For the last 30 years we have been building high performance engines for a range of applications, races and championships.

Since the release of the Nissan R35 GT-R have built hundreds of performance engines from rebuilt OEM-spec to full hardcore drag-spec using where we select only the strongest and most exotic components. We've also had countless custom fabricated items to support our powerful builds including the use of Billet components.

Our 'Level 1' performance engine build focussed on extreme duty conrods to boost internal strength of the short block considerably to allowing for maximum engine power output to go beyond 750 HP (with 750 FT/LB torque). You will of course need supporting engine modifications to create this level of power (Larger turbochargers / Bigger Injectors / Fuel Pumps etc) but ultimately you can rest in the knowledge that after this level of engine your GT-R's engine is considerably stronger and capable of supporting a large increase in power. This engine spec is capable of exceeding 850HP, if you plan to run more power then a complete pistons & rod build is the way forward.

Key Components:

• SVM - Forged Rods (1400HP capable).
• ARP Main Stud Bolt Kit.
• Replacement Nissan Gaskets (Heads & Generall).
• Replacement Nissan Piston Rings.
• Replacement Nissan Bearing Set.
• New Nissan Oil Filter.
• New Nissan Timing Chain & Modified Water Pump.
• New 'Custom-made' NGK Spark Plugs.
• Motul Competition Oil (5w40)

Tasks Involved:

• Engine Bores are Honed.
• Cleaning of the Oil Pump Assembly.
• Dynamic Balancing of Pistons, Rods, Crank, Flywheel & Pulley.
• SVM Complete Engine Cleanse
• Joe Gibbs running in Oil useds to 'bed' engine in.
• Complete running in process of 250 - 300 miles.

Next up is to go a step further with our 'Level 2' performance engine build which not only replaces the rods, but also replaces pistons (with some capable of handing big power). This level of engine build we use successfully to handle our SVM builds of 'up to' 1300 HP (with 1000 FT/LB torque) maximum. Other supporting mods are of course required to produce such power levels but an SVM block with these components is exceptionally strong.

Key Components:

• SVM - Forged Rods (1400HP capable).
• SVM - Forged Pistons (1400HP capable).
• SVM - Sport Camshafts (Increase Lift & Duration - Fast Road).
• SVM - Custom Spec Valve Springs (for correct valve pressure).
• SVM - Ported & Polished Cylinder Heads.
• SVM - Titanium Retainers, Combustion Chamber with improved squish.
• SVM - Trojan Valve Guides with Blue Printed Oil Pump + Pressure Check.
• ARP Main Stud Bolt Kit.
• Replacement Nissan Gaskets (Head & General).
• Replacement Nissan Piston Rings.
• Replacement Nissan Bearing Set
• New Nissan Oil Filter.
• New Nissan Timing Chain & Modified Water Pump.
• New 'Custom-made' NGK Spark Plugs.
• Motul Competition Oil (5w40)

Tasks Involved:

• Engine Bores are Honed.
• Cleaning of the Oil Pump Assembly.
• Dynamic Balancing of Pistons, Rods, Crank, Flywheel & Pulley.
• SVM Complete Engine Cleanse.
• Joe Gibbs running in Oil useds to 'bed' engine in.
• Complete running in process of 250 - 300 miles.

This 'Level 3' performance engine build is for those who want to truly start pushing the boundaries and build a motor with capabilities to withstand power levels 'up to' 1500HP... It is 'crucial' that when you are developing such high engine horsepower you must construct the engine to the tightest tolerances using on the absolute best components.

We have always strived to create the 'most powerful' Nissan R35 GT-R's and are accolades back up our builds, We use this experience, coupled with some SVM magic to develop the 'Fastest' GT-R's in the country (i.e. F-Man's GT-R being the UK Fastest R35 GT-R over a Quarter Mile - still standing in 2016). If your budget stretches to develop a GT-R to 'roll with the big boys' in GT-R tuning then look no further. Although this extreme engine spec can develop huge horsepower our SVM versions is also very reliable, one of our customers has covered a faultless 12,000 miles at 1400HP using this specification build as a testament to its strength and quality (providing frequent SVM servicing is performed of course).

Key Components:

• SVM - Extreme Duty Forged Rods (1500HP tested).
• SVM - Extreme Duty Forged Pistons (1500HP tested).
• SVM - Extreme Duty Crank 3.8L (or) 4.1L Stroker Spec (1500HP tested).
• Replacement 'Custom spec' Head Gasket set (2100HP tested).
• ARP Main Stud Bolt Kit.
• Replacement General Gaskets.
• Replacement Nissan Piston Rings.
• New 'HKS' Oil Filter.
• New Nissan Timing Chain & Modified Water Pump.
• New 'Custom-made' NGK Spark Plugs.
• Motul Competition Oil (5w40 - will require regular changes).

If this short block is spec'd with our own High-Revving Big Valve Heads it makes for a truly phenomenal engine.

Tasks Involved:

• Engine Bores are Honed.
• Cleaning of the Oil Pump Assembly.
• Dynamic Balancing of Pistons, Rods, Crank, Flywheel and Pulley (balanced to to within just 0.2g +/-) oem is 2g.
• SVM Complete Engine Cleanse.
• Joe Gibbs running in oil used to 'bed' in engine.
• Complete running in process of 250 - 300 miles.

Our 'Level 4' is the pinnacle of GT-R performance. We are well-known pioneers for building drag spec vehicles here in the UK and coupled with our years of experience as well as our unique links into the world of American and Middle Eastern drag racing teams is the reason you'll find a number of SVM built & tuned builds at the top of the UK leaderboards for R35 GT-R's.

Through development, and the need for stronger items for power levels approaching, and over 2000HP we use billet components. We have heard stories of blocks literally splitting in half when exceeding 1500HP and it is not a risk we'd ever want to take. We may push the boundaries, but we do it with precision, skill and with safety in mind.

If you are looking for a company to build you the most powerful R35 GT-R engine in the UK for your R35 GT-R, give us a to call.
