also the TURBO,will a t04e with external gate fit straight on? not goin for a huge power diff,just new turbo,what fits,looked around but there is no def answer.if i decide to keep car what stainless manifold would fit and different turbo,if i can find these out i might keep my car :dry:

Got links to these 3 dumps?

I've got a T3/T4 turbo I'm getting rid of. Bolts straight on, but is oil cooled only.

The split dump in the first link will not fit, it hits the floor due to being a straight run of pipe

The bell mouth in the second link, which is a direct copy or the same as a x-force pipe will fit

The x-force are $330-350, The JJR one is $199 and good value. Just hope they have sorted their flange to turbo warp problems out with these new pipes.

G`Day all having just read this i must add,I have fitted bellmouth dump pipe to my series 2 & would say that they DON`T fit we ended up cutting it throw the gut`s & rewelding it as it hit`s the body now some one will say who fitted it is hopeless well he work`s for a performance shop & build rollcage`s & fab`s lot`s of stuff for motorsport, zrost for lot`s of different car`s ,he said this is the best way to do it unless your be rooting around for age`s.IT has made a great difference to the car & would tell any one to get a 3in bellmouth dump,i drove to kalgoolie on saturday & back the same day,& found that fuel econemy is much better 10ltr per 100kms at 140 + most of the time so yes very pleased with my mod 3in till bend then 4in with rsr rear muffler,it has made a big difference to the way the car performes.hope this will help some of you .cheer`s chuckie.

Darrin,

As I have the JJ model, could you expand on your comments please.

When I went thru the dump pipe fitment drama's, search for old thread. the split dump that I bought was not well made, it was warped 3 different ways due to the flange materail being too thin, but was told they were working on fixing the problems.

Thanks Darrin, I'm fine then, mine is a singgle Bell Mouth. Incidently on the cruise last Sunday I was down to about 13l/100

That is 3l/100 less than before I fitted the dump and X Force.

I'm wondering about going 4" cat back without a resonator"?" and a bigish cannon. But it may be a bit noisy.

The R33GTST Group Buy split dump fitted perfectly on mine, which has a Magic cat and a modified Nismo R32GTR 3" exhaust. I ended up using that particular split dump on the R33GTST and the Stagea now has a Performance Metalcraft hand fabricated (work of art) split dump on it that was originally on the R32GTST.

More to the point;

also the TURBO,will a t04e with external gate fit straight on? not goin for a huge power diff,

A T04E, doesn't fit straight on, especially with an external wastegate. And if it did it would give you a huge power difference.

looked around but there is no def answer

Of course there is no definitive answer, everybody has different requirements and tastes. In my case doubling the standard power output at the wheels via a highly responsive GCG ball bearing high flowed RB20DET turbo was the perfect choice. In Brad's case, quadrupling the power output via a T04Z suited his requirements.

Take a proper look at what everybody is running and why they chose it and I bet you will find a combination that suites your requirements.

Cheers

Gary

Since fitting the new dump and cat we went on the Qld cruise and general running around including two trips up Henri Robert, a total of 510ks for 57.5 litres. Thats about 11.3L/100.

  • 4 weeks later...

ok although everyone has different turbo setups,could everyone/anyone post what turbo you have and if it bolted up directly,if so what dump pipe did you use etc,will be looking at turbo in next couple of weeks,with minor work needed,thanks everyone

GCG hiflow of standard turbo bolts straight on. (230-270rwkw)

HKS GT-RS bolts straight on. (230-270rwkw)

are the most likely bolt on turbo choices.

there are so many choices depending on your power target/requirements including HKS 2835 ProS or HKS 3037ProS kits but each increase in power level = more $$'s

a search of forced induction will show these threads come up a zillion times and the answers are pretty much always the same.

I use the 3" JJ bellmouth for my Series 1 Rsv4 1997 auto awd rb25det Stagea http://www.skylinesaustralia.com/forums/JJ...RB-t204414.html

great value, and Ive heard the bellmouth flange weld has been fixed and is better (3yrs ago mine needed a $100 job to relweld up the flange properly)

fits no issue (apart what I had, above, almost 3years ago), is stainless steel and after 30-odd months looks new still.

fitted standard 3" R33 hi-flow cat converter, new oygen sensor, and the 3" cat back system I already had (cut off 3" Fujistubo muffler and welded on sraight thru kakimoto gtr muffler)

used stock turbo, now using stock highflowed Slide turbo

ppl in front and behind in yesterdays stagea cruise commented on the induction noise (k&n pod in Maxx r34 airbox with foam internal insulation, stock snorkel, bass junkey rad.air-guide, return feed apexi fmic)

I personally think its the steel wheels and massively ported front/rear stock housings :(:D

so besides those hks and other very expensive turbo's,there are no known others that are a direct fit?? why are brand new turbos so cheap on ebay?? and yes i know if i want a good one i should expect to pay good money but i am only after a new turbo rather than massive power,as long as its a little better than stock... :D

    • Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?
    • After 23 years of owning a Skyline, finally had the latch go.  Followed this guide,  works like a dream again. Great Guide 👍
    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄
