Where to get BIG top-feed injectors?

[Norbie]

So I'm building an 18R-G to cop a large amount of boost, and to safely handle the power I want to extract from it I'll need some pretty big injectors, like around 800cc. The 18R-G uses the old style top-feed injectors though - does anyone even make them this big? I know there are plenty of big side-feed injectors available for engines like the 2JZ, but I don't know about top-feed.

I thought about OEM injectors but the biggest top-feeds I can think of are the old 12A turbo rotary injectors which are around 700cc from memory, and from what I understand these are very hard to find now.

So can anyone offer any useful advice? Methinks my current 210cc injectors won't let me run much boost!

GTR's are top feed, so there is bound to be something available for them.

Look around at the Bosch units, i know they make some pretty hefty ones.
Indeed, some quick searching turned up this:

Now i know you dont want it that big, but they do come smaller.

Indeed, I think its a set of big Sard's that Glen is using and his is top-feed. How much power are you chasing? 800cc sounds MASSIF.

Jeremy you are a tool.

Choice 1 - Sard 760cc/min
Choice 2 - Bosch ~770cc/min
Choice 3 - Denso/GT-R/etc etc large top feeds....

Choice NOT - Rochester/Delphi/V8 styles


I will be buying the Sards. Perhaps you should buy the 'Tards

I forgot to add - you will definitely want to be checking up on the spray pattern of the injector you're looking at....

.... there are two basic spray patterns... split and single - split is for multivalve engines where the one intake port goes to two valves (eg, 7MG, 4AG) and single is what you want - one port, one phatty valve

bloody ripe off! the title said big! hahahaha i can put you onto a place that does them, prob about the $180 mark each from from memory ! pm me if you want me to price them for you as i have to get a set this week of them anyway. Ill price them and then you can ring and sort it with them.

[SL666]

trying to remember if my indy blue's are top or side feed..

[JustCallMeOrlando]

The power of Google says top feed....but they're MASSIF MASSIF.

[The Witzl]

$180/ea is pretty high in my books.... quite high.

But then again I have some good contacts
