What is this Broken Pipe near the injectors on my EJ18


Recommended Posts

I was trying to pull out the Coolant Temp Sensor and I noticed this small broken line/pipe coming from a little pump thing on the end of the Injectors Rails (if that's what its called???)

 

This is on the left side of the car (standing in front of the engine bay) Drivers side in New Zealand.

It comes from out of the top of the little pump thing and goes up into the intake manifold.

I only noticed this now and I may have broken it while trying to pull out the sensor, but would this being broken stop my car from starting?

Berg, I ran my EJ18 in my old L with 12 psi on leg ss injectors (370), Walbro 255 pump, and SAFC-2 for about 6 months and right before the wastegate failed the compression was still 130's. As the wastegate failed the boost spiked to 20+ psi almost instantly and the only damage that occured was a few broken ringlands on the pistons. The NA EJ motors are super tough! When I swapped it out to a junkyard EJ22 it was a little harder to tune because of the restrictions of the 1.8 ecu but it still ran pretty good and had very little detonation but still no problems.

 

But get this, after finding that my fuel set up couldn't efficiently control the 6-7 psi I was running I dropped it down to a 3.5 psi spring in the wastegate and got it tuned out alright. But even on 3.5 psi with a wrx turbo, big FMIC, and 3" catless exhaust on the 2.2 it managed to beat my WRX!!! It would spin all 4 tires right of the line at the track and give a good chirp into 2nd!

 

I raced the kid that bought it out at RMR when I bought my WRX and he had the same set up still and he ran a 14.9 and I hit a 15.1 in the rex.

 

The WRX turbo is a bit undersized for the big 2.2 and the higher compression but it would spool 8 psi under 2800k rpms. Which would make it the ultimate set up for rallycross!

 

So I guess to answer your question, if your motor is in good shape and has good compression then you should have nothing to worry about! I would ditch the WRX wastegate and weld an external onto the up-pipe so you can adjust the boost safely below ~7-8 psi. But those motors can take the abuse!!!
