View Full Version : Question on piston/liner sets

09-02-2009, 11:36 AM
I starting losing oil pressure last week in my TR3A and after pulling apart the engine, well it's time for a rebuild. Here's where I need some help. I want to replace the piston/liners and and here are my choices:

Mahle 87mm
PowerTune 89mm
XRN 89mm

Both the PowerTune and XRN are made in England.

Has anybody had any experiences with these products? Good or bad I would appreciate any feedback before I buy. Thanks.

I have a set of Mahle 87mm in my TR3. The Mahles are made in Germany IIRC. I don't have enough miles since the rebuild to judge the longevity quality, but the fit was very good. The standard size Fo8 gaskets brought the liner protrusion right at spec.

I fitted a set of Mahle pistons and liners 20,000 miles ago. They fitted beautifully and I have not had any issues with them.
