Default Supercharger parts question

Ok so ima try the $1500 supercharger build and i have a few questions...
first ima get NGK TR6 plugs and was wondering do i need the iridiums or the v-powers and are they pre gapped?
second does any vehicle come with 42# injectors stock that i can just pull off and use?
third does the walbro 255lph GSS342 fit directly into the stock fuel tank with out modifications?
fourth i have a egr delete and a pcv bypass will this interfer with the supercharger install at all?
fifth and final question what is a safe psi to run a vortech v1 non intercooled? i was thinking 8 psi at first but what about 10 psi?

I would keep it at 8 psi on stock internals and if going to 10 PSI definitely should be with an intercooler. Your GT comes with 19lb injectors and would need to be changed as well.

No those are a 7 heat range and you can not use them. They are what I use except I use the race version. If you try running those in your stock motor with small boost(8-10) they will not self clean and foul out. You need the TR6's.

I'm not sure about the focus pump cause I would never use it but the GT40 pump has to have minor modifaction done to it.


You can find 42# injectors for cheap on ebay.

Yes your egr delete and pcv will be fine.

Hey:

I went with the Focus fuel pump. I got mine from my local Autozone. It was like $50, it was made by Airtech? It was plug and play. My tuner said it was flowing well when it was tuned.

On a side note, if you are going for huge HP levels, you are going to max out that Focus pump. Save yourself from doing the project twice and just go with the GT40 pump with modifications. My pump maxes out at 5200 rpm, so I have no room for upgrades.

I have 8 psi of boost, it does the job pretty well.

Yes that is the gt40 pump. Only minor modifications are needed to install it.

Go to your local advanced auto parts for the tr6's http://shop.advanceautoparts.com/web...NEAMS__4177___
