Engine code is FS-DE detonation with the MSP shouldn't be a problem since the ECU is programmed for turbo. With a Spool stage 3 system you can get 198 whp with 6.5 psi as for the itty bitty T25 on the MSP no one really knows they dynoed a dissapointing 138 whp i think so there is much room for improvement,. Acording to Mazdaspeed the stock rods buckle at 225whp but that level has been reached and sustained with no problems. SO the limits of this motor on a turbo is still not yet known. The Cranks are known to be good for 400 hp from the FS-DE's that were in the Ford probes. As for the rods no one really knows that one. They are a solid motor though. But they are right if your gonna buy a car reasearch it before you but it man...
