Revshift turbo manifolds are temporarily
out of stock. We used to make the manifolds to order which occasionally
created an unsatisfactory wait time. We are now working toward keeping
the manifolds in stock so that we can ship them out as soon as you place
your order. Expect to see them back in stock soon. We apologize for any
inconvenience this may cause you.
This is a twin scroll top mount turbo manifold designed to fit the BMW 3-series E30 1983-1991 / M20 engine.
Revshift turbo manifolds are 100% hand fabricated from high quality 304
stainless steel. They are fully TIG welded by a professional welder
using a back-purging technique and multi-pass welds for maximum strength
and durability. The runners are schedule 10 304 stainless steel and the
flanges are made from thick 304 stainless steel.
All of our manifolds are assembled on an oem cylinder head to ensure
perfect fitment and stud clearance. The turbo flange is tapped to accept
10mm bolts for easy turbo installation and removal. Each flange is
milled on a high precision milling machine to guarantee a leak free
Revshift twin scroll manifolds are designed to spool the turbo as
quickly as possible. The runners are arranged to be as close to equal
length as possible without causing clearance issues. They are ported and
polished for maximum flow and velocity.
