I bought a genuine garrett gt3582r yesterday, .82 rear, 4 bolt. I also ordered a 6boost manifold and 50mm wastegate which will arrive in 4 weeks from today. My car currently has; Z32 afm, 910cc at 3 bar JECS injectors, walbro 341 fuel pump, power fc, tuning crap, hd clutch, 3 inch front pipe, stock cat, 3 inch kakemoto catback. I have the car really well tuned currently on the stock turbo at 14psi. No knock anywhere and nice afr's. So I'm just after advice on putting this setup together. I can assemble it now worries. More just after tips for tuning ie: more timing and less fuel down low to fill up the lag gap? And ideas about afm placement? I have read a bunch of stuff about afm placement and am leaning towards leaving it in the stock configuration. I'm getting some oil and water lines from ebay. Are these as simple as bolting in? I read something about a 20 micron oil filter for the turbo. Anyway any info/ideas would be good.

:cheers:

The exhaust will have to stay the same for now as I have already made the missus mad with my spending. Swapping the cat is on the cards. The exhaust will get replaced next year when the motor gets changed. Ebay lines are crap aye? Where's a better place to get them? I know a guy who works for enzed. I spose he could do it.

EDIT The engine internals are going to stay stock for 12 months so it wont be wound up too much. :whistling:

I am assuming the turbo intake is 4", if so I wouldnt put a 3" afm in the intake, too restrictive on that sort of turbo. Yeah as said above exhaust will be restrictive, both cat and catback.

hardly, leave it in the standard position, make sure your intake pipe has a bend in it and you'll never have any troubles.

as for tuning, same basic principles apply as with a standard turbo, you want a gradual dip from cruising afr's down to 11.5-12:1 at peak torque/full boost then 12:1 to redline and as much timing you can run without inducing knock or going past MBT

Kando dynamic do quality line kits for about $100. I would NOT call them ebay crap. Have used them myself in the past.

As for your setup, aslong as you have a decent gate (tial mvr or similar) and you replace that cat, you will be cool. A decent 3" cat is only $189, why skimp?

Also you did not mention an FMIC, make sure you have one of these too.

045how lol I still have the 2 stock turbos and the t3 flanges arrived yesterday. I still dont have the head flange yet. Seeing as the rb30 in my shed is getting stroked next year I was thinking about keeping the flanges and putting another gt35 on it. We'll see. Jonnohr31 The missus is getting to be a good co-tuner so it should only take a good weekend to get the tune 90 percent. R31nismoid I'll go see the guy this arvy and let him know what I need. Only 3 weeks and 6 days to go. I already told the boss that I'm taking a sicky to put my car together :laugh::sick:

I'll have a sus of the line kits today. I'm getting a turbosmart 50mm gate, its coming with the manifold from Kyle. Lol the cat will get replaced. I have a 600X300X100 front mount. Sometimes I forget the some of the stuff I have put on the car :wacko:

The actual hole in the intake of the turbo is only around 2.5 inches. Its just the outside fitting that is 4 inches. Also you say cat and catback need replacing. Yes the cat will be too small. However it is more important to have a larger section of pipe at the start of the exhaust rather than at the back. If I were to replace the exhaust in sections I would start from the front and work back. Eg: Disregarding the cat (cos its getting replaced), I'd replace my 3 inch front pipe first.

Everything in that setup is too restrictive for the potential of that turbo.

Its even too restrictive for a GT30R.

Not everything. The injectors flow 910 cc at stock pressure and 990cc at 4 bar. The afm is good for 360 kw or so. The intercooler is well big enough. I thinking about the future. I have an rb30 in the shed that I have almost ready to put with the 25 head and the missus and I have decided to get the spool 3.4 stroker kit next year. I have all the necessary bits on the car to make a stack more power except the turbo. Its better that I run this turbo near the low end of the efficiency range for now than flog the crap out of a smaller turbo that will get replaced in 12 months. Hey, I can afford to do up the car but I dont own a bank :whistling:

    • 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 🙄  
    • From everything I’ve heard you’ll be waiting a long time for  the parts to arrive 
    • Have you looked at the workshop manual?
    • Hmm. I've gotten pretty good outcomes from talking to them about things that I've had go wrong or ideas for improvement. Have had a lot to say about the R32 FUCAs, and they have sent out some replacement parts for those, gratis, on a couple of occasions. Mind you, I have bought a couple hundreds of $ of replacement rod ends for them too!
