Genuine is best - FAKE wheels fail safety test

Fake wheel failing a pothole test. 
A set of fake wheels on sale in Australia have been shown to dangerously disintegrate at just 50km/h in testing. The test was carried out by the Australian automotive industry and saw Mercedes-Benz Australia Pacific and GM Holden team up to demonstrate to consumers the serious safety risks that can be associated with fake parts.

Using imitation Mercedes-Benz wheels purchased online from an Australian-based seller, engineers set out to compare them to genuine wheels in an impact test.

The test was a pothole test, which saw fake wheels break apart at just 50km/h. This occurred in separate tests, one in which the point of impact was close to a spoke and one where the point of impact was midway between the spokes. Under the same tests, the genuine wheels sustained no visible damage

TRP RACING RB30 POWERED 300ZX 6.72 @ 205 MPH

Well, a tube frame, big tire car that resembles a 300ZX.  Makes some power to do 205 mph. Probably a 3.2 liter. Big single Garrett turbo on it.

How Do I Build a 500 Horsepower Skyline GT-R ? 600 Horsepower ? 700 Horsepower ? 800 Horsepower


R32 GT-R on the dyno. The emissions dyno, for California compliance. 
How do I build a 500, 600,700,800 horsepower Skyline GT-R?  Be it R32, R33, or R34, the RB26 in the Nissan Skyline GT-R can more or less be called the same from 1989 to 2002. There are some minor differences, a few different blocks, some different turbos and exhaust manifolds, but for 95% of the RB26 out there this is all the same.

#1 The turbo makes the power
#2 The supporting modifications make it work and survive


Turbochargers


Do those two statements make sense to you? The engine itself is just a big air pump for the turbocharger.  We have a hard time changing the engine characteristics without getting into the RB26 internals.  The more air the engine can push at the exhaust wheel, the more air the compressor side can ingest.


The bigger the inlet, the bigger the compressor wheel, the more air it will flow at a given RPM. The more it weighs, the harder it is to get it up to a certain RPM. Turbo sizing is a bit of an art and a science. You have to read into some of the compromise to achieve certain levels of performance.  If you aren't sure, then you go off past data. If you want to experiment, first check and see if anyone else has done it.  The current world in turbos for GT-R's, the popular route is a single turbo, from the OEM twins.  While we personally prefer the OEM look of under manifold twins, that look isn't for everyone.

2002 Nissan Skyline GT-R Vspec II Nur vs 2017 Ford Focus RS

This has the internet all ablaze today. 15 years newer. We think the HP might be a little high on the R34, the weight low.  The 1/4 mile time low, they will do low 13's. Top Speed is about right, they are a aerodynamic brick stock.

8000 rpm for the RB26 vs 6600 for the Ecoboost 4 cylinder. The inline 6 will always be smoother and sound better.
