Some engine advice please

I have a UK turbo classic

Andy Forrest mapped ecu
Front mount intercooler - just put on friday
Boost turned up
HKS mushroom filter
HKS dumpvalve
silicon hoses
Samco intercooler hoses with mikalor clamps
GREDDY clutch
Hope i havent missed anything

Just bought a boost controller
Air/Fuel ratio gauge

My mate said to me about a Fuel pressure regulator - Should i have one of these

Any advice would be great on where to go next for more power

Bigger turbo, and higher flowing injectors will see you well over 300. Check Andy's website for an idea of what can be achieved. I think it was a VF35 turbo he advised me to get if I wanted to take the next step up. I'm sure the injectors only support just over 300bhp IIRC.

Why do you need a boost controler if you have a re-mapped ecu? Surely the boost is controled via the ecu?

Walbro, 440's and a turbo. The VF series works well. I prefer the VF28. It'll see you over 300bhp, spools quick and is as cheap as chips.

Should be around the 320/320 mark with that lot, staying with P1's and caning standard STi's.

A boost controller is an excellent idea on a classic shaped impreza as it will give better acceleration. I have an AVCR fitted on mine
