Well, it looks like I?m getting closer to starting this project.. A few questions for therock88.. I used your write-up for the front bumper removal ? worked like a champ! Thanks! - I posted a thread in the 997 forum with some pics. 1) My original thought was to use the factory plugs , but I see you used different ones. It looks like this was because of your tune.. I have a FVD tune and was wondering what plugs I should use or just stick with OEM? 2) Same Q?s on the coil packs ? why did you switch part #s? 3) I?m fairly certain that I will drop the engine to make it easier, since it looks like it?s just the 2 bolts ? I assume the hoses will stretch a little, and as long as you don?t drop it too far it should be okay? 4) Regarding the headers: Where did you get your replacements? I assume for performance reasons? Do you think you have to remove them completely (from the block & turbo) or could you just unbolt them from the flange of the turbo? And this is just so the turbo can wiggle a little bit for 2 of the plugs? Hi There....First I am no expert...just enjoy trying and learning, But I will try to answer your questions here and hope it helps: 1. I used the plugs recommended by the tuner. I would suggest you check with yours on what they suggest. Always use the best you can afford, and preferabley precious metals. A rule of thumb too is 1 heat range cooler for every 100 HP gain. Also the gap is important. For mine...factory is .048 and with tune recommended is .025. 2. The coild packs are the same as OEM. You will find a lot of that with Porsche....Bosch will sell them with one number, and Porsche will brand them with another. I was able to cross reference teh part numbers...they are the same, and I found these for a reasonable prce on the internet. 3.) Yes...Just put a jack or stand to support it and loosend the two Enging mount bolst and it drops down...I would say you have a good 3-4 inches before anything is at risk...Just do it slowly and only lower as much as you need too...it is too easy not to do it! :) 4.)Headers...Yes...got them for performance...from Vertex...these are Schnell brand. Regarding the movement...I would soak all the turbo side bolts with PB Blaster...and then you can just loosed them all....you do need to loosten the block side also as it really won't move with just the turbo side loosened it is pretty bound up. I do it so you can jiggle the turbo...otherwise more parts have to come off...and they are not easy to get too! Hope that helps...and good luck. Glad the front removal helped also...If any of you guys need anything I have published just let me know and I can likely emial it to you or link you to a quick web link I can make... DC
