CI Low Compression (TURBO) Performance Long Block Eclipse Talon 420a

This is a complete long block engine that's specifically built for those who want to maximize HP while running boost. Based on years of building engines we have decided that this is the ultimate forced induction engine setup for your 420a! Capable of big boost, nitrous and high rpm, all while maintaining daily drivability. Here's a breakdown of the parts we use in this setup. Now of course you have a few options to select from, but we have taken all of the hard work out of it for you! Your choice of low compression pistons (Wiseco or JE) Eagle connecting rods , King Bearings,  OEM Crankshaft,  Melling High Volume Oil Pump,  Airtex Water Pump,  new timing tensioner,  Gates Performance Timing Belt, new idler bearings.  Fidanza Cam Gears,  Cometic Head Gasket,   ARP Head Studs  and ARP Main Studs.


Now combine it with our Staged Cylinder Head which includes: Stage 2 Cylinder Head Porting , PT Cruiser Style Lifters,  PT Cruiser Style Rockers,  PEP +1mm Oversized Stainless Steel Valves,  Brian Crower Valve Springs & Retainers.  Brian Crower Stage 2 Forced Induction camshafts, and ARP Cam Tower Studs. Wrap that up with some Felpro Gaskets and you have one mean long block! Capable of BIG power numbers, the only thing that really holds you back is the factory crank rating, which is at 500hp. We have customers that have been running more then 500hp no problem, but we must make you aware of the limitation. Add this engine with a Megasquirt ECU, HUGE turbo and a few good friends to help install the parts and you will have one MONSTER 420a tearing up the streets! Most builds will be at least a 6 week wait time before shipping. Time may vary...call for more details! All engines are bored, hot tanked, block and head surfaces are decked and are torqued to spec. No core charge!
