TD42 Injectors

Has anyone replaced their injectors with aftermarket ones for improved performance in their GQ TD42? Not looking for standard replacement injectors.....but ones that can handle increased fuel delivery.
We have broken the injector spring on two injectors within a few months now, and were wondering if anyone else has experienced the same problem. Fuel pump is modified to flow significantly more fuel than standard, so it seems reasonable that the standard injectors aren't quite up to the job.
Any help would be appreciated.
Cheers
Mitch

I have a set in my own vehicle that now dont break springs as I had the same troubles. They are not nissan, so I dont know how long term durability on the engine will be. But I have no more spring breakages.

Andy,
If ya take Mitchs post date. Theres a god chance he has fixed his shit by now. But different injectors sound interesting. How do they compare price wise to the std TD42 ones setup for bigger pumps. I want be going all out. But if I have to replace/rebuild them. I think its worth me thinking about.

Never even looked at the post date. Probably looking around the $650 mark.

Andy, I"ve got my gq coming in on friday do you put these injectors in as a standard replacement?

We only do standard replacements unless specifically asked for or that we think its necessary. You have to have a lot of revs and fuel delivery to need them, as most of our 130-150rwkw patrols dont need them.
