bluliz Posted October 20, 2012 Share Posted October 20, 2012 Anyone have any details on ST170's with superchargers or turbos? Essentially does the Dual Stage Inlet have to be replaced when doing the above? Any way of keeping the Variable timing? anything else I should know?

Stu Posted October 20, 2012 Share Posted October 20, 2012 I wouldn't use that inlet or the vvt. All leads to unnecessary complexity. What do you want to achieve, Rob? Link to comment Share on other sites More sharing options...
james08 Posted October 20, 2012 Share Posted October 20, 2012 yes the inlet needs to be replaced, try area six i think ian howell makes them you can keep the vvt and it gives more power if kept, if you get rid of it you may aswel just get a 2.0 zetec and turbo that if your interested i can get a jackson racing supercharger, pm me for details on it Link to comment Share on other sites More sharing options...
Ahmotorsport Posted October 20, 2012 Share Posted October 20, 2012 I wouldn't keep VVT with forced induction. VVT increases the valve overlap, this is great on normally aspirated engines because it increases the air speed into the cylinders. Its bad for boost because both valves are open at the same time, for longer, so all that boost you've built up would just be blown out the exhaust.

james08 Posted October 20, 2012 Share Posted October 20, 2012 i know it does work with a turbo engine as i know a st170 that has kept it thats currently running around 400bhp, built by torque of the devil iirc, has a head built by area 6, ive got a fair bit of the spec somewhere for it as im building mine to a similar spec Link to comment Share on other sites More sharing options...
Stu Posted October 21, 2012 Share Posted October 21, 2012 VVT does not give you more power. It's all about low load driveability and emissions. Link to comment Share on other sites More sharing options...

What do you want to achieve, Rob?Something a little more fun to drive, essentially I've had the car 6 years and love it but maybe it's time for something else. yes the inlet needs to be replaced, try area six i think ian howell makes themyou can keep the vvt and it gives more power if kept, if you get rid of it you may aswel just get a 2.0 zetec and turbo thatif your interested i can get a jackson racing supercharger, pm me for details on it Exactly. There is part of me thinking a scruffy looking KA with a 2.0 turbo would be more fun.....See what position I'm in when I sell the house. but then I'm also a fan of big power diesels...

Stu Posted October 21, 2012 Share Posted October 21, 2012 Time to get rid Rob and buy something different A £3k impreza classic with a couple of subtle mods would be night and day fun compared to the stress and hell of building a turbo focus (and subsequent poor useability).

They've got no poke. Link to comment Share on other sites More sharing options...
Stu Posted October 21, 2012 Share Posted October 21, 2012 Perception means nothing when you get owned in pretty much any situation with a corner. Link to comment Share on other sites More sharing options...
