The seals have gone on my turbos so it is time to repair or upgrade. If I'm sorting the turbos it would be nice to get some more power from them, I don't have the cash to go single so what options are available and at what costs?
Options I can think of are;
Replace seals, no HP increase - cost?
Swap turbos for Whifbitz hybrids, up to 440bhp - cost approx £2k including fitting (with Whifbitz)
Swap turbos for Turbo Technics turbos, up to 480bhp - cost £685+ VAT (assume this is per unit without fitting)
I am a noob to turbos so please excuse the simple thinking if I'm just picking on the pub ammo stats. The Turbo Technic units seem like they are better as they can handle more power and boost pressure.
One more beginner question; I know you need to upgrade the ECU for fuel management, can a boost controller completely control the boost pressure, so you wouldn't need a restrictor ring?
So what are everyone's opinions and what other options are out there?
