Hey what is the exact part # for the plugs I need to run NOS the idiots at all the stores here can't figure out the Colder plug issue! Also do you know where the fuel pressure safety / cutoff switch should go everyone just keeps saying on the fuel rail but where, I am installing a dry kit that uses the fuel injection pressure what should the NOS and fuel jets be set to? For a 150 shot. Thanx a million !

 

What brand plugs do you want?

NGK TR55's are good up to 100 RWHP relaibly
NGK TR6's are good up to 180 RWHP reliably

Autolite 105's are good up to 100 RWHP relaibly
Autolite 104's are good up to 180 RWHP reliably

The NGK's have better @ idle manners and are less likely to throw PO420 multiple misfire codes but Autolites are definately more abundant.

Which NOS dry kit are you using?

5176 bypassing dry
5177 MAF compensateing dry

In either case you are going to need the -4AN fml to 1/8NPT fml swivel adpator p/n 17982-snos (the 5177 kit includes this, the 5176 kit does not)

dependant of what RWHP results you want you will need to run between .061 to .067 jet and a .045 in the fuel "T" if this is a 5176 kit or some derivative of that. If you lower the bypass "t" jet from a .045 you will increase fuel pressure but remember that you may need to shim the nitrous regulator spring.
