sneakin like he said if he wants like 400rwhp...what kind of compression would be necessary?..i know on hondas going upwards of 12.1 all motor is about the limit for 93octane with a tune of course..u think thats managable on his car..maybe 11.5:1...or would u use stock comp pistons and do other work??...it is daily driven but i know he wants some more hp out of his car...thanks for the info...
