JE 4.125" custom forged pistons - Porsche 944/968 turbo 3L+ hybrid stroker 8V
$400 shipped
For sale is a set of (4) brand new / never used or installed custom JE 4.125 forged (4032) pistons for a hybrid stroker 3L+ 8V. Great website for details: Refresh951Â*Â* lÂ*Â* Porsche 944Â*Â* lÂ*Â* Porsche 951Â*Â* lÂ*Â* Shawn Deal These were designed/custom built for use in a 3L block with a 3L offset grind crank using 4G63 Rods (Mitsubishi) / rod bearings. The pin diameter was custom spec'd @ .866 specifically for a Mitsu 4G63 rod making these "plug and play" with the rods. The engine specs for the pistons were as follows: Deck Height 9.03 (stock 9.05) Bore 4.125 Stroke 3.622 (92mm) = (deck clearance .043 @ 8.01:1 compression) - (you could take this to 93mm with deck clearance .024 @ 8.35:1) Rod Length 5.9 Chamber Volume (61cc - this varies but what my actual 2.7 8V head measured) Gasket thickness 0.40 (again this varies and can be raised/lowered depending on what you desire for compression / etc.) Piston dome -34cc Pin Height 1.276 You will need to buy JE 4.125 rings and .866 pins to install (*not included*), let me know if you have any questions, thanks!
