And you expect your manifold to control boost thru a pathetic 38mm port? Its been around for yrs, to get perfect boost control you need larger diameter pipe for the wastegate from the collector.( reason ppl modify the chinese manifolds to 50mm or bigger ) If u done ur research prior then you wouldnt have such problems.
my nz manifold bolted up perfect in everyway and works wonders. who gives a flying shit if it doesnt look pretty like a 6boost. cause everyone is going 2 get a fat over the awsome collector when the fkn turbo is bolted on.. haha ive had my whinge. im out.
here is a few photos of my rb25 manifold that arrived a few days ago
replaced it with my cheap chinese thing.
has a 50mm port for wastegate and im running a gt3582r turbo
just waiting on dumpipe 2 be modified 2 suit.
maybe he should re tune on 91 octane so it can be a good result for all the complete wankers out there lol.
should he run low boost aswell just incase ppl who buy one of these turbos dont want to run the boost he is testing on??
