Chris Wilson Posted October 19, 2017 Share Posted October 19, 2017 The most pertinent question to ask is whether any of these are cast from high nickel content cast iron like the stock manifolds. HKS do some cast manifolds, or did, for various jap engines, but they cut costs / maximised profit by using normal grey cast iron and they can and do crack and the flanges warp. Garret make their high performance turbo turbine housing from high nickel content cast iron to stop internal flaking (the cause of turbine wheel erosion or "pecking", and flange warping, they use a proprietary name for it "Ni-Resist" Some interesting tech papers, the manifold material should be similar to high end turbine housing for high performance / race gasoline engine turbochargers. http://www.ask-chemicals.com/foundry-products/applications/turbocharger-casting.html https://energy.gov/sites/prod/files/2014/03/f10/pm038_maziasz_2012_o.pdf https://www.turbobygarrett.com/turbobygarrett/sites/default/files/Garrett_White_Paper_02_Burst__Containment.pdf Quote Link to comment Share on other sites More sharing options...
Bladerider Posted October 20, 2017 Share Posted October 20, 2017 FSR Motorsport in the US do a really nice cast manifold if you wanted something slightly different - http://fsrmotorsports.com/component/virtuemart/?page=shop.product_details&flypage=flypage.tpl&product_id=129&category_id=22&Itemid=87 That is actually a SPA cast manifold that FSR modify and then charge a fortune for !!! As you can see - this design has a slightly larger bore and "guides" the exhaust gases slightly with its ported shape - this also benefits from further porting and machining if you can be bothered. They are made from High Nickel cast iron and have been making turbo parts for years. J. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 20, 2017 Share Posted October 20, 2017 Can you point me to the material specs please? i would like to buy a high nickel content cast iron, or cast "steel" log type manifold for a customer, thanks. Quote Link to comment Share on other sites More sharing options...
