Fuel/Air/Spark Can I upgrade now or wait till FI.

[gray1622]

I am planning on buying a Saleen SC in the future. I plan on using 39 or 42 injectors with GT40 pump with the wiring upgrade from Lethal. Can I go ahead install now without any ill effects being an N/A bolt on car? Will I need tuning for either? I know that some people use gt500 fuel system without a tune. What do you guys think the max amount of hp this setup can handle?

As far as spark plugs go can I plan on running colder plugs. I read that they will foul easier and I should wait till the SC goes on. Is this true?

As for MAF I plan on upgrading to Lethal GT500 MAF or SCT BA-500 slot style Maf and running my JLT II with lower engine mounts.Is Lethal just a gt500 take off mass? Which be better choice? Can I run it while I am NA? Also I know it need to be tuned.

I plan on staying on stock bottom end for a long time.

Random question on my gt/cs the thing in front of the radiation that gets beat to hell by rocks is that a air conditioner condenser?

Thanks.

The Saleen kit comes with 39# injectors and new plugs.

No need to upgrade the stock fuel system before installing. I am running the Saleen SS SC with the supplied pulley and stock fuel system which gave me 419 rwhp.

Save your money for after the Saleen installation when you upgrade it with a smaller pulley.

Yes, that is the AC condenser.
