Our first Trust / Greddy turbo kit just arrived to our offices yesterday (this one is spoken for but we have more on order). We had an opportunity to get some good photographs of the kit and wanted to share with everyone!
There is a lot of buzz about this turbo kit lately and I wanted to take some time to explain a bit more about it and to address some of the confusion that I know many GT-R owners are having with regards to the kit. There are a couple of key points I wanted to address, although I’ll try to keep this short since I can talk on this topic for far longer than I should on a blog.
1. It is not a complete turbo kit, it is more along the lines of a “set-up turbo kit” as we’ve seen them called in Japan in the past. This is a common misconception that should be addressed. Unlike many of the other turbo kits that we offer (we sell every turbo kit on the market), thisÂ does not have included solutions for intercooler, fuel, or computer/tuning, etc. Fortunately we and our GT-R master tuner John Shafer have the turbo tuning experience to provide you with complete solutions to reach your goals. Price-wise however, please understand that the real costs of using this kit are significantly higher than this set-up package. Greddy specifies that this kit can not be used at all without also purchasing an intake piping kit (by which they mean intercooler hardpipe kit), and really that’s just the tip of the iceberg.
The true cost of this turbo kit is more along the lines of:
This kit +
Hard Pipe Set (approx $1800)
Haltech ECU ($3199)
Intercooler (approx $3700)
Tuning (we offer tuning services at various price points)
Total – $19,000+
2. This turbo kit makes very strong power, however due to its turbine size and manifold configuration the response is not going to be exactly as quick as stock as well as some other turbo upgrade solutions. We suggest consulting with us so that we can determine the best solution for your needs, whether it is this kit or any other kit on the market. Because we offer every kit on the market we’ll give you unbiased consultation to help you make the best choice.
3. We encourage people to not use dyno numbers as comparisons alone. Dynos have a high degree of variability when comparing with one dyno to another. The important factor in evaluating peak horsepower of this kit is the gain on the same dyno when compared to stock. That specific gain is 230hp according to Greddy (604.4ps before vs 834.3ps after). Having seen GT-Rs that put out 390 to the wheels stock on other dynos (compare that to Greddy’s stock readout of 604hp in their literature), simply looking at 834ps as a peak number can be a bit misleading if not put into context.
4. Due to the nature of the aftermarket (non OEM design) manifolds and turbines, this turbo kit does have higher peak horsepower potential than all other OEM type turbo kit upgrades out there. Typically the OEM design turbo upgrade kits can flow to 800-900hp however we expect the design of the Greddy turbo kit to be able to support higher peak horsepower on cars with built engines and fuel/ecu tuning that can support it.
This turbo kit includes:
two TD06SH-20G 8cm2 turbos
two stainless 45mm exhaust manifolds with 42.7mm wastegates (type R spec)
two stainless steel downpipes which expand from 60mm to 70mm
two compression tubes in aluminum 60mm
intake pipes out of aluminum
We’ll continue to order up more of these turbos as well as continue the variety of kits so that we can provide the best unique solution for our clients. With the GT-R it is certainly not one solution is best for all, as with most tuning parts there are pros and cons to each option and the only way to do it right is to make an educated and well consulted decision. That’s why we’re here to help.
