Don't buy Deatschwerk injectors.
 
My deatschwerk injectors just failed a little over 2 years causing misfiring. After checking the code it came out to be cyclinder 1 misfiring, changed the coil pack and the spark plug to another cyclinder, same misfire in cyclinder 1.

I called the tuning shop I frequent Hill's Garage in Baltimore, MD(which is an awesome shop and one of the best around the area) and told them I think my fuel injector just went. They told me to bring it in and told me that lately a lot of the Deatschwerk injectors have been failing. They ordered a set of new injectors from them for another car and the injectors came in a Deatschwerk box but they were Bosch injectors.

Long story short try to go with Bosch or RC injectors, I'm out 1k because of new injectors and needing a retune.

yah, Had a set of 460cc Deatch injectors on my RB20 a few years back....one got stuck open under hard acceleration and hydrolocked the motor....filled the cylinder

I've never used them but it seems like these guys have got some work to do. It takes a shorter amount of time for bad news to travel about a product than good news.

Just find GTR injectors...570cc and usually cheaper than aftermarket

my tuner says the same about RC. what percentage duty cycle your injectors running at?

Wish I knew about this, already ordered Bosch 550cc Bosch injectors.

there re drilled stock injectors... hence why there like the only plug and play and are cheap... i had a set for a 300zx, you can noticeably see the re drilling, and i actually pulled a shaving from one...
