WHAT IS THE DIFFERENCE BETWEEN THE FINISHES ON MY SINCO MANIFOLD

Pictures below are the x3 main finishes that we offer on our turbo manifolds.

Steamtube - Matte Black = This is our entry level finish, the manifold is beadblasted and VHT painted matte black. This is not a permanent coating and over time will start to rust, on the Evo manifolds where the manifold is directly under the bonnet vents they will rust a lot quicker because water leaks directly onto the manifold.

Stainless Edition = This finish is made from stainless steel 2.7mm thick (sch. 10) and is fully back purged and the welds have full penetration. We recommend this type of steel if race fuels are being used - E85 and Avgas etc. The manifold starts its life bead blasted and the flanges are painted matt black (they are mild steel), this is to keep the cost down and help prevent flange distortion (Stainless Edition finish before heat). Once the manifold goes through different heat cycles it will change colour starting off a blueish colour then moves to a bronze look like the picture below over time it will go more of a brown/black colour depending how hot it gets from different driving styles - i.e street or track.

Burn Edition = This finish is still made from 2.7mm thick (sch. 10 ) stainless steel but instead of the bead blasted matte finish like the stainless edition, the welds are left in a raw state. This is achieved by large gas coverage and high argon pressure when welding along with around 2-3 hours extra labour. This is the most expensive manifold available in our range and can be added to any manifold we fabricate.

WHERE DID THE NAME SINCO COME FROM?

Sinco comes from our family name, "Sinclair", and the word "Company".

WHAT WARRANTY DOES MY SINCO MANIFOLD COME WITH?

All SINCO turbo manifolds come with a 5 year no crack warranty. We will upgrade to a 10 year warranty if we fit the manifold, setup the downpipe and bracing to the gearbox at our workshop.

HOW DOES THE NO CRACK WARRANTY WORK?

The warranty term starts from the invoice date. If you choose to claim the warranty you will need to provide the invoice from when the manifold was purchased.

WILL THE WARRANTY TRANSFER OWNERS WITH THE VEHICLE?

Yes, the warranty will transfer but the invoice must be provided if a claim is made.

SHOULD I HEATWRAP MY MANIFOLD?

We recommend not to use heat wrap on manifold as this overheats the steel and causes flange warping from excess heat. If our manifolds are heat wrapped this will void all warranties

CAN I RE-USE MY FACTORY EXHAUST MANIFOLD NUTS?

These can be re-used but we recommend using a locking nut to fasten your manifold. As the heat and vibration will cause a standard nut to work loose over time. Also factory exhaust manifold nuts sometimes use a flange section built into the nut. This will clash with the weld/runner on the main flange. SINCO manifolds are designed to use a 14mm head nut on M1O threads and a 12mm head nut on M8 threads.

WHAT THREAD PITCH IS MY TURBO MANIFOLD FLANGE?

M10 x 1.25

CAN I RE-USE MY FACTORY EXHAUST MANIFOLD STUDS?

We recommend replacing your factory studs when up-grading your turbo manifold. The studs generally are years old and become vulnerable to stripping the threads and snapping off.

CAN I USE EXHAUST CEMENT TO SEAL MY MANIFOLD?

Under NO circumstances ever use exhaust cement on your exhaust manifold or your turbo flanges. This sets rock hard and if any were to break off and go through your turbo it will cause major damage

WILL MY TWIN SCROLL TURBO WORK WITH MY SINGLE SCROLL MANIFOLD?

Yes and NO. Your turbo if T3 and T3 twin or T4 and T4 twin share the same stud pattern so will bolt on, but there is no benefit or gains from the twin scroll unless a correctly made twin scroll manifold is used. You will see 500-700rpm better spool from a correctly made twin scroll manifold over single scroll with the same A/R.

-You will not get any performance gains or quicker spool time if a single entry turbo is used with a twin scroll manifold

-You will not get any performance gains or quicker spool time if a twin scroll turbo is used with a single scroll manifold

DO I NEED TO MATCH PORT MY TURBINE HOUSING WITH MY HOLSET HRC SERIES TURBO WHEN RUNNING T3 TWIN SCROLL?

Yes you will need to match port your turbine housing to get the best flow and power from your manifold/turbo combo.Our T3 twin scroll flanges are cut to suit the Garrett turbine housings which are the most common pattern, The Holset HRC series turbos have a smaller inlet pattern size so need to be match ported to suit.

SHOULD I BRACE MY DOWNPIPE TO HELP SUPPORT THE TURBO?

Yes, we recommend to use bracing to help with the weight of the turbo under high heat and vibration conditions.

ARE MY TIAL MVS-38 AND TURBOSMART 40MM COMPGATE VBANDS INLET WELD FLANGES THE SAME?

Yes both brands share the same inlet weld flanges.

ARE MY TIAL MVR-44 AND TURBOSMART 45MM HYPERGATE VBANDS INLET WELD FLANGES THE SAME?

Yes both brands share the same inlet weld flange, also the gfb44 an the precision 46mm vband are all the same. The inlet hole size is slightly different for each brand but the section where the wastegate seat fits and the OD of the vband is the same size.
