JBS Garrett GT Equal Length Upgrade Stage 1-3

The JBS Garrett GT Equal Length Kit is there cutting-edge turbo upgrade for your 1.8 20 VT. At JBS have worked long and hard to bring you the finest 1.8T upgrade available. All there kits are made with the best materials and engineering available, from the exhaust manifold to the hose clamps. The JBS Garrett GT Equal Length Kit is offered in 3 stages from 350-600 Bhp

JBS's Garrett GT Equal Length Kit consists of the following components:

• JBS Tubular Exhaust Manifold
• Garrett GT Turbocharger
• JBS Downpipe
• JBS De-CAT/High Flow Catalytic Converter
• JBS Custom boost hoses
• All Associate Plumbing and Hardware

The most important part of the Garrett GT Equal Length Kit is the exhaust manifold. JBS has spent enormous time and resources developing the turbo manifold. The exhaust manifold has been designed in the best CAD packages available, for 3-D modelling and CFD analysis. By performing a computational fluid dynamics analysis, we were able to study exhaust flow, pressure drops, and fluid flow through the exhaust manifold. Multiple computer simulations were done to prove the design before they even had a physical manifold in our hand.

Once the manifold was fully passed on the computer they had the exhaust manifold CAD file transferred to a SLS rapid prototyping machine. A nylon resin exhaust manifold was cast from the prototyping machine. With this plastic manifold we were able to mock everything up in the test vehicle before proceeding to the next process.

Benefits of the equal length manifold are:

• Better Pulse Distribution
• Quicker Spool Times
• Sustained Top End Performance
• EGT's Dramatically Cut

Design features include:

• Fabricated from 321 and 409 Grade stainless steal
• Inside diameter 34mm for better overall power band
• Precision TIG welded for maximum strength and liveability
• Cutting and separating the head flange insure unbreakable construction
• The laser cut head flange are machined ensures sealed surface. CNC cut collector to ensure accuracy
• JBS equal length manifold allows use of a 3.0" Down-pipe for maximum performance.
• there collector is welded inside and out which further prevents cracks.

The same designs process is carried over into all there turbo kit components. The turbo out, TIP and boost pipes have all been design, flow tested and prototype using CAD, to give the best possible performance. Our Boost pipes are available in silicone or stainless steel.

For the JBS Garrett GT Equal length kits stages 1-3 custom built Garrett GT turbos are used. The turbos are selected for best power output and compatibility with the other components of the turbo kit.
