I dont want to step in where i dont belong but with log manifolds generally you can only run a 2.5"=>3" DP to keep A/C. If you are doing a full HMT setup i doubt you will find the need to do anything larger than 2.5".

 

I've got 3" into the turbo, 2.5 to the tb, and I'm shooting for 3" to the cat (and later all the way). You don't need huge pipes going to the tb since the air is being compressed, but the super-heated air coming from the engine needs larger diameter piping due to the fact that it is expanded. And if you are forcing twice the air (as stock) into an engine, you need twice the piping coming out if it is going to flow well, right? Ok, no log mani is gonna flow THAT well, but it is all about compromises. That is why I've always thought bigger is better in a FI app. I want to run 3" if possible. If it isn't possible, 2.5 may have to do, or I may elect to use the external gate. which would remove some of the exhaust vomume from the dp. The only problem with the external gate is that I'd have to find or fabricate a flange for my T3 (mercedes type) which isn't gonna be that easy, so I'd like to use the internal gate. As for the pic, there wasn't one.

EDIT: What is wrong BIGWIG, need your paci? reread my post and figure out what I was saying before you respond. That is it for me, it ain't my thread.

 

Dude...can you read? i was just talking about a downpipe. I'll say it again because obviously you are a little slow.
IT IS NEARLY IMPOSSIBLE TO RUN A 3" DOWN PIPE OFF A LOG MANIFOLD AND KEEP YOUR AIR CONDITIONING. YOU WILL EITHER NEED TO RUN A STRAIGHT 2.5" DOWNPIPE OR HAVE IT 2.5" AND FLARE OUT TO 3".

 

I have Mercedes down pipe flanges

 

hey shitbird you didnt reply to my e-mails so i was wondering when your gonna send me that 20 dollars for shipping so let me know asap or contact me at sxymike4u@aol.com thnx again -mike

thnx shitbird for being so cooperative and responsible throught the deal -mike

 

dude shitbird did you get my email?
i just want a log manifoldw/ a t3 flange
possibly keep a/c email me back jdmcrxsir2001@yahoo.com
i know your a busy guy
oh yeah it's for a b18b1 in a crx

 

ummmmm yeah, i don't need a manifold or anything, but i just wanted to say that shitbird is the man

 

email sent. can you check email please?

 

Can you do log style with external 35mm Tail Wastegate for same price? Thanks,
Matt

 

Dudes, sorry to rain on your parade, but he ain't making manifolds right now. Unless he posts a response, forget about it until February.
It sucks, because that was an awesome deal. I'm having to go elsewhere or make my own now
Anyway, quit posting until he comes back...
