if it further helps ontop of boosted_r32's comment... i had a set of xforce extractors on my civic... and they fit perfectly.

Everything was perfect from O2 sensor location to original bracket locations.

and the difference they made... well worth money spent! im sure the dumps are gonna be just as good!

How hard is it to fit dump pipes yourself?? Whats involved?

Hoist

Lots of tools

Full day if you've never done it before

You gotta pull the rear dump etc off, then the rear turbo, then the front dump, put the dump on and re-assemble.

You can do it on a trolley jack, but it takes forever as you have to go from over/under the motor on many occasions.

Simply put, if your not a good hands-on person, a GTR dump swap out is a workshop job as it’s a fair mongrel of a job.

Once you've done it a few times you can peg it back to a few hours, but you wont do it in a few hours off the bat IMO

Im about to put my turbos back on with X-force dumps. Thing is.. it doesnt look like my exhaust pipe from the dumps to the cat will line up with the x-force at all.

Anyone else have this prob?

Im pulling off stock turbs with stock dumps and the pipe is a 3-inch something or other. I assume its also stock

to r31 gagz, were you running stock or aftermarket dumps?, and are adj cam gears more worthwhile than cams?i want close to what you have on a safe tune...oh and were you using power fc d-jetro, or just normal? we got a good tuner here,and im about to buy an aftermarket ecu....

thanks.

im currently changing my dump in my gtr as well. however i couldnt get it right. the problem is when i compare the stock front and rear dump pipe, they are in fact not the same shape. but the stainless pair i have just bought is in the same shape. the stainless pair is identical. does this sound right? or are they supposed to be different in shape (the aftermarket ones)? the problem im facing now is the rear dump pipe is in the way of the gearbox housing.

when i look closer to the stock manifold i can see that they are not the same too. is that right? if yes does that means im having this problem now becoz i put the rear manifold on the front and vise versa?

plz help guys. any info would be appreciated. thanks :)

well you are half right. dump pipes are different front to rear but the manifolds are the same. If both dump pipes are the same there is a problem.

I had a really crap set of ebay pipes recently that also fouled on the gearbox. very frustrating they were on and off about 5 times to be modified, grinding the end off studs, bashing the wastegate pipe to clear the rear intake etc etc.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • 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/
