. Thank you Matt McClung

Just upgraded turbo and the gn is running great. I now have more lag than I did before, which I expected. I have a duttweiller necked intercooler, and I mildly ported the heads and port matched the intake. I still have the stock downpipe and elbow, I was thinking of getting a three inch downpipe...

My center console has the lower black side plastic broken on the drivers side. Was wondering if anyone has one around. Thank you Matt

I was wondering if anyone has a duttweiller necked intercooler laying around that they would like to sell. Let me know. Thank you Matt

I currently have a worn and passing oil TA49 turbo and want to upgrade. My engine is pretty much stock but I do have mildly ported stock heads, I also have 42 lb injectors on it. Putting the duttweiller neck on and the rjc powerplate. Have a solidly built 2004r and stall converter ( I believe...

Just like the thread title says, looking for drivers seat cover And front bumper fillers for an 86 GN. Thank you Matt mcclung684@gmail.com
