Thought i was getting the semiens injectors, instead got 60lb edge ones. long in size, i have todd kit for the retrofit of long injectors. should the injector go into the manifold very deep ?

 

The Edge 60lb injectors are Semiens. Same length, same flow, etc.

There are a few reasons why we aren't using these injectors on the 996 any longer and fitment is one of them.

 

What injectors should be used instead?

 

We're using a variety of Bosch Motorsport injectors. 58lb most commonly.

They are nearly drop in, have a great spray pattern, operate with very similar characteristics to the stock injectors and are very similar priced.

 

I had 3 sets of injectors and all were long.... with the adaptors it seems like a direct fit...

 

i agree with mark , no issues with the siemens 60lb .

 

okay, but please elaborate on the fit'ment. It seems to us that the 60lb'ers are a little too easy to remove, verses the stock ones that are solidly locked in.

 

I have not done the installation myself. From talking to others who have done it, the Siemens 60lb long injectors have more play than stock injectors. The trick is to make sure the rail is properly spaced and tightened down, then they will be secure. As always, check for leaks.

 

how would you check for leaks after install?

 

Just fire her up... you will soon know if there is a leak... especially when she's warmed up

 

i agree with nick and mark... never had a problem...

 

okay, but tell us more about how to find leaks ?

 

Turn the key but dont start the car. The fuel pump will prime and pressurize the system. Look for leaks and smell for gas. Repeat several time.

You can also run the pump using a Piwis or similar tool.

 

and have a little dental mirror and a flashlight because if it leaks, it will leak where you can't see it!!!

 

HMM, okay guys this will test couplings, but not pressure leaks ....
