    Yeah that compression would be fine. I seem to remember Robo's is up around that number, he just had to run 7 degrees of base timing instead of 10 .. unless you plan on cams.. which would be awesome.

    Oversize Toyota pistons fine?

    Worth balancing crank and running lighter harmonic balancer? Like about would like to go 27x cams later. stock ecu..

    only if the limiter gets sat on alot as in drifting but as for racing i think it would be fine and as for the compression i think the more comp the better allows for upgrading the head later and the more comp you have the more efficient the engine will run there is power to be made just in upping the comp lok at smallport compared to bigport 86kw at fly to 100kw at fly cams are the same duration only major difference is the comp, intake ports and ecu
    the dyno pull to 300rwkw

    BT20v is making 300rwkw like i said i would without nitrous so now its time for some spray and see if she will run a 10s or less

    you wont sit on the limiter with a 7a, at least a basic one (stock ecu/cams). there isnt much up top! goes hard through the mid-top though

    Cam's would give it more power up top, so I would be up there more I think.

    People post up their setups!
