same weather but when engine is cold, high boost when warm , it can't go beyond 7-8psi

 

look at these scum bag , there is a reason worrying about my baby 

 

Where's the abuse? Road testing with very conservative driving.

friend of mine had its car totaled by a dealer here who was meant to service it .

 

a 19 years old took it out and trashed it who was a technician

 

a question re link ecu, I installed new turbo and wanted to take the inlet manifold out to paint it.

whilst doing it, I realised how much of a pain it can be to even change the injectors so I have decided to get the 630cc injectors and install it and take it to tuner.

 

my question is, if i simply plug the g4 into the car, can i change the injector size and then the base map will inject correct amount of fuel or no ?

spoke to Link tech and was told I could change the injector opening time to half which would allow the engine to run on the 630cc injectors and can slowly drive it to tuner. thoughts?

How do you plan on doing that? Is there an Injector open time table?

A proper tune will never take ~3-4 hours unless your tuner already has a canned map, your car is perfect, and they just need to verify that everything is running properly + maybe small tweaks here and there. It will take a few days to do it right even though Link or whatever ECU manufacturer of choice is providing the base map which shouldn't be too far off in the first place.

OEMs take months of engineering time to do the factory calibration. It's a full time job. Even then sometimes they run out of time and it's too late to get another calibration emissions certified and you end up with a factory tune that breaks engines. Subaru has done this before. With a turbo engine especially the dyno cannot do everything for you, some road testing is needed to tune for real-world IATs.

Engine calibration is not for kids. If you don't trust your tuner to not crash/abuse your car they have no business doing an ECU calibration.

Some logging is needed to diagnose why your car is running wrong on the base map, if you can screenshot a trace of the behavior people can probably help.

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
