I have a jap import evo 7 that I was told is stock.

I ran it on a Dyno recently and got 163kw/222hp at the wheels. I also had a average of 18 psi and a spike of 20 psi.

Are these stock numbers and are they normal for Evo 7 that's 12 years old.?

Maybe it's a ECU tune change, but I'd like to know if it's normal.

 

Stock boost is 18psi, it's likely to tapper down to 16psi by red line.
It would be a good idea to examine the wastegate.
Check for boost leaks & measure engine compression.

What's the mileage on the car?

 

I checked the Compression around 3-4 months ago when I purchased the vehicle.

It's currently got 150,000 km's on the clock.. I know it's alot compared to others, but I am restoring it as best I can. Services/replacing everything before modifying for power.

 

Yip that sounds about right, maybe a little low from the normal but not by much

 

Install a new fuel pump (ex. walbro 255).

 

18 psi is stock for evo's

 

I actually have another thread about just that! sadly, no-one has been able to give me any help yet.

I purchased a Walbro 400 because I have plans to go further then the Walbro 25 can take me. Just unsure if it's so overkill it could do damage..... LHP vs it's PSI ****...

Please read, comment and save me! haha

255 & 400 are max capacity numbers (400 liter per hour) having a bigger capacity pump is no problem at all!
40psi is the stock pressure, so you should be fine :]

 

This is my stock 7. 18psi dropping to 16
