Turbo Manifold Mockup Kit 1.5" NPS SCH10S (48.3mm OD) – 219pc WORKSHOP

Turbo manifold and header mockup blocks for 1.5" NPS schedule 10 pipe

Our largest kit in the larger pipe size. 219 magnetic mockup blocks matched to 1.5" NPS SCH10S (48.3mm OD), for shops building high power multi-cylinder manifolds and headers where primary diameter is stepped up and the routing is anything but simple. Enough blocks to model an eight cylinder layout in full, or to keep two projects mocked up on the bench at the same time.

What it does

• Model complete multi-cylinder manifolds and headers in 1.5" NPS pipe without running short
• Keep more than one project mocked up simultaneously
• Design equal length headers where primary length actually matters to the powerband
• Model the merge collector and confirm the collector angle before you cut
• Work around tight engine bay clearances, turbo positioning and wastegate routing
• Produce an exact cut list so you order the right bends and waste no stainless

Pipe compatibility

Matched to 1.5" NPS schedule 10S stainless pipe, 48.3mm outside diameter. Pipe is sized by nominal bore rather than outside diameter, so 1.5" NPS pipe is not interchangeable with 1.5" OD mandrel bent tube.

Header and manifold mockup, step by step

1. Mount the flange adapters to your head flange or turbo flange
2. Snap bends and straights together, rotating each joint to clear obstructions
3. Adjust until every primary is routed and the lengths are balanced
4. Count your blocks for the cut list, then cut, tack and TIG weld to match

Specification

Made to order in Britain

Every kit is produced to order in our own workshop rather than pulled off a shelf. That is why we can supply centreline radii and pipe sizes the imported kits do not offer. Need a size that is not listed? Get in touch and we will quote it.

FAQs

Can I use this to design an exhaust header?
Yes, as long as you are building in pipe. These blocks are dimensioned for 1.5" NPS schedule 10 pipe, not mandrel bent tube sized by outside diameter.

Do I need WORKSHOP or BUILDER in 1.5" NPS?
BUILDER at 136 pieces covers most single manifold builds. WORKSHOP at 219 suits eight cylinder header work, or a shop with several jobs mocked up at once.

Can I add to this kit later?
Yes. Straights and 30, 45 and 90 degree bends are all sold as add-on packs in this same 1.5" NPS SCH10S size, so you can top up whichever angle you run short on.

Can I run two projects at the same time with this kit?
Yes, that is largely what the extra volume is for. Most single manifolds use well under half the blocks.

Are blocks interchangeable between the 1.25" and 1.5" kits?
No. Each pipe size is a separate system and the blocks will not connect across sizes. Order the kit that matches the pipe you are building in.
