I’m fitting an rb25 turbo on my RB20 and am wondering what the best sounding outlet pipe is. I’ve looked at the tomei, but I’m not really looking at spending 300 usd for an outlet pipe. What else do you guys think? Also looking at downpipes aswell.

Outlet pipes ( to intercooler?) don't make a sound. Find someone with an RB25DET and copy their set up with stock (second hand) gear. Yes get a three inch downpipe.

Oh you americans.

Doesn't matter what 'outlet pipe' you use, it's attached to an RB20 so going to sound good.

too right!

That's a R31house takoashi MAX manifold.... they are by far the nicest looking manifold for an RB and now long discontinued for the new version which is a direct replica of the gts-r manifold ? 

But yeah anyways...I have a gtsr manifold that's unfortunately been re-flanged and had a gate welded to it then removed and repaired at some stage....Cost me a packet too.

Would looks amazing if it wasn't that terrible chrome colour ?

Sidenote: My manifold sounds absolutely amazing but i cannot provide evidence as a truck crashed into the car the second day of driving it and now looking like its going to be written off :(

They're made from stainless just like the original gts-r takoashi and would discolour almost instantly with the first few drives and heat cycles. There's actually a picture somewhere I saw last week on the R31house owners blog of the ver3 test manifold after it was test fitted and ran for first time on the his R31 and it's turned a nice heat treated purple/brown/blue - ish colour...

Long time since I have been on SAU but I might be buying a new skyline.  Definitely  keen on a GTS-R manifold this time. The R31house takoashis are amazing. 

I noticed a fabricator in Australia is now making replica R31house takoashi style manifolds. The business is "speedtek". They have stainless versions on their Facebook page, and a steampipe version on  ebay.

Does anyone here know anything about these, and if they sound the same as the original GTS-R / R31house variants. The runner length and merge collector style is essential to the sound these manifolds make, so hopefully speedtek have those lengths correct. The stainless versions look perfect to me.

 

The good thing about a gts-r or takoashi  manifold is they  sound completely  different to any other turbo manifold, including equal length 6boost style ones... 

Some pics of these speedtek ones I have found are attached.

Here's my favourite video of a GTS-R manifolded car. Rb20, itbs, gtsr mani, pure madness. This guys youtube account is pure exhaust porn for anyone interested.

The manifolds look decent but speedtek don't have a good rep for various reasons. Some to do with quality and some to do with the dodgey guy that runs it. Can't remember the details about him right now but im sure some Google investigating will uncover it.

Yep, some googling has revealed some pretty unsavoury stuff. Surely they  can't be that hard to make though? It's strange no one else has ever attempted them (excl  R31house).

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Hi all. So I have my GTR on the lift and have been working on it a few days and yesterday I unpacked the frontpipe that was wrapped with heat wrap stuff, because part of it was breaking down and soaked in oil. Noticed that the pipe itself does not actually look like a Mines, despite it supposedly being a Mines. But I could not find any fronpipe online that looks exacly like his, and I don't think it is a custom one. My amateur measurement also showed the two pipes are about equal length, so maybe this is just an old version of the Mines pipe? Would appreciate insight on this by the enlightened folks. greetings from Germany

      Yeah. If I plug the connector in and connect the vacuum lines, I assume worse case scenario is that it simply doesn't work? Yep PFC.

      I would think that rather than attempting to perform an engine swap, with all the difficulties associated with doing so in a country where the raw materials required are harder to get hold of, I would just build the CA20 for boost, find an EFI manifold for it and either add a turbo or a supercharger. Or both. You replace one set of difficulties with a different set, but I know which would be more fun.

      Well, a proper aftermarket ECU** SHOULD be set up to run the purge solenoid, same as the factory ECU would, so that the tank breather system continues to operate the way it is supposed to. I have no knowledge of whether the PFC (which is what I assume you mean when you say Apexi) has an output (and internal logic) to run the purge solenoid. If it does not, then given the product design intent for the PFC, which is to be a plug in replacement for the stock ECU, I would consider that a massive failing on Apexi's behalf and would be another reason to think that they were a half-arsed solution to the problem if programmable management on RBs. I would suggest that since Nistune came to market (which is a LOOOOONG time ago now) there has been no valid argument for choosing a PFC, especially if the PFC can't do things like this.   **ie, Haltach, Link, Motec, etc
