Buying an Impreza shell

Featured Replies

Just wondering is it a lot of money and work to put an engine into my 1998 Impreza sti shell?if so what engine would you recommend?


@savagebulldogs is your man to ask in the in's & in outs of reshelling,

I guess a lot of it is time

depends on engine spec as costs will vary based on that, closed deck block, fully forged internals, stroker kit etc. As mentioned Savage has a great build thread for his classic - step by step could you rebuild your own unit?

It's not too bad really if shell is good

Cheers lads


Main thing is to decide what you want from the car once it's done (daily driver ,track toy or oe spec)

As @ 330hp + it gets expensive, forged build, bigger turbo and drive train upgrades won't leave you much change from £4k ,even if you do all the work yourself .

Do you know what version impreza you have ? As this will help us know what version engine will be a straight swap.

If the coil pack is in the centre of the inlet it's a v4. if the coil pack is to one side it's a v5 .

The main reason I reshelled mine was because of the rear arch and suspension turrets had rotten away .

Is it a clean shell ?

As the last thing you want is to spend time n money on a cars mechanicals to only find out it will fail a mot due to rot .then end up spending another £1k getting it back roadworthy and looking good .

If it's not broke .....upgrade it 😊
