i think you should read up on the st engines block weakness. You may find the 2.3 engine from an 850R or V70R will be stronger.

Will be great to follow your project, stand alone engine management might be a lot easier than trying to incorporate the ST wiring?

So will you be cutting out the bulk head for the engine to fit in the bay.

ST blocks have been known to crack even at standard tune, but some have run well over 300bhp without issue. Pot luck.

I'm using vipec v88, it allows up to 12 cylinders, where as the v44 only 4.
Just search the internet, for the wiring, you will find it.
I still have the original ecu if it's any help...

Got any photos?
