MX-5 performance parts, suspension, shocks, superchargers, turbochargers, exhausts, brakes and servicing

Our testing and development of headwork have proved there are good gains to be had by working the stock head. Although not complete, initial results on a 2001+ head with 1mm oversize valves are very encouraging.

Refreshed Head

For those not wanting the expense of full head work, P5 can refresh your current head with the following work undertaken.

Pressure Test
Measure for warpage
Skim
Cut valve seats and valves
Clean ports and bowl
Full hot tank clean

Please note, the work does not include removal and installation of cams and valves, nor shimming the 1999+ solid lifters.
