Order of Install ? - S1, BOV, Intake, Wires

[jramosGT]

Hi

Just received my S1 kit from Tommy along with the MOPAR BOV, and the Crane wires that Tommy was selling. I also just ordered Adam's intake system, but won't have that for about 3 weeks or so.

Since I have to get into it, any recommendations for order of install? Should I wait for the intake system, or do the other things now?

Thanks

Git that stuff on your car immediately! I think the law says that aftermarket parts have to be installed within 3 days of receipt or they will not funtion correctly. Well, maybe not a law, I think it is like, a statute or something. [8)]

You might consider installing the Stage 1 and the BOV at the same time and you'll save yourself having to disassemble stuff twice. Without the PCM in the car theres more room to work on the BOV as well. If it were me, I'd 1. remove stock pcm 2. Install BOV 3. Install stage 1 PCM, and reassemble (trans learn procedure if its an Auto Trans}. Wires are the easiest to do. While you're at it install a new set of copper spark plugs (gapped properly) and don't forget the anti sieze on the plug threads, and the dielectric grease on the wire boots. Next plug change you'll be happy you didn't skip this step. You might consider driving the cruiser a little before doing wires & plugs if you're interested in determining how much difference wires & plugs really make.

Thanks for the info/hints. I figured there had to be a regulation on this since I'm so nervous about getting it done sooner rather than later.

I have a set of platinum plugs to install. Why do you say the coppers?

Thanks.

Because platinum plugs aer not recommended for Turbocharged cars. Yes, you can find people using them with no problems (yet) and yes, lots of manufactureres sell them. The problem is they use a smaller, hotter element to promote self-cleaning and long life. This hotter element can cause preignition (knock) so it's best just to use coppers and chaneg them more frequently. It's easy to do on our cars, so why not?

Where is this written??

I've been using platinums on my twin-turbo RX-7 since day 1, 117K miles worth. They were OE installed on purchase. The Supra Turbo and the 300ZX Turbo were likewise outfitted, so it's not just a rotary-specific item.

The recommended change interval is 25K miles, but turbo owners, especially those who use the turbos, have found that 15K miles is max.

Unless you can show me where platinums should not be used on a turbo'd car, I'll be using them.

Use what you want. While you're at it, change your oil every 500 miles or so, because that's when it starts to turn black. Make sure you use synthetic oil, too, to get the maximum wallet cleaning.

Here are a few places I found talking about use of platinum plugs in turbo motors. Beyond these, MX-5, who is a pretty damn good authority on these turbo cars, doesn't recommend them. I'll trust the word of a good mechanic any day over the word of someone looking to make money by selling me ten dollar spark plugs.

Just do a search for "platinum" on these pages and you should find what you are looking for. Many mfrs use platinum plugs because they last longer for emissions testing purposes, not because they optimize performance.

Enjoy.

""specialty" plugs will produce a less powerful spark than a standard plug will at the same gap. This means that, as long as your ignition system can provide enough voltage to jump the gap on the spark plug all of the time, with these "specialty" plugs installed in your car your engine will produce less power than it will with standard spark plugs"

If you do decide to go with platinum plugs...."The only way you can regain the power lost with these "specialty" plugs is to open their gap out farther (a wider gap requires more voltage to jump the gap).

I've seen a number of cases where people have installed SplitFire, Torquemaster or platinum plugs in their car in the place of standard spark plugs and have complained of reduced power. In all of these cases the specialty plugs were installed using the plug gap specified for the car's original standard plugs (with the exception of the Torquemaster, whose gap is not adjustable). The reduced spark power due to the reduced voltage requirement of these plugs was the culprit."
