No fair! I want a Koyo Radiator and FMIC....if I at least upgrade my radiator, how much boost can I run on the stock seals of an S5 J-Spec motor with about 40k mileage on it?

i wouldnt raise the boost on just a radiator upgrade

Happy Easter everyone. What a coincidence, I just got off the phone with a friend that told me he got a 350 last week. He has know idea I'm getting an FD next week which once i get running properly will **** on his brand new track model! Nice kill dude. https://www.nopistons.com/forums/pub...#>/biggrin.png

If you think the radiator has anything to do with how much boost you can run, I would take it to a rotary specialist and have them guide you on what you should do to the motor. It'll help keep the engine cooler under higher boost, but that's about it.

Recommendation mods for more boost:

More fuel - fuel pump, ecu, injectors, etc

Internals - 3mm apex seals, street port
