3 Rotor, What would you need :)

Im sure kev was saying that the 20b is seriously restricted on the stock cosmo to hold up to the max bhp agreement. If you run a free flowing exhaust system and ecu then you get way more that the stock amount

very true,  they even run the same exhaust sleeves as an egi but you would really need to run an ecu minimum so you can fuel it accordingly.  If you are going to fit one, port it and fuel it even if you run the stock twins.  You may see 350 - 400 rwhp but you can get that out of an old TII engine.

Right to clear up a few of these thoughts you guys Have. Stu the 20b ecu is much more than a engine ecu if it doesn\'t see the correct response at for example climate control inputs exhaust changeover valve and countless more it will default to limp mode. It has been done twice as far as i\'m aware but is a major wiring nightmare. The Gentlemans agreement in japan was to limit bhp to 300hp the Cosmo was restricted with this in mind but they still failed and most saw about 330hp from the factory. To try and restrict them there is the killer MAF sensor that blocks the intake, exhaust sleeves that close aprox 50% of the exhaust port a very restrictive exhaust system plus the addition of three catalitic converters. To put into context how much power the 20b will develop with very little modification i was running stock exhaust sleeves more or less stock ports and only 0.9 bar to get 476rwhp last year.:3gears-rh

so in theory you could run stock turbos and stock fueling with a mappable ecu and custom exahust??
thats where the big bucks start coming in ie exahust man,porting, turbo,injectors,fuel rails, downpipes etc etc.
I would spend 5000 on a crate motor and run it stock with an ecu if its possible to get 500 hp.
to do list- radiatior and front mount fabbing, fabbing engine mounts,mounting 20 b on fd bellhousing what else??
