This is the NEW Tial MVS 38mm with a 38mm Vband Flange Inlet and a Vband Flange Outlet. The kit comes with both the inlet flange and outlet flange AND both clamps. It also includes all air fittings, block off fittings, banjo bolts and everything else required to install.

HKS vs GT naming conventions

The HKS and GT turbos are similar , the HKS turbos are actually manufactured by Garrett. They utilize similar parts except for the compressor cover and turbine housings. Below are your cross reference compiled by Tong Turbo.

GT30 & GT35 T4 Divided 1.06 A/R .ar housing

There are lot of turbocharging freaks looking out for a T4 Divided housing for the GT30 and GT35. There is an anwsers, previously ATP brought out a housing sized 1.06 .ar , but reviews were bad and the design of the divided flange was not the conventional T4 flange. Cracks was also one of the issues of this housing. ATP has redesigned the turbine housing and have launched out their new product.

GT Ballbearing vs EFR Ballbearing catridge

A review comparing EFR and GT ballbearing surfaced up the internet sometime ago showing the picture below claiming the EFR to have a bigger ballbearing cage. The truth is both the GT and the EFR has bigger cages but they start at a diffrent turbocharger frame. The border catridge is actually a GTX3582 which oftenly is compared to a EFR8374 and also the GTX3076 with the EFR7670.

The GT/GTX series is divided to 3 frames while the EFR series is divided to only 2 frames.
GT25/28 Frame1, GT30/35 Frame2 , GT37,40,42 Frame3.
While in the EFR series , all EFR up to EFR6758 shares one frame while anything above it shares a bigger catridge. In comparison the EFR7670 sits in a bigger frame while GTX3076 sits in its seconds frame thus EFR having a bigger cage but also a beefier shaft which also means heavier. No doubt the GT series are proven till at high boost capabilities till today despite it counterparts differences. GT30/35 based turbos are one of the most used turbocharger in the Motorsport industry where some with billet wheels surpass the 800hp range.

Garrett GTX vs GT 3076

Below are some results of GT3076 vs GTX3076, how technology of the new blade by Garrett make difference in power and response. The new GTX is a all new billet wheel which was carved to perfection on a C&C machine.

Hi all... i have conducted a TRUE comparison between the two turbos thanks to Sonic Performance and Garage 7. By true comparison i mean the only thing changed was the turbo. nothing else was touched. The result was suprising and disappointing both at the same time. We found that the GTX version DID spool quicker and hence started making torque and power earlier in the midrange. i now have FULL boost around the 3500 rpm mark which for a turbo like that is impressive. Its highly streetable! 
The downside is that for the same boost level peak power is changed by .1 of a kw! its pretty much lineball! the two turbos match each other on the graph pretty much spot on.
runs were done with air temp probe and same correction mode and dyno that STatus uses for real world comparison. 
Solid pink line is GTX, thin red line is GT. 

See how much faster the GTX builds boost

VR4 AMG Intake Manifold 4G63

Comparison of the super Rare VR4 AMG tuned engine intake manifold vs the cyclone intake and the 1G / 4g67 intake manifold. The AMG is superior in size and flow. The AMG engine was built natural aspirated but it whopped nearly 200hp on a 2Liter 4G63.

Evo vs Vr4 head , DSM 1g vs 2g head

There are much confusion between the 1G vs 2G DSM head. The 1G head is similar to the VR4 Head while the 2G head is similar to the Evo 1,2,3. There is another head stamped 1.8L which is similar to the VR4 but instead of 47cc , it is a 43cc combustion chamber.
