What engine do i go for?
 

I have a Jap import STI V5, but the big end went on the engine, so have been told that there is damage to the block so it needs a replaced bottom end. Part of the problem is that this happened in Inverness, as such the only choice i had was a mian Subaru dealer, who although helpful said they cannot give a garuntee with the engine cos its not a uk car.

The problem is they said they can supply and fit a new P1 bottom end, which is the same as my STI one. However is this going to be the best option?

As i will have no garuntee i could go elsewhere for an engine, as i am reluctant to put in another engine if its prone to do this again. Would getting a 2.2 or even a 2.5 bottom end be stronger? would the turbo need changing as currently its a VF28 and will i need a different ecu?

TBH i dont really ave a great deal of knowledge about subaru engines so any help would be appriciated.

best to speak to David @ API

Subaru will charge you a fortune, and no g'tee!

would advise getting it mapped to suit uk fuel anyway, even if you keep the 2.0, and yes, you would need it mapping for 2.2 & 2.5 conversions

the turbo should be ok, and would come in earlier on bigger cc engines.

I've just had a similar dilema, big end issue with an STi3 (although no main dealer involvement). Pondered about a rebuild, but instead got Paul @ Zen to build me a 2.5 using a new short block :) There are a number of good places that will do it for you.

I'm sure if you ask on the Scottish forum here or at www.SIDC.co.uk you'll get pointed to the best specialist local to you
