Good Afternoon,

I have been spending almost all day searching and researching various forums and have decided to start here with my questions.

I was approached by a friend of mine yesterday who picked up a 92 turbo hatchback last weekend. The car is not running properly and I am trying to help him figure out why.

Here is what I know as of right now since I haven't really dug into the engine yet...

The engine is a D15B2
There is an upgraded ECU of some kind...I will report back with what it is later
255l Fuel Pump
T3/T4 turbo from a volvo S40
VAFC Apexi A/F Controller
Turbo Timer
I have yet to determine if there is a FMU at all.
Manual Boost Controller
Fuel Injectors from a Honda Accord (I don't know the year yet)

Keep in mind I have only looked at the car for 10 minutes in the dark last night.

The car is running very rough, sputters and it looks like the boost controller is not working which is a good thing because the way this car was pieced together the engine would be blown if it was working.

Everything I have read to date tells me that using a VAFC and FMU with this setup is garbage. What I want to do is first figure out what the hell has been done to the car. It appears the conversion has already been done from DPFI to MPFI but again, I will confirm that later.

Can anyone help point me in the right direction of what to look for or give me any pointers?

Any help is appreciated.
