my first atempt at making a manifold for my 998 turbo looked ok but has cracked in 3 places after less than a 1000 miles. i used a old LCB and a mig welder to make it, any suggestions on how i could make it better/ stronger??? thanks neil |

Sounds like more of a welding issue than a design issue, would need pictures to confirm but probably just not enough penetration. -1974 Mini 1000 - BRG Turbo Build Soon to come

Also the materials used where probably not up to the job. I doubt an LCB was designed to bear the load of a turbo on it. Edited by apbellamy on 9th May, 2012. On 11th Feb, 2015 robert said:

A little bit of searching on here will reveal that using an LCB as the ex. manifold with a turbo will result in it cracking.

the design shows a distinct lack of imagination, talk about starting off with a clean sheet of paper, then not bothering to fucking draw on it,lol On 20th Apr, 2012 Paul S said:

I've been working on my new manifold this morning:
