defflepp1 Posted September 10, 2012 Report Share Posted September 10, 2012 So I recently bought a 1997 bonneville ssei with 140,000 miles. I know it's not a w body but it has the same engine and I like this forum better than the bonneville one. Anyway I just bought it and it runs great but I would still like to do a full tune up just so I know when everything was done. My plan as of right now is spark plugs-ngk tr55 copper plug wires-msd coils-msd oil-Mobil one full synthetic oil filter-Mobil one fuel filter trans fluid and filter O2 sensor supercharger oil thats all I can think of for right now, is this a good list? Is there stuff I'm missing? Where would be a good place to find the MSD parts? In the some what near future I plan on dropping to a 3.4 pulley, so if there are supporting mods for that I should do now? Any help at all would be greatly appreciated, thank you Quote Link to comment Share on other sites More sharing options...
White93z34 Posted September 10, 2012 Report Share Posted September 10, 2012 (edited) Sup Bonneville buddy First off don't waste your money on MSD parts. The stock coils are good enough for intense 10 second drag cars. Ignition is not really a weak point. I've always ran stock wires never had a problem... seems like more people have spark issues moving to 8mm + aftermarket wires then just using the stock replacement sets. I use Walmart synthetic oil.. or whatever synthetic is on sale with a good filter. You seem to have everything else bang on. Supporting mods for a 3.4 pulley. I know lots of guys run that on stock manifolds... most recommend headers or at minimum ported manifolds and a downpipe. I know autolite 104 spark plugs are usually favorite of 3.4 pullie'd L67s Speed daddy stainless headers for w bodys will work on a h body. You'll need a w body trans dipstick and tube as well as you'll need a flange welded in your cat back to meet the headers down pipe since h body exhaust is a bit different is different then w body Edited September 10, 2012 by White93z34 mobile post needed cleaned up Quote Link to comment Share on other sites More sharing options...
Andrew Posted September 11, 2012 Report Share Posted September 11, 2012 In addition to what Chris recommended, i would say to replace the LIMs with the good metal frame ones. Good time to replace those coolant elbows too. Quote Link to comment Share on other sites More sharing options...
defflepp1 Posted September 11, 2012 Author Report Share Posted September 11, 2012 Would you be so kind as to direct me to a walk through on how to do that on the supercharged 3.8? Quote Link to comment Share on other sites More sharing options...
