[birel23]

alright guys i need some help here i have a turbo 2.7 engine used for track events. i use to run sc cams when it had cis on it and they worked great.i tried group 'b' cams and it would not even build boost after installing those! im freshening the motor now and i have changed a few things. its a 2.7 low compresion,mfi ported heads with 40mm intake ports and 38 exhaust it has mfi intakes that have been converted to electronic fuel and spark via electromotive unit.twin plug. the intercooler looks like the older 935 air to air unit that sits on top of injectors. it has equal length 1 &5/8 headers with twin 996 turbos. i dont want to rev over 7200.got any ideas? i was told to use 2021's but not sure.i dont want to make the same mistake i did with the group b's again.
