A few questions I'd like some answers for.

[CThompson31]

Hey guys! Sorry I haven't been on for quite a long time. I've been busy with school. My graduation is coming up and I've been pretty much sent all over the place to get prepared for it. Haha.

So here are my questions...

Is it a bad idea to drop a Series 3 V6 into a 2001 Bonneville SLE, and turbocharge it?

Are those E3 Diamond Fire spark plugs are any good?

Have any of you heard of "pulse plugs"? If so, are they better or worse than spark plugs?

Where can I get a center tail light for cheap?

Have any of you had the upholstery on the ceiling/sunroof in the interior start sagging? If so, what did you do about it?

What are the best tires (brand and model) that can be used for both all-season and sport?

Is it easy to replace spark plugs in a 3800 Series II engine?

I'd like some answers for these questions. I've been thinking about doing some work on my car lately and these are a few questions I had in mind. I appreciate your help! Thank you!

I moved this to the proper section for you. That'll give you the visibility your topic needs.

One at a time:

1. No. Not if you have the budget for it and the budget to support it long-term (and you'll need money down the road after mods for sure)
2. Spark plugs do not 'create' power. And no spark plug can initiate ignition dramatically better than any other. The difference will vary by cylinder head and piston design, spark plug location, and injector location from engine to engine. Don't waste your money.
3. Yes, and they're not worth the money either. Spark plugs don't create power. You're better off with good copper plugs (NGK V-power TR55 for instance) and hotter Series 2 coils (97 and newer).
4. Ebay or Harofreak00 (see him for the coils too).
5. Replace or re-cover your headliner.
6. There is no 'best' tire. Start a new topic in General Chat or search. Everyone has their own preferences.
7. I think it is, some others think it's not. It's a little harder on the S2 than the S1, and the 2k and newer are a little harder yet on the rear bank. The trick is to know where they are, work by feel, and don't be afraid to throw a blanket over the motor and lay on it while you work the rear bank. Experience will help you, and it'll be a 30 minute job the second or third time you do it.

A lot of us have Goodyear Assurance Tripletreads and are very happy with them.

And when you do your spark plugs, buy something like this. It's very helpful.

I agree with Bill on those accounts, and in addition:

1. It's going to take more money than you think. It is entirely do-able, but you have to know the costs and the work involved going into it and be willing to commit to it, otherwise you're going to quit half-way through and scrap it. You'll also be without your DD for a while, so you'll either have to buy/borrow a car or find alternative means of transportation to work, etc (car-pool, bus, bike, etc).

6. There is no tire good in all those areas. Your best bet will be matched sets for summer/winter (depending on where you live, obviously) using either good All-Seasons or Snow tires on your winter set, then use some good UHP Summer only tires. That will maximize performance in all 4 seasons of driving.

EDIT: Joe, I was happy with them till they went to hell at 25,000 miles. I will never recommend Goodyear tires to anyone again.

7. Doing plugs on an 00+ isn't hard, just takes time the first time, especially if the boots are glued onto the plug (usually are the first time). Just dig in and do it, making sure to put di-electric grease in the boots and anti-seize on the threads.

Ed's advice on the dielectric grease will cut half the time out of your next plug change. Use a q-tip to slather the goop inside the boot and contact that snaps onto the head of the plug. A SMALL amount of evenly distributed anti-seize on the threads, and do the dielectric grease on the coil post and wire boots too.

They will come off very easy the next time you need to do it.
