Thinking my PCV valve is clogged or stuck based on how my car behaving right meow. Is the v7 PCV valve the same as the 02/03 USDM 205? Or is there a specific JDM part number I need to find?

I'm leaning towards swapping EJ207 into my 2005 WRX. I've considered short-block builds but would prefer to avoid the long break-in period since the car is mainly used for RallyX.

Is there anything I should be aware of when looking at V7 engines? They're getting up in age and inventory is low but I think they're more reliable than EJ205 swap for my needs.

I'm open to any suggestions!

He may be looking at a v7 in order to stay single scroll.

I would say that's ultimately going to based on budget, and at the very least if they can get a verified compression and leak down test... Won't make a difference if you go single or twin scroll... Minor things needing swapped

Choose wisely, do you already have a good turbo and turbo back exhaust you want to continue to use or are you looking for an all new setup ?
Do you have an Accessport you want or need to continue using or do you want to run on a jdm ecu with functional avcs and open source tuning ? Are you setting up a street/track car or street only, track only ?
The direction you need to take is based on many considerations, including budget.

Question Nuetral Safety Switch Polarity V7 EJ207 2004 WRX

Hello!

I recently completed dropping in a used V7 EJ207 into my 2004 WRX. I have been following this EJ207 info thread which has been amazing help! I'm getting ready to start up the car. But before I do, I wanted to make sure the Neutral Safety Switch had the correct polarity. I'm a little confused on how to do this, and how to change the polarity if I end up needing to. I haven't used Romraider before. Is Romraider the only method to check the polarity?

My thoughts are that I'm overthinking this polarity thing and that all I have to do is cut the wires and just swap the wires around.

More info:
- Manual 5 speed
- AVCS wiring is installed
- The car has a remote start installed.* (Im assuming this affects things)

My understanding from what I remember from back in the day is NSS is reverse vs usdm. But everything else is the same.

Donít cut anything. Just de-pin the 4 pin for 5MT or 6 pin for 6MT

You should be able to hex edit the ROM. This dependent on the ROM you are using. I did it for mine, v9 spec c into 2004 wrx 5mt. If I recall Romraider doesn't have a toggle for it hence the hex edit. Also, I think the problem is a NO vs NC thing, not polarity. If it was me I wouldn't cut or depin anything you can do with a simple rom edit.

Start here and search for NPS on the Romraider forums: https://www.romraider.com/forum/view...p?f=15&t=10794

Thanks guys! Iíll see if I can do it my selfÖ Iíll need to get a tractixs cable and RomRaider. Then learn how to use it because Iíve never used it before! Lol. But regardless I should learn how to use RomRiader since my Cobb wonít work with the ecu anyways.
