If got budget, K3VE-T or the new Myvi 1.5 transplant.
If not much budget lighten the car, take out whatever unecessary deadweight in the car, replace with carbon fibre, drop in airfilter (or open pod if manual) with heat shield, pulleys, lightweight wheels and engine management.
If really little budget drop in airfilter / open pod and pulleys and lightweight wheels.
If even less than that budget, save up your money for the above.
We had a mega gathering of RX8's over the weekend. 52 RX8's in total gathered to be apart of this momentus event. We'd like to thank ST Wangan, Hypertune, and Italiannies for your support.
when dis happens my rev feels like a pull back, drop of performance for 1 sec,,,, on dyno machine at each run, it always happens at dat region, thus im not able to pull above dat region, as da a/f ratio fluctuates up...
