Battle of the Mega Godzillas Heats Up: SPE1000 and Switzer R1K Dynos

September 17, 2010 Comments off

Two huge builds are reaching tipping points in the GT-R world this week with big news from two prominent tuners that the 1000awhp barrier has been effectively reached. In one case it’s even been poked with a sharp stick.

First up from Switzer was the announcement that their R1K prototype build has reeled off a 1005awhp dyno pull at 32 – 34.5 psi of boost running VP C16 fuel. To get this level of power the R1K package will feature custom manifolds, and a pair of big Garret watercooled turbochargers fitted with external wastegates. Switzer are also quick to point out that this tune is not right on the ragged edge. Conservative timing and boost settings are deliberately chosen for durability.

Hot on the heels of the R1K update, SP Engineering announced that their SPE1000 build has bumped its head against the limit of it’s ID 1000cc injectors at 997awhp (886 lb/ft of torque). They ran 30psi of boost for the pull on C16 fuel. ID 2000cc injectors are due to be fitted shortly to sort that and back on the dyno to make it an official round 1000awhp … or more…

So yes, it’s huge news and it won’t stop coming any time soon with AMS set to have their own 1000whp Alpha GT-R demons on the dyno in the not too distant future.

Right now it’s a little too close to call who will win down at the track and that really is where the where the winner will be decided. Can’t wait to see it!

SP Engineering Stage 1 SPE750 Turbo Upgrade Package

November 16, 2009 Comments off


SP Engineering have announced their own 750hp+ stage one performance upgrade for the Nissan GT-R based on their SPE750 upgraded turbochargers. The turbos, based on standard IHI ones, are honed out and have their internals replaced with ball bearing type cartridges. There’s an increase in the compressor and exhaust wheel size but this is probably countered by the improved ball bearing design to maintain response.

The package also includes JET coating on the integrated exhaust manifolds. This will help keeping heat out of the engine bay and in the exhaust. This keeps exhaust gas temps higher and improves gas flow. Obviously it also takes heat out of the engine bay as well which benefits the cooling system overall.

The full SPE750 package will consist of supporting modifications to help owners get the most from the turbos including 800cc injectors, upgraded fuel pressure regulator with lines, upgraded dual 255 litre/hour fuel pumps.

A HKS GT570 kit is included as well to cover the exhaust, intake, boost control, ignition and wastegate control side of things. To control all this, owners will be supplied with a Cobb AccessPORT map specifically for the SPE750 setup.

MSRP for the full setup is set at $18,500 installed.

For those wanting to push the GT-R even further, SP Engineering have a GReddy TD06-20G twin turbo based SPE900 kit as well but pricing is yet to come for that.
