PMO Carb Manifold Height Options

[defianty]

The engine I have for my six conversion is a 3.0 and was rebuilt and used as a spare for a guy who had an original RS. The engine was used whilst the RS engine was rebuilt. Once thing led to another and he only covered 1,000 miles with the 3.0 before the RS was complete.

The 3.0 had PMOs and I bought them with the engine. When I collected the engine all of the ancillaries were boxed separately and only today, almost a year later, when trying out the carbs for size I thought to myself - "Those look tall!"

Amongst the paper work I can see the 'Tall' manifolds were ordered and a quick google has revealed that these are going to be too tall for a 914, they measure 100mm. To big?

I'd speak to PMO themselves but I'm not sure how they'd be as I'm not the original owner. That and I don't know how to send a fax in 2017!

Pretty sure there will be clearance issues,when I was running K&Ns I had minimal body clearance @ the alloy top cover,not sure about the rain hats ?.
Mine are stock Porsche manifolds they are roughly 60mm high, I now have stock aircleaner on and I had to relocate one hold down clip on the RH side rear due lack of room at the bulkhead.
Great point about conversions,my motor is a little lower than it should be and I have altered the front mount once already.
Seem to remember Larmo (Lawrence ) mentioning PMO manifold height with his build...maybe he will chime in and comment ?
Good luck.
