hi, i been trying to search but havnt come up with anythin, i would like to know if anyone has got rid of all that platic n rubber intake and changed it to metal or different piping? or if it is possible? i have got a NA r34 and want to get rid of all the stock intake because since i fitted my extractors some of it is now startin to touch the extractors. Any info/links would be good

since the original post on this topic, I have done this modification to my R33, it now has a 3" mandrel bent intake pipe.

I can't say you will loose power but you will loose a bit of low end torque and fuel economy, but on the up side the intake noise sounds awesome at high revs :(

Rach, you know people are gonna be asking for pics so if you can that would be great.

I'll probably have more questions for you after seeing your setup as I too am planning the metal intake pipe except I will be swapping out the 34 NA airbox for a 34 turbo airbox. I also am yet to have my headers and custom exhuast done.

righto here are a couple of pics, nothing fancy under the hood might look a bit weird with the heater wrap around the intake pipe, but ithere's a practical reason for it, it stops the heat soak issues I was having.

Your catch can is installed incorrectly.

yep I know, it was set up like this by my mechanic and it was set up wrong, it does absolutly nothing the way it is set up, I'm looking into getting a bigger Catch can (2L) that is suitable for motorsport use, and getting it installed properly so nothing is vented back into the intake, but the problem is to find a place that has enough room for it to be mounted.

Correct Install

PIC HERE

many high ranking sau members seem to think this is the way to do it.. Seems that the reason is because at low speed and off boost the pcv is sucking air in through the catch can.. solving nothing

I think your method is best use in a atmospheric venting catch can

    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
