I guess its sort of ball park. Im more around -9psi, so -6 means your pulling less vaccum. Possible vacc leak

rear o2 is fine wherever, it should be after the cat but yea either way it will work, just make sure the front o2 is right after the turbo

Damn this is a long thread lol. I have worked with some different motors and I know some guys that run 207's and they love them. Their only complaint is the lack of TQ from the 207 vs a 2.5L. So from their own mouths if you want TQ and good track numbers go with a 2.5L if you want uniqueness and high reving top end power then 207 and have fun. And for Non STi owners go with a hybrid build, just make sure to get the right head gaskets to support your heads along with the other supporting mods based on your engine build. Reason being that your ECU cannot support ACVS so you would need to go with a stand alone and spend a ton more money for not THAT big of an advantage. If you want a big turbo power low end tq set up and great numbers the 2.5L is the motor for you!

Hey guys went to go check out an ej207 and when i did the leakdown test with 90psi in put pressure the back two cylinders closest to the the firewall came up 83psi output pressure so they were leaking 7 psi. The front two cylinders wouldn't hold any pressure even at top dead center. So while filling the cylinder up we thought maybe it was on the exhaust stroke so we turned the crank over and nothing happened. Both cylinders were like this. We also noticed the one spark plug had no oil on it and was rusty on the part inside the engine. Im going to guess the intake valves arent sealing properly and all the air is leaking out the intake manifold. How hard and expensive is it to fix this? Any reccomendations im trying to work out a deal but want to know what im getting myself into first. Thanks in advance

Depending where the leak is coming from will determine how far you gotta tear it down which will determine how much its gonna cost to fix it. At minimum your looking at bent valves, so "just" a s head rebuild... at worst your looking at a trashed bottom end (fried rings at best, cracked ringlands at worst), so you'd be looking at a complete overhaul. def |

I've been spending time over on scoobynet, and I had a question about some things.
They mention that the ECU is limited to 1.55bar (22psi) and in order to go higher the tuner has to remove "safe guards" ..... which they say is a big "no no". But when I look at most of us here in the US..... with the JDM ECU we are pushing 25-30psi on the stock ECU in some cases. It might be they are just referring to the EDM ECU which maybe has a lower limit vs the JDM. Def curious to here the rest of your thoughts on this. Looks like I'm going to go with the SC46 (blouch) since in the end it is about the same price as going with the Litchfield LM450. If I go with Blouch it's $1595 and I have to send them my VF37. If I go with Litchfield it will cost about $2500 with shipping but I keep my VF37 which I can flip for $700-900. Plus I haven't noticed much difference in power when comparing results from diff people. I do like the billet wheel on the SC46 though. Decisions decisions |

they may be talking about the absolute "boost cut" limit which can be changed in the ecu.

The boost cut or the ecu is not limited to 22 psi. Its only limited by the tuner that tunes the car and the tools he uses.

I looked into it some more, looks like the JDM ECU can read 1.7bar vs the EDM ECU's 1.55bar. Sounds like the ECU's sensor can't read/register anything over that, so to boost further you would need an MBC which removes the ECU safe guard of it knowing the boost.

Incorrect. You can set the boost cut to well over 30 psi.

In the factory rom file, that is how it is setup. They dont know how to tune the rom so they just say this is the limit.
