WHAT WE DO

Full-service engine shop.
Every part machined in-house.

01

Engine Assembly

Complete builds from bottom to top. LS, LSX, LTX, small block Ford, Windsor, and everything in between. Race, street, marine.

02

Precision Machining

Line boring, deck surfacing, valve jobs, custom crank grinding. Everything needed to make parts hold power.

03

Engine & Chassis Dyno

Two dynamometers — one for engine pulls, one for chassis testing. Every build validated before it leaves the shop.

04

LS / Swap Engineering

OEM-quality LS swaps into older platforms. Motown LS blocks, swap packages, and full conversion support.

We don't just build engines. We build machines that run harder than anything else on the street.

Custom Performance Racing Engines was founded in Gardena, CA with one goal: push the envelope on what a street engine can do. Every machine we build starts with precision machining and ends with a dyno pull that proves it. If it doesn't make the numbers, it doesn't leave the shop.

From 682 HP naturally aspirated Motown II builds to 986 HP hydraulic roller LSX engines — we prove it on the dyno, every time.

THE MISSION

To push the envelope on performance engines and bring the latest innovation in high-performance engineering to every customer who walks through the door.

THE OS

Behind every great engine shop is a messy system — sticky notes, missing paperwork, unclear job status. ThrustOS gives CPR Engines a real command center: job tracking, customer management, quote building, and dyno result publishing. Built to run the shop, not just document it.
