Forged Performance Announce the VR38 FP1 Short Block for Nissan GT-R
It keeps getting more interesting in the built VR38 world with another newly announced complete, built, short block hitting the market in a big way. This time hailing from much closer to home for many of you, Marietta GA, comes the Forged Performance VR38 FP1 short block for Nissan GT-R.
The Forged Performance FP1 Shortblock strengthens the GT-R engine for maximum reliable power! We start with a BRAND NEW VR38 block casting, and all new OEM parts. The OEM rods and pistons are replaced with Pauter forged rods, and our own spec Arias Extreme Duty pistons. The block is precision CNC machined to accept a new cast iron cylinder liner. The cast iron liner allows for the long term reliability and exceptional strength when running forged pistons at very high power levels. The is the same proven strategy used in numerous 1500whp+ builds in the exotic car world. After the liners are fitted the cylinder walls are bored and honed to .0001 tolerance and the block is decked flat. The liners are purposely left .001 above the deck for headgasket seating and block expansion purposes. This block is engineered to handle 1000whp+ easily.

Carillo Rods and Pistons for Nissan GT-R
Carillo manufacture serious rods and have joined with CP to develop rod and piston sets suitable for the Nissan GT-R. The CP pistons are a forged upgrade over the standard VR38’s cast items. The forged construction allows improved strength at a potential lower weight.
The Carillo connecting rods (conrods) are also forged in a H-beam configuration. The OE rods are forged too but are I-beam design. The H-beam rods are usually lighter than their I-beam counterparts while maintaining similar strength characteristics.
That’s pretty much all the info we have for now, if you’re interested in knowing more hit up Injected Performance at the link below.
