I have a brand-new set of Q-Logic speaker pods for your kick panels....never been used. I opened the box to look at them and stuff, but never installed them. Sold the car before I could put them in :( I paid $150....I'll sell for $100.

I want to increase the boost in my '87 GN, but it's mostly all stock except for some intake mods. I'd like to know what I would need and how much it would cost to get around 17 lbs of boost on 91 octane? My local import speed shop said they could install a boost controller for 200 bucks...

When I start my car up from it sitting for a couple hours, it idles alright, then after about 20 seconds it boggs down....almost dying, then revs back up....then it does the same thing about 5 or 6 times, then it idles fine. What could be the cause of it?:confused: Could it be the injectors? I...

When you install the 6x9" speakers with the adapters and everything, is the bass response any good? I'm thinking of purchasing a pair of Infinity Reference 6x9" speakers with a JBL amp to give 'em juice....think it would sound pretty good? I don't really want to put subwoofers in the car, so I'm...

I want to replace my injectors in my 87 GN, since it has about 54,000 miles and I heard that the injectors should be replaced after 50,000 miles. I want to get some nice ones, but want some stock-ish replacements. I just need some recommendations. Thanks!

I am looking for a chip for my car, but I don't have a lot of mods done to it....just an LT1 MAF w/ translator and a mandrel-bent tube w/ 9" K&N filter....maybe some exhaust. I came across the Thrasher chips and wanted to know if they will work for an almost-stock GN, or which chip WILL work for...

I want to remove my engine from my 87 GN to powdercoat some stuff....how big of a process is this and what are some tips I should have before doing so? OH....and how hot do you think the turbo/exhaust gets? I found some silver powdercoat that withstands up to 1000 degrees! So yeah....if anybody...

I am wondering some stuff about some parts I found in the Poston catalog I got. Duttweiler intercooler neck - What does it do? Kenne Bell cold-air kit - how much more hp can I expect from this than my aluminum intake tube with K&N? chips - Which one is best for my car? Red Line...

I own an '87 GN, but it's back home in Minnesota. I am currently in Laramie, Wyoming attending Wyotech. I saw a really ratty-looking '87 GN driving around, and got next to him at a stoplight with my 97 Grand Prix GT. He took off slowly, but immediately I heard the turbo spooling and it sounded...

Would it be cheaper to get the Hooker cat-back system or get a local exhaust shop bend me some 3" piping with a couple nice turbo mufflers?

I was looking through Poston Enterprises online catalog, and I have chosen some items to purchase and I am wondering what hp gain should I expect: 3" downpipe high-flow catalytic converter high-flow crossover pipe Hooker exhaust system I think that should bring me to a pretty good hp...

I was on www.turbocharged.com and they have compressor upgrades....what would that do? Would it spool faster and all that good stuff? And would it be expensive?

I have seen the ad for "Poston Enterprises" in numerous magazines for years and years, but now that I have a GN, I am wondering if they are worth buying from. I was going to call tomorrow and order a catalog from them, but I figured I'd go here and see if anybody has had any problems with them...

Hey, I am just wondering....how do I get my stock turbo on my 87 to "whine" louder? I love the sound of that turbo spooling, but I'd like it to be louder than stock. Oh, and how do I quiet my wastegate? I know it's louder because of my K&N, but I am really getting annoyed by it. I want MORE...

I was wondering how to get more low-end torque....I hate waiting for the turbo to spool up so I can spin the tires, and sometimes I can squawk the tires in 2nd gear, but sometimes it doesn't....I WANT IT TO ALL THE TIME! So yeah, if anyone can help, it would be greatly appreciated. Thanks a lot...

I am looking for some new parts to make my engine compartment stand out....like new polished intake tubing and all that good stuff....also, I am looking for a new hood insulation mat with the "turbo 6" logo on it, and I can't find anywhere on the internet that has this kind of stuff....any help...

I was wondering if you could put a Monte Carlo gauge cluster in a GN? I just hate those damn gauges in our GNs and want to get actual round and accurate gauges....not like the "slide-bar" tach and boost gauge. So yeah, if anyone has attempted it or has had this same idea....please let me know...

I have a set of GNX wheels on my 87 GN and I am wondering....is the "rim" of the wheel polished aluminum or is it chrome-plated? I haven't seen the car in a LONG time, therefore do not know what they look like. I am just wondering what I should use to clean them when I get home next week. Any...

Hey, I was just wondering where the hell is the wastegate at? LoL! Stupid question, huh?

I am looking to upgrade my exhaust....I am pretty sure it's all stock, but I want to get a cat-back system. So far I have found the Hooker system and Flowmaster system. Which system performs better out of the two and which one sounds better?
