Infinit Performance Mclaren Engine Rebuild

Infinit Performance Mclaren engine rebuild Stage 1 Longblock only (must provide core) 1100 whp, Infinit Performance Mclaren engine rebuild stage 2 Longblock only (must provide core) 1800 whp 

 

The McLaren M840T is a 4.0 liter, Twin Turbo, flat plane V8 engine that powers the 720s, Senna, GT,  Speedtail exotic sports cars.  Released in 2017, this is the latest upgrade to the 3.8 liter M380T found in older models like the 650s.  Even further back, the engine carries residual DNA of a LeMans Nissan Engine and turbos from a Mitsubishi EVO.

After it’s launch, the 720s quickly became popular amongst tuners, sharing drag strips with the likes of Nissan GT-R’s and Audi R8s, yet claiming a lane for itself with an identifiable exhaust note.  Our friends at MSL Performance were the first to start testing the limits and set the benchmark with the world’s first McLaren 720s to break the 200mph barrier with a record pass of 14.76 seconds @ 202.15 mph in the standing half mile and 22.93 seconds @ 227.99 mph in the standing 1 mile.

As others enthusiasts began to modify and upgrade their McLarens, Infinit Performance began getting calls for repairs and upgrades across the globe.  McLaren did not offer replacement parts at the time and customers requested increased loads of over 1500 hp to be placed on the engine.  Post mortems revealed the engines were suffering from excessive oil consumption, early failure and bent connecting rods – and a need for replacement McLaren Parts.

The Infinit Performance McLaren Engine Development Program utilizes our over 5 years of experience in producing some of the worlds finest racing engines and road engines.  We have produced proprietary Pistons, Connecting Rods and Crankshaft, as well as improved Cylinder Liners, Head Gaskets, Fasteners, and all other associated parts needed to build and manage added power.

Infinit Performance has developed a Longblock engine program for Mclarens, we only provide sealed units for the client.  No Shortblocks, we receive your engine and completely recondition it to the modifications of your choice Stage 1 or 2.   We can also offer to upgrade your M838T 3.8L engine to M840T 4.0L spec.   A good core must be provided.   You will receive complete and sealed engine with all timing components installed, and valve covers and engine covers attached.

Racer Reviews: Hear From Our Satisfied Speedsters

Awesome Team! Received remote advise on my car troubles that helped sort out a painful longstanding issue. Wish they were local!

Dan Burezo

Best in the game!

Took my RS3 to stage 2 including the engine safety’s! Had it done remotely so no need to travel from down south. Aoon and Sean were a pleasure to deal with and explained everything clearly. Really straight forward installation, 0 issues. 100% would recommend to anyone. Will be back next year for stage 3!

Absolutely Top-Notch!

Went for a stage 1 upgrade on my RS3, all done remotely—no travel needed. Team made it easy and hassle-free. Installation was smooth, zero issues. Highly recommend Infinit Performance.

Alex
★★★★★

Booked a stage 1 + tune on my engine for the RSQ3. The service was better than I expected. The infinit team were super welcoming and explained most changes they were making and the best upgrades for the car. It was well worth the drive and gave me confidence in their work.

Matthew Stanley
★★★★★

Had major engine issues, basically had to rebuild from scratch. Sent the car to Infinit and the guys were brilliant, had a quick turnaround and although a few minor teething issues, which were covered under warranty, the car is an absolute demon! These guys know what they are doing when it comes to RS3 engines. Highly recommend their services.
