Engine is at machine shop being sleeved w/ darton solid decks and bore & honed to 84 mm
Correct me if im wrong--84 mm is far from to big for high boost...
Just trying to clear up rumors or get opinions
Im sayin

 

should be fine.

 

I know RS Machine and GE sleeves as well as Darton are fine up to 86mm maybe beyond for All Motor. 84mm is about the largest I would run on a high boost street car. It isn't necessarily needed. A lot of guys are all about the 82-84mm bore. Yeah it's good for a little quicker spool-up and yeah it will make a few more hp at at certain boost levels vs stock bore, but personally you can make plenty of power on the stock 81mm bore plus you have a lot more room to work with should something go wrong, little safer as well. Just food for thought.
