Finally upgrading the setup in my hatch at present I am running a 355 harrop stroker with 10.2 to 1 comp injected banana manifold blue top injectors roller rockers pacemaker extractors approx 280 rwhp

I have just bought a harrop single plane highrise manifold complete with efi hardware 1000 cfm throttle body and 38 lb white top injectors ?

This setup was on a 450 HP engine I was told.
The setup has not run for a while so servicing of the white tops would be needed imo

I don't know which injectors to use as my blue tops are not needing any maintenance I can't recall seeing to many 308 s with white top injectors?

While I am asking anyone know a good person in wa to take it to for tuning

Injectors are easy to change later man, i'd just run the blue tops you have now and if you end up with to much duty cycle go to the bigger ones :D

Cheers.

Hey Hayden I know your setup works after a bit of googling in between crises today I am going to ring Alan Gibbs tomorrow as it would seem he is one of the best .
I am running a standard delco ecm with a performance chip at the moment
I am considering getting a hpc or similar coating just wondering how thick coating. Is will it affect thread size or machine size for injectors ?
Keen to get new setup on and running but once on that will be it so want to get it right

All Gibbs is out of action atm he has just got out of hospital. He tunes on bye dyno and Justin operates and also tunes.
What are you coating the intake manifold? Shouldn't be an issue, the coating is paper thin

Not sure of there size but I always thought on the golden v8 s. That grey was standard blue first size up then green ?

I have rung cic in Perth and have decided to get manifold jet hot coated which will give me time to get these cream/white injectors serviced I figure if they were running on a450hp stroker then I should probably use them

Have not rung bye performance yet as too busy at work today home for a week tomoz so will ring them this week

Not too sure mate. I always refer to them in lb or cc and by brand. I'd say if they are white 36lb they will be the Bosch factory l67 v6 injectors.

060 by the electrical connector
6'67 on one side
D on the other side


next to the 060 is there a 10digit number such as this example 0 280 155 868 is for the S/C V6.
