Is your H series ready for 800+ WHP? The Boostwerks Top Mount will easily support the highest power levels and keep screaming for more! It will fit up to a Garrett GT42R or a Borg Warner S372 in a prelude chassis with little modifications. Hood modifications are required in a 92+ civic chassis.

I highly recommend going with the twin scroll and dual wastegate option with this manifold if you’re looking for the most power out of your setup. It will even fit up to a 5” down pipe if the traction bar has enough clearance! However, it will work great with more mild turbo setups as well.

Obviously this manifold is not for the faint of heart, and the customer should understand that small chassis modifications may be necessary.

The manifold requires the use of a readily available alternator relocation bracket.

Specs:

• Schedule 40 304 stainless steel piping
• CNC milled mild steel flanges
• TIG welded by hand and backpurged for a clean contamination free weld.
• Guaranteed to fit, and warrantied for life to the original owner.
