Title: JPM Header. Post by: UltraOrange67-2443 on August 07, 2017, 23:48:38 pm Anyone know what size tubes are used on the stage 2 and 3?
Wondering which one will be best on my motor. Cheers, Nick Title: Re: JPM Header. Post by: hotstreetvw on August 08, 2017, 02:58:24 am Stage 3 is 1-3/4, 2, 2-1/8

I'm building a 2919cc motor. I've been looking at having a custom header made in 2" pipework. Cheers, Nick Title: Re: JPM Header. Post by: hotstreetvw on August 08, 2017, 19:36:51 pm I think 2" might be small but it will depend on the heads and intended use. I would go to burns website, fill out the engine specs, it's a bunch of pages long, and have Vince spec out your system. Buy your collector from them and get to building.

Its a street motor. 90 x 101.6, JPM MS250 Heads with 48 x 38 valves, 48mm IDA Throttle bodies and just over 17mm of valve lift. Not a high rpm motor. Cheers, Nick Title: Re: JPM Header.
