As more and more r53's are becoming 'Turbo'd' ..there is a need for a Ported Head to cover the Heat and abuse. Stainless steel Nitrate coated, single keeper Intake Valves, and of course the Inconel Exhaust Valves!! ready to take the heat. Bolt on ready for : $1995.00 Dont forget that with the Ported TPR2r(T) Head, the next restriction is the Standard Intake Manifold. Thumper Performance can help you with that also. Ported I/M for $275.00 See: Thumper Performance | The OTHER MINI Head! or Auto X Cooper Thanks Thumper (note: core fees apply see website.)
Keep in mind we do 4 series of Ported Heads to fit any needs. r50 - r53 heavy street - r53 Aggressive street and some track - r53 more track than street.. and of course the TPR2r(T) turbo.. We can 'Custom' Build the Head to your needs/ Headers / Intake ect... Thanks Thumper
