You'll need only the heat exchanger if you plan on staying at 8-9 PSI.
If I could do it all over again I would have stayed t 412 WHP and be still driving it and not looking to buy another one  |
Same boat as you, my kit was just fine at 430WHP and then when i upgraded the kit, motor gave out at 510WHP (ran meth as well), leave the kit alone and enjoy the car, the extra 50-60hp not worth it for the amount of the long term headache you will go through TRUST ME!
