Engine 3.8L, 102.00mm Bore, Ductile Iron flanged liners (With Hole and cutouts machined)
Fits:
Porsche 991 3.8L MA1 Engine Only Price SET OF 6
Porsche 997.2 3.8L MA1 Engine Only Price SET OF 6
NEW Ductile Iron cylinder liners suitable for repairing damaged Alusil bores in 991 engines.
These New Ductile liners now have the cutouts and gudgeon pin hole already pre machined into the liners. The liners will only need to be bored and honed after fitment.
These liners are becoming very popular, with increasing numbers of cars suffering from scoring in the bores.
The liners will need to be fitted by a professional machine shop. You will not need to get special pistons or rings, as the original spec ones can be used with these Ductile liners.
Fitting guidance:
Interference for the liners
into the block is 0.038mm +0.0127 / -0.000.
The liners need to be
cooled/frozen and the block heated.
Make sure that the bored
finish on the block is very good, maybe honed before fitting the liners.
After the liners have been
fitted and the temperature equalised, press the liners down to make sure they
are seated on the flange.
Bore and hone the liners to
the correct piston size, then press the liners again to make sure that they
have not lifted a small amount (This can happen).
Now face the block completely flat.

Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR069, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.
Kit includes anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Also includes our SR065D drill guide.
