i would suggest keep the NA for the genesis-8 with high-revving. by some port(only can be done in Jap , i guess..), changing some gear ratio & ECU upgrade. potentially approx 210whp. Turbo or super charge is good, but most of local tuner didn't change the high performance apex seal for their customer...mayb they dunno how to do kua...
changing to rx7 13B oso not a bad idea tho...![]()
210HP can only happens to manual....... Renesis intake port is bigger than RX7's but exhaust port is smaller...... It almost reach maximum porting size, slight porting is possible but don't expect much gain...... As for apex seal, there was no aftermarket apex seal for RX8, but you can use RX7 seal (need machining)...... Rotary and turbo are perfect match, turbo increase volume efficiency.....
13B conversion on RX8 has been done in US, Aus n Japan...... But no local workshop is good enuff to do this conversion ....


i'm using Pan-speed ecu last time...
