Hello I'm new to this so was looking for some help! The bottom end has gone on my 93subaru turbo and I don't no where to start looking for another engine Any ideas. 

There's always a risk with second hand engines especially if they're over 20 yrs old . A rebuild will cost £1.2 k in basic parts and machining costs, without labour and a new crank ect .

If you decide to buy second hand....

Any v1 92 to v4 98 long engine (bottom end and heads) will fit if you fit your inlet manifold and auxiliaries to it .

If you want a straight swap (leave the inlet manifold ect on ) get a v1 92 to v2 early 96 complete engine as this will drop in.

If your not intending on mapping it afterwards try to get a engine out of the same model , cos cams differ on the sti models .

Best of luck and let us know how you get on.

If it's not broke .....upgrade it 😊
