I'm about to go go through a few upgrades on my 97my v3 Impreza wagon 2000 turbo I'm putting on an
Apexi power fc
Fmic
VF28 Turbo
440cc injectors
But before I start all these I've been looking around will I need a different MAF sensor and also a higher boost cut or will the apexi take care of this also can I use my OE recirculating dump valve system because I'm not a big fan of the dump to atmosphere valves if i do have to have one can anybody suggest one that isn't too loud

Many Thanks
Dan

 

I use a forge recirculating valve on mine, it's fine at 1.5bar.

We are assuming you have already sorted brakes and suspension?

 

Cool cheers mate yea I'm already running 4 pots on the front std calipers on the rear but with ebc yellow stuff pads and up uprated shocks and white line springs lowered 25mm

 

Dooooooooooooomp valve adds 50 bhp.
Have you got one of those self learning ecu's too??

 

Don't be tempted to lower any more, it feks up the Scoob handling, you'll find the car will roll MORE on corners if you do.

 

It needs to be mapped but before it can go I want to make sure it is going to be ready so the mapper hopefully has no headaches

 

I wouldn't lower it anymore anyway. Plus the size speed ramps round my way are ridiculous

 

Power FC is old tech now, Dan

You'd have been much better off with the ESL board, unless you got the PFC for next to nothing.

Anyhow, a lot of people used to, and probably still do, use a Z32 MAF sensor, from the Nissan 300 ZX.

What colour are the injectors you already have fitted?

 

It's got the std grey 330cc injectors in it at the mo and I did get the Apexi cheap my ECU is the 3 pin 8s ecu in it in total including mapping the Apexi will be cheaper than an ESL board fitted and mapped

 

You will lose a massive amount of functionality;
