Gemini BIG BLOCK
With the Stock D1 on 14psi pushing the Car into the low 13's with 180-200rwhp the hunger for more didnt take long. After much research it was decided to use a 4ZE1 2.6L
​
The block was checked and put through every machine process under the sun including Torque plate plateau honing for the absolute best ring seal.
​
With advice from a pro engine builder some Custom JE forged pistons were designed utilizing full floating pins, reduced weight, anti-scuff skirt coatings, thin perfomance rings and a thick crown for maximum power handling and ceramic coating for thermal protection. These were attached to a set of new forged SPOOL H-beam connecting rods with ARP2000 rod bolts.
​
ACL Race bearings, new core plugs, seals, ARP head studs, MLS head gasket, hi volume water pump, new water pump and timing gear
​
The head was hardness tested, bead blasted, professionally ported, oversize stainless steel valves and springs fitted. Combustion chambers, exhaust valves and exhaust ports were ceramic coated.
​
The expectation was 350-400rwhp using a Garret 30/76 spooling to 20psi but while also keeping in mind enough is never enough and it would handle a larger turbo and more boost if / when the need arose.
​
Unfortunately life got in the way and the engine has to date never left the engine stand :(
