Most Powerful GT-R in the World Gets More Power

ADVERTISEMENTS

The Heat Treatments R32 Nissan Skyline GT-R went back onto the dyno just a few days ago, and found even more power.  The last dyno numbers that were shown on the Heat Treatments site showed 1667 hp. Now with a bigger exhaust, and other modifications the car put down an additional  115 hp to the wheels, or it should be around 1782 hp.

They will be trying the new setup, with the increased power at the Jamboree in Queensland Australia on 21-22 August 2010.

8 Second R32 GT-R From the UK

ADVERTISEMENTS

This R32 is pretty impressive for what modifications it has. It turned a number of 8 second passes. On slicks, and good fuel. The engine is a 2.6 with a standard R33 crankshaft, JUN rods, HKS pistons, Tomei oil pump , HKS 272 cams , HKS T51 Kai turbo , Veilside plenum. Its running an OS 88 sequential transmission, and a little squirt of nitrous to get it hustling.

The following is some information on the stock and aftermarket turbos available for the Nissan Skyline GT-R , and Nissan GT-R. R32, R33, R34, R35 as they are often referred, being the chassis codes.
 

 

 

 

 

 

 

 

R32, R33, R34

Above about 1.1 bar the stock RB26 turbos have a tendency to break the exhaust wheel off. People have gone low 12's, high 11's on the stock turbos, but not for long. Stock peak boost R32 is about 0.8 , R33 0.9, R34 1.0.

 

 

 

 

 

 

 

The exhaust manifold on the left side of the picture is a stock R32,R33, R34 piece. On the right is a modified N1 exhaust manifold from a Nismo built Super Taikyu car. You can see bracing between the manifold flanges, and the larger hole for the turbo “foot”.

 

 R35 GT-R

Uses an IHI turbo, with an integrated exhaust manifold.
