i read threads on here about split dump pipes vs normal 3" dump pipes and it looks like the split pipes have a little more midrange,but the full 3" dump keeps pulling after 6500rpms unlike the split system.

From threads ive read on here^^^^^^^^^^^^^^^

ive been in a 32gtst with gt30r turbo + screamer pipe & it sounded awesome.

i've seen plenty of home made screamer pipes for stock turbos on here for sale and was told the gate only opens after your actuator has reached the stock psi limit (7psi i think) then the gate opens for the screamer pipe.

i myself have a full 3" dump and front from BATMBL

but wouldnt mind trying a screamer pipe after my turbo is hi-flowed.

conclusion: a screamer pipe for a stocker is like a BOV for a stocker.

IMO

My car when it had the Ext Gate.

NOTE: I've never head an internally gated turbo sound even close to this.

So dont expect to get anywhere near what the video shows

cheers

aaah, memories

aquariuz6 - mate I have a 3.5 inch cat back system which needs a new muffler.

I'll sell it to you for $120.. a 3inch muffler will cost you about $200

say $50 for fitting

for $370, you will have a car that will sound great and actually improve performance.

a screamer pipe is higly illegal in NSW as it is sending exhaust gases out without going through cat.

In NSW, the fine for NOT having a cat (which is what a screamer pipe essentially is) is $10,000.

now.. you tell me. $370 for improved sound and performance? or $10K for nothing..

if i were to install a screamer pipe... is it possible to install a bov?

just curious because of planning on buying one soon... but i thought that it wouldnt be no use since the screamer pipe already vents the gases from the wastegate??? that true???

bov's and wastegates are seperate things althogether, a wastegate vents air away from the turbine wheel to prevent it from over boosting, and a bov will simply open when u back off to prevent the air going back through the compressor when the throttle is closed

i know the fines 10k for no cat but what is the fine for a screamer? i have mine set up with a flange so i can easily have it on or off coz i luv the sound but dont look forward to the fines even though it is very hard to see it, so yeh anyone know the exact fine for them

Ok, you have things totally backwards as 2BNVS said..

www.howstuffworks.com

have a solid read there. If you are still not clear.

But to go and actually talk to a workshop mate as i feel you could be purchasing parts that you really dont need and wont benefit the performance of your car

doesnt a screamer pipe only loud when the wastegate opens?

so if i were to control my boost... not reving over 4,000 then that my wastegate shouldnt open.... or does it?

btw all new to this turbo side of cars...

also since i have a stock rb25det engine, what good would installing a bigger wastegate to my stock turbo do for me?

i think it wouldnt do me any good anyways because arent the stock turbo's ceramic and can only withstand 12psi max boost before causing any damages?

    • Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters. 
    • I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix. 
    • 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).
