ok you see all my mods in sign. last ? on nos what size injectors should i buy svo 42 ,deil 36,38 stay stock fuel pump is a 255 just ready to get all this **** over i need to be able to beat a high 12 second z28 tired of the **** talking he fills like he can't be beat on the street.this guy has a 98 z28 with a 2800 stall 18" rims on back 17"s on front full bolt ons slp loud mouth and brags out the *** about low miles being on his car running like that like 54,000 its one of my home boys but its time to shut him down! so if u see something i need i'm missing please right me

 

You have an NX wet kit right? There is no need to upgrade injectors if this is the case. By the looks of things you already have a Walbro/Holley 255 pump? You should be good to go in the fuel department.

 

ok thankx for the info i just heard some stuff bout injectors working at 100 percent or 80 % and crapping out

 

if any one can answer what do i gap tr55 ngk plugs at? my boy putting them in his car tomorrow

 

You should be running TR6 not TR55s You should go colder for spray
TR55 are stock heat range. Tighten gap to 34-37 in m.02

I think he means that his friend is putting them in another car. For a bolt on N/A set up the TR55 usually like to be gapped between .050-.060, I think they come pregapped at .055 if I remember right. I run my TR6s at .034 with a 225 shot.

 

Just reread that!!!!!!!!!!
READ ,COMPREHEND, POST.
Well 2 out of 3

lol...

 

ok thankx about gapping thats a done deal. still trying to see about injectors and yes i will be running t6 plugs i seen a on a site that showed that changing injectors improve performance with a custom tunning power curve stays higher and dropes slower because injectors do not max out like stock injectors. it just could be a bunch of crap to sell a product but if its not i know someone has changed them in a simular set up.OK and before some one use search button did that so much **** come up i rather ask

 

It is mostly just marketing crap. If your injectors aren't maxxed (yours shouldn't be with that cam) then there is no reason to touch them. If you do need some down the road check out the Ford Motorsports 42lbs injectors (green tops), I've had great luck with them and you can get them new for $250 all day long on ebay. You will have to have the car retuned for the injectors.

 

ok thankx man

 

Exactly.
