I know the standard is better brigade will have me hung and quartered for this but... my dad's just purchased a my02 wrx which for the majority would be more than adequate, but my dad wants around 350-400 bhp
and before I get jumped from the likes of pslewis, this is for track use, but also it will be a road car, so what would be the best engine tuning for maximum reliabilty as well as power, and how much would it cost?

 

I would say:

£1300 - GGR 2.5 Bottom End
£1000 - ECU & Mapping
£500 - Full Exhaust
£400 - Uprated Manifold
£700 - TD05 18g (estimate)
£500 - Fuel Pump, FPR, Panel Filter & Any other wee engine bits
£1000 - Replacement Brakes (AP, Brembo, etc)
£800 - if Bigger Wheels needed to clear new Brakes
£1000 -Suspension & Handling Upgrades
£500 - Defi 3-Gauge Set-Up

Total staying as a 2.0: 6,400
Total going for a 2.5: 7,700


There could possibly be other things that are needed to get to your target BHP level, but thats all I can think of just now.... It will be much easier to achieve 350bhp on an engine professionally spec'd around the 2.5 bottom end. IMO.

thanks mate

 

£1200 for a FMIC

 

AP kits are £1500 plus
motec, gems, links are £1k-2K plus mapping ( depending on ecu model )

 

Hahaha, ok gays.. I mean guys, I did say I might have missed something!!

I was thinking of an Power FC when it came to the ECU as I believe thats enough to run a reliable 400bhp, proved by AndyF.

The prices arent including labour either, to be honest, I dont think you'd be more than a kick in the pants away from £10k for a pro built 2.5 conversion & supporting mods.


Cheers,
