rb20 all the way. Are aimed power figure is 400hp atw. With the porting(isnt much clearance for porting compared to the rb20), polishing, and the gtr cams.. will give a greater puff, and longer puff duration. ie, earlier spool up times. Being a ball bearing setup.. hopefully knock 200 rpm off... We are not the first twin turbs rb20, there is another here in brisbane.. but the are using much bigger turbos.. and the characteristics everone are describing is the problems he is having. our misson goal is always, because they say it cannot be done.. means we can do it.
Our other project car is a barina swing. 1.3 liter. ~18~20 sec quater standard car. We told the public of brisbane,this is going to be a 13 sec car when finished. The amount of people who laughed in our faces... all they can do now is just let their jaw drop when they see the car in action down the quarter.
