What bhp does the IHI make, and what are the extra components needed?
IHI typically puts out around 320-330bhp and similar torque (it could have more torque but you will bend a rod)
what are the extra components:
Stg3 clutch £400 ish
FMIC £400 - £700 ish
Exhaust - £500 if going turbo back
injectors - £200 ish (2nd hand I believe)
uprated fuel pump £70 (dependant on tuner)
4bar fpr - £35
Manifold - £500 ish (standard manifold cant flow that much)
Air filter (anything from £70 - £200)
Forge 007p £80
power will be pegged so you dont ruin the internals
engine mounts are recommended as well
these are highly recommended, due to the extra power and movement from the engine, if the mounts are not uprated then it causes too much movement and flex on the downpipe, leading it to crack, this in my opinion is a must
engine mounts are about £150 high density ones from INA in the US
I think that is it
OH and plus fitting and mapping time ££££££££££££££££££
OH and the turbo of course
£800 ish
