i gota just jap... was a bit of stuffin round but wasnt that bad, i left my heat sheild off aswell... not guna do any hard will it? just make my engin bay a little hotter if ne thing

I've got a 3" split dump on mine which doesn't have a mounting point for a heat shield. The guy who made it says it doesn't need a heat shield; apparently won't cook paint or melt aircon' drain pipe. I've run like that for a week now and I haven't noticed anything bad so far, just less ticking/heat noise when I turn the engine off which I put down to less cast iron in the system now :laugh:

  • 3 weeks later...

Well I've just done mine, 3" Bellmouth front/dump from JJR. Wasn't too bad i suppose, would have been easier if I had someone to help though. Couple of tings that I'm a bit concerned about.

1. Boost definitely sounds louder (i.e. whistling sound) and comes on quicker too, but definitely higher pitch? Is that aright?

2. The O2 sensor couldn't tighten up all the way, it's tight but there is about 2 more turns to go all the way... i.e. the o ring is loose. Badly machined threads from the JJR dump pipe? Is this a problem, as it is tight anyway? I don't think there's any leakage.

3. I only managed to put back the main heat shield with 2 bolts out of 5. Nothing to tighten it too. It's secure. But the rest of the pipe doesnt have any heat shield/wrapping? Should it?

4. Only managed to put on 5 of the 6 bolts back to turbo, one of them just refused to catch. Others are on pretty tightly, will there be leaks?

Cheers.

Nick.

nick,

I wouldnt be to concerned about the higher pitch turbo spool sound as its now a stainless frontdump instead of the mild steel/steel one.

As for the 02 sensor aslong as its not leaking i cant see a problem at all.

Heat sheild shouldnt be a problem just check the hoses around the area for the first few weeks for any unecessry heat attack :cool:

which one of the 6 bolts couldnt you do up? im huessting if you looking from the top standing next to the front left wheel the 2nd one down from the top on the sie your standing on? its a prick! it wasnt tight when it was on adams and as you could tell by the gasket their were no leaks :yes:

heya chris,

yeah that's what i was hoping.

It was the the middle closest to me that wouldn't do up. The weld is in the way i reckon.

I added a thin layer of exhaust cement so hopefully that would help.

love the spooling up sound now though :D

i just automatically assume the worst as i'm pretty rubbish when it comes to things like that!

Yeah I noticed a higher-pitch spool sound when I changed my dump pipe; I also had the turbo hiflowed at the same time (gcg) and it sounds different - not worn turbo squeal now, but spool noise. The stainless dump pipe is a fair bit thinner than the big cast jobbie that was there from the factory, and I think it lets out a fair bit more noise.

To get all the bolts done up on my turbo (I had the luxury of having the turbo off to begin with) I fitted it off the car, and dropped the turbo and dump pipe in together and just did up the two bolts on the dump pipe -> cat.

The studs/nuts they put on the turbo were pretty crap and a couple siezed and one stripped, so I replaced that one with an original bolt anyway.

Hey guys,

I have just fitted a 3" dump and hi flow cat on my Stagea. Its definately louder than before. I also stripped one turbo bolt, i got 5 bolts on no worries but i think i am getting a leak.

Is there any risk running the car with a leak at the turbo/dump pipe mating surface??

Also where can i get some new turbo bolts for a stock turbo??

Thanks

^^^ nick, get a short length of garden hose and put one end to your ear. move the other end around the engine bay where you think a leak may be and if it's there, you'll hear it :down:

Cool, i'll try that. Don't need to rev the engine or anything?

    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
