[s-cars] 034 high output coils

[cody at 5000tq.com]

It's nice to hear that others had issues too. Javad made it out to me  
like I was doing something wrong and that he's never heard so much as  
a peep about the coils not fitting (likewise about the GT2071 turbo  
install issues I had).

When did you guys buy your coil kits? I installed them in December of  
this past year IIRC and it was then that Javad insured me that  
documention was going to be a major priority and supplied with furure  
kits ASAP.  I also suggested to him that if he revised the bracket  
just so it would shift forward about an inch it would solve  
everything. I guess he ignored that suggestion as well. We spent a few  
hours on the phone, after some heated e-mails, and I really thought  
some of these issues were to be fixed. I also had a ton of issues with  
the installation of thier GT2071 kit, so I became pretty displeased  
with thier product quality, and especially so with thier pricing. I  
can provide links to websites and piece together a GT2081 setup at  
full retail prices for $200 less then thier kit, and in many cases  
using higher quality products doing so. :-/


Phil you mentioned you had no signs of cross firing. You won't notice  
anything until one day your driving along and suddenly your crankshaft  
comes through the oil pan ;-). Seriously it's not pretty when the  
wrong spark finds the wrong hole, and it only takes one time to  
destroy your engine. It's very likely to not be something you can see  
hapening. As the boost pressure and likewise the peak cylinder  
pressure increases the air in the cylinder becomes more resistant to  
the arc, and the path of least resistance to ground can become a path  
through the wire insulation. You best chances of a cross fire event is  
at maximum boost and engine load, hardly likely that you'd be under  
the hood to see any arcing ;-). Just a warning, feel free to excersize  
you own opinion, I'm not trying to be rude or anyting ;-).


The plug wire tool I use is this one by MSD:

Super easy, and it provides a gauge for measuring the insulation cuts  
which is nice. You squeeze it in a vice to make the crimp.

More expensive, more professional, tool:

Then you'll just need some crimp ends. I re-used the boots that came  
on the wires to keep the clean look. On MSD's website they list boots  
and crimps together in packs of 100, which just may be more then  
you'll need ;-). I'm sure you can find them locally in smaller  
quanities.
