Anyone have a decent intake crossover tube they would be willing to let go of that they don't want an arm and two legs for or know of anybody making reproductions. I had a little incident with mine today and I am now in need of a replacement. Cracks on the ends are acceptable as long as the main...

Not mine and don't know if anyone is interested but: https://www.ebay.com/itm/115612583351

Just a FYI on Apple Airtags being used by criminals.

I was looking at the corner cladding on my Sy and something seems just a little off about mine. I know the Sy/Ty/ and SoGT all had different corners and I'm wondering if mine are correct for the Sy or if it may just be a "less than perfect" repair. How would you tell which corners are which? Our...

Hey everybody, Our GM Turbo Six (Buick and Sy/Ty) group is going to be displaying at the Charlotte Autofair this Saturday and Sunday (9th & 10th). We are going to be on pit road so if anyone here is attending, come on by and say hello.

Hagerty at it again. Some more good press for our little black trucks. :) Now granted, the Sy doesn't win and that Rivian is one fast truck but if you take the cost of an average Sy and put half of the difference between the cost of the Rivian into the Sy, I think the gap would be a...

Guys, I've got a problem with my speedometer reading being different from my Scanmaster G reading. The difference seems to increase proportional with speed ie: at 50-60 on the Scanmaster the speedometer reads + about 5 mph, at 65-70 it is + 7 mph or more and etc. The Scanmaster seems to be the...

Hey everybody, My shifter boot has finally started cracking in my Sy so, looking for a replacement. I know the C4 Corvette boots are supposed to be the same as ours, but the question is what year Corvette? Up until 89 shows one boot where 90 and up shows another? Search pulled up lots of...

Spotted a Sy today (Sat 1/8/22) being towed north on US 220 near Asheboro, NC. Belong to anyone here? I actually had mine out and about today, but I was riding with my brother at the time and heading in the opposite direction, so I didn't have long to check it out. It looked sharp from what I...

Pretty good video on the Sy/Tys, but mainly the Sy. ;)

First, what dang transmission is in a Sy? Some say a 700r4 while others say it is actually a 4l60. Which one is it? Second, I think my TCC is not unlocking properly. I suspect the tcc lock-up solenoid is sticking. It locks fine but acts up while slowing down. I have heard that you can just...

Hey guys, I know this has been did to death in here but looking for floor mats for my Sy. I have what most people call the "92" model mats that are cut just like this: These are made by ACC but they do not offer the Syclone logos only GMC and Sonoma. Below is what Lloyd's shows as the...

Hey guys, trying to do driver's side motor mount on my Sy. I need more room. I've read that you can drop the diff to get more room without taking it all the way out. In fact I read where someone referenced just 4 bolts. Seems too good to be true but like everything on these infernal creatures...

with these trucks. Not really engine tech but I was driving the other night and decided to play around a little on my way home. I stopped about a half mile from home and torqued it up against the brakes. When I launched, the truck (which has been running pretty good lately) started to buck and...

Hi guys, not really an engine question but it is under the hood and I figured I'd have more views here so here goes. I am having to put a radiator in my Sy. My fan shrouds are a little beat up so thinking about replacing them while I've got it torn down. Am I right in thinking the bottom...

Hey guys, my main odometer has stopped working. Any ideas, fixes for it or where can I find a replacement? Anyone know if any of the other GM vehicles use the same odometer? I know the Sunbird GT would surely be the same but I would have just about as much luck finding a Sy/Ty/GT one. Lol. Thanks

What's everybody's opinion/experience on the MSD 6A ignition box. I'm assuming it works on stock distributor ignitions. Anybody running them? Is it a good thing, bad thing, better performance, better plug life, worth it on a stock turbo truck, don't waste my money, and etc...

Hey guys, I have an issue I'm just trying to sort out. I posted this question two weeks ago on the TT forum hoping to get an answer there but no luck yet so moving the question here. Just wondering where our VelocSyty chips get the boost signal from for it's boost control function. I assume it...

Guys I know the stock dash gauge is notoriously inaccurate but I'm curious about a few things and hoping someone can answer. My truck has been down for a while ( I know, shocker, right?) and one of the things I've done during it's hiatus is rewire some of the dash. I managed to get the stock...

Okay guys, I know the original Sy grills had red GMC letters but wondering if they were chrome outlines or black-out outlines? It seems that in some of the grill pictures on-line of supposedly original trucks some are chrome and some seem black. Which is correct or are both of them correct...
