hey guys, just want a bit of advice here, my car is currently gettin worked on at the moment and am hoping to hit arounnd the 330rwkw mark on 19psi, ive done every mod i thinks possible. How long do u do u guys think the internals and rods will last. Or should i forge the internals and all that sort of stuff as well or just wait till the engine goes then do it when its time to rebuild.

bit of background of the mods.

Vipec computer

Garrett gt3082r

cams

plenum

550 cc injectors

front mount

brass button clutch

walbro fuel pump

greddy boost controller

and the obvious external wastegate etc etc

any advice or previous experiences guys would be awesome

cheerrss

you will be very lucky if u pulled 330rwkw from this combination on a standard engine

i use to run a gt3040 (gt3082r) and i only jut managed 329rwkw at 19psi on my old turbo setup but that was on a forged engine

plus your injectors will nearly be at 100% duty

if i was u id maybe put some camgears and cams in as the turbo you are running will be laggy with the .82 exhaust housing

what exhaust manifold are u using???

you should tune it to around 250--270rwkw max on a standard engine to be safe and watch your knock levels other wise you might blow a piston ringland or put the rod through the block

It'll be fine. It's all about the tune and how you drive it. Dont bash it off the limiter every day, Dont over rev it if you can help it and smooth transitions between gear changes helps everything. A few less psi wont kill you to loose so maybe run 17psi, you might loose 30 kilowatts but just for peace of mind. But apart from that, Like previously mentioned...you'll get defected before it blows up.

^^ Yeah all comes down to the tune. Forged internals wont make you anymore power, They just make it reliable.

Much over 400kw with a standard bottom end and you're asking for trouble.

Just to make it safer and to keep it from pinging i would be looking into water/meth injection. Not only will it make it alot safer but you can also add alot more timing into it aswell as a few more psi and make more power. Last time i checked the kits where around $900 from rice racing.

Darren (SLO-030) uses that kit and went from 370kw to 450kw with just more timing and 3 more psi on pump fuel.

Get the second map on the vipec tuned for e85, keep the other as a safe 98 octane tune in case you have to buy fuel between e85 retailers. Make sure it is a slightly rich tune on the 98 premium so that if you run a bit of a mix you won't be leaning out due to e85 being less dense.

I want to do this to the stag in the future, just with an emanage instead.

  • 5 weeks later...

I may have been told bullshit. But my mate was working on a 33 with 385kw at the rears. was running 25psi, threw 2 conrods through the block the size of a fist, tore the engine mounts aswell.

Cant remember details, but was fairly hardcore., high mount, ase plenum, EMS stinger, coils, Injectors and the shit. Internally stock apart from cams.

shaun at boostworx did it bro, ended up getting a howtech(dono the spelling) computer instead of vipec. Apparently the engine should be ok for a while,

just cruise on 12psi and only goto 18psi here and there, but it gets addictive. lol, heres a pic

ahahah thats what he said to me then 2 months later they leaned it out on their dyno and blew my engine, bye bye piston 6 ringland :)

just keep an eye on ya engine warning light since u cant see a knock reading

can you post a dyno sheet and air/fuel ratios??

    • 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/
