Nizpro Drilled Injectors

[Trough Lolly]

Nipro make one injector now its called a 100, They are big enough to support over 450 rwkw's, Very easy to tune with and are cheap, 600 exchange.

←

for 600 one may aswell buy the bosch 968's and then they still have the stock injectors to put back in when they sell the car down the track.

a $600 drill bit would want to be a beautiful thing....

I have a set of Nizpro 110s in my car and the injectors are well within capability at 440 rwkW. The 110s are the biggest Nizpro did it at the time.

In the earlier days, they used Nizpro 60s (I think) but they ran out of flow around 340-350 rwkW. To give you some idea the 110s are about 910 cc/min, the 968s are about 440 cc/min and won't be able to support over 350 rwkW and have sufficient headroom (aka safety).

Also wrt drilling the injector, it's not done by Nizpro themselves. A specialist modifies the injector using a precision drilling technique and then checks the injectors for flow match (across the set of 6) and the spray pattern. Sure atomisation will be effected, but when you after big numbers you can't expect not to sacrifice some economy and emissions.

what is the flow rate of these?

[Adam]

I'm pretty sure they're 750cc.

These were the injectors Nizpro used when they passed the emmission test with a 400 rwkw stage three cobra kit.

You can get very fine drill bits that go up in very small increments from most larger hobby stores. I reckon this is all they use to drill the injectors in some sort of jig. Cant see any other way its done. Probably quite easy to do also.

phildub when they did that emmisions test was, that wasnt to meet the tougher Euro3 standards which are now in place, but im sure simon would be on top of that in any case

Lads, Would like to open up this topic again, as Ive just read the atomic website where they dont suggest using drilled out injectors.

Whats your thoughts and who uses all Atomic gear they sell....ducks guts or what?

cheers
